Stoykov DimitarHallo colleagues,

I need to consult a xylarialean collection. found on may, alt. ca. 1350 m.  It is represented by a small black tiny crust, pappilate minute stromata - granular in appearance. Developed on thin minute piece of coriaceous plant, but more likely part of wide herbaceous dead stem). Asci are about 60 x 7 micrometers.
Ascospores are smal, ca. 8-10 x 2.2-3.5 micrometers (mean = 6.1 (sd 0.6) x 2.7 (sd 0.3), almost hyaline, and brownish in appearance, ellipsoidal, in water look like with 2 guttules.  
I was thinking of genus Anthostoma, but stromata are multiperithecial.

Thank You in advance!

Dimitar
