9C19878F705DFFE2FF861B46FA66B161.taxon	discussion	Notes: Phylloporia afropectinata is characterised by perennial, merismatoid basidiomes with multiple downward proliferations of imbricated pilei (Fig. 2), variably sized, and reaching, based on our observations, up to 25 cm wide. It is so far the species producing the largest merismatoid basidiomes in Phylloporia. Corner (1991) provided likely the best modern description of the development of the merismatoid basidiomes in Phylloporia, and our description are, partly, adapted from him. The hyphal system is of uncertain classification. In the classification scheme of Corner (1991), it would be best described as dimitic of the second degree (d 2), with sclerified hyphae, as in P. weberiana and P. chrysites, both sensu Corner (1991). However, dimitism of the d 2 degree is not entirely satisfactory by omitting the intercalary, very thick-walled hyphae. The sclerified hyphae of limited length originate from a generative hyphae, occasionally from a mediate hyphae, and are either terminal or intercalary, then reversing to slightly thick-walled, generative hyphae (Fig. 3). It could be also considered as intermediate dimitic, following Pegler (1996), or with sclerified, supporting hyphae following Clémençon (2012), as adopted by Ferreira Lopes (2018), e. g., in P. pectinata sensu stricto or in P. ribis sensu stricto. Phylloporia afropectinata, hitherto, is known exclusively from a small-stemmed Meliaceae, Turraea sp., in a single spot of mid-elevation (~ 2000 masl) Afromontane Forest (Kindt et al. 2014), at Mount Elgon, Western Kenya. The identification of the host could not be confirmed in situ, nor by DNA sequence data. It is referred to as Turraea cf. holstii. The basidiomes emerge from different tree organs, from surfacing roots to, and predominantly, trunks and the main lower branches (Fig. 2). Locally, the species is widely distributed, concomitantly to its host; it infects almost every individual tree present in an immediate neighbourhood. This might be linked to the locally gregarious habit of the host, forming small patches. Its distribution range in tropical Africa is still unknown. The species could follow its host over the Eastern Mountain range, where it is widely distributed, although it may depend also on other ad hoc environmental parameters. In a phylogenetic perspective, the closest relative of P. afropectinata is shown to be, hitherto, the western African P. beninensis, that is only known to date from Benin (Olou et al. 2021). Both are related to a specimen originating from Australia and tentatively identified as P. pectinata (Australia, New South Wales, Kurrajong, R. Coveny 113, on Rhodamnia rubescens, Myrtaceae, O, CANB, Wagner & Ryvarden 2002). These three species form a well-supported clade (Fig. 1).	en	Jerusalem, M., Amalfi, M., Yombiyeni, P., Castillo, G., Decock, C.

9C19878F705DFFE2FF861B46FA66B161.taxon	description	Outside Africa, P. pectinata sensu Corner (1991) is the taxon most comparable to P. afropectinata, with respect to its biology, macro- and micromorphology, autecological parameters such as substrate relationships, and local distribution. Both species share the compound, merismatoid basidiomes, reaching up to 15 cm wide in P. pectinata sensu Corner (1991). They both grow from small-stemmed trunks, and have a very comparable pattern of occurrence at a local scale. While P. pectinata sensu Corner (1991) was found on “ almost every tree ” of the small-stemmed, understory Timonius flavescens (Rubiaceae) at the ridge forest of Gunong Panti (Southeast of Johor, Malaysia), P. afropectinata was emerging from almost every individual of Turraea cf. holstii growing in an immediate neighbourhood at Mount Elgon, Kenya. Phylloporia pectinata sensu Corner (1991) and P. afropectinata differ by their pore size (60 – 90 µm diam., ~ 10 – 12 / mm vs 90 – 115 µm, 8 – 9 / mm), ellipsoid vs broadly ellipsoid to subglobose basidiospores (2.7 – 3.5 × 2 – 2.5 µm vs 3.8 – 4.3 × 3.0 – 3.5 µm), host plant (Timonius flavescens vs Turraea cf. holstii), and habitat (Southeast Asian rainforest vs Afromontane middle elevation forest).	en	Jerusalem, M., Amalfi, M., Yombiyeni, P., Castillo, G., Decock, C.

