Hi everybody,
This collection was collected by Jörg Gilgen on a very decayed Polypore (Inonotus hastifer) and initially thought to be Dialonectria cosmariospora. However, it wasn't... Maybe I am on the wrong track because I think of the species as fungicol which it probably isn't?
Substrate: On rather decayed Basidioma of Inonotus hastifer
Perithecia red, pyriform, 200-300 µm in diameter, 250-350 µm high, wall smooth. Perithecia turn purple in KOH.
Perithecial wall up to 20 µm in thickness, composed of mostly elongated, thick-walled cells.
Asci 93-98 x 6-7.5 µm, cylindrical. Spores 12-15 x 5.8-7.3 µm, two-celled, with a non-constricted median Septum, light brown, filled with many small, brownish guttules, walls in water mostly appearing smooth (sometimes very inconspicuously ornamented). In Cotton Blue the ornamentation is just visible but still very inconspicuous.
Any suggestions are welcome,
Many thanks and best wishes,
Stefan
