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.

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

“…These are also useful sources for validity of published names. There is an ongoing debate among mycologists to protect or preserve names Hibbett and Taylor, 2013;Rossman et al, 2013). For practical identification of fungi a DNA barcode initiative has been launched (Schoch et al, 2012;Blaalid et al, 2013).…”

“…If such an approach will reduce confusion arising from dual nomenclature system relating to pleomorphism in fungi (Wingfield et al, 2012), it raises the issue of 'one fungus, which name?'. In recent publications Rossman et al, 2013), the impact of these new systematic rules for the Fusarium genus is discussed.…”

“…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). …”

Caracterización y control de Cylindrocarpon SPP.agente causal del pie negro de la vid.

“…De esta manera, todos los representantes de Nectria con forma asexual Cylindrocarpon spp., fueron transferidos a uno de estos nuevos géneros denominado Neonectria Wollenw. La correspondencia Neonectria-Cylindrocarpon fue corroborada mediante estudios filogenéticos, dónde quedo demostrado que Cylindrocarpon y Neonectria son monofiléticos (Rossman et al, 1999;Mantiri et al, 2001;Braydford et al, 2004).…”
