Microporellus dealbatus* (Berk. & M.A. Curtis) Murrill, Bull. Torrey bot. Club 32(9):483 (1905)

Remarks: This species is characterized by the laterally to centrally stipitate basidiomes, which are hard when dried. Small pores (8-10 per mm) and drop-shaped basidiospores (4.5-6 x 3.5-4.5 µm) differentiate M. dealbatus from other Microporellus species ( Motato-Vásquez & Gugliotta 2016).
