3 Pezizomycotina: Sordariomycetes and Leotiomycetes

2015
The classes Sordariomycetes and Leotiomycetes comprise a large group of nonlichenized ascomycetous fungi, in which over 15,000 species have been described. The close evolutionary relationship of the two classes was recently defined by molecular phylogenetic analyses and subcellular data.

Placement of Medeolaria farlowii in the Leotiomycetes, and comments on sampling within the class

Mycological Progress, 2009
Medeolaria farlowii, an ascomycetous parasite of Medeola virginiana, has been included as the only member of the family Medeolariaceae and order Medeolariales. Its assignment within the Ascomycota has been problematic due to the lack of distinctive ascomatal form and ascus morphology.

Disentangling the identity of the genus Biatorellina (Leotiomycetes, Ascomycota)

Phytotaxa, 2019
The monotypic genus Biatorellina is currently considered a taxonomic synonym of Tryblidiopsis but has an obscure and complicated history. During the revision of the genus Tympanis a syntype of Biatorellina buchsii was fortuitously found and reviewed. Initially our revision led to the hypothesis that B. buchsii could be conspecific with Tympanis confusa.

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 ...

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.

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.
