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.

from this fantastic resource for ascomycetes


no un-id’ed ascos are safe.

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.

more likely a Stictis, or at least not anything like a Sphaerobolus. I can only access one picture, here:


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?
