Zhao, M. Wang & Y. C. Zhao	<div><p>Helvella sublactea Q. Zhao, M. Wang &amp; Y.C. Zhao (FIGURE 2)</p><p>Description:—Apothecia irregularly lobed or saddle-shaped, 10–30 mm high, 20–40 mm broad, edges fused with stipe; hymenium smooth without hairs, creamy to greyish brown when fresh, brownish when dried; receptacle surface without hairs, whitish when fresh, light grey when dried (FIGURE 2A). Stipe 20–40 mm long, 5–20 mm broad, expands to upwards and fuses with edges of pileus, cream to light greyish, becoming creamy when dried, covered in fine hairs, with deep longitudinal ribs, few anastomoses between furrows, with white mycelium at the base (FIGURE 2A). Ectal excipulum 60–70 μm broad, of textura angularis, hyaline. Medullary excipulum 220–300 μm broad, of textura intricata, hyaline, formed 3–4 μm broad hyphae. Asci 250–300 × 13–20 μm, 8-spored, uniseriate, pleurorhynchous base, subcylindrical to clavate (Figs 2B, E, G). Paraphyses 2–4 μm broad, septate, rarely branched, filiform, slightly exceeding the asci, with a yellow refractive content in Melzer’s reagent, apices spear-like and irregularly enlarged to 5–10 μm broad (Figs 2E, F). Ascospores (14) 15–17 (19) × 10–13.5 μm, Q = (1.3) 1.4–1.6 (1.7), ellipsoid, hyaline, smooth-wall and uniguttulate (Figs 2C, D).</p><p>Specimens examined: — Türkiye, Erzurum-Kars province Sarıkamış district, under conifer trees, 40°26’32”N 42°29’56”E, 2427m 20.05.2021, MEA 141, VANF 7892.</p><p>Habitat and distribution: —Solitary or gregarious on the soil under Castanea spp. or Quercus spp. trees. Only known from high altitude localities in southwestern China (Wang et al. 2016).</p><p>Notes: — Helvella sublactea is morphologically and phylogenetically close to H. fuscolacunosa and H. ravida . Helvella sublactea has creamy to greyish brown hymenium and broader paraphyse apices, whereas H. fuscolacunosa has grey-brown to almost black hymenium and also differs with cylindrical and narrower (up to 17 µm) asci (Skrede et al. 2020). Helvella ravida has a white hymenium without any brownish tint and narrower paraphyse apices.Additionally characterized by wider paraphyses (measuring 8–13 µm at the tips) and longer asci (reaching up to 340 µm) (Wang et al. 2023).</p><p>Phylogenetic analyses using multi and single-locus data indicated that H. sublactea shares a close evolutionary relationship with H.fuscolacunosa and H. ravida (FIGURE1 and Figs S1–S 3).These species share similar characteristics, such as connivant saddle-shaped or irregularly lobed pileus, whitish hymenium, a white surface on the receptacle, and white ribbed stipes, though they can be distinguished by certain features as mention above. Molecularly, H. sublactea is distinguished by 116 substitutions from H. fuscolacunosa (92 in ITS and 24 in LSU) and 103 substitutions from H. ravida (79 in ITS, 17 in LSU, and 7 in TEF 1-α).</p></div>	https://treatment.plazi.org/id/A572961D7A38FFBFFF414A32FD3EFD34	Public Domain	No known copyright restrictions apply.

Stipe 2–15 mm long, 1–5 mm broad, solid, slightly curled cylindrical sometimes expands towards the pileus, conspicuously pubescent, whitish to cream or pale grey (FIGURE 3A). Ectal excipulum 190–230 µm thick, of textura angularis or textura prismatica, outer cells cylindrical or clavate, hyaline. Medullary excipulum 320–350 µm thick, of textura intricata, hyphae 3–4 µm thick, septate and branched, hyaline. Asci 300–360 × 16–24 μm, 8-spored, uniseriate, cylindrical, tapers towards the base, almost all pleurorhynchus (Figs 3B, C, D). Paraphyses filiform, septate, somewhat branched, 3–4 µm thick, thickened at the tip to 5–10 µm, slightly exceeding the asci (Figs 3B, C).

