Hello.Fruitings between 51 and 130 microns in tota
I found this bitunicate ascomycete growing on dead leaves of Eriophorum angustifolium.
Pseudothecia are immersed, ca 100-150 µm diam
Asci are bitunicate, ovoid, 8-spored, 38-57 x 22-29 µm (only 2 asci measured). Sometimes immature and post-mature asci are present in the same pseudothecium.
Spores are mostly 22-25 x 5-6(-7) µm, in one sample rather larger (<31 µm long). They are 1-septate, slightly constricted at septum, and sometimes splitting at the septum into 2 parts. Spores are hyaline, becoming dark brown when old, with 2 large oil bodies/cell when fresh, and with a thick gelatinous sheath. The spore wall appears to be minutely verruculose in old spores.
I think it belongs in the Pseudosphaeriaceae. I had wondered about Monascostroma innumerosum but the thick gelatinous spore sheath seems to rule out this species and suggests Wettsteinina. The closest fit in Shoemaker & Babcock's 1987 paper on Wettsteinina is probably W. junci, but the description doesn't fit in all respects, e.g. spore dimensions are given as 26-31 x 9-11 µm (i.e. rather larger than in my specimen). Another possibility is W. waltraudae, described by Scheuer and not included in Shoemaker & Babcock.
I'd be grateful for any suggestions.
Thanks
Marcus
