Leptosphaeria on Tamus communis
Enrique Rubio, 23-05-2018 19:32
Enrique RubioHi again
Minute semi-inmersed pseudothecia (up to 200 microns in diam) with only the obtuse papilla visble, on stems of Tamus communis (Dioscorea c.).
The golden light ascospores are (1-)3-septate, the second cell slightly enlarged, with obscure apical conical appendages. 
It seems to match with the plate 0506 in last Bjorn Bwergen's book on Pyrenomyecetes, under the name Leptosphaeria scitula on Chelidonium. But the spore (and asci) size is larger than Holm and Shoemaker's descriptions.
What do you think?
Thanks again for help me.

Re : Leptosphaeria on Tamus communis
I thing, that this can be Paraleptosphaeria nitschkei, or so something from this agregation. I have collection this species from the Papaver orientale, but most common are collections from Asteraceae. It would be very interesting this your collection sequencing, i should interested in this collection, because I interested in the genus Leptosphaeria and I this genus want to process in detail. 
On Tamus was found only Leptosphaeria tami, but it has shorter hyaline spore (17 x 4,5 um) and 4-septate. P. nitschkei has spore 3-5 septate and 28-36 x 3-4 um large. Your collection has characteristics of morfology of spore for P. nitchkei.
