you know there’s a ton of diversity out there within species. sometimes they are squat and sometimes they are not, but the color changes are consistent with the species concept.

this collection is right on the money for western rubicundulus; I have never seen this sp. in the NE, and would be surprised if it was exactly the same as ours.

Here’s the straight dope from Rogers Mushrooms. BTW, he also mentions the cespitose nature of some fbs:


Did you follow my prior link to the Bojantchev photo? It is a perfect photo match with mine, and IDed by Arora! At least, I’m pretty sure that’s HIS handwriting on that paper plate!

Sorry to miss the NEMF and the Eagle Hill foray this month. We are off to Alaska, instead. Can’t do everything, when you are also maintaining a living household.

Your photo does not match the other observations on MO and the collection that came in at NEMF and was identified by Dr. Malloch and Noah. I will post the pictures soon.

I know this is rubicundulus.

But if you don’t believe me, how ‘bout Dimitar Bojantchev? We two don’t always agree, but I do respect his work with Cortinarius. Maybe you do, too. Check out his webpage here, where gosh, he shows some fbs just like mine! Go figure. Plus, I was at that Arora foray in 2005, too, where that plate of elongated rubicundulus is depicted.


Like I said, we see quite a bit of this sp. in N. CA, and like DB reiterated, it is distinctive and easy to ID.

this is rubicundulus. I held it in my hand and saw the distinguishing characters.

Oh well. It’s only a mushroom! It will still come up in a rubicundulus search.
It was so distinctive, I didn’t bother saving it.

for those who missed it first time ’round…

you can easily see the distinctive RUSTY BROWN spore drop on the stipe of one fb.

sorry I missed …

this tempest in a teapot!

Not sure where y’all collect mushrooms, but I have personally collected a LOT of rubicundulus in N. CA. It is a very interesting and quite distinctive cort. Lots of individual variation in fbs, across the species spectrum. Odds are this one was quite rain-washed, back when CA got rain.

Sometimes votes just don’t reflect reality. This is one of those times.

looks like that eliminates H. lutescentipes…

Cortinarius don’t radicate like this as far as I know, cap texture/coloration/style – everything about the fb’s really – looks like Hebeloma, looks like H. radicosum radicates like this, H. lutescentipes stains yellow
