No specimen available

Just came across this in some old files. Apparently it was one I failed to identify in my earliest experiences with mushrooms. Only info I have is the collection site … grass with Oak associates.

Walt – psittacinus vrs. perplexus

Looks like the west coast psittacinus is going to have to be studied to tease out species status. A recent DNA sequence of what I was sure was going to be an undiscribed perplexus turned out to match one Christian Schwartz did from southern California. But I believe these two do NOT match east coast G. psittacinus. Christian hints at all this in his recent book. Going to be fun to watch!

What I expected to be a perplexus – has zero green even from the button stage. The buttons are brick red or flesh colored.

How about Humidicutis?

Lack of striations on cap makes me think Humidicutis. The green fits. If you look at the Humidicutis from the west coast (var olivacea) there is plenty of green. Not as bright underneath as most Humidicutis, but within the range maybe?

… and much to the consternation of rank amateurs, such as

myself, I might add. Seems there’s enough work yet to be done on mushroom taxonomy to keep the mycologists busy for hundreds of years! Thanks so much for your feedback.

psittacinus and G. perplexus are considered different species by many mycologists now. If it weren’t for the green on the one cap I would have voted more strongly for G. perplexus. Gliophorus psittacinus is a chameleon and soon loses its pretty green color. Calling it G. psittacinus group is probably the safest answer. It seems many species are turning out to be groups much to the consternation of old field mycologists like myself.

Walt and Jacob, thank you both for your nearly instant

ID’s. I should have posted that back in 2015. What would you think of Gliophorus psittacinus var. perplexus (Mycobank)?
