REMARKS

Ryvarden (2004) described T. linteus (as Phellinus linteus) without mentioning a black line in the context. However, Dai & Xu (1998) examined the holotype and indicated the presence of a black line between the context and the superficial tomentum, similar to what was observed in our specimens (Fig. 7). Dai & Xu (1998) also mentioned that the hyphae from context and the trama swell in KOH, but it was not observed in our specimens. It is morphologically very similar to other species of the genus, but differs from other known Brazilian Tropicoporus mostly by the pileate basidiomata, absence of binding-like hyphae in the context and presence of setae.
