There was another of these Pluteus that had fruited just before a rainfall of 6-10 cm. This lone mushroom was well rotted. But at least it pointed me toward the exact dead tree where the original collection was made (182725).

Mushrooms in the this obs found at the base of a well rotted dead tree… most likely aspen (poplar) or possibly yellow birch.

Thanks GALL.

The spores seen in the Wikipedia link look exactly like the ones I observed with this collection. Length and width are also a good match.

I accidentally deleted my spore photo before loading onto my computer.

Near the base of a tree…

but at ground level. I should have noted the tree type, but did not.

thanks Dave

do you remember if this was growing attached to wood remnants or on the ground?

Thanks Fredo.

I’ll reserve one specimen for you. I’d like also to send one to the New Jersey Mycological Association to be deposited into their herbarium. The material appears to be in excellent shape. It was in the dehydrator only a few hours after being collected.

Our local club will have a foray at this site on Sunday. Maybe someone will run across another collection. The old growth forest in this park in never cleared of downed trees, as a means of preserving its natural character. Lots of interesting saprobes!

very likely in the ephebeus group

this is a very diverse species complex both in Europe (at least 3 species) and North America (at least 3 temperate species plus some tropical taxa).

how are we going to match up genes, available names and morphologies is still an open question
