Ophiognomonia nana

Ophiognomonia nana ?

Collected on dead leaves of Betula nana (in bog), 20.08.2012.


The genus was identified with Munk (1957), the species by host (SMML DB), and compared with description in Sogonov (2008).


Perithecia spherical with long necks, to 0,5 mm in diameter, immersed in leaf tissue, necks protruding at the surface, to 1 mm long.
Asci spherical, with short stalk and truncate tip, near 25 x 13 mk; spores fusoid-ellipsoid, 1-celled, with acute ends, 12 (11-12,6) x 5 (4,7-5,4) (N=20).


On this subject, i am lacking these two works, may be anybody can share them with me:


Eriksson, O.E. 1992. The non-lichenized pyrenomycetes of Sweden. Btjtryck, Lund, Sweden, 208 pages.
Monod, M. 1983. Monographie taxonomique des Gnomoniaceae (Ascomycetes de l'ordre des Diaporthales). I. Beih. Sydowia 9: 1-315.?

Re : Ophiognomonia nana
Hi,

Only one Gnomoniella is known on Betula leaves : G. nana.
 But your ascospores are slightly too long. But what could be else ?
Yes, Sogonov and al. have combined it, and it's a little surprising but scientifical, in Ophiognomonia.

PS : Chris has been too quick for the doc :)

Hi Chris, and hi all,
I'd be interested in Monod's monography also.
