Dear all,

since some days I enjoy scanning a piece of oak wood I collected behind the house I'm living.
So far it featured Orbilia aprilis, Mollisia ligni and Rhamphoria pyriformis.
This evening I checked for further species and I found an even mor tiny one than the Rhamphoria (there are still more tiny ones, I'm afraid...).

The perithecia have the shape of a lentil, the lower part immersed in the substratum, brown speckled, partially hyaline. Size (on the slide with cover glass) is 350 µm in dm. of the largest specimen I found.
The ostiole (again on the slide) measured 50 µm in dm. (quite large I think).
The asci are cylindric with a short stipe and measure 54,5-74,9 x 11,8-13,8 µm.
Paraphyses are multi-septated and sometimes branched (c. 3 µm thick)
Now the spores ( those made me think on Leptosphaeria by shape): they are hyaline and clavate with 3 septa and tapered at the septa. Size is (16,4) 17,7 - 21,9 (22,3) x (5,5) 6,3 - 7,6 (7,9) µm

Any idea is very appreciated!

Best regards,

Martin
