Description : MICROPORELLUS Murr.
Bull. Torrey Bot. Cl. 32:483, 1905.

Fruitbodies annual, stipitate, centrally or laterally, stipe often somewhat reduced to a long tapering base. Pileus round, flabelliform to spathulate, rather thin, coriaceous when fresh, rather hard when dry, pileus surface tomentose to smooth, usually distinctly zonate, ochraceous to bay, pores small, context white to ochraceous. Hyphal system dimitic, generative hyphae with or without clamps, skeletal hyphae present in trama, absent or present in the context, cystidia none. Spores globose to subglobose, hyaline, smooth, thin-walled and non-amyloid. On deciduous wood. Pantropical genus.
Type species: Microporellus dealbatus (Berk. & Curt.) Murr.
Literature: Reid. D.A., 1975: Notes on Polypores (Bracket Fungi). Microscopy 32: 452-53.
REMARKS. The genus resembles Microporus, but does not have any binding hyphae nor the typical coralloid organs covering the dissepiments in Microporus. The spore-form in general is also different. Favolus has fruitbodies of the same form, but has much larger pores and spores, and the generative hyphae have simple septa besides the vegetative hyphaee being of a different kind. Young specimens of Trichaptum biformis may superficially remind of Microporellus, but Trichaptum is easily recognized because of its apically encrusted cystidia.
