Original Herbarium Label: Stictis radiata (L.) Pers.
Fruiting bodies are embedded in the bark of madrone (Arbutus menziesii). They have an orange center, the hymenium with narrow ascii and filiform paraphyses. In each ascus there are 8 ascospores, about 200 µm long and 2 µm wide. Common on Arbutus menziesii on southern Vancouver Island.

I was hoping you would be around after I got back from ACCF having seen Oluna’s presentation, because she showed this image and I turned to Peter and Douglas and was like “hey! That’s that thing Danny brought in the other day!”
I told Alan what it is and he said he would post a photo- I am sure it was Stictis radiata or else a species macroscopically identical.
which shows some of the orange Alan and I observed inside of these white-rimmed depressions in the madrone bark. When scoped, the white “crown” surrounding the outside wasn’t much to look at, but the orange — once sectioned away from the bark and out from its cavity (like trying to perform an appendectomy on a sea monkey) — looked just like what’s seen in Oluna & Adolf’s micrograph here.
the two duplicates before it should be deleted.
Judging by the micrographs, I’d think Alan and I found this same thing (or a variation thereof) growing on madrone bark in Strawberry Canyon above the UC Berkeley campus. Extremely small and a nightmare to dissect. Was there a semi-spherical orange growth in the center of these?
