Genera in Bionectriaceae, Hypocreaceae, and Nectriaceae (Hypocreales) proposed for acceptance or rejection

Abstract

With the recent changes concerning pleomorphic fungi in the new International Code of Nomenclature for algae, fungi, and plants (ICN), it is necessary to propose the acceptance or protection of sexual morph-typified or asexual morph-typified generic names that do not have priority, or to propose the rejection or suppression1 of competing names. In addition, sexual morph-typified generic names, where widely used, must be proposed for rejection or suppression in favour of asexual morph-typified names that have priority, or the latter must be proposed for conservation or protection. Some pragmatic criteria used for deciding the acceptance or rejection of generic names include: the number of name changes required when one generic name is used over another, the clarity of the generic concept, their relative frequencies of use in the scientific literature, and a vote of interested mycologists. Here, twelve widely used generic names in three families of Hypocreales are proposed for acceptance, either by conservation or protection, despite their lack of priority of publication, or because they are widely used asexual morph-typified names. Each pair of generic names is evaluated, with a recommendation as to the generic name to be used, and safeguarded, either through conservation or protection. Four generic names typified by a species with a sexual morph as type that are younger than competing generic names typified by a species with an asexual morph type, are proposed for use. Eight older generic names typified by species with an asexual morph as type are proposed for use over younger competing generic names typified by a species with a sexual morph as type. Within Bionectriaceae, Clonostachys is recommended over Bionectria; in Hypocreaceae, Hypomyces is recommended over Cladobotryum, Sphaerostilbella over Gliocladium, and Trichoderma over Hypocrea; and in Nectriaceae, Actinostilbe is recommended over Lanatonectria, Cylindrocladiella over Nectricladiella, Fusarium over Gibberella, Gliocephalotrichum over Leuconectria, Gliocladiopsis over Glionectria, Nalanthamala over Rubrinectria, Nectria over Tubercularia, and Neonectria over Cylindrocarpon.

“…), and almost identical "H-NMR spectra. The differences found in the polysaccharide from N. cinnabarina and species of Sesquicillium and Nectria with Sesquicillium anamorphs were in agreement with the separation of these species according to their morphological characters (Samuels and Rossman, 1979) and support the creation of the genus Bionectria (Rossman et al, 1999).…”

Relación in vitro entre Cylindrocarpon cylindroides y Neonectria fuckeliana asociados a cancros fustales de Pinus radiata en Chile

“…tenue como anamorfo de Neonectria fuckeliana, lo que está en concordancia con lo señalado por Castelbury et al (2006) al proponer el cambio de la especie Nectria fuckeliana al actual género Neonectria. Estos resultados son concordantes también con la relación Neonectria/ Cylindrocarpon, delimitada en sentido estricto por Chaverri et al (2011) y reconocida luego por Rossman et al (2013).…”

Scientific Opinion on the maintenance of the list of QPS biological agents intentionally added to food and feed (2013 update)

“…In light of the recent change in nomenclatural rules the genus Clonostachys is proposed to be protected against Gliocladium and Bionectria (Rossman et al, 2013). No information on lack of toxins or toxicity against mammals is reported, therefore this species cannot be proposed for the QPS list.…”

“…These endeavours do not have any impact on taxonomic designations of species notified to EFSA. In light of the one name nomenclature for fungi it is proposed to protect the use of Trichoderma against Hypocrea (Rossman et al, 2013). …”
