The genus Aciculosporium (Clavicipitaceae, Hypocreales, Ascomycota) was established in 1908 for A. take, which is the causal fungus of witches’ broom of bamboo. Although the original description was valid at that time, a type specimen for A. take has not been designated. To standardize the use of this genus and species name, a neotypification and reference specimen of A. take is are proposed. Multilocus phylogenetic analyses based on DNA sequences from 28S rDNA, TEF, Tub2, Mcm7, and RPB2 revealed that A. sasicola is from a different lineage to A. take, and other material specimens from wavyleaf basket grass (Oplismenus undulatifolius) represent a distinct species proposed here as Aciculosporium oplismeni sp. nov. Chemical analysis using mass spectrometry and nuclear magnetic resonance spectroscopy, etc. showed that A. take produces four proline-containing cyclic dipeptides, which are moieties of ergot alkaloids, . although However, ergot alkaloids, lolines, peramine, indole-diterpenes, and lolitrem were not detected in the culture solvent. The presentis study offers clarification of the lineage and morphology of this genus.
