Mushrooms Around The Yard
Collybia dryophila aka Gymnopus dryophilus
in Shrewsbury? The spore shape and size says it is not! Growing on a
pile of oak leaves. About 3" high. The cap of the larger is 2".
Stem hollow, a bit tough. I would not call it brittle. Lincoff
states that Oak-loving Collybia is the one that hosts Collybia Jelly aka
Bottom of stem.
The spore print was white. Spore size
about 10 microns. They look spiked or warted.
