Good afternoon.Does anyone know this anamorph?It g
The first one was already published here previously, Physalospora vaccinii which is found on leaves of Oxycoccus palustris and Andromeda polifolia.
http://www.ascofrance.com/search_forum/22363
Another species - Physalospora hyperborea was found regularly in the same place. I thought about Phomatospora clarae-bonae as well, because there is some whitish spots surrounding apical wart, but finally decided that P. hyperborea fits better. There could be mistake..
On fallen leaves of Andromeda polifolia, Oxycoccus palustris.
Perithecia globose, submerged under epidermis with protruding at the surface apical wart, scattered or several nearby in groups at both sides of the leaf. Excipulum of lower part from brownish rectangular cells 20–30 mk in diameter, apical wart from darker small cells; asci cylindrical, short-stipitate, becoming broader with age, with refractive ring, 130–150 x 18.3–20.8 mk; paraphyses abundant, cylindrical, segmented with constrictions, about 5 mk broad; ascospores ellipsoid, with many medium oil guttules, surrounded by thin gelatinous coat, measured in vital state 20.3 (16.8–22.2) x 7 (6.2–8.1) mk (n=30).
Ascomata spherical, submerged under epidermis, with emerging upper wart, without setae, about 370 mk in diameter; scattered on upper leaf side. Asci clavate, with short stalk, bitunicate, 122–150 x 24–32 mk; paraphysoid tissue abundant, threads about 3–5 mk broad; ascospores obovate, filled with small oil guttules, with thin gelatinous coating, 23.3 (20.4–27) x 12 (10.8–13.8) mk (n=17).
