Rhizoctonia australiensis (Y.P. Tan & P. Adhikari) R.P. O’Donnell, C.C. Linde & T.W. May, comb. nov. MB 856690 View Materials .

Basionym: Ceratobasidium australiense Y.P. Tan & P.Adhikari , Index of Australian Fungi 37: 1 2024, as ‘australiensis’.

Type citation: ‘ Australia, Queensland, Bundaberg, from root lesion of Saccharum officinarum ( Poaceae ), 2019, P. Adhikari ( holotype BRIP 73022 a permanently preserved in a metabolically inactive state).’

ITS barcode: PP794647 ( T).

UNITE 1.5 % SH: n/a.

Notes: A BLAST search of the type accession of R. australiensis found that it is similar to accessions identified as Rhizoctonia AG-Ba, identified here as R. fumigata . However, the type sequence for R. australiensis was found to be only 94.29 % identical with the type sequence of R. fumigata (GenBank FJ231392 View Materials ). As there appears to be substantial divergence between these two accessions, R. australiensis and R. fumigata are best treated as distinct entities.
