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 : 301

Rhizoctonia anomala (Currah) R.P. O’Donnell, C.C. Linde & T.W. May, comb. nov. MB 852043 .

Basionym: Moniliopsis anomala Currah, Canad. J. Bot. 68 (6): 1180. 1990.

Synonym: ‘ Rhizoctonia anomala ’ Burgeff, Samenkeim. Orch. : 132. 1936. nom. inval. ( Table 3)

Type citation: ‘ Neotype a dried colony of UAMH 6451 on CMA, ex C. viride, Cardinal River Divide.’ Given that the name was being newly described by Currah, the designation as “ neotype ” should be corrected to “ holotype ”.

ITS barcode: ITS 1 = KF267003 ( T); ITS 2 = KF267040 ( T). UNITE 1.5 % SH: n/a.

Alternative marker: LSU = KF267077 ( T).

Ex-type culture: CBS 193.90.

Notes: Currah et al. (1990) introduced the name ‘ Moniliopsis anomala Burgeff ex Currah , sp. nov. ’ accompanied by a description and citation of a ‘neotype’. According to Art. 46.4, the name should be attributed to Currah alone, even though it was an attempt to validate ‘ Rhizoctonia anomala Burgeff’, because Burgeff’s name was introduced in a different genus. Even though the name R. anomal a has been used in the literature, it is not valid. Therefore, we here create the valid combination R. anomala by formalising the transfer of M. anomala to Rhizoctonia .
