Systematics of selected foliicolous fungi associated with leaf spots of Proteaceae

The present study treats several fungi associated with leaf spots of Proteaceae from Africa, Australia and India. Leptosphaeria leucadendri (anamorph: Sclerostagonospora leucadendri) is described from Leucadendron leaves from Australia, while three previously described African taxa from Protea leaves are transferred to Phaeophleospora as P. abyssinicae, P. congestum and P. protearum. Trimmatostroma protearum and a Phyllosticta sp. are described from Protea leaves collected in South Africa and Australia, respectively. Cercospora agharkarii, which occurs on Grevillea, is redisposed to Pseudocercopora while a new genus Pseudohendersonia, is proposed for P. proteae occurring on Protea leaves in South Africa.
