The corticioid genus Purpureocorticium was introduced by Wu et al. (2018) to accommodate Purpureocorticium microsporum (Agaricomycetes, Basidiomycota) based on morphological study and phylogenetic analyses of LSU and ef1-α. It was found on an angiosperm branch in mountainous Taiwan. Purpureocorticium is characterized by having a resupinate basidiocarp with smooth hymenial surface, turning purple in KOH, and becomes purplish after storage. The subiculum has a compact texture, nodose-septate generative hyphae, without cystidia, basidia are subclavate with a median constriction, or utriform, and basidiospores are ovate-ellipsoid, smooth and thin-walled, inamyloid and nondextrinoid (Wu et al. 2018). A detailed description for this species was given in Wu et al. (2018).

Type species: Purpureocorticium microsporum S.H. Wu
