Collection location: Sauvie Island, Oregon, USA [Click for map]
Who: Sava Krstic (sava)
Growing on barkless logs, gregaiously.
Spores ~15 × 5 microns, with 1 or 3 septa. The basidium in picture was 50 microns long.
This species should have “arthrospores” (in chains), which I was unable to find.
Can Dacrymyces have cystidia? See last photo.

I was not searching for clamps with determination. Just added two crops from the lousy microscopy done yesterday. In the first, there might be a clamp visible. The second shows the curved spore ends; you tell me if these are apiculi.
Spore thinkness?—I don’t know. As for “sharply defined margins”, this feature is absent in more mature specimens, which become all wrinkled. Unfortunately, I don’t have a photo to show this.
The collection is dried now; I would need to go back to answer your questions more reliably.
The fruitbodies are solitary and scattered, stillatus is confluent and with not so sharply defined margins.
Are the spores thick- or thinwalled (very important!) and are the hyphae clamped or not (also very important!)?
Looks nice; will see if I can find something better in it. Thanks a lot, Irene.
I don’t think it’s stillatus you have here, maybe you can find something else in the japanese study?
The bulb-shaped cells could be ends of hyphae from the margin of the fruitbody.
