The ascomycete family Nectriaceae (Hypocreales) includes numerous important plant and human pathogens, as well as several species used extensively in industrial and commercial applications as biodegraders and biocontrol agents. Members of the family are unified by phenotypic characters such as uniloculate ascomata that are yellow, orange-red to purple, and with phialidic asexual morphs. The generic concepts in Nectriaceae are poorly defined, since DNA sequence data have not been available for many of these genera. To address this issue we performed a multi-gene phylogenetic analysis using partial sequences for the 28S large subunit (LSU) nrDNA, the internal transcribed spacer region and intervening 5.8S nrRNA gene (ITS), the large subunit of the ATP citrate lyase (acl1), the RNA polymerase II largest subunit (rpb1), RNA polymerase II second largest subunit (rpb2), α-actin (act), β-tubulin (tub2), calmodulin (cmdA), histone H3 (his3), and translation elongation factor 1-alpha (tef1) gene regions for available type and authentic strains representing known genera in Nectriaceae, including several genera for which no sequence data were previously available. Supported by morphological observations, the data resolved 47 genera in the Nectriaceae. We re-evaluated the status of several genera, which resulted in the introduction of six new genera to accommodate species that were initially classified based solely on morphological characters. Several generic names are proposed for synonymy based on the abolishment of dual nomenclature. Additionally, a new family is introduced for two genera that were previously accommodated in the Nectriaceae.

“…In the last five years, our research group has actively contributed to the increase in the number of coprophilous fungi by describing new genera and species. One example includes Rodentomyces reticulatus , a new species included in the recently described genus Rodentomyces , a fungus collected from rodent dung and described using a morphological, cultural and molecular approach. In 2012, Doveri et al .…”

Coprophilous fungi are a large group of saprotrophic fungi mostly found in herbivore dung. The number of these fungi undergoing investigation is continually increasing, and new species and genera continue to be described. Dung-inhabiting fungi play an important ecological role in decomposing and recycling nutrients from animal dung. They produce a large array of bioactive secondary metabolites and have a potent enzymatic arsenal able to utilise even complex molecules. Bioactive secondary metabolites are actively involved in interaction with and defence against other organisms whose growth can be inhibited, resulting in an enhanced ecological fitness of producer strains. Currently, these antibiotics and bioactive secondary metabolites are of interest in medicine in particular, while very little information is available concerning their potential use in agriculture. This review introduces the ecology of dung-inhabiting fungi, with particular emphasis on the production of antibiotic compounds as a means to compete with other microorganisms. Owing to the fast pace of technological progress, new approaches to predicting the biosynthesis of bioactive metabolites are proposed. Coprophilous fungi should be considered as elite candidate organisms for the discovery of novel antifungal compounds, above all in view of their exploitation for crop protection.

“…In continuous survey to search natural bioactive compounds, and with the aim to put light on the complex ecology of this group of fungi, also by an eco‐chemical approach, metabolites produced by new or rare fimicolous fungi have been recently studied . The organic extract of solid cultures of the recently described fimicolous Cleistothelebolus nipigonensis and Neogymnomyces virgineus showed strong antifungal activity against different filamentous fungi and fungal‐like organisms .…”

Herbivorous mammal dung supports a large variety of fimicolous fungi able to produce different bioactive secondary metabolites to compete with other organisms. Recently, the organic extracts of the Solid State Fermentation (SSF) cultures of Cleistothelebolus nipigonensis and Neogymnomyces virgineus, showing strong antifungal activity, were preliminarily investigated. This manuscript reports the isolation of the main metabolites identified, using spectroscopic and optical methods, as fusaproliferin (1) and terpestacin (2). Furthermore, some key hemisynthetic derivatives were prepared and their antifungal activity was tested against the same fungi previously reported to be affected by the organic extracts obtained from SSF. These metabolites and their derivatives resulted able to reduce the growth of Alternaria brassicicola, Botrytis cinerea and Fusarium graminearum in a variable extent strongly dependent from chemical modifications and test fungi. The hydroxy enolic group at C(17) appeared to be a structural feature important to impart activity. This study represents the first report of these secondary metabolites produced by C. nipigonensis and N. virgineus.
