and was surprised to find that the fruit bodies have matured and nearly rotted. They did not get much bigger than when first visited two weeks ago.

You may be able to find Redhead’s paper on jstor or through the msa. Latin descriptions of A. aspratus and L. asprata are available from librifungorum-


Supposedly this species looses its tufted floccose scales as it matures- breaking up into unorganized hair like fibrils. Your collection, and most collections in NA on MO look to me like they are hirsute to granulose, bordering on glabrous.

Thanks Dan and Rocky

My assessment when looking at it in the field was that it is Cyptotrama; It was my mistake to use Cystoderma; I will add the one photo I have showing a tiny bit of the gills, which were white. Obviously the FB is very young and may not have spores. I don’t know how to distinguish the species within Cyptotrama. Can you suggest a reference? It is not even listed in Kuo.

At least 15 taxa in Cyptotrama, are we sure this isn’t another species? In fact, without a picture of the lamellae, can we even be certain this is in Cyptotrama?
