Observation 34900: Cortinarius subgenus Phlegmacium (Fr.) Fr.
When: 2008-09-05
No herbarium specimen

Notes: No specimen for this one, unfortunately, just another largish Cortinarius fruiting in the same place (relic dune pine forest) and same season (September) as the ones before (34865, 34878). The autumn of 2008 was unusually warm and long, so it fruited till mid-October (3rd and 4th images).

Aleksandr Lozovoi @ mycoweb.borda.ru forums guesses that it’s Cortinarius multiformis. Relatively pale gills, smoothed bulb and color fit, but again I’m not sure about the habitat – it’s said to prefer Picea forests and not sandy-soil, well-lit Pinus forests.

That’s the typical evolutionary pattern…

…that the curious collectors follow when getting deeper into something. I wasted a lot of interesting collections in the first year of collecting because of improper handling. Started with photos, then in a few months that wasn’t enough, got the microscope, then started to collect the spores on slides only, then the full thing, now getting to expand in newer methods.. All driven by insane curiosity.

The field kit is simple – waxed backs and 2 knives, one in each pocket. First thing when back is not to sit at the microscope, but to take the key notes. Short(!!) and key notes, no point in lengthy descriptions – efficiency above all. Then dry the material – the idea is that you collect, but don’t turn into a complete slave of the collections. Well, I have, but only when I deal with 30-35 Corts in the evening… You will have all of the time to do the microscopy when the season is over and everything is covered in snow (in your area, in California the grass burns in the off season :-) Emphasis at the time of collecting is on preservation only. Watch for mixed collections – you will undoubtedly make some, but be very sensitive, particularly if you see large crops with 3-4 different species intermingling..

Anyway, have fun..

to lay my hands on the mentioned data, too :D Right now I’m sorting through my photo-mess as part of the preparation for upcoming season, and it’s really inspiring that some local fungi (e.g. Amanitas and Cortinarii) are interesting not only to me – didn’t really expect anything like that when taking those pictures.
Got it about KOH; I’m thinking that maybe having a sort of a field-kit (and maybe a field notes form?) at hand will help make my future Cort findings more useful. I’d really appreciate any ideas on that matter… (P.S. and Dimitar, thank you very much for the visual very howto link!)

We need more diagnostic data

Nice collection Tatiana, but now we need to start presenting some
more diagnostic data in order to have a good chance of getting
closer. Here is a link that I have prepared for Cortinatius
collecting.

I agree that this is not multiformis with this bulbous stipe, but
there has got to be a bit more blue on the stalk to see
caesiostramineus either. I have a couple of secret guesses, but a
bit of extra diagnostic data could lead us a long way. For
Phlegmacia you really need to apply some KOH.

I’m not sure

about the multiformis group either. They usually get a striate brownish yellow tone on the stem. And they smell like honey.

The habitat and looks on these corts point stronger towards a form of C. caesiostramineus. Usually a clubshaped stem with or without a blunt bulb, greyish to pale yellow/ochraceous caps, pale gills, sometimes with a pale blue hue on gills and top of the stem. To these characters you have to add a bitter cap cuticle.
