CHAPTER VIII. Names of anamorphic fungi or fungi with a pleomorphic life cycle
A name published prior to 1 January 2013 for a taxon of non-lichen-forming Ascomycota and Basidiomycota, with the intent or implied intent of applying to or being typified by one particular morph (e.g. anamorph or teleomorph), may be legitimate even if it otherwise would be illegitimate under Art. 52 on account of the protologue including a type (as defined in Art. 52.2) referable to a different morph. If the name is otherwise legitimate, it competes for priority (Art. 11.3 and 11.4; see also Art. 57.2).
Penicillium brefeldianum B. O. Dodge (1933) was described and based on a type with both the anamorph and teleomorph (and therefore necessarily typified by the teleomorph element alone under previous editions of this Code). The combination Eupenicillium brefeldianum (B. O. Dodge) Stolk & D. B. Scott (1967) for the teleomorph is legitimate. Penicillium dodgei Pitt (1980), typified by the anamorph in a dried culture “derived from Dodge’s type”, did not include the teleomorphic type of P. brefeldianum and therefore it too is legitimate. However, when considered a species of Penicillium, the correct name for all its states is P. brefeldianum.
Except as provided in Art. 59.1, names of fungi with mitotic asexual morphs (anamorphs) as well as a meiotic sexual morph (teleomorph) must conform to the same provisions of this Code as all other fungi.
Previous editions of this Code provided for separate names for mitotic asexual morphs (anamorphs) of certain pleomorphic fungi and required that the name applicable to the whole fungus be typified by a meiotic sexual morph (teleomorph). Under the current Code, however, all legitimate fungal names are treated equally for the purposes of establishing priority, regardless of the life history stage of the type (but see Art. 57.2; see also Art. 14.13).
Mycosphaerella aleuritidis (Miyake) S. H. Ou (1940), when published as a new combination, was accompanied by a Latin diagnosis of the newly discovered teleomorph corresponding to the anamorph on which the basionym Cercosporaaleuritidis Miyake (1912) was typified. Under previous editions of this Code,M. aleuritidis was considered to be the name of a new species with a teleomorph type, dating from 1940, and with authorship attributed solely to Ou. Under the current Code, the name is cited as originally published, M. aleuritidis (Miyake) S. H. Ou, and is typified by the type of the basionym.
In the protologue of the teleomorph-typified Venturia acerina Plakidas ex M. E. Barr (1968) the anamorph-typified Cladosporium humile Davis (1919) was included as a synonym. The name V. acerina is not illegitimate as it was published prior to 1 January 2013, but C. humile is the earliest legitimate name at the rank of species.
Names proposed simultaneously for separate morphs (e.g. anamorph and teleomorph) of a taxon of non-lichen-forming Ascomycota and Basidiomycota are necessarily heterotypic and are not therefore alternative names as defined by Art. 36.2.
Hypocrea dorotheae Samuels & Dodd and Trichoderma dorotheae Samuels & Dodd were simultaneously validly published (in Stud. Mycol. 56: 112. 2006) for what the authors considered a single species with PDD 83839 as the holotype. As these names were published before 1 January 2013 (see Art. 59.1 and Note 2), and as the authors explicitly indicated that the name T. dorotheae was typified by the anamorphic element of PDD 83839, both names are validly published and legitimate. They are not alternative names as defined in Art. 36.2.
