During an investigation of helicosporous fungi in China, a total of seven helicosporous hyphomycetes were obtained from decaying wood in the southern region of the country. Based on phylogenetic ...analyses using a combined LSU, ITS,
tef1α
, and
rpb2
sequence matrix, in conjunction with morphological comparisons, these taxa were classified within
Tubeufia
(Tubeufiaceae, Tubeufiales) and were recognized as three new species,
viz. Tubeufia guttulata
,
T. hainanensis
, and
T. muriformis
, as well as one new distribution record,
viz. T. cocois
. Evidence for these new taxa and the new record, descriptions, illustrations, notes, and phylogenetic evidence are provided for the newly collected helicosporous species.

and
. Detailed descriptions and illustrations of the newly discovered taxa and comparisons with similar fungi are provided. In addition, a list and a key to accepted
species are provided.

sp. nov..
Rhexoacrodictys
is accepted in Pleurotheciaceae based on phylogenetic analysis.
Rhexoacrodictys nigrospora
is transferred to
Dematipyriforma
based on phylogenetic analysis and morphological characters.
Pleurothecium aquaticum
and
Rhexoacrodictys fimicola
are reported from Thailand for the first time.
Geastrum
is the largest genus of Geastraceae and is widely distributed all over the world. Four specimens which belong to
Geastrum
were collected during our scientific expedition to Cangshan ...Mountain, Yunnan, China. Based on morphological characteristics and phylogenetic analysis, a new species was introduced.
Geastrum suae
is characterised by its large basidiomata (height 35–70 mm, diameter 18–37 mm) with long stipe (height 10–45 mm), smooth pink exoperidium and sessile globose endoperidial body. Phylogenetic analysis has been carried out, based on the internal transcribed spacer (ITS) and large subunit ribosomal ribonucleic acid (nrLSU) sequence data. The illustration and description for the new taxa are provided.
During the survey of pathogenic fungi on medicinal plant leaves in Yunnan Province, China, two
Cladosporium
-like taxa were isolated from leaf spots of
Paris polyphylla
. Based on morphological ...characteristics and phylogenetic analysis of combined ITS, TEF1-α and ACT genes, two new species were discovered.
Two new species
Cladosporium yunnanensis
and
C. paris
are introduced, the detailed descriptions and illustrations are provided. Morphology of the two new species is compared with other related
Cladosporium
species. This study widens the host diversity of the genus
Cladosporium
.
Pleosporales is the largest order of Dothideomycetes. In recent years, systematics of Pleosporales have undergone considerable revisions. Dictyosporiaceae is one of the newly established families ...within this order proposed to accommodate holomorphic saprobic Dothideomycetes. Currently 18 genera are recognised in Dictyosporiaceae.
The new species,
Jalapriya aquaticum
sp. nov. and
J. apicalivaginatum
sp. nov. were collected from freshwater habitats in Gansu and Yunnan Provinces, China, respectively and are introduced, based on morphology and molecular analysis of combined ITS, LSU, SSU and TEF1-α sequence data. We also recovered one fresh collection of
Dictyocheirospora vinaya
D’souza, Bhat & K.D. Hyde, which is a new record for China.
Jalapriya aquaticum
differs from extant species of
Jalapriya
in rows converging at the apex and apical cells with spherical-like appendages.
Jalapriya apicalivaginatum
differs from extant species of
Jalapriya
in having the rows of conidia mostly arranged in a plane. The phylogenetic analysis place the new collections within Dictyosporiaceae (Pleosporales). Descriptions and illustrations of
Jalapriya aquaticum
,
J. apicalivaginatum
and
Dictyocheirospora vinaya
are provided. A synopsis of characters of species of
Jalapriya
is also provided.
We are studying the freshwater lignicolous fungi along a north-south latitudinal gradient in Asia. In this paper, fresh collections of Minimelanolocus from submerged wood in streams in Yunnan ...Province, China are characterised based on morphology and molecular phylogeny based on three rDNA regions: 18S (SSU), ITS1-5.8S-ITS2 (ITS) and 28S nuclear rDNA (LSU). The phylogenetic analysis of combined LSU and SSU sequence data and a separate analysis of ITS placed the isolates within the family Herpotrichiellaceae, order Chaetothyriales. An updated phylogenetic backbone tree for Chaetothyriales is provided with available ex-type and additional isolates. One of the isolates collected was identified as Minimelanolocus obscurus based on morphology and molecular data. Minimelanolocus aquaticus, M. asiaticus, M. curvatus and M. melanicus are described as new species considering the interspecific ITS variability and morphology. The phylogenetic placement of Minimelanolocus in Chaetothyriales is novel and provides new sequence data for the genus as a distinct lineage in Chaetothyriales. The conidial characters of all the known species in the genus are summarized. Descriptions and illustrations are provided for the five species of Minimelanolocus with notes on their taxonomy and phylogeny.
•Molecular data and morphology are used to characterize fresh collections of Minimelanolocus from aquatic habitats.•The genus Minimelanolocus is placed in Chaetothyriales providing molecular phylogenetic reappraisal.•Four new species of Minimelanolocus are described.
More specimens of
Hydnotrya
have been collected from southwestern China in recent years. Morphological and molecular analyses showed that they belonged to three species of
Hydnotrya
, of which two ...are new to science,
H. oblongispora
and
H. zayuensis
. The third one was
H. laojunshanensis
, previously reported in 2013. The new species are described, and their relationship to other species of
Hydnotrya
is discussed.
H. laojunshanensis
is re-described in more detail. The main morphological characters of 17 species of
Hydnotrya
are compared and a key to them is provided as well.
Ganoderma is a large and diverse genus containing fungi that cause white rot to infect a number of plant families. This study describes G. phyllanthicola and G. suae as new species from Southwest ...China, based on morphological and molecular evidence. Ganoderma phyllanthicola is characterized by dark brown to purplish black pileus surface with dense concentric furrows, pale yellow margin, irregular pileipellis cells, small pores (5–7 per mm) and ellipsoid to sub-globose basidiospores (8.5–10.0 × 6.0–7.5 µm). Ganoderma suae is characterized by reddish brown to oxblood red pileus surface and lead gray to greyish-white pore surface, heterogeneous context, wavy margin and almond-shaped to narrow ellipsoid basidiospores (8.0–10.5 × 5.0–7.0 μm). The phylogeny of Ganoderma is reconstructed with multi-gene sequences: the internal transcribed spacer region (ITS), the large subunit (nrLSU), translation elongation factor 1-α gene (TEF-1α) and the second subunit of RNA polymerase II (RPB2). The results show that G. suae and G. phyllanthicola formed two distinct line-ages within Ganoderma . Descriptions, illustrations and phylogenetic analyses results of the two new species are presented.
