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.