However, these species can be distinguished by several features. Helvella multiformis has lighter-colored caps and shorter, thinner ascospores, with a maximum length of 20 µm and a width of 13 µm, resulting in smaller asci (Mao et al. 2023). Helvella sublicia can be distinguished by its near-white to greyish hymenium surface, sub-pubescent to villose receptacle, and narrower ellipsoid ascospores (Skrede et al. 2017, 2020). Molecular data, including combined and three single-locus datasets, further supports the separation of H. rivularis from its close relatives (FIGURE 1 and S1-S 3). In the aligned concatenated dataset, 98 nucleotide differences were identified between H. rivularis and H. multiformis (ITS: 63, LSU: 17, TEF 1-α: 18), and 98 variations between H. rivularis and H. sublicia (ITS: 60, LSU: 18, TEF 1-α: 20).</p></div>	https://treatment.plazi.org/id/A572961D7A3EFFBCFF414E14FEDEFC15	Public Domain	No known copyright restrictions apply.

Stipe poorly to moderately differentiated, 3–5 mm long, 5–10 mm broad, solid or with few chambers, evidently ribbed, with ribs that may have sharp or blunt edges and minimal branching or merging, ochre when fresh, cream to white when dry, with less prominence, somewhat tapered to base, surface pubescent or finely pubescent (Figs 4A, B). Ectal excipulum brownish, pigment deposits in the cell wall and cytoplasm. Medullary excipulum hyaline. Asci 210–300 × 14–19 μm, pleurorhynchous base, 8-spored, uniseriate, subcylindrical to clavate. Paraphyses filiform, septate, somewhat branched, 2–4 μm broad, slightly exceeding the asci, content pale brown to medium brown, ± homogeneous, apex apparently enlarged, 4–7 μm broad, weakly to moderately cyanophilic (Figs 4F, G, H). Ascospores (16)17–21 (22) × 11–13.5 μm, Q = (1.4) 1.5–1.7 (1.8), broadly ellipsoidal, hyaline, smooth-wall and uniguttulate (Figs 4C, D, E).</p><p>Specimens examined: — Türkiye, Erzurum-Kars province, Sarıkamış district, under conifer trees, 40°16’20”N 42°27’30”E 2373 m, 07.06.2021, ME 127, VANF 7893.</p><p>Habitat and distribution: —In the subalpine to alpine zones of high-altitude countries such as Sweden and Norway, it often grows in groups among herbaceous plants such as Dryas and Braya spp. (Harmaja 1977, Skrede et al. 2017).</p><p>Notes: — Harmaja (1977) described Helvella arcto-alpina based on detailed analyses of H. acteabulum collections and provided a morphological, anatomical and ecological comparison of the two species. According to Harmaja, the concept of H. acetabulum is a large, pale, early southern species, while H. arcto-alpina is characterized as a small, dark, late arctic-alpine species. The caps of H. acetabulum can reach up to 8 (12) cm in diameter, whereas the cap of H. arcto-alpina is up to 2 cm in diameter. The collection of specimens from the Erzurum-Kars region, the highest altitude area in Eastern Anatolia of Türkiye and close to the alpine zone boundary, supports our identification as H. arcto-alpina . Skrede (2017) further established that H. arcto-alpina is phylogenetically distinct from H. acetabulum based on several nucleotide variations in the TEF 1-α and LSU sequences. In the current study, similar results were observed; with H. arcto-alpina and H. acetabulum consistently grouped together in all generated phylogenetic trees (FIGURES 1 and S1–S 3) but discriminated from each other by 25 variations in ITS, 30 in LSU and 19 in TEF 1-α data.</p></div>	https://treatment.plazi.org/id/A572961D7A3DFFBDFF414934FAA3FF3D	Public Domain	No known copyright restrictions apply.
