Michael BeugThe long-stalked cups were growing on Sphagnum. No sclerotium was present. Oregon Cascades, USA, 1100 m. Any idea what they may be?

Re : Unknown Asco
Something in the Sarcosomataceae - perhaps Donadinia or Plectania?

Re : Unknown Asco
Clarly a Sclerotiniaceae, perhaps a Monilinia. But I cannot read your scale. What is the spore size?

Re : Unknown Asco
The spore sizes (measured in the asci) were 10-11 x 5-6 microns. In the field where I could not take images, a fresh mount showed some larger free spores and I noted that almost all of the free spores were already germinating  (spores seen in a squash mount of the cup).

The fungus was definitely attached to Sphagnum.

Re : Unknown Asco
The only Sclerotiniaceae that I have in my database on Sphagnum is Sclerotinia kirschsteiniana P. Henn., but that has minute (1 mm) cups and spores 8-11 x 3-4 (Hennings 1899).

Re : Unknown Asco
Thank you. I passed the specimens on to a colleague (they were observed by a team of four mycologists) and will try to get them out for DNA and further work-up.
