Don’t blame me. Blame the field guide. :-)

Looks like you meant image 11362, rather than observation 11362.

11362 is the rugulose Cystoderma.

You have the right species, but the wrong variety. Both are very cool.

11362 is a bolete.

I rechecked my field guide, and it definitely has a mushroom resembling what I saw, without the prominent folds you mentioned, as var. rugosoreticulatum.

see sighting 11362 for a photo of a rugulose amianthinum.

Smooth? Smooth?! The cap is very clearly covered in fine warty bumps … but it is not wrinkled. :-)

Shouldn’t it be “amianthinum”, with an h, by the way?
