Yeah, the photos are very unclear, that is why I posted the link to the photos on Google image search for the observer to compare.

You got a problem with LBM’s?!!?

Melanoleuca verrucipes

This is probably a species introduced from Europe.

I spent hours trying to ID them last year. Everyone at the MSSF meet was stumped (in fact some argued that they were most likely brown spored- but the spore print came out pale cream/white). I ended up bringing some fresh specimens to SFSU to have the resident Mycologist and Scientific Advisor for the MSSF, Dennis Desjardin, take a look at them. He didn’t have a clue until he looked at them under the microscope and was then certain they were Melanoleuca.

I suggested we search google images for “melanoleuca” to try and find a photo that looks similar and be able to ID it to species. After pages and pages of scrolling, we finally ran across a photo of Melanoleuca verrucipes, and it matched perfectly with my collection.
A SOMA member found this same species not too long ago (within the last 3 yrs, I believe) and ran into the same ID troubles.
