"Rhytisma urticae"
Alex Akulov, 12-07-2011 21:02
Alex AkulovDear Friends 
Sufficiently long time ago in L. Fuckel exiccati I watched the sample of Rhytisma urticae on overwintered Urtica dioica stems. Recently, I've collected in the Carpathians very similar sample. Using the Internet, I found that the modern name of this species - Aporhytisma urticae with anamorph Apomelasmia urticae. Unfortunately, the available information about this species is too poor. 

In my sample I found conidia, which are similar to Melasmia representative and other type of spores also.

I have no literature to solve problems with the collected sample. If someone could send me a description of Aporhytisma urticae, as well as express your opinion about this sample, I would be very grateful!

Re : "Rhytisma urticae"
Dear Friends
Today I received a response from Dave Minter with more in detailed datas about this species. He wrote:
Aporhytisma urticae is not so easy. It's not in Dennis (British Ascomycetes) and it's not in the Ascomycetes volume of Champignons de Suisse. Petrak wrote about it in Sydowia 24: 252 (available from Cyberliber). Arx & Muller in Beitrage zur Kryptfl. Schweiz 11: 373 (available from Cyberliber) redisposed it as Diaporthopsis = Diaporthe. There's a photograph of A. urticae on the Internet [http://www.fundkorb.de/?Fundkorb:Acrospermum_compressum%26nbsp%3B_Tode%3AFr.] which looks rather like your fungus.

Please, see also attached files - pages from Sutton's Coelomycetes (1980), with description and illustration of anamorph.
