Hi there,here is another problem, found in Austria on dead dicot stems. I hadn't ever seen any Lasiosphaeria species with so long, straight hairs, which are up to 310µm long.
Spores sometimes have 1 (perhaps 2) septation.
With the key available on the page I come to L. rufa (without setae septations) or L. caudata (spores are bigger).
Any idea?
regards,
björn

Re : Lasiosphaeria
This is Hilberina rufa.
Ascomata gregarious to densely crowded, globose to ovoid, 380-480 µm diam. x 480-550 µm high, setae pale reddish-brown, thick-walled with narrow lumen, blunt to acute ended; ascospores cylindrical, basal end curved in obtuse angle, attenuate and acerose with a slightly swollen enlarged tip, hyaline to yellowish, 3-septate, 48-58 x 3.5-3.8 µm

Re : Lasiosphaeria
Hi Andy,
it is really L. rufa? Ok, I thought this species has to have non-septated hairs. Many thanks for your help :)

Re : Lasiosphaeria
Sorry, I was beta testing a new key I'm trying to make for these things and it still needs some work (obviously). Â This is probably Hilberina caudata although you said the spores were longer in your collection.

Re : Lasiosphaeria
Hi,
I think that the spores of H. caudata are longer as in my collection (that was what I meant). For me, Hilberina rufa seems to fit better (compared with H. caudata).

Re : Lasiosphaeria
But, your spores look very different from what Candousau et al. illustrated for L. rufa.
