Specimen notes
Public Note:
purple raised blotches, hyaline tendrils. Conidia hyaline 20-40 x 1.5-2um. Careful plating of tendrils from spots produced two very different isolates. One the hyaline cladosporium-like Ramulari euclaypti (presumably) and the other a clear septoria (not phaeophloespora). Tendrils white not green. Peter J examined the type of S. coprosmae and thought it a Moellerodiscus. However this collection and CBS113391 (New Zealand, North Island, Bay of Islands area, near Russell, Verkeley - originally misidentified as Mycosphaerella coacervata) probably indicate a good species.Cooke has conidia 30 x 2um. It seems there are two common leaf spots on Coprosma. The Phaeophleospora-like has green tendrils and short conidia and the Septoria hyaline tendrils and long conidia. In addition there is a cryptic Ramularia euclaypti which is commonly (!) isolated and is not the same as either. Sydow's Mycosphaerella coacervata is translated in Gadgil except conidia originally 5-6 x 1.5-2.5um (not 5-6 x 3-4um). It seems likely that Sydow is describing a teleomorphic Teratosphareia with a Kirramyces (Phaeophleospora-like) anamorph in his description. This is the one with green tendrils. It also seems likley that the Kirramyces/M. coacervata anamorph is the same as Phyllostica coprosmae from Australia, and it would provide the earliest name. M. coacervata requires a recomination in Kirramyces. Requires a sequence to check if same as CBS isolate (which is same as my Septoria matthiolae with wider condiia). [adjacent isolation plate says S. exotica with no #? and the sequence comes out as S. exotica. Misplaced plate?]
