Mick PeerdemanHi all,One of my earliest microscopy attempts, so
This gnomoniaceae grows abundantly on leaves of Quercus.
Size: 350 - 400 x 280-350um. Neck 900-1300 x 45-50.
Asci: 30-33 x 9-13um. Apical apparatus 2um
Spores: 13-15 x 2-3um, noncentral septum (60% -40%). With small appendages (2-3um) at the ends.
Initially I thought it was Ophiognomonia setacea, but lacks the central septum. It looks like gnomnia incrassata, but the neck is long and slightly smaller spores, and the host is Quercus.
Do not know whose it is?
Can anyone identify the species?
Thanks in advance
Susana (Spain)?
Very good !
Alain
Thank you, Alain!
Gracias Enrique, pero creo que no es dificil encontrarla, de hecho, he recogido al azar hojas de roble (en bosque mixto con pino) en lugares distintos y en casi todas estaba presente (comprobando al micro). Esto es en Sarasibar (Navarra), una zona que creo ya has visitado.
Saludos.
Susana
Gracias Susana
Hi spanish friends,
Last week, I have collected easily this Gnomonia. Same features, and I also can note appendages, feature not seen in swissen collections.
It should be G. kisslingii. But I send it to Donny Walker in order to have its molecular sequency.
Best wishes,
Alain
J'ai aussi trouvé cette espèce , cependant, je lis dans la monographie de Monod que les spores sont dépourvues d'appendices .
Y a t il eu confirmation ultérieurement à sa publication que G. kisslingii a bien des appendices ?
Amitiés
Michel
Rien de neuf depuis cette mointaine époque. Donald avait arrêté les Gnomoniaceae. Le sujet mériterait d'être creusé.
