Thelenellaceae?
Björn Wergen, 13-09-2012 10:24
Björn WergenHi all,

during my Austria vacation I have found a small pyrenocarpous fungi growing on dead bark of ?Populus (@Gernot: this was the tree where you have found L. compressum) in 1,50m hight. I do not know if it is really a lichen of Thelenellaceae or something, but perhaps you can tell me. It has very small spores (2-3x1,5µm) and polyspored thick-walled asci, which react faintly blue in Barals (with stronger concentration orangered). Distinct blue react the periphyses and the subhymenium. 

Macroscopically the fruitbody seems to be a perithecia (?), very small, about 0,2 mm and black with white inside.

regards,
björn
