Several unidentified specimens of Curvularia deposited in the Queensland Plant Pathology Herbarium were re-examined. Phylogenetic analyses based on sequence data of the internal transcribed spacer region, partial fragments of the glyceraldehyde-3-phosphate dehydrogenase and the translation elongation factor 1-α genes, supported the introduction of 13 novel Curvularia species. Eight of the species described, namely, C.
beasleyi
sp. nov., C.
beerburrumensis
sp. nov., C.
eragrosticola
sp. nov., C.
kenpeggii
sp. nov., C.
mebaldsii
sp. nov., C.
petersonii
sp. nov., C.
platzii
sp. nov. and C.
warraberensis
sp. nov., were isolated from grasses (Poaceae) exotic to Australia. Only two species, C.
lamingtonensis
sp. nov. and C.
sporobolicola
sp. nov., were described from native Australian grasses. Two species were described from hosts in other families, namely, C.
coatesiae
sp. nov. from Litchi
chinensis (Sapindaceae) and C.
colbranii
sp. nov. from Crinum
zeylanicum (Amaryllidaceae). Curvularia
reesii
sp. nov. was described from an isolate obtained from an air sample. Furthermore, DNA sequences from ex-type cultures supported the generic placement of C.
neoindica and the transfer of Drechslera
boeremae to Curvularia.
