Treatment

Rhizoctonia ochracea (Massee) Oberw. et al. View in CoL , Mycol. Progr. 12 (4): 775. 2013.

Basionym: Coniophora ochracea Massee, J. Linn. Soc., Bot. 25 (no. 170): 137. 1889.

Synonyms: Uthatobasidium ochraceum (Massee) Donk, Fungus, Wageningen View in CoL 28: 23. 1958.

Thanatephorus orchidicola Warcup & P.H.B. Talbot, Trans. Brit. Mycol. Soc. View in CoL 49 (3): 432. 1966.

Type citation: ‘(Pl. XLVII. f.13.) (Type in Herb. Kew.) Spreading continuously over the inside of elm-bark which had become slightly separated from the wood of a prostrate trunk. England (Kew).’ Roberts (1999) cites ‘ G. Massee, K’ as holotype, but notes that, according to Donk (1958), the specimen is missing.

Notes: The synonymy of Th. orchidicola , described from England from roots of Orchis mascula , follows Roberts (1999). Given that another of the species listed by Roberts (1999) under Thanatephorus ochraceus (i.e. Th. pennatus ) appears to be distinct, it would be of interest to revisit the placement of Th. orchidicola by attempting to generate sequences from type material.
