The Family

Lophiostomataceae (Pleosporales, Dothideomycetes) is a ubiquitous family that includes saprobic species associated with a wide variety of substrates in various habitats. DNA based studies have shown numerous genera can be determined within the family Lophiostomataceae that do not always connect to species based on morphological characteristics. An undescribed ascomycete, similar to species of Lophiostomataceae, was collected from dead wood in the South China karst area in Guizhou Province. Phylogenetic analysis of ITS, SSU, LSU and EF1α sequence data revealed that the new taxon nested in the genus Alpestrisphaeria in Lophiostomataceae, thus the novel taxon is introduced as Alpestrisphaeria jonesii. Diagnostic features are erumpent, coriaceous to carbonaceous, subglobose ascomata, a slit-like ostiole with periphyses, filiform pseudoparaphyses, fissitunicate, cylindrical asci and filamentous, 10–15-euseptate, hyaline ascospores. Alpestrisphaeria jonesii can be readily distinguished from the generic type of Alpestrisphaeria, A. terricola by the shape of its asci and ascospores.

Decaying Wood

Conioscypha is an asexual morph genus placed in the family Conioscyphaceae. During our study of brown-spored hyphomycetes, a new taxon C. tenebrosa was found on decaying wood collected in Guizhou Province, China. The new species is characterized by having micronematous, hyaline conidiophores which are often reduced to conidiogenous cells, with a cup-shaped, percurrently developed, multi-collaretted phialide, and globose to subglobose, obovoid conidia with broadly rounded apex and subtruncate base. The phylogenetic analysis of combined LSU, SSU, ITS and RPB2 sequence data showed that isolates of C. tenebrosa are phylogenetically distinct from other species. Conioscypha tenebrosa sp. nov. is therefore introduced here with a description and morphological illustration. Taxonomic notes and a morphological comparison of Conioscypha species are provided.

Size And Morphology

During an assessment of biodiversity of ascomycetous fungi in the South China Karst area in Guizhou Province, China, a novel species of Prosthemium was collected. We isolated the taxon and sequenced the ITS, LSU and TUB gene regions. The novel taxon is characterized by immersed, globose or depressed globose ascomata, flattened, papillate ostioles, cellular pseudoparaphyses, broadly cylindrical to broadly cylindro-clavate asci, narrowly oblong, muriform ascospores and a prosthemium-like asexual morph produced in culture. The result of phylogenetic analysis based on combined ITS, LSU and TUB sequence data indicate that the species belongs to the genus Prosthemium and formed a separate clade within the genus. The new fungus is most similar to Prosthemium betulinum, Pr. intermedium, Pr. neobetulinum and Pr. stellare, from which it differs in the overall smaller size and morphology of sexual morph and asexual morph, as well as phylogeny. Thus new fungus is described and illustrated herein as Prosthemium sinense.

An interesting hyphomycetous taxon was collected on submerged wood in a freshwater stream in Trat Province, Thailand. It is morphologically similar to endophragmiella-like taxa, characterized by macronematous, mononematous conidiophores, monoblastic, enteroblastic conidiogenous cells and clavate to obovoid, septate brown conidia. The unique feature of this taxon is that the mature conidium often bears a young new conidial primordium which develops percurrently from a lower semi-transparent cell and they secede simultaneously. Phylogenetic analyses of a combined LSU, SSU and RPB2 sequence data support the placement of this fungus together with Platytrachelon and close to the family Papulosaceae within Diaporthomycetidae, Sordariomycetes. A new genus is introduced to accommodate the new taxon as Aquimonospora. The novel species Aquimonospora tratensis is described and illustrated and is compared with other morphologically similar taxa.

A New Species

The Epicopeiidae is a small geometroid family distributed in the East Palaearctic and Oriental regions. It exhibits high morphological diversity in body size and wing shape, while their wing patterns involve in various complex mimicry rings. In the present study, we attempted to describe a new genus, and a new species from Vietnam, with comments on two assumed congeneric novel species from China and India. To address its phylogenetic affinity, we reconstructed the phylogeny of the family by using sequence data of COI, EF-1α, and 28S gene regions obtained from seven genera of Epicopeiidae with Pseudobiston pinratanai as the outgroup. We also compared the morphology of the new taxon to other epicopeiid genera to affirm its taxonomic status. The results suggest that the undescribed taxon deserve a new genus, namely Mimaporia gen. n. The species from Vietnam, Mimaporia hmong sp. n., is described as new to science. Under different tree building strategies, the new genus is the sister group of either Chatamla Moore, 1881 or Parabraxas Leech, 1897. The morphological evidence, which was not included in phylogenetic analyses, however, suggests its potential affinity with Burmeia Minet, 2003. This study also provides the first, although preliminary, molecular phylogeny of the family on which the revised systematics and interpretation of character evolution can be based.

