Synnemata on herbaceous stem
Stefan Blaser, 31-07-2013 09:13
Hello everybody

I'm trying to identify these rather conspicuous synnematous Hyphomycetes. Does anybody have a hint for a Genus or even a Species?


Habitat: On dead herbaceous stem (probably Adenostyles)


Description: Synnemata with a black Stipe and a brownish head (somewhat slimy when wet, consisting of conidia in chains). Size 1.5-2 x 0.5 mm.


The conidia are produced in long, branched chains (>100 µm long). Single conidial cells usually 8-9 x 2-2.5 µm, hyaline. Few single conidia visible.


Thanks a lot for any comments


Stefan

Re : Synnemata on herbaceous stem
Cher Collègue,

Il s'agit de la forme conidienne Heteropatella Fuckel. Sur Adenostyles, croit le teleomorphe Heterospaeria compositarum (Rehm) Hönel.

Re : Synnemata on herbaceous stem
Cher René

Merci bien pour cet identification vite. A "Swissfungi" Il y a deux entrées pour Heterosphaeria compositarum et pour H. lojkae. Mais c'es synonyme, n'est ce pas?

Cordialement
Stefan
