Pleospora-like from sphagnum
Nina Filippova, 18-04-2013 18:16
Good evening.

Some loculoascomycet was found on leaves of sphagnum, probably somebody may have acquaintance with it. I am only fiddling around Pleospora, but have not looked seriously into the keys of this group yet.


Pseudothecia globose (130-200 mk), without stroma, site single at the surface of sphagnum leaves and at miscellaneous substrates, attached to the surface with many "hairs" (brown hypha arising at the surface at base and sides and outspread to the substrate), the same hairs but shorter arise from upper part.


Peridium from angular cells about 5 mk in diameter, hairs 3 mk thick at base; asci clavate - near globose, with 1 single spore, about 90 x 55 mk; paraphysoid tissue ("parenchymatic") present; spores muriform, hyaline when in asci, dark brown when mature, elongated with middle constriction at first, but enlarged to oval, almost globose when mature, with 3-5 longitudinal and up to 10 transverse septa, with many oil droplets inside, 64-81 x 26-46 (N=11).
