The four species of Byssocorticium can be readily distinguished from Leptosporomyces caeruleogriseum by their larger basidia and differently shaped basidiospores. Byssocorticium atrovirens possesses basidia measuring 15–25 × 4–5 µm and subglobose basidiospores (Bernicchia et al. 2010); B. caeruleum has basidia 22–30 × 6–7 µm and globose, subglobose, to pyriform basidiospores (Kotiranta et al. 2012); B. pulchrum is characterized by basidia 25–30 × 6–7 µm and globose basidiospores (Eriksson and Ryvarden 1973); and B. yunnanense has basidia 16.5–32 × 5–7.5 µm and globose to ellipsoid basidiospores (Wijesinghe et al. 2025). In contrast, L. caeruleogriseum has much smaller basidia (8.5–12 × 3.4–4.5 µm) and oblong ellipsoid basidiospores.</p><p>Morphologically, L. caeruleogriseum is highly similar to L. galzinii by having resupinate and smooth basidiomata, similar hyphal structure, and similar basidiospores (Eriksson and Ryvarden 1976). However, L. galzinii has detachable basidiomata with a glaucous surface and has a distribution in Europe (Eriksson and Ryvarden 1976), whereas our new species has fully effused basidiomata with a bluish gray surface and occurs in Asia.</p></div>	https://treatment.plazi.org/id/19EDFA4D1B3D54C2917874C9BCDD56F2	Public Domain	No known copyright restrictions apply.
