Notes: on half-rotten thin small leaf (herb?), scattered all over it
APOTHECIA: v minutely stalked, densely short whitish shaggy, disk slightly darker pinkish-brownish but still very pale, all parts K negative

There’s quite a selection of these minute fungi in Fungi of Switzerland growing on a host of improbable substrates, from dead horsetail stalks to leaves of a single species of Vaccinium, but all have those same cool paraphyses.

Summary: Microscopic details of hairs important.

In addition to relative size of spores, asci and paraphyses, glancing back through Fungi of Switzerland, I see that the hairs differ markedly from species to species. Sadly I have not taken the time to make the necessary observations.

Without a treatment that at least pretended to cover a sizable percentage of the genus (and possibly related genera?), I would feel very uncomfortable lumping this with any other species.

Summary: Dasyscyphus virgineus

Well, on woody substrate I found something I id’ed as Dasyscyphus virgineus, in the spring in the Sierras. Darvin found something similar that he id’ed as Lachnum virgineum, which I believe is a synonym.

Not sure what might make the difference between these and other lanceolate paraphases type guys, but you could group these together for now, since microscopically they look the same.
