     Cortinarius pyriodorus

Cortinarius husseyiKey to Gilled Mushrooms     Key
This is a key to gilled mushrooms, that is, mushrooms having a definite cap with a fertile surface consisting of gills. The fruiting body usually also has a stem, although that may be lateral or absent (usually, then, the mushroom is growing from wood). You can use this key to identify mushrooms that you find.

Cortinarius traganus


Microscropic Characters


Well, I was all set to do a nice big section of Sericeocybe called MottledFleshSericeocybe, but after considerable soul-searching, I have decided to synonymize all its other species with Cortinarius traganus
As far as I can tell from the literature I have, these differ only in odor and subtle shades of flesh color. Spore sizes are the same (or well, well, well within the range of error of different collections and moving between different instruments); the external colors are the same; the size and proportions of the fruiting bodies are the same; call me a lumper, but I just don't see the difference. The shades of flesh color can easily be accounted for by moisture or other environmental conditions (trace elements), and if differences in odor alone justified distinguishing species, we'd also have five different species of Russula laurocerasi
Perhaps someone will come up with a clear way to distinguish these taxa; until then I see to reason to bust my head by trying to perceive and evaluate these "differences", nor, by pretending to distinguish them, to direct you to bust yours
