Observation 27266: Cortinarius (Pers.) Gray

When: 2009-10-22

Collection location: Luzerne Co., Pennsylvania, USA [Click for map]

Who: Dave in NE PA

No specimen available

Well, there likely many possibilities for this small yellow cort (about 3 cm diameter). But spore size/shape and color of fruit body appear to match glaucopus.

I’m not saying that the mushroom is C. glaucopus. I have little confidence in IDing the vast majority of Corts to species. That’s why I initially rated my own confidence as “Could Be”. Phillips’ description of glaucopus fails to mention the sticky cap… and I suppose that’s one feature which causes one to immediately exclude galucopus as a possibility. What’s a good reference for C. caesiostramineus?

I did not check for taste. There was only one specimen found.

Hmm, interesting…

The colors and spore shape/size do not exclude C. caesiostramineus at all, but rather support it… I’d have liked to see more than one fruitbody.


P.S. C. glaucopus is totally and completely out of question.

Makes sense

with 500x magnification, and then the smallest parts in the scale equals 2 microns. That means that the spores are about 8×5 microns as they should.
The habitat, size and colour of this cort, as well as the spores, fits caesiostramineus – but did you taste it?

The overall color

of this small dry capped Cort was very light. Under spruce.

When I purchased the used microscope from a college bio dept a few years back, I had just assumed that the scale was marked in lengths of 1 mu. I think the magnification is 500×. I’ll consult the bio profs to get verification on this stuff.

C. glaucopus? No way

maybe C. caesiostramineus if the cap cuticle is bitter, and spores around 8-9 × 5 microns. I’m not sure what magnification you are using in the micro shot, or how to read the scale..
