or Dennis goofed/skimped on important details, and INBio had access to a better description which actually fits both of these. after all, the discrepancies in Dennis’ description are more in terms of features which he doesn’t describe at all as opposed to ones which are in conflict with features we’re seeing here.

is that INBIO misinterpreted the name early on, but attached it to a good quality photo and thus propagated a naming error (ie. a wrong name for a recognizable thing)

I’ll concede that these

may be the same species, but Dennis’ description of M. rhyssophyllus (see name page) neglects to mention basal strands/tomentum, the uneven margin, striations, eccentric attachmnent, pleurotoid habit, and calls the gills “rather crowded.” these micrographs also show no inflated terminal cells in the pileus, nor “thin-walled, irregular, vesicular hairs about 40 × 15µ” along the gill edge. would be helpful to compare these to another, newer description.
