Crassiparies (Li et al. 2016; Tanaka et al. 2017), Medicopsis (Devadatha et al. 2020), Muriformispora (de Silva et al. 2022; Wu et al. 2024), Neomedicopsis (Hyde et al. 2018; Crous et al. 2019), and Splanchospora (this study) are known to have both sexual and asexual morphs. On the other hand, Brevicollum (Tanaka et al. 2017) and Neobrevicollum (Lu et al. 2024) are known only from their sexual morphs, whereas Neohendersonia (Giraldo et al. 2017) and ‘ Amarenographium ’ solium (Hodhod et al. 2012) are known only from their asexual morphs. In this study, we show that the presence of paraphyses in the conidiomata of Splanchospora expands the morphological concept of the asexual stage in Neohendersoniaceae .</p></div>	https://treatment.plazi.org/id/BC95C543D81A55C2BE14EF05EEACA462	Public Domain	No known copyright restrictions apply.

The location of the type specimen of Sphaeria ampullacea is unknown, and the original description of the species did not provide information on the ascospores (Persoon 1801). The only extant collection of Sphaeria ampullacea in the Persoon herbarium (L 0112460) cannot represent the type, because this collection was evidently collected after its description (Persoon 1801), as brought forward in a detailed note by R. A. Shoemaker attached to this specimen (see https://bioportal.naturalis.nl/nl/multimedia/L0112460). To stabilize the species concept, we therefore here designate collection WU -MYC 0057753, for which detailed morphological data as well as sequences are available, as the neotype for Sphaeria ampullacea Persoon. Shoemaker and LeClair (1975) designated the neotype specimen of Massaria curreyi, which is a heterotypic synonym of Sphaeria ampullacea, and examined its ascospores. Although the ascospores from our specimens (30–45 × 13–18 μm) are broader than those from the neotype of Massaria curreyi (36–42 × 13–14.5 μm; Shoemaker and LeClair 1975), the values partially overlap. In our specimens, pycnidia with 1 - celled conidia are closely associated with the species. Although the strains examined in this study were sterile in culture, we recognised the pycnidia on the natural specimens as being asexual morphs on the basis of their similarity to those of other Splanchospora spp.</p></div>	https://treatment.plazi.org/id/6EF5D60F95CB568F8092BD1A2F2006B1	Public Domain	No known copyright restrictions apply.

Splanchospora is similar to the genera with sexual morphs in having immersed ascomata with a central ostiolar neck, except for Brevicollum, which has an excentric to ostiolar neck (Tanaka et al. 2017). However, Splanchospora differs from Crassiparies, Medicopsis, Muriformispora, Neobrevicollum, and Neomedicopsis in having clavate-ellipsoid, thick-walled ascospores strongly constricted at the submedian septum. Amongst the members of Neohendersoniaceae with asexual morphs, Neohendersonia and Neomedicopsis are more similar to Splanchospora in having annellidic conidiogenous cells (those of Neomedicopsis were described as ‘ proliferating percurrently’ and illustrated in fig. 34 B in Crous et al. 2019) and thick-walled conidia. Notably, Neomedicopsis shares long conidiogenous cells and aseptate conidia with Splanchospora and is sister to the latter genus. However, Splanchospora is distinguished from Neohendersonia and Neomedicopsis by the presence of paraphyses in the conidiomata.</p></div>	https://treatment.plazi.org/id/BF552B1D3B7E50B6937F1D066A97827C	Public Domain	No known copyright restrictions apply.

These two species differ in various sequences: namely, at four sites with one gap in the ITS (99.1 % homology = 448 / 452), at 27 sites with a single amino acid substitution in RPB 2 (97.5 % = 1,038 / 1,065), and at 24 sites with four gaps and a single amino acid substitution in TEF 1 (98.0 % = 1,206 / 1,230).</p><p>The ascospores size [27.5–37 (– 45.5) × 9.5–16 (– 20) μm (n = 176)] of S. pseudomicrospora is highly variable. This is probably due to occasional meiotic failure or stunted spores, resulting in enlargement of the remaining ascospores in the ascus. The size of ascospores from 8 - spored asci are 27.5–37 × 11–15.5 μm (n = 54), whereas those from 4 - spored asci are 38–40 × 17.5–20 μm (n = 4). This variability makes the identification of Splanchospora species on the basis of the ascospores alone more difficult.</p></div>	https://treatment.plazi.org/id/DF4E4780B9B95052B4786205CE7B279E	Public Domain	No known copyright restrictions apply.
