Cortinarius sanguineus.

After reviewing the dry material sent to me by Dorothy Beebee, there is no doubt in my mind that this is Cortinarius sanguineus. The other probable species C. californicus has larger and rougher spores. Plus, per D. Beebee it tends to produce brownish pigments. D. sierraensis is out of question as it is a very narrow habitat species known only from the High Sierras under Lodgepole Pine (per J. Ammirati who named it, as well as regularly collects both in the mountains and on the coast and ought to know).

I can’t add the spore shot image to the observation — here it is:


There’s Nothing impressive about the spores of C. sanguineus…

Red Dermocybes found at Breitenbush Hot Springs by Dorothy Beebee

“These specimens were found growing on decaying (cubicle brown rot) Douglas fir stumps and logs, actually growing OUT of and IN the wood, specimens emerging between the bark and the cambium layer. (I had never seen that growth habit in a Dermocybe before. The area had been logged by the F.S. about 26 years ago, so it was second growth woods of D.fir, hemlock and some Grand fir as well as pines (sp?)that had been introduced. There were piles of burned wood nearby. Undergrowth in the area included berberis, cornus, bracken fern, blueberry, and creeping manzanita around the burned area where the mushrooms were found. Within 2 feet of these red concolorous Dermocybes were also growing flushes of D. semi- sanguinea, D. phoenicea and several sp. of orange and yellow gilled dermocybes – all within arms length or each other,all intermixed in the duff. No moss, no spruce. Only the red Dermocybes were growing on the wood. The gills had a shimmering red iridescence, tending more toward red-orange tones rather than the deep clear red of the D. sanguinea that I have previously collected in Sweden and Finland. Another flush of these red beauties had been found a day earlier by the foray group led by Dr. Susan Libonati-Barnes in a similar habitat at a higher elevation of 4000 ft, with lodgepole pine nearby, but in the same type of habitat – growing out of cubicle brown rotting Doug fir with burned wood debris nearby. An on-the-spot dyebath experiment (boiling water poured over a chopped up cap), produced the same colors on premordanted (alum=red and iron=purple) wool and silk that are routinely produced from D. sanguinea, D. semi-sanguinea, and D. phoenicea. Cortinarius californicus produces an entirely different range of hues – toward rusty orange with all mordants… " Dorothy

Can you share the logic behind the id?

Macro and micro reasons to believe this is different than sanguineus.
