Leptosphaeria species on platanus

Ralph Vandiest, 24-02-2014 23:09

Hello,

I found this species on platanus. Looks like Leptosphaeria species but not sure (as the only possible fit with my key is J galii?!). 0,3/0,4mm diam wide, in large clusters, asci 8-sporig up to 100µm, 3-sepated, incurved spores
13/16x4/5µm, outher cells wider than inner cells.

Can anybody help me with this?

regards,

Ralph
