Observation 28051: Cortinarius colymbadinus Fr.
When: 1989-09-01
No herbarium specimen

Notes: Please excuse the lousy picture, scanning from a 20 year old photo didn’t make it better. The date is not exact, just my best guess. This particular obs was made rather late in the season, but it often occurs very early (june is early here).

I’m adding this obs because zinziberatus was mentioned by Andreas and Walt in a discussion about Cortinarius scaurus.
Anyway, with the added info, it can serve as an example of what we have in Scandinavia too.

I’m not sure what to call this cort, because the names around it are interpreted in many different ways (isabellinus/spadiceus and zinziberatus have also been mentioned in the discussions, but none of them very convincing).
Cortinarius colymbadinus is said to grow in old, herb-rich spruce forests on calcareous ground. This one did, but was found among mosses and leaves under a large stand of aspen. Other corts I remember around this spot, were C. canabarba and the smallish spruce form of C. calochrous.

thank you Irene. It looks quite similar to what I call zinziberatus. I have just now a discussiomn in mycologia-europaea forum, about a collection from a calcareous thermophil Quercus-Sorbus torminalis forest, which I couldn’t name and which also is quite similar to our Picea-zinziberatus. I will just load up these two collections, under the name zinziberatus but without being totally convinced about the name. Unfortunately my specimen of the Quercus-collection moulded before I could dry it properly and I had to through it away.
