When: 2011-12-03

Collection location: Larch Mountain, Multnomah Co., Oregon, USA [Click for map]

Who: Sava Krstic (sava)

Specimen available

Notes:
Growing on dead branches, logs, stumps, in a coniferous forest. Found it in countless places today. Shorter-stemmed than what I was seeing a month ago. Odor the same—-slightly farinaceous. Stem always strong yellow.

Typical spores 9.5-10 × 6.5-7 microns.

Which of the numerous varieties of epipterygia this one is? Maybe we’ll find out later.

in fact, until recently, I had no idea that these temperate mycena sp. glowed in the dark! but in further research, it would appear that ONLY the mycelia glows, which is far less dramatic and pretty darned difficult to see in the field!

altho it might just explain the stump that I saw glow at Huckleberry. It had Omphalotus all over it, which I assumed was the source for the glowing wood, but also contained the mycelia of Mycena maculata, which supposedly has bioluminescent mycelia.

Not so easy to sort all of this out!

I never tried to check bioluminescence in any of the Mycenas I collected. I guess I should start.

have you ever observed bioluminesence in this species, Sava?
