Observation 12225: Collybia (Fr.) Staude

When: 2008-10-04

Collection location: Forest near Elgin St., Pembroke, Ontario, Canada [Click for map]

Who: Paul Derbyshire (Twizzler)

No specimen available

Yep, it’s another observation of those “little cluster-dust marasmii”, or whatever the heck these are. Always they pop up in pine-containing woods in little clusters like this of dozens of tiny mushrooms of various states of maturity in an area only a few centimeters in radius. From the perspective of a hiker walking by, at first it looks like a spray of whitish flecks on the ground.

Up close, it’s lots of little white mushrooms, the mature ones with darkened centers.

The growth habit is particularly distinctive, and this gives me hope that these can be id’d.

Recognized by sight: Is it growing on blacken remains of old russulas, etcl? I think it is Collybia tuberosa or C. cookei. Next time you find it dig it up and look for little tubers. C. tuberosa has apple seed like sclerotium, C. cookie has irregular shaped (1/8-1/4”) yellowish sclerotium.
