When: 2011-04-24
Herbarium specimen reported
0 Sequences

Growing from a crack in a hardwood log (probably cottonwood).

Spore print white. Spores 8-10 × 7-8 microns.

15 March 2013

Basidia mostly 2-spored, but 3- and 4-spored observed too. Basidia ~33 × 7.5, with sterigmata 10 microns. Cheilocystidia forming sterile band, ~38 × 9 microns. No pleurocystidia. Diverticulate terminal cells on stipe cortical layer observed (no picture).

M. galericulata, or some of the closely related Mycenas there. Thanks, Irene. The spores are a little wider than any of the ranges in the table on http://home.online.no/~araronse/Mycenakey/galericulata.htm. And I haven’t seen any excrescenses anywhere; maybe I was not looking properly.

Mycena galericulata to me. The spores are a pretty good match too (the “dirt” is not on the spores, it’s inside them).


I wonder if a sharper picture of the cystidia would show the same structure – but micro drawings usually exaggerate the characters, and the description says that the excrescences are few to numerous..

What is that “dirt” on the spores? I (mis)interpreted that as non-smooth.

The spores look smooth to me.

Christian and Alan, when I found these I also said “Mycena” because it looked similar to P. purus. But aren’t Mycena’s all supposed to have smooth spores? These spores don’t look smooth.

I added some more microshots. I also looked at stipetipellis and so nothing particular there.

Two features that cannot be seen on the photos: stems are hollow and (some) gills are slightly pinkish.

Spore measurements: (9,7) (8,8) (8,7) (8,7.5) (9,7) (8,7) (8,8) (9,7) (10,7).

Great two horned cells. I guess they are more likely to be basidia than cystidia.

Those two-horned cells

look like basidia that are only partially in focus, (they might actually be two-spored).

Added two gill shots that show some two-horned cells. They were the only features to stand out.
