Leptosphaeria ?
Garcia Susana, 14-03-2016 11:58
Hi,

I found this ascomycete growing in sheet of Platanus.
Pseudotecios are inmersed, with a size of 150 um in diameter, and with a small neck about 40um.
Spores with 5 SEPTA.
I think it is Leptosphaeria, but I could not determine the species.
Any idea?


Thanks, greeting


Susana

Re : Leptosphaeria ?
Oh, strange. The spores make me think of Phaeosphaeria (Leptosphaeria p.p.) vagans, but that species is only noted on monocots, and only Poaceae.

Either there's some weed leaf coming along with the Platanus leaf, and sticked on it, otherwise I have no clue.
Or maybe someone with more knowledge will find the solution...

Cheers - LUC.

Re : Leptosphaeria ?
Hola Luc

No, there was no grass stuck to the sheet. The species was immersed in platanus leaf. The sheet had many "black spots", the majority belonged to Pleospora herbarum. I found 2 perithecia of this type.
To be P. vagans should have spores with some longitudinal septum, and I not saw it. In any case, it would seem more to P. nigrans, but here the spores are greater.
