Collection location: Dallas, Pennsylvania, USA [Click for map]

No specimen available

At first I thought this white stuff some spider web that got stuck onto the gills of the laccaria mushroom. But several of the mushrooms, all older ones, had similar stuff on the gills.

Recognized by sight: I’ve seen these “spider webs” many times before on Laccaria and other mushrooms. I still don’t know what exactly it is, but I always presumed it’s not part of the mushroom and caused by insects.

the same thing at another location, and scoped the white stuff.

Can you put some of the white threads on a microscope slide and check it out?

That was my first thought, Irene.

But most of the older caps showed the webby stuff underneath, and I did not see remains of spider webs anywhere else on the lawn. I suppose that rainfall could have washed away the webs that were out in the open, and like yo say, Irene, the parts under the mushrooms were protected. We did have a heavy rainfall a few days ago.
