DOUBTFUL SPECIES 
Favolus velutipes Fries, Nov. Symb. 104. 1851. Ocrsted’s outline drawing and notes 
which formed the basis of Fries’ description are still to be seen at Copenhagen, but these 
are hardly sufficient to distinguish the species properly from its numerous congeners. 
36. MICROPORELLUS Murrill, Bull. Torrey Club 32: 483. 1905. 
Hymenophore thin, annual, epixylous, usually flabelliform, stipitate, the stipe variously 
attached and sometimes much reduced; surface anoderm, multizonate: context thin, white, 
fibrous, rigid and fragile when dry; tubes very minute, regular, thin-walled, fragile when 
dry: spores smooth, hyaline. 
Type species, Polyporus dealbatus Berk. & Curt.
