Observation 146475: Cortinarius subgenus Myxacium (Fr.) Fr.
When: 2013-09-22

Notes: These were growing on the ground in mixed conifers @ ~ 3700 ft.
Caps and stipe viscid.
They are relatively small, with caps up to 3.5 cm across.
Spores on the other hand were relatively large, ~ (13.0)14.0-18.1 X 9.0-11.9 microns and moderately rough.
Haven’t been able to match them up with the more common Myxaciums.
Could be the same as http://mushroomobserver.org/184116

They do seem to match what Steve Trudell calls C. muscigenus in “Mushrooms of the Pacific Northwest”. However, he said they were medium to large in size while these seemed rather small. Also couldn’t find specific spore data for that species.
Another case of an European name that will eventually be revised for similar North American taxa?

In the C. elatior / vanduzerensis group

This is an interesting cort in the C. elatior / vanduzerensis group. I bet the pileus hyphae are clampless. The spores show me that it is not in the C. mucosus / muscigenus (not a very good name) / collinitus group. I have seen this one time in OR, but not in California. Ron, please save the collection.
