Treatment

Rhizoctonia klebahnii (G. Burchard) R.P. O’Donnell, C.C. Linde & T.W. May, comb. nov. MB 852069 View Materials .

Basionym: Moniliopsis klebahnii View in CoL G. Burchard Phytopathol. Z. 1: 277. 1929, as ‘ klebahni ’.

Synonym: Ceratobasidium albasitensis V. González & V. Rubio View in CoL , Persoonia View in CoL 17 (4): 603. 2002.

Type citation: ‘Ich möchte dem Pilz, im Hinblick auf die Verdienste Herrn Prof. Klebahns um die Erforschung der Kiefernschädlinge überhaupt, und da er den Pilz zuerst in Kultur zog, den Namen Moniliopsis klebahni geben.’ [ I would like to give to the fungus, in view of Prof. Klebahn’s achievements in researching pine pests in general, and since he was the first to grow the fungus in culture, the name Moniliopsis klebahni .’]

ITS barcode: MH854971 View Materials ( R).

UNITE 1.5 % SH: SH0897862.10FU.

Notes: BLAST results show that the sequence of M. klebahnii used in this study (GenBank MH854971 View Materials ) generated by Vu et al. (2019) which is cited as being sequenced from an authentic isolate produced by G. Burchard – the author of M. klebahnii – is 99–100 % identical with several accessions of Cb. albasitensis published by González et al. (2002), including the ex-type sequence of Cb. albasitensis used in this study (GenBank AJ242875 View Materials ). These two accessions are placed together in the UNITE 1.5 % SH SH0897862.10FU. Sequences from the 1.5 % SH come from a wide geographic range and from a wide variety of hosts, but we note that M. klebahnii and Cb. albasitensis are both stated to be pine pathogens in their respective protologues. Due to the high identity between reference sequences of both Moniliopsis klebahnii and Cb. albasitensis , they should be considered synonymous. As M. klebahnii (1929) predates the publication of Cb. albasitensis (2002), the epithet klebahnii takes priority.
