were not cystidia, there were no spores produced on them the spores are below them on the surface.

this feature is common to a number of crusts. large, spiky cystidia will give fertile surfaces a minutely toothed appearance. consider contacting Ryvarden, Karl Henrik-Larsson or Kurt Hjortsam.

I though the color was wrong, not like leather. But the teeth of this specimen are about the same size or smaller than the setae of the Hymenochaete.

all the true hymenial setae

I know of are pigmented. these appear to be hyaline. one could say it’s six of one, a half dozen of the other to put setae over here, and hyaline laceolate cystidia over there, but one could say a lot of things…

point being I don’t think this can be Hymenochaete with this color of “teeth”.
