A new species of
,
(Togniniaceae), was isolated during a diversity study of freshwater fungi from Yunnan Province in China. Morphological and cultural studies of the fungus were carried out and its ...sexual and asexual morphs (holomorph) are introduced herein. This species is characterised by peculiar long-necked, semi-immersed ascomata with oval to ellipsoid ascospores and ellipsoid to ovoid conidia. Phylogenetic analyses of a combined TUB and ACT gene dataset revealed that strains of
constitute a strongly supported independent lineage and are related to
and
. The number of nucleotide differences, across the genes analysed, also supports establishment of
as a new species.
Broomella and Hyalotiella are poorly known genera in Amphisphaeriaceae . Both genera are known from morphological descriptions, but lack molecular data, thus their generic placement and relationships ...with other genera are unclear. Three collections of Amphisphaeriaceae were made from dead twigs of Clematis in Italy, and two from Spartium species and were identified as Broomella and Hyalotiella species. In order to obtain a phylogenetic understanding of Broomella and Hyalotiella within the family Amphisphaeriaceae , we carried out a phylogenetic analysis based on LSU gene data. Results show that these five isolates represent two distinct genera. Based on both morphological and phylogenetic data, the three isolates form Clematis are shown to be conspecific with Broomella vitalbae . In this paper we designated an epitype with a sexual and asexual morph for B. vitalbae to stabilize the understanding of the genus. The two strains from Spartium fit within the generic concepts of Hyalotiella , but sequence data for Hyalotiella species are presently lacking. Hyalotiella spartii sp. nov. is introduced based on its host association and morphological characters.
The authors established the taxonomic status of endophytic fungi associated with leaves of Pandanaceae collected from southern Thailand. Morphotypes were initially identified based on their ...characteristics in culture and species level identification was done based on both morphological characteristics and phylogenetic analyses of DNA sequence data. Twenty-two isolates from healthy leaves were categorised into eight morphotypes. Appropriate universal primers were used to amplify specific gene regions and phylogenetic analyses were performed to identify these endophytes and established relationships with extant fungi. The authors identified both ascomycete and basidiomycete species, including one new genus, seven new species and nine known species. Morphological descriptions, colour plates and phylogenies are given for each taxon.
Species of Dothiorella are common plant pathogens or saprobes found mainly on a variety of woody hosts, with a cosmopolitan distribution. Strains of Dothiorella were isolated from the stems of ...Symphoricarpos sp. and Cornus sanguinea in Italy. Morphological characters, as well as phylogenetic analyses of the internal transcribed spacer region (ITS4, ITS5) and partial sequences of the translation elongation factor 1-α genes were used to characterize and distinguish the two isolates. One is conspecific to D. sarmentorum previously from Menispermum canadense collected in Sweden, and a description for this species is provided. The second species could not be assigned to any known species of Dothiorella. Dothiorella symphoricarposicola sp. nov. from Symphoricarpos is described and illustrated herein, and compared with similar Dothiorella taxa.
