DOUBTFUL SPECIES 
Polyporus aegerita Fries, Nov. Symb. 70. 1851. Collected on trunks in Mexico by 
Liebmann. Apparently allied to Fomes geotropus, but smaller. 
Boletus microporus Sw. F). Ind. Occ. 3: 1925. 1806. Collected by Swartz on trunks 
in Jamaica. The description suggests Komes Auberianus or Fomes geotropus, or possibly 
Rigidoporus micromegas. Cortolus sector was called by Schweinitz Polyporus microporus. 
66. FOMITELLA Murrill, Bull. Torrey Club 32: 365. 1905. 
Hymenium sessile, at times semi-resupinate, applanate, epixylous; surface glabrous 
anoderm to encrusted, sulcate with age: context woody or slightly punky, browaieh: 
olivaceous, rarely varying to pallid; tubes minute, cylindrical, usually thick-walled, more 
or less stratose at maturity: spores smooth, hyaline. 
Type species, Boletus supinus Sw.
