Species Information
Summary:
Features include 1) resupinate growth on wood, 2) a fruitbody that is arachnoid to hypochnoid, colored cream to pale buff, 3) spores measuring 7-10 x 2.5-5 microns that are navicular to elliptic with a prominent apiculus, smooth, inamyloid, and colorless, 4) 4-8-spored basidia, and 5) wide subicular hyphae with right angle branching and without clamp connections. Note that Corticium vagum (Berk. & Curt.) sensu Burt is a synonym of Rhizoctonia solani.