In a morphological and phylogenetic perspective, P. cinnamomea is closely related to P. rinoreae. Both species share also the habitat, which is the Guineo-Congolian rainforest (Jerusalem et al. 2019). These two species differ by their pore size, slightly smaller in P. rinoreae, basidiospores size, slightly shorter and narrower in P. cinnamomea (3.5 – 4.0 × 2.2 – 2.5, av. = 3.9 × 2.3 μm and 4.0 – 4.5 × 2.5 – 3.0 μm, av. = 4.3 × 2.7 μm). The host plant is unknown for P. cinnamomea. Phylloporia cinnamomea and P. rinoreae could be compared also to P. pseudoweberiana, which belongs to the same clade (see notes under this species). These species share the basidiome anatomy and substrate affinities. Phylloporia cinnamomea and P. rinoreae have smaller basidiomes, up to 20 mm wide, whereas they are 20 – 80 mm wide in P. pseudoweberiana.	en	Jerusalem, M., Amalfi, M., Yombiyeni, P., Castillo, G., Decock, C.

9C19878F7055FFECFF8612E6FD85B721.taxon	discussion	Notes: Phylloporia microspora is characterised by seasonal, multiple, gregarious, basidiomes, arising simultaneous from a common base, small- to medium-sized (up to 15 – 25 (– 30) mm long × 15 – 30 mm wide), slightly spathulate to broadly attached with smooth, mostly uniformly light brown pilei (Fig. 7), and 5 – 6 pores / mm. The hyphal system is homogeneously monomitic. The basidiospores are narrowly ellipsoid to shortly oblong, 3.2 – 3.8 × 2.0 – 2.5 μm (Fig. 8). Its sole known habitat for the time being is the low altitude, low rainfall, seasonally dry Zambezian open forest and perhaps, more specifically, the Mopane Forest that should be the local native vegetation in the neighbourhood of Victoria Falls, in Zimbabwe (White 1983, Mapaure 1994). Phylloporia microspora has no close morphological relative in its known habitat of occurrence nor, hitherto, in tropical Africa or out of Africa. In a phylogenetic perspective, it stands on an isolated branch (Fig. 1). To some extent, but superficially, P. microspora reminds of P. flabelliformis and P. gabonensis (Decock et al. 2015, Ryvarden 2019). These three species share the reproduction strategy with multiple, simultaneous, gregarious emergence of short-living (seasonal) basidiomes, light-coloured pileus, the monomitic hyphal system, and the growth from trunks of small-stemmed trees (Decock et al. 2015). These similitudes are only superficially comparable, however. The basidiomes of P. microspora emerge from a common base whereas, inversely, in both P. flabelliformis and P. gabonensis, the basidiomes emerge individually from the trunk. Phylloporia microspora also differs from both above-mentioned species in having denser, hard corky basidiomes, which are much softer, fragile when dry in the two other species. In an ecological context, P. microspora was found growing from Colophospermum mopane (Fabaceae), a markedly xeric species found in the low altitude, low rainfall areas, seasonally dry Zambezian open forest, in Zimbabwe (White 1983, Mapaure 1994). Phylloporia gabonensis and P. flabelliformis were found growing on two Euphorbiaceae (Dichostemma glaucescens and Anthostema aubryanum) in the Western edge of Central Africa, in Gabon, or in biogeographical term, the Lower Guinean rainforest (White 1983), which is a humid to very humid, moisture-buffered, closed forest.	en	Jerusalem, M., Amalfi, M., Yombiyeni, P., Castillo, G., Decock, C.

9C19878F7057FFEBFF8616C6FE10B562.taxon	discussion	Notes: Phylloporia miomboensis is known from a single specimen, growing from an unidentified bushy angiosperm in Kariba Lake area, North-western Zimbabwe, without indication of the plant organ. The local vegetation is the seasonally dry Zambezian open forest and perhaps, more specifically, the Miombo woodland (White 1983). The gross morphology of P. miomboensis, including the small basidiome with narrowly concentrically sulcate pileus, a black line subtending a trichoderm, and small pores reminds much of P. warneckeicola and P. memecyli. These species also share their hyphal system, vegetative hyphae differentiation, and basidiospores shape and size. Phylloporia miomboensis differs in having slightly larger pores (8 – 9 pores / mm vs 10 – 11 and 11 – 13) and different autecological parameters, including the botanical host, the substrate (plant organ), and the habitat. The host of P. miomboensis is unknown. Nonetheless, it is not a species of Warneckea (host of P. warneckeicola) or Memecylon (host of P. memecyli), nor a Melastomataceae; there is no representative of this family in the vegetation at the type locality of P. miomboensis. The habitat of P. warneckeicola and P. memecyli is the humid Lower Guinean rainforest, drastically different from the seasonally dry Zambezian open forest (White 1983, Kindt et al. 2014, Marshall et al. 2021). In a phylogenetic perspective, P. miomboensis is also distantly related from P. warneckeicola and P. memecyli (Fig. 1) and has, hitherto, no known relative in tropical Africa. It is however related to the Australian P. minima, the mediterranean Ph. pectinatus var. jasmini, and an Indian specimen of P. cf. pectinata (Fig. 1).	en	Jerusalem, M., Amalfi, M., Yombiyeni, P., Castillo, G., Decock, C.

