Coming from you it means a lot.

Thank you Irene. I haven’t read Bendiksen & Bendiksen’s paper in Persoonia yet, but plan to get it from UC Berkeley soon. I am pretty sure that it all boils down to a type collection irregularity, otherwise Kauffman was very, very clear that cylindripes is not collinitus.

They inspired me to read Kauffman’s description of Cortinarius cylindripes in Ohio Mycological Bulletin, and it fits very well with this species. I don’t understand how it once was able to be synonymized with collinitus, but it’s not anymore..
The european collinitus is quite different, with a reddish brown cap, not fading. The stem has a smooth bluish slime cover, not girdled, but often cracking into patches when drying.

Nice forest you have there…

Nice forest you have there Dan and I wish had those Corts to play with… we ought to examine absolutely every Cort carefully and never just put “wishful thinking” ids. We really need to do the Cort ids right as this part of America hasn’t been touched for 70-80 years and who knows what species are hidden.

I will make another trip to the East Coast later in the season, perhaps not this year, and your forest over there is definitely to be looked at again…

As far as this one, I am not ready to settle on the name cylindripes as there are issues — Bendiksen, Bendiksen & Brandrud examined the type collection and decided that what is there is something other than the described species. But I want to read that article first.

In fact, now I am bored with Calfiornia and wanna go back East…

Nice spore shots

I was wondering what you would come up with for these. Irene’s comment about bitter cap slime actually prompted me to lick the cap of a slimy purple Cort yesterday, ugh. Whatever this mushroom thing is, I must have it bad, wandering around in the rain licking slime off the caps of little unidentified mushrooms, Haha!

I thought the cap coloration was off for C. iodes in this observation. The little purple guy I licked yesterday also lacks the characteristic yellow splotches. It can be seen here:

This turned out to be an interesting collection.

This large spored Myxacium seems to display affinity towards
Kauffman’s original concept of Cortinarius cylindripes, which due to
unfortunate circumstances (in my opinion) some authors synonymize with
C. collinitus Fr. I haven’t gotten a hold on Bendiksen & Bendiksen
article that examines the Type Collection, but I still find it
unfortunate because Kauffman had a very clear idea of what collinitus
is (in a contemporary sense too) and how it differs from cylindripes
and in fact the descriptions are not even close when lined side by
side in NA Flora (1932). Kauffman also has a photo of cylindripes from
1907, which clearly shows it nowhere near the well known and easy to
id with its girdled stipe, collinitus.

There are some other shots of the large spores.

Yes, I have them.

Myxacium, yes, clearly so. Irene, taste not bitter. C. iodes was probably not a good first reaction. Have the material, they also gave an abundant spore print. Will review what Kauffman and Peck have for these, but the salor vicinity sounds quite reasonable.

Good collecting with Dan, he is officially certified as a “Nice Guy”. I’m in Cleveland OH at the moment checking my old college places and some old buddies. Can’t wait to get home and turn my scope on hot and the books wide open. Lots of cool stuff all around. May investigate Indiana and then Michigan for the rest of the week trying to reach the conifer zone over there. Lots of other impressions to share on MT when it all settles down. Hard work too — processing all of the collections is just hard labor.

iodes

I was with Dimitar when we ran across these pretty little corts. He thought it was c. iodes. The pattern of yellow and purple on the cap seems off to me. He took a few home with the intent of subjecting them to microscopic examination, so I suspect we will know soon enough.

Looks like something close to salor, maybe iodes (or iodeoides if the cap slime is bitter)?
