Venturia cassandrae (Gibbera cassandrae)

It is common inhabitant of Chamaedaphne leave litter in bogs. My specimen has some smaller spores compared with the description in Barr (1968) 15,5-21 x (4,5)6-9.

Perithecia pear-shaped,  80 x 60 mk; sited at the surface ir partly  immersed, often arising from under epidermal scales; overall brownish, at the narrowed tip darker to black, tip surrounded by sharp, bent bristles; leaf surface with frbs sometimes devided by black lines.
Excipulum from angular cells near  10 mk; bristles straight or bent down, for 45 long, 5 broad at base, sharp; asci fisitunicate, near 30-40 x 10 (unexpanded); spores 2-celled, upper cell wider and shorter, brown, guttulate, 14 (12,5-16) x 4,7 (4,1-5,7) (N=32).
