O’Donnell, R. P., Linde, C. C. & May, T. W., 2025, Rise up, Rhizoctonia: moving to one fungus, one name in the Ceratobasidiaceae (Agaricomycetes, Cantharellales), Persoonia 54 (1), pp. 285-325 : 311

Rhizoctonia queenslandica (Y.P. Tan & P. Adhikari) R.P. O’Donnell, C.C. Linde & T.W. May, comb. nov. MB 856695 . Basionym: Ceratobasidium queenslandicum Y.P. Tan & P. Adhikari , Index of Australian Fungi 37: 2. 2024.

Type citation: ‘ Australia, Queensland, Jimbour, from root lesion of Saccharum officinarum ( Poaceae ), 2019, P. Adhikari (holotype BRIP 73024a permanently preserved in a metabolically inactive state).’

ITS barcode: PP794648 ( T).

UNITE 1.5 % SH: n/a.

Notes: BLAST searches of the ITS type accession found that R. queenslandica is more than 97.8 % identical with some accessions identified as Ceratobasidium AG-B(o) as identified by Sharon et al. (2008: e.g. GenBank AB219143 at 98.4 %). For this reason, R. queenslandica should be considered the epithet associated with this AG group. Note that according to Sharon et al. (2008) some isolates originally identified as AG-B(o), for example SIR-2 (ITS sequence GenBank AF354091 ) as included in Gónzalez et al. (2001), belong instead to other AG groups. SIR-2 was placed in AG-A by Gónzalez et al. (2016).
