Recognized by sight: ID’d by Gaston Guzman, who said “Your Omphalotus from Michoacan (Mexico) seems O. mexicanus Guzman & Mora, a specie that I described in 1983 (see Boletin Sociedad Mexicana de Micologia 18: 115-139). It is a pity which you do not have herbarium specimens. To check the determination it is necessary to study the microscopy. Thank you for to informed me about that special mushroom, which is more or less common in Mexico, but difficult to find.”

I saw the name and thought it might fit. Any idea what these could be? I have been calling it a black Omphalotus. It was conspicuously missing from the fungus fair this year, I will be looking for these next August.

Colors don’t fit

According to the original article in Mycotaxon (48: 217-222) the color of Omphalotus olivascens var. indigo is “orange-ochre with typical olivaceous tints”. Gills “yellow-olivaceous, becoming orange near the edge”. Stipe “concolorous”. FLESH “yellow-olivaceous turning immediately blue-grayish”. The photos presented here show numerous lacerations in the cap revealing WHITE flesh and the cap, gills and stipe are all blueish-gray.

Looks like Omphalotus nidiformis, but Wikipedia and other sources suggest that species is confined to Australia.

Perhaps it has spread, or they were wrong, though. Or perhaps this is not an Omphalotus.
