Mitosporic fungus. Hyphomycetes.
Approx. 20 species.
Soil, blackened and dead herbaceous stems and leaf spots, grasses, rushes and sedges. Almost always associated with other fungi.
Rarely found growing indoors.
Rare case of mycotic keratitis reported.
Colonial morphology is similar to Cladosporium. Periconia is infrequently isolated in culture.
Some species have distinguishing spore characteristics and are recognizable. Generally it is difficult to distinguish Periconia spores from the smuts, myxomycetes and other round, brown spore types.
Spores with underlying sporulating structures are distinctive, although we very rarely see them on tape lifts.
