Crocicreas dolosellum ?
Gilles Corriol, 28-04-2013 17:04
Gilles CorriolBonjour,

Voici une récolte de l'an dernier (GC12112210), étudiée avec réactifs non orthodoxes ...
Sur tige herbacée.

Spores étroitement fusiformes 13,1-18,2 x 2,2-2,8 µm, 0-1 septées, faiblement guttulées.
Asques environ 70x7 µm, 8 sp., bisériés, bouclés, I+ (au fait, un asque ou une asque en français ?)
Paraphyses cylindriques, x 2-2,5 µm, non ramifiées, non septées.
Trame à hyphes allongées, gélifiées.
Poils externes cylindriques, à contenu granuleux, jaune d'or.

Merci pour vos critiques et avis !

Re : Crocicreas dolosellum ?
Can you exclude Fraxinus petioles? Because the features remind me of Cyathicula fraxinophila.

C. dolosella has 1-septate spores already inside the living asci, C. fraxinophila only outside or in dead asci.

C. fraxinophila has croziers, my C. dolosella (5188) not.

Re : Crocicreas dolosellum ?
Substrate is likely to be Fraxinus excelsior petiole. Only very few mature spores were septed. C. fraxinophilus seems a very good candidate.
It seems that spores also were too long for C. dolosellum.

Thank you Zotto.

Re : Crocicreas dolosellum ?
Frax petioles you can easily recognize by their scars (two at each internodium) where the leaftes emerged.

Re : Crocicreas dolosellum ?
I confirm there are such scars.
