Biosynthesis of Cytosporones in Leotiomycetous Filamentous Fungi

Journal of the American Chemical Society
Polyketides with the isochroman-3-one pharmacophore are rare among fungal natural products as their biosynthesis requires an unorthodox S-type aromatic ring cyclization. Genome mining uncovered a conserved gene cluster in select leotiomycetous fungi that encodes the biosynthesis of cytosporones, including isochroman-3-one congeners.

Additional α-glucosidase inhibitors from Malbranchea flavorosea (Leotiomycetes, Ascomycota)

The Journal of Antibiotics, 2018
From the rice-based culture of Malbranchea flavorosea, three new compounds namely flavoroseoside B (5-desoxy-5-chloro-flavoroseoside) (2), 4-hydroxy-2-O-α-ribofuranosyl-5-methylacetophenone (3), and (S)-3,4-dihydro-3-(1H-indol-3-ylmethyl)-4-methyl-1H-1,4-benzodiazepine-2,5-dione (4), along with three known compounds, rosigenin (5), massarilactone B (6),

Evidence for the polyphyly of Encoelia and Encoelioideae with reconsideration of respective families in Leotiomycetes

Fungal Diversity, 2016
This study focuses on the genus Encoelia and the subfamily Encoelioideae in the morphologically and ecologically diverse Helotiales. The 28S and 18S rDNA as well as tef1, rpb1 and rpb2 were sequenced for 70 species. Phylogenetic analyses revealed Encoelia and Encoelioideae to be highly polyphyletic, with species distributed among eight major lineages ...

Phylogenetic reassessment of Hyaloscyphaceae sensu lato (Helotiales, Leotiomycetes) based on multigene analyses

Fungal Biology, 2014
Hyaloscyphaceae is the largest family in Helotiales, Leotiomycetes. It is mainly characterized by minute apothecia with well-differentiated hairs, but its taxonomic delimitation and infrafamilial classification remain ambiguous. This study performed molecular phylogenetic analyses using multiple genes including the ITS-5.8S rDNA, the D1-D2 region of ...

Four new species of Crocicreas (Helotiales, Leotiomycetes) from China

2015
Crocicreas species from China are reviewed and nine species are accepted. Four of them with unique set of specific morphological characteristics are described as new: C. boreosinicae, C. korfii, C. minisporum, and C. xinjiangensis. Crocicreas boreosinicae, C. korfii and C. xinjiangensis grow on herbaceous stems, and C.

Bulgariella pulla , a Leotiomycete of uncertain placement, with an uncommon type of ascus opening

Mycologia, 2017
Bulgariella pulla (Leotiomycetes) is redescribed with the addition of characters of the ascus, spores, and habitat that were previously unconsidered. The ascus dehiscence mechanism in Bulgariella is unusual among Leotiomycetes. In this genus, asci lack a pore and open by splitting to form valves.

New species of Microglossum (Leotiales: Leotiomycetes) from Brazil

Phytotaxa
Microglossum is a genus of bright colored earth tongues with hyaline ascospores. Although relatively common in the North Hemisphere, there are very few collections of this genus in South America. In Brazil, one species is recognized: Microglossum rickii, which belongs to the scaly-stipitate group.

Curviclavula, a new genus of anamorphic Helotiales (Leotiomycetes) isolated from air

Mycological Progress, 2015
A new genus Curviclavula, with C. anemophila as the type species, is established to accommodate a hyphomycetous anamorph isolated from a culturable air sample collected outdoors in New Mexico, USA. The fungus is morphologically distinct in having 1–5 times dichotomously branched conidiophores and integrated, terminal or intercalary, indeterminate ...

Lauriomyces, a New Lineage in the Leotiomycetes with Three New Species

Cryptogamie, Mycologie, 2017
Abstract Lauriomyces is an anamorphic genus comprising nine species, found growing on terrestrial leaf litter and wood in tropical habitats. The genus is characterized by solitary or synnematous, pigmented conidiophores bearing acropetal chains of unicellular, hyaline conidia.Amultigene (SSU, LSU & 5.8S) analysis of Lauriomyces strains reveal three ...
