Maren KamkeHi everybody,
I thought of M. typhicola, but the ascospores are smaller and the sporesurface is smooth, it is rough at M. typhicola.

Dates:
On poaceae-species, immersed in substrate, 0,25 mm with ostiole, wall of the perithecia about 20 to 25 µm. Spores 5-7-septate, mostly 5 to 6, sometimes 7-septate, with transverse septa only. Colour yellowbrown, with slimesheat, young hyalin. According to 5 or 6 septa, is the 3. oder 4. cell slightly enlarged, messurement (24-30,5) 26,4 x 5,85 (5-6,5) µm, Q 4,5. Asci 107x8, 8-spores.


Regards, Maren
