This material is accessioned.

Very best,

I didn’t “already know.” :) Actually, I was using some visual cues to create a hypothesis. Certainty isn’t achievable.


I agree, Stephen. The spores are very small for a Lepidella.

Lepidella is still a possibility, but I think the Validae should be considered. One trick with the Validae is that they have rather small basidia also, always lack clamps, and almost always have a subhymenium that is clearly and distinctively composed of small inflated cells (what folks call a “cellular” or pseudoparenchymatic subhymenium).

I thought of A. salmonescens, but the spores are bigger in that species.

This might be something new…

Very best,


No idea

Spores seem way too small for most lepidellas.

Just pulled another sample and they are fitting in that range….

The spore data…

proves RET right, but he already knew that. :-) Any ideas as to what this lepidella might be?

Updated with spore data.

I think that the partial veil is too weakly structured for cokeri

or subcokeri. Also, they usually have pyramidal warts.

I think that the size and shape of the spores may help.
