Europe (Czech Republic, France, Italy), on herbaceous remnants, once collected from pine bark at the same spot where it was found on fern remains.</p><p>Remarks.</p><p>Eriksson and Ryvarden (1976) selected Bourdot 7226 (in herb. S) as lectotype. They also treated Hyphodontia nikolajevae and Odontia pruinosa as synonyms. However, the type specimens of H. nikolajevae and O. pruinosa reveal small differences from the type material and other collections of X. detriticus studied by us. The main features of X. detriticus versus the two other taxa are narrower basidiospores (must be observed in cotton blue) and longer, narrower cystidia having no distinct intercalary inflation (Tables 2, 3, Figures 5, 6). Eriksson and Ryvarden (1976) attributed the differences in cystidia morphology between Bourdot’s specimen and types of H. nikolajevae and O. pruinosa to different stages of basidiocarp development. Our investigation indicates that the differences are genetic and species specific. Differences in basidiospore size and shape are detectable in CB but not in KOH, which could explain why they have gone unnoticed in earlier studies.</p><p>Hjortstam and Ryvarden (2009) added Hyphodontia magnacystidiata to the synonymy of X. detriticus . This species is, as far as we know, only known from the type, collected on dead wood of Populus in New York, USA (Lindsey and Gilbertson 1977). It has an odontioid basidiocarp and its cystidia are similar to those of X. pruinosus (Table 3, Figures 6, 8). On the other hand, the basidiospore size is very close to X. detriticus (Table 2). In the absence of sequenced material, it is not possible to decide whether this is an independent species or not. Considering that the single specimen was growing on wood and that X. detriticus is not yet found in North America, we prefer to keep H. magnacystidiata as a synonym of X. pruinosus (see below).</p><p>Xylodon detriticus grows on ferns and grasses, developing thin farinaceous basidiocarps. The species evidently has a more southern distribution than X. pruinosus . Earlier reports of X. detriticus from woody substrates should be treated with caution and may represent X. pruinosus or as yet undescribed taxa.</p></div>	https://treatment.plazi.org/id/3E1F87DEE9048811BD00D28C7C912837	Public Domain	No known copyright restrictions apply.

Our specimens collected in the Russian Far East fit well with his description. One of these collections (Spirin 5763) was sequenced and proved to be close to other sequences of H. nongravis available in GenBank. The species undoubtedly belongs to the core Xylodon clade (Figure 1) where it has been combined by Chen et al. (2018). However, the type specimen of Polyporus nongravis possesses small but clear morphological differences from our collections: in particular, wider pores (2-3 per mm in the type, 3-4 per mm in East Asian specimens) and broader tramal hyphae (4-6 μm vs. 3-4.5 μm in diam.), as well as broader, predominantly subglobose basidiospores, 3.9 –4.7×3.6– 4.2 μm (n=30/1), L=4.27, W=3.97, Q=1.08 (vs ovoid-ellipsoid, 4.0 –5.2×3.0– 4.1 μm (n=60/2), L=4.74, W=3.46, Q=1.38 in East Asian specimens). An epitype for P. nongravis from the locus classicus is needed to re-introduce this species based on modern methods and to clarify the taxonomic status of X. nongravis sensu East Asia.</p></div>	https://treatment.plazi.org/id/45D1D7B22FE2B1D36AC260EAD43CAF77	Public Domain	No known copyright restrictions apply.

Figure 12</p><p>Type .</p><p>RUSSIA. Primorie: Khasan Dist., Kedrovaya Pad Nat. Res., on angiosperm wood, 24 Jul 2016, I.Viner KUN 1989* (H) - ITS sequence, GenBank MH324468.</p><p>Etymology.</p><p>Ussuriensis (lat., adj.) - from the river Ussuri in Russian Far East and adjacent China.</p><p>Description.</p><p>Basidiocarps effused, up to 10 cm in longest dimension. Sterile margin white to pale ochraceous, floccose, up to 1 mm wide. Hymenial surface pale ochraceous, grandinioid to odontoid; projections rather regularly arranged, from 100 µm to 250 μm high, 90-110 μm broad at base, 6 –8(– 9) per mm. Hyphal structure monomitic, hyphae clamped, faintly cyanophilous, thin-walled. Subicular hyphae interwoven, (3.0 –)3.4– 6.2 μm in diam. (n=30/3). Tramal hyphae subparallel, sub hymenial hyphae short-celled, 1.9-3.9 μm in diam. (n=30/3). Large rhomboid or stellate crystals rarely present in trama and subiculum, 10-19 μm in diam. Cystidia of three types: a) large, thin- or fairly thick-walled (wall up to 2.8 μm thick) cystidia of subicular, tramal or subhymenial origin, cylindrical, spathuliform, almost capitate or with one intercalary inflation at the upper part, (64.0 –)71.0–188.9(–220.0)×(5.0–)5.7–9.4(– 11.9) μm (n=30/3), often apically encrusted by large rhomboid crystals, b) astrocystidia of subhymenial origin, bearing a stellate crystalline cap 15 –17×4.5– 4.8 μm, sometimes rare, c) cystidia of subhymenial origin, thin-walled, varying from fusoid to cylindrical or submoniliform, rarely forked, 40.0 –84.0(–92.0)×5.0–9.0(– 11.4) μm (n=30/3). Basidia suburniform, 4-spored, 14.7 –22.8(–24.0)×3.4– 4.9 μm (n=30/3), thin-walled . Basidiospores clearly thick-walled, ellipsoid to broadly ellipsoid, usually with an oil-drop, (4.8 –)5.1–6.0×3.8– 4.6 μm (n=92/3), L=5.48, W=4.21, Q=1.30, cyanophilous.</p><p>Distribution and ecology.</p><p>East Asia (Russian Far East - Primorie), on decayed angiosperm wood; seemingly not rare in secondary oak-dominated forest.</p><p>Remarks.</p><p>The distinctly thick-walled tubular cystidia of X. ussuriensis make it different from other Lagarobasidium -like species treated here. Subhymenial astrocystidia found in X. ussuriensis are also present in some specimens of X. detriticus although they are apparently rare in the latter species.</p></div>	https://treatment.plazi.org/id/7A3E78A42BA3576D1EE4BAD8208DD3DB	Public Domain	No known copyright restrictions apply.
