This very tall Mycena grew nearly 9 inches tall in several groupings from recently logged slash, I think. Mostly, there was grass around it. CAP: ruby-red center of conical cap, becoming red, orange, and finally pale ochraceous; GILLS: pale pink to slightly yellow-tinted; STIPE: very long and strong, black-red at the base, with several black to nearly yellow-white strong rhizomorphs attaching to either soil or woody debris, becoming dull marroon about 1 inch from base, which color extends to within an inch of the cap attachment, then enlarging slightly and becoming orange-red and slightly scruffy. A very pretty and quite large Mycena. I didn’t think to check the stem for bleeding, but the stipe looks too strong in my experience to be M. haematopus. However, that certainly is a possibility.

Stipe only 6 inches (15cm) tall

Returned yesterday to say location, found specimen still untouched but with a distinct twist in the upper stipe, which measured only 6 inches (15cm). Still, much taller than M. plicatulus described in Arora.

Could be, but

I don’t know why I didn’t consider Marasmius. The specimen matches the description in Arora almost completely. The one exception is a strong extension of known parameters, though. Arora states stipe is 5-13cm long, this stipe is nearly 22cm long. I will be going out again tomorrow to Paul Bishop’s for his annual pre-NATS Fall Truffle Dinner, and hopefully will collect and measure other specimens. There were several at nearly the same location this specimen was found. But certainly this specimen looks like it has “pleated gills”, and Arora does name M. plicatulus Pleated Marasmius. So … could a stipe be nearly twice the length of the longest stipe currently known?
