Abstract

The lichenicolous coelomycete Stromatopogon baldwinii., forming galls on Usnea inTasmania and the Sandwich Islands, has a type of conidiogenesis not previously recognized amongst lichenized and lichenicolous fungi. Two different types of conidia, small simple microconidia and large submuriform macroconidia, are produced in the same conidioma, but in different regionsof the inner conidiomatal wall. The same kind of cells of the conidiomatal wall act as conidiogenous cells when macroconidia are produced, or give rise to elongated ramified conidiophoreswhen microconidia are produced.
