Observation 32444: Dendrocollybia racemosa (Pers.) R.H. Petersen & Redhead
When: 2010-01-24
No herbarium specimen

Notes: Might be the same as http://mushroomobserver.org/32384.
And also this observation: http://mushroomobserver.org/32770.
On an old rotten Russula or Lactarius, cap 16 cm in diameter.
I brought it home, but it won’t last long.
Cut one on half. It was rock hard and difficult to cut.
Looked at part of it under the scope; no spores.
It might be a sclerotium for a mycoparasite, something similar to Collybia tuberosa or C. cookei.
Planted the remains, gills down, in my backyard. Hoping that something will fruit from the sclerotium.
Update – July 2012
Two winters have past by and no sign of a fruitbody where these sclerotia were planted. Looks like this experiment failed to fruit.

and maybe dry one, too.
is it a fungus? with a cap? or a myxo, as was also suggested? very weird, and obviously out and about in central CA right now.

Yup! That looks just the same to me… I wonder what it is.
