Verrucostoma freycinetiae gen. et sp. nov. is described and illustrated from specimens on dead leaves of Freycinetia boninensis (Pandanaceae) collected in Hahajima, Bonin (Ogasawara) Islands, Japan. The genus is characterized by pale orange perithecia with protuberances around the perithecial apex, no color change in 3% potassium hydroxide and lactic acid, unitunicate asci, spinulose ascospores and an Acremonium-like anamorph. Morphological characters were compared with other genera in the Bionectriaceae and Nectriaceae (Hypocreales). Verrucostoma is morphologically similar to Bionectria (Bionectriaceae) from which it differs in the formation of conspicuous protuberances around the perithecial apex and the Acremonium-like anamorph. Moreover molecular analyses of Verrucostoma and other members of the Bionectriaceae and Nectriaceae based on alpha-actin, large subunit nuclear ribosomal DNA and RNA polymerase II subunit 1 sequences support the conclusions based on morphological data. Our results confirm that V. freycinetiae is distinct from other genera among the Nectria-like fungi and represents a new genus belonging to the Bionectriaceae.

“…Additional gene regions also were sequenced depending on the species complex. Threelocus haplotypes were obtained for 23 isolates within the FSSC by sequencing portions of EF-1a, RPB2 and the nuclear rDNA region comprising the internal transcribed spacer (ITS) region and the 59 end of the large ribosomal RNA subunit gene (LSU) as described by O'Donnell (2000, O'Donnell et al 2008. Similarly two-locus haplotypes were obtained for 202 members of the FOSC by sequencing a portion of EF-1a and a ,2000 bp portion of the intergeneric spacer (IGS) region of the nuclear ribosomal RNA gene repeat as described by O'Donnell et al (2009a).…”

Multilocus phylogenetics show high levels of endemic fusaria inhabiting Sardinian soils (Tyrrhenian Islands)

et al. 2010

The Mediterranean island of Sardinia is well known for high levels of vascular plant diversity and endemism, but little is known about its microbial diversity. Under the hypothesis that Fusarium species would show similarly high diversity, we estimated variability in Fusarium species composition among 10 sites around the island. Markers previously adopted for multilocus sequence typing (MLST) were used to determine multilocus DNA sequence haplotypes for 263 Fusarium isolates. In addition portions of the translation elongation factor 1-alpha and second largest RNA polymerase subunit genes were sequenced for all isolates. The intergenic spacer (IGS) region of the nuclear ribosomal RNA gene repeat was sequenced for members of the F. oxysporum species complex (FOSC), and a portion of the nuclear ribosomal RNA gene repeat comprising the internal transcribed spacer (ITS) and part of the large nuclear ribosomal RNA subunit was sequenced for members of the F. solani species complex (FSSC). Seventy-three multilocus haplotypes were identified among the 263 isolates typed, of which 48 represented FOSC and FSSC. Thirty-seven of 48 FOSC two-locus and FSSC three-locus haplotypes had not been observed previously. The 38 non-FOSC/FSSC fusaria comprised 25 haplotypes distributed among 10 species, five of which appear to represent novel, phylogenetically distinct species. In general newly discovered haplotypes were restricted to one or a few sites. All FSSC isolates represented new haplotypes in phylogenetic species FSSC 5 and 9, which differ from the phylogenetic species dominant in soils worldwide. No obvious correlations were found between haplotype diversity and geospatial or habitat distribution. Overall these results indicate a high degree of Fusarium genetic diversity on multiple geographic scales within Sardinia. These results contrast with recent work showing that common, cosmopolitan species dominate Sardinia's Trichoderma biodiversity. All data are available for access and viewing from the FUSARIUM-ID database.

“…Each of these mating groups represented one of the formae speciales that corresponded to pathogenicity on specific plant host species and cultivars. Phylogenetic analyses have consistently demonstrated that F. solani represents a complex of mostly morphologically cryptic species, now known as the F. solani species complex (FSSC;O'Donnell 2000, O'Donnell et al 2008, Zhang et al 2006, Nalim et al 2011, Short et al 2013. These analyses suggest that the FSSC consists of three major clades encompassing over 60 phylogenetic species.…”

Epitypification of Fusisporium (Fusarium) solani and its assignment to a common phylogenetic species in the Fusarium solani species complex

et al. 2016

Fusisporium solani was described as the causal agent of a dry rot of potato in Germany in the mid 19th century. As Fusarium solani, the species became known as a plurivorous plant pathogen, endophyte, decomposer, and opportunistic pathogen of humans and nutritional symbiont of insects. In parallel, it became evident that the morphologically defined species F. solani represents a phylogenetically and biologically complex group of often morphologically cryptic species that has come to be known in part as the F. solani species complex (FSSC), accommodating several formae speciales and mating populations/biological species. The FSSC currently includes more than 60 phylogenetic species. Several of these have been named, but the majority remains unnamed and the identity of F. solani sensu stricto is unclear. To promote further taxonomic developments in the FSSC, lectoand epitypification is proposed for Fusisporium solani Although no type material for F. solani is known to exist, the species was abundantly illustrated in the protologue. Thus, a relevant illustration provided by von Martius is selected as the lectotype. The epitype selected here originates from a rotting potato collected in a field in Slovenia. This strain causes a dry rot of artificially inoculated potatoes. It groups in the heretofore unnamed phylogenetic species 5, which is nested within clade 3 of the FSSC (FSSC 5). Members of this phylogenetic species have a wide geographic distribution and include soil saprotrophs and plant and opportunistic human pathogens. This typification is consistent with the original description of Fusisporium solani and the concept of F. solani as a widely distributed soil inhabitant and pathogen.