9C19878F7050FFEAFF761406FB57B582.taxon	discussion	Notes: Phylloporia pseudoweberiana is characterised by solitary, perennial, deeply sulcate basidiomes (Fig. 12) with a very thin context underneath a comparatively thicker tomentum, both separated by a thin black line. The tomentum wears off with age from the base, exposing then the black line. The hyphal system is dimitic in the context and the hymenophoral trama. The basidiomes emerge from trunk and lower branches (Fig. 12) of the small understory tree Rawsonia lucida (Achariaceae), so far the only known and, a priori, exclusive host. Phylloporia pseudoweberiana is known, hitherto, from the Lake Victoria transitional rainforest (sensu Kindt et al. 2014), at Kakamega Forest National Reserve, in Western Kenya. The Lake Victoria transitional rainforest is the easternmost reminiscence in Kenya of the Equatorial rainforest (Guineo-Congolian rainforest) that stretched from the Atlantic Ocean (Guinea) to the Indian Ocean (Kenya). In a phylogenetic perspective, P. pseudoweberiana is closely related to P. rinoreae, P. cinnamomea, and Phylloporia sp. PY-SN 6 (Fig. 1), currently known from the Western edge of Guineo-Congolian rainforest, in Central and Western Gabon (Jerusalem et al. 2019) and Cameroon. In tropical Africa, P. pseudoweberiana should be compared to P. weberiana sensu Ryvarden & Johansen (1980) or Ryvarden et al. (2022). However, the very identity of P. weberiana and, a fortiori, of P. weberiana sensu Ryvarden & Johansen (1980) or Ryvarden et al. (2022) was uncertain (Caberroi Hernández et al. 2019). Decock et al. (2024) lectotypified and redefined P. weberiana s. s. In that sense, P. weberiana sensu Ryvarden & Johansen (1980) differs from P. weberiana s. s. and P. pseudoweberiana in having much larger pores, mostly 5 – 6 / mm (Ryvarden & Johansen 1980) vs 12 – 13 / mm (Decock et al. 2024) and 9 – 11 / mm, respectively. Phylloporia rinoreae and P. cinnamomea share with P. pseudoweberiana solitary basidiomes, a pileus covered by a broadly sulcate tomentum, comparatively thicker than the underlying context, and both separated by a thin black line, and small pores (> 9 / mm). Phylloporia rinoreae and P. cinnamomea differ in having smaller basidiomes, not exceeding 20 mm wide, 7 mm thick, and larger basidiospores, respectively, mainly 4.0 – 4.5 × 2.5 – 3.0 μm (av. = 4.3 × 2.7 μm) and 3.5 – 4.0 × 2.2 – 2.5 (av. = 3.9 × 2.3 μm). Phylloporia rinoreae also has a distinct substrate affinity and host relationship, growing from narrow, apical twigs of the shrubby Violaceae, Rinorea sp. (Jerusalem et al. 2019). The host tree and substrate of P. cinnamomea are unknown. Out of Africa, P. weberiana sensu Corner (1991) and P. alyxiae (Wu et al. 2020 a) are comparable, in both a morphological and ecological context; both share with P. pseudoweberiana the basidiome habit and anatomy, the tomentum in deeply sulcate, rounded zones, small pores, a dimitic hyphal system, basidiospores similar in shape and size, and some of their autecological parameters (growing from living understorey trees).	en	Jerusalem, M., Amalfi, M., Yombiyeni, P., Castillo, G., Decock, C.

