Abundisporus

Abundisporus Ryvarden 1999, in Cui, et al., Fungal Diversity 97, 137–392 (2019)

Basidiocarps perennial, pileate or effused-reflexed to resupinate. Pilei cinnamon pink to brownish or blackish brown. Pore surface white, pinkish to buff or pinkish brown; pores round to angular; dissepiments thin, entire. Context pale umber to deep purplish brown or grayish to umber brown. Hyphal system dimitic; generative hyphae bearing clamp connections; skeletal hyphae yellow to pale brown, usually dextrinoid, CB+. Basidiospores ellipsoid, pale yellowish, slightly thick-walled, smooth, IKI–, CB+.

Abundisporus was established by Ryvarden (1998). Morphologically, it is similar to Perenniporia Murrill, but separated mainly by its pinkish basidiocarps and colored basidiospores. Current species of Abundisporus were initially treated under Loweporus Wright (Corner 1989; Ryvarden 1991, 1998). Ryvarden (1998) concluded that A. fuscopurpureus, A. roseoalbus (Jungh.) Ryvarden and A. violaceus (Wakef.) Ryvarden formed a morphologically homogeneous alliance, and then accommodated them to a separate genus Abundisporus. Molecular phylogenetic analysis supported that Abundisporus sensu Ryvarden is monophyletic and suggested the genus as a clade distinct from the Perenniporia sensu stricto clade (Robledo et al. 2009; Zhao et al. 2013, 2015).Most species of Abundisporus were recorded in tropical and subtropical areas (Ryvarden 1998), but A. pubertatis (Lloyd) Parmasto and A. quercicola Y.C. Dai werereported from temperate areas (Dai 2012).
