Maybe we should try a new name in order to be able to….

do a better job of defining mushrooms in the lavendula and porphyria orbit. Amanita series Mappae would include brunnescens which is too broad a grouping; however, Amanita stirps Bulbosa would include just the citrina-like and porphyria-like taxa of the world. In eastern North America this is a relatively cozy little group (so far as we know) including porphyria, lavendula-like species, and solaniolens-like species, and maybe some stuff we don’t understand very well or don’t know about at all.

So I’m going to propose the name at the stirps level. Names at this rank do not have authors. These names are a convenient way of forming small groupings for taxonomic work. Bas used them to good avail in section Lepidella. They are used (still somewhat sparingly) on the WAO website.

Very best,


Thank you

A graying partial veil is also seen rather commonly in specimens of the “lavendula” group in eastern North America; given the pileus color in the present observation, I think it is more likely that you have something in the latter group of species than porphyria.

Very best,
