Niesslia exosporioides ?
Dragiša Savic, 23-05-2016 13:03
Hello everyone,
I found this Niesslia species on dead petiole of Petasites hybridus.
Does anyone has a key for the species in the genus Niesslia?

Re : Niesslia exosporioides ?
Dear Dragisa.

I am working on a monograph of Niesslia and am very interested in your material. There is no recent key to the species of the genus except the one in my manuscript. I would thus be very happy to help you. Please send it to me at Molenweg 15,, NL-3743 CK Baarn, Netherlands.
