Collection location: Howarth Park, Santa Rosa, Sonoma Co., California, USA [Click for map]

Who: Debbie Drechsler (debdrex)

No specimen available

These keyed out pretty easily in Arora. And match several of the other observations on this site. Fruiting in association with Monterey pine in a rather large number. Pilei between 2.5 and 3cm. Stipes .7 – 1cm wide and all about 3cm tall. Note the minute scales on the cap, dingy ochre gills, olive toned pileus and, of course, the pronounced annulus. There were several specimens of another cortinarius fruiting with them. See Observation 6167.

With Cortinarius it’s always a good idea to cut through one or two whole fruitbodies to see the colour of the flesh in the cap, different parts of the stem, and side of the gills – and if possible, take a photo of it too.

Confusing then and now!

These were fruiting in a pretty big group along with some others with long, annulus-free stems. Observation 6167. And these had soft, textured pilei that appeared to change to hard, shiny as they aged. I think it had rained when I first saw them and, by the time I took the photos, it had been dry a while. Dimitar, a checklist would be wonderful and I’ve promised myself to get another dehydrator so I can dry specimens this winter, in which case I could send you one!

Most likely croceus with pine..

Sorry, but I can’t second the idea of olivaceofuscus, a species that grows with hardwoods. I have only seen it with Corylus and oak.
The habitat and colours points directly towards croceus, which is known both from North America and Europe. If I had found it at home, I would havwe called it that, but I hesitate to put a definite name on a californian collection…

When it’s young, the cap is a bit felty, but becomes smooth and slightly darker with age. The brownish girdles on the stem are also typical, but less pronounced in older specimen. The typical colour of the gills is a warm yellow, often with orange and olive tones at the same time.

I agree – seems like Dermocybe, but an interesting one!

C. cotoneus has a very non-smooth pileus. This is a Dermocybe, but who knows which one… In fact looks like a very interesting collection – this girdle of partial veil remnants on the upper stipe is very particular. Where these very young specimens? I can’t quite get the scale?

Debbie, I will put a short write-up/checklist for things to check at the time of collection per Genus. Like in this case, odor, KOH, etc. I would have loved to be able to look at the material for this collection.

This is a crazy suggestion, but this one looks like C. olivaceofuscus. (Kuhn), although that such an id would require a little bit more work, plus it doesn’t appear to have been recognized from our area. Or one of the many forms of C. croceus… Anyway, I’m so very busy today, not supposed to be doing anything related mushrooms until later…

Not cotoneus

You got me fooled there for a while, it’s not related to C. cotoneus at all, and too yellow gills for C. venetus. Wishful thinking on my behalf..
