Chers amis d'Ascofrance , voici une très bonne no
Hi everybody,I found this Chaetosphaeria? species on wet, decidious wood, maybe Alnus. Perithecia 0,25 mm wide, superficial, closely packed. ascospores hyaline, (20-24) 22*4,6 (4-5) µm, with high oil content, becoming 3-septate and developing sidespores (4*1,5 µm), hyaline, partly allantoid with two oil-drops, one at each end. Asci 98*7 µm, IKL negative.
Among the perethecia was an anamorph species, with long neck (up to 1450*90 µm, apikal 20 µm), which consists of long, parallel, light grey hyphae, 2,5 µm wide. The conidia are hyaline, ovoid (3-4*2 µm). Maybe the anamorph is a Hyalopycnis. I don't know, if this anamorph-type belongs to Chaetosphaeria.
Regards, Maren
But to be 100% sure you need the anamorph (in this case Menispora caesia).
Eduard
thank you very much, I've checked the key and the description, it might be C. pulviscula. But without the anamorph it get's a cf-mark of me.
I'm still trying to grow the Anamorph, let's see if that succeeds.
Regards, Maren
