I’d make my assumptions based on substrate (and size), rather than area.

I believe would be an important tool. Scopes and past experiences cannot be overlooked either. However, since most of the posts on MO for this species are by you, and most on conifer, Im wondering what literature you used to assess this. Darv, Irene and I have mentioned that our experiece has been to find the literature pointing to NOT conifer. If you could cite an example to look at, much appreciated.

In the past…

In the past many, many years, small yellow-orange ascos have been looked at in the Yuba pass area of the Sierras. In that area at least, they are D. bicolor, it would be safer to assume the same for Yosemite. But I agree that people should get more micro-details with good photos on the scope to post here, for several obs. over a few years, to see if there is a distribution between Dasyscyphus and Lachnellula in the Sierra Mnts area. But until then, I’ll go with the current knowledge and call these D.bicolor.

I think Mike Wood has looked at a few of these, and might have another opinion.

Size?

I could be wrong, but they look larger than an average Dasyscyphus(Lachnum), which usually are around 1 mm.
With a larger size and growing on conifers, they are more likely Lachnellula sp.
Among the larger ones (<6 mm) known from Europe with a broad host range (Pinus, Larix, Picea etc.), are L. suecica, calyciformis and subtilissima.
Microscopy is needed, of course..
L. occidentalis grows only on Larix, as far as I know.

Camp? like back at the camp?…West coast have players/haters, DNA runners, scope technicians, quiz shows, camps…. East coast is asleep at the wheel over here.

pine, probably. This was the name I was told at the camp (I don’t do ascos). Could very well be something else.

RWG Dennis has the common sustrate as oak twigs. Switz says oak and ash.

I know that

you have way more conifers there… Do you know what kind of wood it was on? Dasyscyphus on hardwood Lachnellula on conifer. Could also be calyciformis

The margin looks too thin to be D bicolor.

Sweet shot!
