interesting Lophiostoma on Fagus
Björn Wergen, 15-04-2012 18:31
Björn WergenHi all,

I have found a very interesting lophiostomoid fungus growing on decorticated Fagus branch. It has small 0,3-0,6 mm broad perithecia with a typical lophiostoma-ostiolus. Spores are 24-29x4-4,5µm, first with a medium single septa, then with 3-4 septations, hyalin, mature spores very pale brown, with a distinct hyaline sheath surrounding a whole spore and acute endings. 
Asci 70-100x6-8µm, with 8 +/- biseriate spores.

Substrate: Fagus (or Quercus, but I think it was Fagus, decorticated at all).

What can this be? I have tried Chesters&Bell and Barr, watched some photos made by Alain and so on, but there is no matching species. Macroscopically Navicella pileata is similar, but it has very different spores...

I hate mycology...sometimes :D

regards,
björn

Re : interesting Lophiostoma on Fagus
Hi Bjorn,
It looks like Lophiotrema neohysterioides, but ascospores of this species are given without sheath.  And your one seems to have a L/l more important.  Perhaps more closed to Lophiostoma vigheffulensis ? Else, Ive no idea.
Good research !

Re : interesting Lophiostoma on Fagus
Hi Alain,

I have the same name on my list: L. vigheffulensis (between L. vigheffulensis and L. winteri). But the sheath is something very strange for this genus, isn't it? 

Thanks a lot.

regards,
björn
