Im having a hard time finding anything about H rubiginosum in the anamorph state. Mykobank has no listing, and the Xylariacea site http://mycology.sinica.edu.tw/Xylariaceae/ does not have any images with this likeness.

Agree this is a xylaria most likely.

Do you have any literature on this? Any web resources I could scour through?

Thanks!

if one looks if the fruitbody has tiny ostioles or not. Crust fungi as a rule do not have these. Ostioles are very fine openings and make the surface appear as if dotted or punctured. Through these holes the spores are dispersed when mature. But in H. rubiginosum this is almost impossible to see. Or with a microscope. Hypoxylon are ascomycetes, crust fungi are basidiomycetes. This greenish yellowish bloom is commonly seen in the asexual state of Hypoxylon during early spring to early summer.

Thanks Gerhard, I agree that it looks like Hypoxylon…,

Photos of Peniophora have a thicker crust. I think I am seeing two types of Hypoxylon now – the rarer looks like these photos, pink going to black, sometimes with temporary white fruit bodies that wash away in the rain. The other can be bright orange with a yellow edge. I will post these soon. They sometimes also have perimeter fruit bodies and appear to be fading to the familiar chocolate brown.

So this looks

like the anamorphic state of Hypoxylon rubiginosum or the likes for sure.

Thats exactly what

ive been seeing, but i dont think that the white perimeter is a parasite, but part of this crust. Tom Volk would be able to clear this up most likely.
