Observation 11615: Cortinarius (Pers.) Gray
When: 2008-09-25
No herbarium specimen

Notes: These looked paler and less shiny to me than the large groups of C. alboviolaceus that dotted the general area (including one not more than ten feet away). Some of the photos show whitish mushrooms; others seem to show a trace of violet. I didn’t notice violet colors among these in person, only in some of the photographs upon review.

It’s possible that there are actually two species growing close together here, another batch of C. alboviolaceus and a bigger-than-usual colony of the species from obs. 11607, say, with the C. alboviolaceus on the right (as seen from the vantage point in the fifth photograph).

There’s a buried stump nearby. Corts are symbiotic with trees, as I recall, rather than saprobic, so the occurrence of several clusters near stumps is interesting. Possibly, when a tree dies it puts symbiotic fungi under stress and they then fruit especially prolifically each season over the next few years as a way of escaping from the “sinking ship”. Spores are their lifeboats in troubled times, and genetic recombination instead of vegetative growth or fissioning provides a hedge against the new homes having slightly different environments.

Cortinarius possibilities

If this has an unpleasant odor it may be Cortinarius camphoratus. With a pleasant odor it might be Cortinarius traganus.
