Rossman et al. (1999) established the sexual genus Lanatonectria, based on L. ﬂocculenta, for nectriaceous fungi with Actinostilbe asexual morphs. Later, Rossman et al. (2013) proposed that the genus name Lanatonectria be suppressed in favour of Actinostilbe based on priority, as per the ICN (McNiell et al. 2012). However, Sutton (1981) had already synonymised Actinostilbe under the asexual morph genus Sarcopodium. Furthermore, Rossman et al. (2013) synonymised L. ﬂocculenta (= A. macalpinei) under A. ﬂocculenta. Actinostilbe ﬂocculenta should be regarded as a synonym of S. macalpinei as proposed by Sutton (1981). Phylogenetic inference in this study clearly supports the ﬁndings of Sutton (1981). Therefore, we regard Actinostilbe as a synonym of Sarcopodium and introduce several new combinations below.

Dialonectria (Sacc.) Cooke 1884

Notes

Notes: Representatives of the genus Cosmospora formed a well supported clade (BS 75 %, PP 0.95), which also included representatives of the genus Dialonectria (CBS 125493 & CBS 125494; Grafenhan et al. 2011). Samuels et al. (1991) revised the genus Dialonectria (as Nectria subgen. Dialonectria) and assigned it to Cosmospora sensu Rossman. Grafenhan et al. (2011) later resurrected the genus Dialonectria and restricted its generic concept around the type species, D. episphaeria, recognising that this species represents a species complex of at least ﬁve phylogenetic lineages. Although the phylogenetic inference in this study supports the ﬁndings of Samuels et al. (1991) that Dialonectria should be seen as a synonym of Cosmospora, we select not to introduce new combinations at present. A monographic study for both genera is required to stabilise the taxonomy of these genera.

Fusarium Link 1809

Notes

Notes: The genus Fusarium as treated here accommodates Fusarium spp. belonging to the Gibberella clade (O'Donnell et al. 2013). This genus includes many important plant pathogenic and medically important species, and includes various Fusarium species groups, which could result in the segregation of this genus into more genera. However, a monographic study, which includes a more robust phylogeny, is required to identify and introduce these genera. In this study, representatives of this genus formed a well-supported monophyletic clade (BS = 100 %, PP = 1.0) distinct from the clades representing Albonectria, Cyanonectria and Geejayessia. A new combination is required for F. sambucinum (1863), the type species of the genus, as the epithet of Sphaeria pulicaris (1823) is older. However, we refrain from doing so here as F. sambucinum is extensively used in literature and better known among plant pathologists and other applied biologists.

Gliocephalotrichum J.J. Ellis & Hesselt. 1962

Notes

Notes: Species of Gliocephalotrichum are soil-borne fungi generally associated with post-harvest fruit spoilage of several important tropical fruit crops (Lombard et al. 2014a).

Pseudonectria foliicola L. Lombard & Crous 2015

Notes

Pseudonectria foliicola can be distinguished from P. buxi by the formation of simple conidiophores in the asexual state, something not reported for P. buxi (Bezerra 1963, Rossman et al. 1993). Also, no setae were observed surrounding the sporodochia of P. foliicola, while setae formation is characteristic of P. buxi (Bezerra 1963, Rossman et al. 1993). The conidia of P. foliicola are also smaller than those of P. buxi, which are 8–12 × 2.5–3 μm(Bezerra 1963).
