Observation 34603: Leptogium saturninum (Dickson) Nyl.
When: 2003-07-19
No herbarium specimen

Notes: I don’t think this is Tremella foliacea. It was on wood in a mixed forest.

You’ve convinced me, zaca

I think I can convince myself now that there really are both isidia and thin tomentum. Moreover, I looked at all my own photos, and sure enough, specimens in moist areas do often grow with the same Tremella-like habit and have virtually invisible tomentum. Thanks for making me take another look at it!

What a tricky photo. Good on you for getting it right off.

[EDIT: And good job, Walt, finding it. Apparently it’s an unusual find in that area, and a beautiful specimen to boot.]

About what one can see in the photo

At the top there three (focused) lobes; The one in the middle, which is rolled, shows white tomentum; Moreover, there is another feature that tremelloide fungi don´t have: there are some villi at the margin of some lobes, good visible on the lobe on the center-left which directly receives the light; some other lobes also have some villi on the underside.

This does resemble Leptogium saturninum but…

I don’t see the tomentum underneath, and… I was going to say it doesn’t occur out east, but I see a few reports, Michigan, Georgia, Tennessee. I had no idea… Still, there should be visible isidia and tomentum. And it should be somewhat more adnate to the surface. I would be surprised if this were a lichen. That’s my two cents!

i’ve seen this happen to Auricularia in Tenn.
not saying that’s what it is…but, the prospect of Tremella, might not be far off.

jelly lichen?

Leptogium or Collema? Those two genera are characterized by, respectively, the presence or absence of a cortex, and in the field they are meant to be distinguished by differences in color and texture, but I haven’t yet reached that level of enlightenment. I may need to expand my circle of confusion to include Tremella.
