Observation 18793: Mycena (Pers.) Roussel
When: 2009-02-23
Herbarium specimen reported

Notes: Found these in moss in Nothofagus pumilio forest. CAP 10 mm, glabrous; GILLS somewhat dark-marginate especially when dry, I see minute dark red dots on the gill faces at 20x but I’m assuming these aren’t the spores(!!)… makes me think twice about checking spore color by looking at gills with handlens, though!; STIPE bleeds very dark brick-red at base. How many species of Mycena bleed red?

(number 0223.12, page 177)

Why no overlap between NZ and Patagonia?

Seems there are lots of circumboreal species, why not “circumaustral”, too? Well there is that whole big ocean thing going on…

More bleeding Mycenas

We also have Mycena sanguinolenta which has marginate gills, but it’s not that either.

This looks similar to the New Zealand M. mariae but I doubt that it occurs in Argentina

Guess so…

It certainly looks like a Mycena, that is good enough. Although they also look a lot like M. californiensis… except they are not on oak duff.

Then better to leave it at just “Mycena”…

Mycena haematopus not marginate

These are marginate, M. haematopus not marginate. Actually M. californiensis is marginate, and also bleeds red when cut in the base. (I have this right don’t I?)
