Usually, I have found collections or been given collections that had the blue-green stain. It would be interesting to know if the color change is more probable under specific conditions. I have no ready answer.

Dr. Tulloss, are there variations of A. pelioma?
one bluing and one not?
Or has this idea yet to be studied?

I agree that the shape of the bulb is a good match for A. pelioma, (compared to the pictures on WAO)

I think you’re right about the ID.

So far as I know there are two alternatives in eastern North America when you find cafe au lait gills in an lepidella. The alternative with a powdery volva very much like that of A. cinereoconia in terms of texture is pelioma. The althernative with many well-formed little pyramidal warts is A. microlepis. The first type of volva seems to be what you have here. Also, the shape of the bulb is good for pelioma. I think that you found it again. Nice find. I can’t remember ever seeing it in New Jersey. I know of one collection from the Catskills in New York state.

Very best,

Rod
