All of these morphologically identical Pholiota species might actually be biologically heterogenous, despite possessing radically different microscopic structures. To the best of my knowledge (which is quite limited), Aside from Monclavo’s very broad study, no molecular data has been amassed for the genus Pholiota.

The problem I have with mating and molecular studies is that the data is only as accurate as the individual who labeled the specimen. When I read something that says “Pholiotas matching the physical descriptions of Pholiota limonella…” it makes me wonder if macro-morphology is all that Farr relied on to identify his collections of P. squarrosa-adiposa, or worse yet, herbarium labels.

I think that the prevailing divergent morphology in this observation (the extremely dark, immature pilei) merits further investigation before assigning a species level taxon. However, I completely understand why one would prefer to simply call it P. limonella. At what point does it truly matter how different the infant morphology is, or how big the cystidia are, when it looks exactly the same as four other species and decomposes the same strata as four other species…

I imagine a reengineering of Pholiota based on molecular data would be prohibitively exhausting.

I personally call all these pholiotas P.limonella

because as an amateur I just don’t know better :-)
Here is article from Kuo dwelling on species you mention here, including but not limited to: P.limonella, P.squarroso-adiposa, P.aurivella:

Coating the immature pilei seem consistent with Smith’s concept of P.squarrosa-adiposa, but the stipe decoration does not.

interesting observation!

Run across this species again, I’d love a couple specimens.mi think all of the mushrooms photographed are the same species.

I only got an adult specimen for a spore print (dark brown)

But babies can be from other species. The two life stages were intermixed on the log, with groups of mature ones alternating, somewhat, with young ones.

Very interesting

The mature specimens look like P. aurivella, but the immature specimens are much, much darker than I have ever seen in that species. Any chance you dried some?

I was just picking everybody’s brain :-)

by uploading babies first, before I revealed the entire gang.
