Hi friends,

and again, there is an interesting pleosporaleous species growin on dead Clematis stems with distinct setae on the black, hemisphaerical pseudothecia and clavate, 7-8 septated ascospores, which have indistinct, hyaline appendages on both endings (upper ending with hemisphaerical, lower one with conical appendage).

Spores are 25-31x8-10µm, asci 100-130x15-20µm, short stalked and biseriate. I have also found conidial state of very small, beaked conidiomata with Stemphylium-like conidiospores of 14-19x7-9µm.

After comparing several species with Wehmeyer, I have the idea of Pleospora dura, which has tomentose hairs instead of the stiff setae I have recorded. Probably you can tell me something about the relation in Pleospora with their conidial states. In Wehmeyer 1961, P. herbarum is described as attended by Stemphylium state.

I think its time to read Wehmeyer's works...Pleospora is still undeterminable for me :(

[NFF = anamorph, HFF = teleomorph]

Thanks to everyone who can tell me something about it.

regards,
