When: 2009-07-09
Herbarium specimen reported

Notes: Found these growing next to xxx on/binding conifer needles of mixed forest. Spore print pure white. I have a specimen and can do microscopy if this observation interests anyone.

Further observations: Pileipellis is a cutis. Cheilocystidia present (see photos). Spores elliptical, roughened, about 5.5 × 3.5 µm. All of gill tissue turns bright green in KOH, especially cheilocystidia.

Looks like Gymnopus alkalivirens or close to it…

See updated notes. Found an interesting discussion under observation 20693. Keyed it out using the SVIMS collybioid key: http://www.svims.ca/council/Gymnop.htm#n17a. Pretty close to G. alkalivirens (spore length:width ratio is a bit off, and they say the spores should be smooth in strong K, which mine aren’t).

I think it is Gymnopus

They look a bit like Gymnopus, but the colors are very dark. I’d also like to see what the scope can tell us.

I’m curious…scope it up!
