Pyrenomycete on Fagus
Steve Clements, 07-06-2015 23:15
Hi,
This stromatic pyrenomycete was found on a beech Fagus sylvatica) log, 3/6/15. It was about 30 cm long. The "crust" was very rough, up to 2mm thick, with the perithecia immersed. Perithecia were approximately 0.75 x 0.5 mm, and could be easily detached from the stroma. Asci were 70-75 um long and 6 wide. They contained 8 spores, untidily packed in the apex. The apical disc stained blue in Lugol, size approximately 1.5 x 0.5 um. Spores were dropped in small numbers, these were hyaline, 7-10 x 2-2.5 with two or more guttules, slightly curved. Similar spores were also seen within the asci. Some conidia were also found on the slide. Paraphyses? were very long, to 150 x 2. I am finding identification of this easily spotted Pyrenomycete rather difficult. Could anyone help me out please?
Best regards,
Steve

Bonjours,
Cette pyrenomycete stromatiques été trouvé sur une bûche de Fagus sylvatica, 06/03/15. Il était environ 30 cm de long. Le "croûte" était très rêche, jusqu'à 2 mm d'épaisseur, avec les périthèces immergés. Périthèces ont été d'environ 0,75 x 0,5 mm, et pourrait être facilement détaché du stroma. Asques étaient 70-75 um de long et 6 de large. Ils contenaient 8 spores, emballés en désordre dans l'apex. Le disque apical teinté bleu dans Lugol, la taille d'environ 1,5 x 0,5 um. Les spores ont libérés en petit nombre -hyaline, 7-10 x 2-2,5 avec deux ou plusieurs guttules, un peu incurvé. Spores similaires ont également été observés dans les asques. J'ai aussi trouvé des conidies?. Paraphyses (peut-être) étaient très longues, à 150 x 2. Je trouve l'identification de cette facilement repéré Pyrenomycete plutôt difficile. Aidez-moi s'il vous plaît!
Cordialement,
Steve

Re : Pyrenomycete on Fagus

Hello,


that was my immediate thought too.


Rough surface and large stromata as well as the microscopical details shown qould fit perfect.


best regards,


Andreas

Re : Pyrenomycete on Fagus
Many thanks,
This is obviously rather eroded! John and I identified this previous specimen from Longshaw Estate easily enough,
Best wishes,
