hard work....Clematis and 3 pyrenomycetes
Björn Wergen, 09-04-2011 01:41
Björn WergenHi again,

"Mycology is to see a whole micro-universe in each small black point in the nature"...mycology is FASCINATING!!

Hmm I had 5 new pyrenomycetes (= small black points) today, and perhaps you can give me some hints for the determination. I have a clear position by all five species, but perhaps someone has another idea. I just give you the photos with some important information, if there is a full description needed, tell me, it will follow on monday.

ON CLEMATIS VITALBA:
species n. 1 is perhaps Pleospora herbarum with very impressive spores
species n. 2 is perhaps Pleospora vitalbae with smaller spores, macrophoto will follow
species n. 3 is perhaps Lophiostoma caulium with very long apices and spores with 3-5 septations

regards and thanks for help,
Kazuya
