Re : anamorph on living leaves of Prunus serotina
Hello Riet
These foliicolous fungi with small hyaline unicellular conidia are in a very confused state, with vast numbers of names in Phoma, Phyllosticta etc. created in the past and mostly based on host relationships.
There is a Phyllosticta serotina https://www.biodiversitylibrary.org/page/48300462#page/32/mode/1up
and a Ph. treleasei https://www.biodiversitylibrary.org/page/32874282#page/295/mode/1up
van der Aa comments on the latter - see attached.
When something as distinctive as the Miricatena comes along that is a more hopeful direction ;-)
Sorry can't be of any real help here.
Kind regards, Chris
