Pycnoporus coccineus (Fr.) Bondartsev & Singer (1941: 59)

≡ Polyporus coccineus Fries (1851 [1855]: 67) ≡ Fomes coccineus (Fr.) Cooke (1885: 21) ≡ Scindalma coccineum (Fr.) Kuntze (1898: 518) . Mycobank no.: MB 304884. Lectotype (designated here):—POLYNESIA. Marquesas Islands: Motu Iti, s.d., Behm s.n. (K(M) 164023!).

Notes:— Bondartsev & Singer (1941) described Pycnoporus coccineus based on Polyporus coccineus Fr. the basionym. Fries (1851) published the name Po. coccineus , referencing a specimen collected from Motu Iti in the Marquesas Islands and citing “legitimate Prof. Behm”, and a specimen from Didrichsen (no. 34), but he did not indicate where the specimen was deposited, nor did he cite a type. Lloyd (1916) confirmed that the type specimen of Po. coccineus disappeared from Fries’ herbarium. We searched the herbaria in which Fries’ collections were deposited and located material at KEW. Lloyd (1916) cited material deposited at KEW, possibly the same material that we found, and referred to it as a “cotype” referring to Po. coccineus (see note 440), which may indicate the existence of more than one specimen. Thus, in accordance with Art. 9.12 (ICN, Turland et al. 2018), we designate the specimen deposited at KEW (K(M) 164023) as a lectotype of Pycnoporus coccineus ( Fig. 1B ). The specimen information reports a collection by “Prof. Behm.”, which corroborates the protologue of Po. coccineus and was identified as “ Polypori coccinei ”.
