In the present study, four new wood-inhabiting fungal species, <i>Adustochaetealbomarginata</i>, <i>Ad.punctata</i>, <i>Alloexidiopsisgrandinea</i> and <i>Al.xantha</i> collected from southern China, are proposed, based on a combination of morphological features and molecular evidence. <i>Adustochaetealbomarginata</i> is characterised by resupinate basidiomata with cream to buff, a smooth, cracked, hymenial surface, a monomitic hyphal system with clamped generative hyphae and subcylindrical to allantoid basidiospores (12-17.5 × 6.5-9 µm). <i>Adustochaetepunctata</i> is characterised by resupinate basidiomata with cream, a smooth, punctate hymenial surface, a monomitic hyphal system with clamped generative hyphae and subcylindrical to allantoid basidiospores (13.5-18 × 6-8.2 µm). <i>Alloexidiopsisgrandinea</i> is characterised by resupinate basidiomata with buff to slightly yellowish, a grandinioid hymenial surface, a monomitic hyphal system with clamped generative hyphae and allantoid basidiospores (10-12.3 × 5-5.8 µm).
