Observation 11186: Armillaria (Fr.) Staude

When: 2008-09-16

Collection location: Japan [Click for map]

Who: forestwander

Specimen available

The mushrooms pictured are a first time find for me. They were in great abundance on dead wood in one small area of a place I frequently visit. The young ones in clusters look a little different than the big ones, but I am convinced all are the same species.

The stems are as hard as wood, and break just like tough twigs. Overall the stems have a woody texture, and as you can see from the pictures, the stems peel back on themselves.

The gills are white, I am currently ripping a spore print using aluminum foil. We will see how that goes.

The smell is not mushroomy, more like spermatic.

It’s not an Inocybe. For one thing I don’t know of any Inocybes that are truely cespitose. I just wish the photos were clearer. I can hardly tell if it has a ring or not and I can’t get a clear impression of the actual cap color. It looks almost yellow-green in some cases.

Might be an Inocybe.