9C19878F7051FFD5FCC714A6FC68B322.taxon	discussion	Notes: Phylloporia warneckeicola is closely related to P. memecyli, whatever the perspective. Both are related also to P. fulva, described from the same phytochorion in Gabon; these species belong to the same well-supported lineage (Fig. 1). They also share most of their biology, including reproduction strategy, morphology, and some of their autecological parameters. They produce perennial, gregarious basidiomes, emerging in dense clusters (Fig. 9), rather small (mostly around 10 mm radius, 1 – 3 mm thick at the base), mostly applanate, densely and very finely concentrically sulcate, shortly velutinous pilei (Fig. 9), and small pores (~ 10 – 13 / mm). Their hyphal system, in the hymenophoral and context trama, could be considered as dimitic, with skeletal hyphae originating from a generative hyphae, occasionally from a mediate hyphae, and of a limited growth (Figs 10, 11), what is especially obvious in the hymenophoral trama. In the classification scheme of Corner (1991), it would be described as dimitic of the fifth degree (d 5). The basidiospores are mostly ellipsoid, ~ 3.2 – 3.5 × 2.2 – 2.5 μm, av. 3.4 × 2.4 µm, ~ 3.5 – 4.0 × 2.2 – 2.5, av. 3.7 × 2.3, and ~ 3.0 – 3.5 × (2.2 –) 2.5 – 2.8 μm, av. 3.2 × 2.7 µm, respectively. They also share the substrate affinities and habitat: they grow from trunks of small-stemmed understory trees, which belong to the Melastomataceae in the case of P. warneckeicola and P. memecyli, and they inhabit the lower Guinean rain forest, at the westernmost edge of the larger Guineo-Congolian phytochorion. Phylloporia warneckeicola and P. memecyli are sympatric at least at the CTFS-ForestGEO Rabi plot in Gabon, an area of the Guineo-Congolian rainforest (Anderson-Teixeira et al. 2014). Phylloporia warneckeicola is abundant at a local scale, depending on the density of its host tree, W. floribunda. In the 25 Ha of the CTFS-ForestGEO Rabi plot, W. floribunda, with a density of ~ 110 individuals / Ha, represents the 14 th most abundant tree (Memiaghe et al. 2016). Most of the individual trees present in an immediate neighbourhood are often hosting P. warneckeicola. Locally, P. memecyli is much less abundant, in parallel to its host tree, Memecylon viride, which is not reported amongst the locally abundant understory tree (Memiaghe et al. 2016). Phylloporia warneckeicola and P. memecyli differ marginally by their pore surface colour, pores size, and basidiospores size; the pores surface in P. warneckeicola has a marked greenish brown tint (brown with greenish hue, bronze on drying), what is best seen in fresh, actively growing basidiomes, whereas it is mostly dark brown in P. memecyli (Fig. 9 C); the pores are, respectively, mostly 11 – 13 vs 10 – 11 pores / mm; the basidiospores are slightly smaller in P. warneckeicola, 3.2 – 3.5 × 2.2 – 2.5 μm, av. 3.4 × 2.4 μm, vs 3.5 – 4.0 × 2.2 – 2.5 μm, av. 3.7 × 2.3 μm. The two species also differ in their host relationships, growing respectively from W. floribunda and M. viride. Phylloporia fulva differs in having a paler pileus colour, greyish orange to pale cinnamon. Its host tree is unknown. Phylloporia miomboensis (cf. discussion under this species) is similar in gross basidiome morphology but differs in having solitary basidiomes, and inhabiting a very distinct ecosystem. It is also phylogenetically distant (Fig. 1). Out of Africa, both P. warneckeicola and P. memecyli should be compared to P. pendula, which is biologically, morphologically, ecologically (Chen et al. 2017), and phylogenetically related (Fig. 1). Phylloporia pendula differs from both African species in having larger pores, 7 – 9 / mm (Chen et al. 2017). Its geographic distribution and, pending confirmation, its host, could also differentiate it. Phylloporia pendula is known so far from Eastern, subtropical to tropical, continental and insular China but its host was not recorded (Chen et al. 2017). The macro- and the micromorphology of the basidiomes of P. warneckeicola and P. memecyli also point toward P. pulla (Yombiyeni et al. 2015) and P. subpulla (Wu et al. 2019). Yombiyeni et al. (2015) redescribed P. pulla based on examination of the type specimen, originating from Indonesia on an unidentified host. Phylloporia pulla is also, in literature (Wu et al. 2019), reported from an unidentified host in Thailand. The species is represented, for the time being, by a single LSU sequence, from the above-mentioned Thai specimen (GenBank accession: MG 738809), but the LSUbased phylogenetic inferences did not allow identifying any close relative (Wu et al. 2019). This species differs from P. warneckeicola and P. memecyli in having broadly ellipsoid to subglobose basidiospores, mostly 2.8 – 3.5 × 2.3 – 2.8 µm (av. 3.0 × 2.6 µm). Phylloporia subpulla was described from tropical, continental and insular China (Wu et al. 2019). It differs from P. warneckeicola and P. memecyli in having smaller pores, 13 – 16 / mm (vs ≤ 13 / mm in both African taxa), and smaller basidiospores, av. 2.7 × 2.0 μm (Wu et al. 2019). Its phylogenetic affinities also are unknown (Fig. 1, Wu et al. 2019).	en	Jerusalem, M., Amalfi, M., Yombiyeni, P., Castillo, G., Decock, C.
