Observation 59883: Sporormiella australis (Speg.) S.I. Ahmed & Cain
When: 2010-11-28
Herbarium specimen reported

Notes: This was on some deer dung that I collected while at Eagle Hill, Stueben, ME in August. I rehydrated it on 11/13 and worked this one up on 11/27.
The perithecia were partially submerged in the substrate, smooth and small – about 0.5mm.
Among other things, I saw Trichobolus zukalii, Graphium putredinis, Lasiobolus ciliatus, and Sordaria brevicollis.
