When: 2009-10-11

Collection location: Strouds Run State Park, Athens, Ohio, USA [Click for map]

Who: Dan Molter (shroomydan)

No specimen available

This little mushroom is a total mystery to me. It was growing from a stick in a gully between two steep hillsides. Mycellium has covered the stick and turned it white. So far, this mushroom has not dropped any spores.

Looks somewhat like a Callistosporium sp. But would have liked to see some microscopy.

I enlarged the photo as large as I could.

While the gills could be construed as notched, they are not what I would call serrated, as the teeth of a saw blade.

As for what the fungus is, without a spore print I’m unwilling to guess.

What about the serrated gills

The gills are serrated what other species have serrated gills If double click the image you can enlarge it and it appears the gills are serrated,

Not a Lentinus or Lentinula that I’m familiar with.

I’ve grown Lentinula edodes for about 20 years now. L. ursinus typically much larger, and would not be on such a small piece of wood. Pluteus seems possible, but atypical for most of the species I am familiar with as well.

Don’t think this to be Lentinus … it reminds me of Pluteus.

Thanks Eddee, I had not though of Lentinus, but it seems possible. I have the mushroom outside. Hopefully it will drop a few spores tonight.

could be Lentinus

Hey Dan Just blew up your pic 60343,well not literally but made it bugger. It appears the gills are serrated and growing on wood that would place it a Lentinus of some sort.
