Ascomycetes described from Freycinetia

Abstract

Sixteen species of ascomycetes with their type specimens recorded from Freycinetia are re-examined and their taxonomic positions considered. Ellisiodothis microdisca, Melanochaeta aotearoae, Mycosphaerella freycinetiae, Nectria freycinetiae, Nectriopsis squamulosa, Phyllachora freycinetiae and Stictis subiculata are considered correctly placed, Hugueninia freycinetiae, Guignardia freycinetiae, Hypoxylon freycinetiae and Seynesia atkinsonii are transferred to other genera. Auerswaldia merrillii, Clypeosphaeria stevensii, Metasphaeria christophersenii, Peltella freycinetiae and Pyrenocyclus ambiguus are considered ambiguous species. Finally, Pyrenula sp. is described and illustrated. Each accepted species is redescribed and illustrated with light micrographs.
