Vlasenko 2025	<div><p>Hemitrichia schnittleri A. Vlasenko, sp. nov. Figs 1, 2</p><p>MycoBank no: 860582</p><p>Etymology:— The specific epithet honours Martin Schnittler, a renowned myxomycetologist who studied the myxomycetes of Mongolia.</p><p>Sporocarps densely clustered or closely appressed, globose to cylindrical, 0.3–0.8 mm in diameter, up to 0.8 mm in height, yellow with an iridescent sheen; borne on a narrowed base or short filamentous stalks that are continuations of the peridium, with stalks sometimes appearing as extensions of the hypothallus. Hypothallus is membranous, thin, pale, and continuous under the entire colony. Peridium single-layered, thin, with an iridescent sheen; inner surface is covered with warts (in SEM). Dehiscence is irregular; in the upper part of the sporangium the peridium breaks into fragments of varying size, and thus the base remains in the form of a calyculus. Capillitium formed of very long threads, occasionally branched, 3.5–5 µm in diameter, ornamented with two weakly developed spiral thickenings; the thickenings with spines and warts (in SEM). Spores are yellow in mass, pale yellow in TL, globose, 10–13 µm in diameter. Spores form clusters of varying size; after the clusters disintegrate, each spore has a zone of attachment to the cluster in the form of outgrowths on the peridium. Plasmodium not seen.</p><p>Holotype:— MONGOLIA.

Lister (1911: 227) . The main morphological differences between these two species lie in the ornamentation of spores and threads of capillitium. Hemitrichia schnittleri has spores clustered into complexes; when these complexes disintegrate, individual spores consistently exhibit projections on one side (in TL) that facilitate their aggregation into groups. This feature is completely absent in H. abietina, whose spores are always free. The spiral thickenings on the threads of capillitium of H. schnittleri are covered with spines and warts (in SEM), whereas those of H. abietina are smooth.</p><p>The ML analysis based on the 18S nrDNA region (Fig. 4) showed that H. schnittleri is an independent species, closest to H. abietina . The genetic distance of the H. schnittleri branch on the SSU tree is 0.044, with 97% bootstrap support.</p></div>	https://treatment.plazi.org/id/03AC87F6FF9D8711FF3AFEABFF56B864	Public Domain	No known copyright restrictions apply.

Stalk thick, dark brown to black, reaching almost half the height of the sporangia. Hypothallus dense, well-developed, shiny, ochre-brown, common to the colony or group of sporangia.

Elaters olive-yellow in mass, dark yellow in transmitted light, rarely branched, cylindrical, of varying length 20–200 µm, 2.8–4 µm in diameter, usually with four well-arranged smooth spiral thickenings, ending in thin tips up to 15 µm length.
