C. aavae…

has been collected in September and October. The spring fungi seem to be very different than fall fungi, if you could this collection as a spring collection.

I checked the Consortium of the Pacific Northwest Herbaria and there are ca. 47 specimens of Cortinarius vernus and all of them (except one collected by Patrice Benson) were collected by Oluna. Oluna says that she is not too happy about that either what else one can do in order not to get our collections lost in the Cortinarius pile. Just three days ago, we made another collection of the same Cortinarius. To call it “Cortinarius vernus sensu Oluna” would be the most correct, but rather phony. Oluna noticed that there is quite a variation in presence or absence of marginal cells and in the degree of spore ornamentation among her collections. All of them are the earliest medium size Telamonia that we encounter in early spring.

I object to every brown cort being called C. vernus.

I don’t think that C. vernus exists in the Pacific Northwest.

This specimen makes me think of the C. aavae collection I have, but the spores are 0.5 -2 um larger than the description, which is why I went for C. leiocastaneus. However, this species was described from Finland and Sweden with Betula.
