Ok, laking even a photo, it would seem that this is beyond a rumor here. But you might have to trust me, this is a good obs. There were two slightly strange cap that came in, from a swampy area at Chapman Creek campground. I had them in my had briefly in the field, and we tried a number of names for them, but none of them seemed to stick. They went into someone’s box, and I forgot about them for the rest of the day, yet another strange unknown, lets move on.

They were 8-10cm high, with connical caps 1-2 cm diameter, 1-2cm high, dull brown, slightly striate on the margin, pale gills, slightly tan, glaborus darker stipe 1-2mm diameter.

After the weekend, Prof. Desjardin got them under the scope back at SFSU, and we had a discussion over e-mail. Turns out they had lots of thick walled incrusted cystidia. After going back and forth, the id that was found was Mythicomyces corneipes. Dennis checked with the original published description, and found it a perfect match.

He then went on to say, this had been found rarely since the 80’s up at the Yuba Pass, but there wasn’t a good id on them until now. He is going to change the id’s of material from the past also that is in the herbarium.

I thought it would be good to post the story here, even if it got away from me, and I didn’t get any photo in place. Since this is the southern most obs. of this species so far it seems.
