Shiraiaceae is an important family in Pleosporales (Dothideomycetes), which includes medical fungi and plant pathogens. Two hypocrellin-producing taxa,
Shiraia bambusicola
and a novel genus
...Rubroshiraia
gen. nov.
, typified by
Rubroshiraia bambusae
are treated in this article. Maximum likelihood analysis, generated via RAxML (GTR+G model), using a combined SSU, LSU, TEF1 and RPB2 sequence dataset, shows that
Rubroshiraia
is close to
Shiraia
and belongs to the family Shiraiaceae. Descriptions, illustrations and a taxonomic key are provided for the genera in Shiraiaceae.
Rubroshiraia
morphologically differs from
Shiraia
in having small and dark ascostromata and filiform ascospores. Production of the ascostromatal metabolites, hypocrellin A and B, were examined by HPLC and spectrophotometer. The content of hypocrellin A and B of specimen HKAS 102255 (
R. bambusae
) is twice that produced by HKAS 102253 (
S. bambusicola
). To clarify the relationship between
R. bambusae
and
Hypocrella bambusae
, type material of the latter was examined and provided the illustration.
During a survey of microfungi associated with grasslands and related vegetation types from Yunnan Province in China, various ascomycetous and coelomycetous fungi were isolated. This study reports the ...discovery of four strains of ascomycetous and coelomycetous fungi from dead stalks of
Hypericum monogynum
L. (Hypericaceae) and
Rubus parvifolius
L. (Rosaceae) in the Zhaotong region of Yunnan Province, China. The isolates were characterized using multi-locus phylogenetic analyses and were found to represent a new monophyletic lineage in Melanommataceae (Pleosporales, Dothideomycetes). This new clade was named as
Dematiomelanomma yunnanense
gen. et sp. nov. which consists of both sexual and asexual morphs. The sexual morph is characterized by globose to subglobose ascomata with a central ostiole, cylindrical asci with a pedicel and ocular chamber, and muriform, ellipsoidal to fusiform ascospores. The asexual morph has synanamorphs including both brown, muriform macroconidia and hyaline, round to oblong or ellipsoidal microconidia. These findings contribute to the understanding of fungal diversity in grasslands and related vegetation types in Yunnan Province, China.
Fungi are a large and diverse group of microorganisms, and although the estimated number of species ranges between 2 and 11 million, only around 150,000 species have been described thus far. The ...investigation of plant-associated fungi is beneficial for estimating global fungal diversity, for ecosystem conservation, and for the continued development of industry and agriculture. Mango, one of the world's five most economically important fruit crops, is grown in over 100 countries and has been demonstrated to have a great economical value. During surveys of mango-associated saprobic fungi in Yunnan (China), we discovered three new species (
,
and
) and five new records. The phylogenetic analyses of multi-gene sequences (LSU, SSU, ITS,
,
-
and
) coupled with morphological examinations were used to identify all the taxa.
In this study, we report the discovery of
Jahnula dianchia
sp. nov., a freshwater lignicolous fungus belonging to the order Jahnulales (Dothideomycetes, Ascomycota), from a submerged woody substrate ...from Dianchi Lake, Yunnan, China. Morphologically, this new taxon differs from other species of the genus in ascospore morphology; the ascospores of the new species are dark brown with mammiform apices. We also provide a phylogenetic tree showing the molecular relationships between the new taxon with the previously accepted
Jahnula
species. The analysis of combined ITS, LSU, and SSU sequence dataset places
J
.
dianchia
within the Jahnulales sister to
J
.
sangamonensis
. The phylogeny also shows the placement of both strains of
J
.
dianchia
in a well-supported independent sub-clade.
belongs to the family Acanthaceae and is a widely distributed dicotyledonous plant in tropical and subtropical regions. Three isolates of
(Dothideomycetes, Pleosporales, Didymellaceae) were collected ...from leaves of
in Guangxi Province, China.
Phylogenetic analyses of a combined ITS-LSU-

dataset indicate that one of our three strains represents an undescribed species with close affinity to

. This is the first report about taxa of
from this host plant.
The cosmopolitan plant genus
Clematis
contains many climbing species that can be found worldwide. The genus occurs in the wild and is grown commercially for horticulture. Microfungi on
Clematis
were ...collected from Belgium, China, Italy, Thailand and the UK. They are characterized by morphology and analyses of gene sequence data using an integrated species concept to validate identifications. The study revealed two new families, 12 new genera, 50 new species, 26 new host records with one dimorphic character report, and ten species are transferred to other genera.
