A coelomycete with characters resembling the asexual morphs in the family Botryosphaeriaceae was isolated from a fallen leaf of an orchid collected in Thailand. Morphological and phylogenetic ...analyses placed the strain in Neoscytalidium. Phylogenetic relationships among Neoscytalidium species were inferred by analyzing internal transcribed spacers and large subunit of rRNA sequence data and indicate that our strain is a new species, which is introduced and illustrated herein as Neoscytalidium orchidacearum sp. nov.
Three arecophila-like fungal samples were collected on dead culms of gramineous plants in China. Morphological studies of our new collections and the herbarium specimen of
Arecophila gulubiicola
...(generic type) were conducted and the morphological affinity of our new collections with
Arecophila
was confirmed. Maximum likelihood and Bayesian analyses using combined ITS, LSU,
rpb
2 and β-tubulin data from our collections revealed the phylogeny of
Cainiaceae
. The monospecific genus
Alishanica
(type species
Al. miscanthi
), which had been accepted in
Cainiaceae
, is revisited and synonymised under
Arecophila
. Based on morphology and phylogeny,
Arecophila australis
sp. nov. and
A. clypeata
sp. nov. are introduced as new species, while
A. miscanthi
is a new record for China. All the new collections are illustrated and described.
During an investigation of Xylariaceae from 2019 to 2020, isolates representing eight
Nemania
(Xylariacese) species were collected from Yunnan, Guizhou and Hainan Provinces in China. Morphological ...and multi-gene phylogenetic analyses, based on combined ITS, α-actin,
rpb2
and β-tubulin sequences, confirmed that six of them are new to science, viz.
Nemania camelliae
,
N. changningensis
,
N. cyclobalanopsina
,
N. feicuiensis
,
N. lishuicola
and
N. rubi
; one is a new record (
N. caries
) for China and one is a known species (
N. diffusa
). Morphological descriptions and illustrations of all species are detailed. In addition, the characteristics of
Nemania
are summarised and prevailing contradictions in generic concepts are discussed.
Several micro fungi were gathered from bamboo and palm in Guizhou Province, China. In morphology, these taxa resemble
,
and
. Multi-gene phylogenetic analyses based on combined ITS, LSU, SSU,
2 and
1 ...loci confirmed that two are new geographical records for China, (
,
), while two of them are new to science (
sp. nov. and
sp. nov.). The stromata of
are similar to those of
, but its ascospores are larger. In addition, multi-gene phylogenetic analyses show that
is closely related to
, but the J- ascus subapical ring as well as the ascospores of
are smaller. Morphological descriptions and illustrations of all species are provided.
A new species Rosellinia convexa from China is illustrated and described. Phylogenetic analysis based on internal transcribed spacer (ITS) region of nuclear ribosomal DNA (including ITS1, 5.8S rRNA ...gene and ITS2), β-tubulin gene, α-actin gene and Polymerase II second largest subunit (RPB2) gene sequence data confirmed that it differed from other species in this genus. On the basis of evidence from morphology, it differs from other Rosellinia species in having brown ascospores with convex umbilical ends and a larger ascal apical apparatus.
•In this paper, one new species from China is illustrated.•The species is described based on morphological characters and phylogenetic analyse.•Phylogeny based on the ITS dataset showed Rosellinia were divided with the sizes of ascospores clearly.
Ganoderma sichuanense ( Ganodermataceae ) is a medicinal mushroom originally described from China and previously confused with G. lucidum . It has been widely used as traditional medicine in Asia ...since it has potential nutritional and therapeutic values. We collected 8 specimens of Ganoderma species from Thailand and show that they represent the first record of G. sichuanenese for Thailand. In this paper, we describe our specimens of Ganoderma sichuanense based on fresh basidiomes, and provide line drawings and photographs. The data from macro- and microscopic features are consistent with the characteristics of the species. Analysis of ITS sequence data indicates that the Thai collections cluster in same species clade as the epitype of G. sichuanense .
