Excellent.

Let’s sequence it. Material from Mexico is precious cause it bridges the gap between California and the rest, as well as the entire North America — during the ice ages it was Mexico that became the oasis of species.

I knew it was a good one so I picked 20 fruit bodies of various stages of development with the intent of making a type collection. I just added a couple spore pictures.

There are very few Fagus forests in Mexico, and many of the mushrooms there are undescribed.

It is Telamonia s.s.

That’s beyond the shadow of a doubt.

Alan, if you save the collection I’ll get some genes out of it. This is a good one.

KOH was mixed in the field

So I do not know the strength, but I always mix it on the strong side. It was probably very dark brown at first, but was basically black by the time I photographed it, even when I overexposed the picture.

I also added spore information.

Is it definitely in subgenus Telamonia?

A vague idea

Hi Alan, I can only place this one into a group of some collections that I have, but no more than that. How strong was the KOH that turned it black?