Taxonomic System

The fungal genus Conidiobolus sensu lato was delimited into four genera based on morphology and phylogeny. However, the taxonomic placement of C. parvus has not been determined until now. Here, we show that C. parvus belongs to a distinct lineage based on mitochondrial (mtSSU) and nuclear (TEF1 and nrLSU) phylogenetic analyses. Phylogenetic analyses further revealed a new species as sister to C. parvus. We identified a synapomorphy uniting these lineages (azygospore production) that was not observed in other allied genera of the family Ancylistaceae, and erected a new genus Azygosporusgen. nov. for this monophyletic group, with a new combination, A. parvuscomb. nov. as the type species. Within Azygosporus, the novel species A. macropapillatussp. nov. was introduced from China based on morphological characteristics and molecular evidence, which is characterized by its prominent basal papilla, in comparison to other closely related species, measuring 7.5–10.0×5.0–10.0 µm. Our study resolved the phylogenetic placement of C. parvus and improved the taxonomic system of the Ancylistaceae family.

Botryosphaeriales is an important order of diverse fungal pathogens, saprobes, and endophytes distributed worldwide. Recent studies of Botryosphaeriales in China have discovered a broad range of species, some of which have not been formerly described. In this study, 60 saprobic isolates were obtained from decaying woody hosts in southwestern China. The isolates were compared with other species using morphological characteristics, and available DNA sequence data was used to infer phylogenetic analyses based on the internal transcribed spacer (ITS), large subunit rRNA gene (LSU), and translation elongation factor 1-α (tef) loci. Three novel species were illustrated and described as Botryobambusa guizhouensis, Sardiniella elliptica, and Sphaeropsis guizhouensis, which belong to rarely identified genera within Botryosphaeriaceae. Botryobambusa guizhouensis is the second species identified from the respective monotypic genus. The previously known species were identified as Aplosporella hesperidica, Barriopsis tectonae, Botryosphaeria dothidea, Diplodia mutila, Di. neojuniperi, Di. pseudoseriata, Di. sapinea, Di. seriata, Dothiorella sarmentorum, Do. yunnana, Lasiodiplodia pseudotheobromae, Neofusicoccum parvum, Sardiniella celtidis, Sa. guizhouensis, and Sphaeropsis citrigena. The results of this study indicate that numerous species of Botryosphaeriales are yet to be revealed in southwestern China.

The Mongolepidida is an Order of putative early chondrichthyan fish, originally erected to unite taxa from the Lower Silurian of Mongolia. The present study reassesses mongolepid systematics through the examination of the developmental, histological and morphological characteristics of scale-based specimens from the Upper Ordovician Harding Sandstone (Colorado, USA) and the Upper Llandovery–Lower Wenlock Yimugantawu (Tarim Basin, China), Xiushan (Guizhou Province, China) and Chargat (north-western Mongolia) Formations. The inclusion of the Mongolepidida within the Class Chondrichthyes is supported on the basis of a suite of scale attributes (areal odontode deposition, linear odontocomplex structure and lack of enamel, cancellous bone and hard-tissue resorption) shared with traditionally recognized chondrichthyans (euchondrichthyans, e.g., ctenacanthiforms). The mongolepid dermal skeleton exhibits a rare type of atubular dentine (lamellin) that is regarded as one of the diagnostic features of the Order within crown gnathostomes. The previously erected Mongolepididae and Shiqianolepidae families are revised, differentiated by scale-base histology and expanded to include the generaRongolepisandXinjiangichthys, respectively. A newly described mongolepid species (Solinalepis levisgen. et sp. nov.) from the Ordovician of North America is treated as familyincertae sedis, as it possesses a type of basal bone tissue (acellular and vascular) that has yet to be documented in other mongolepids. This study extends the stratigraphic and palaeogeographic range of Mongolepidida and adds further evidence for an early diversification of the Chondrichthyes in the Ordovician Period, 50 million years prior to the first recorded appearance of euchondrichthyan teeth in the Lower Devonian.

Members of Botryosphaeria encompass important plant pathogens, saprobes and endophytes on a wide range of woody hosts worldwide. Botryosphaeria species are difficult to differentiate due to the overlapping morphological characteristics and the molecular data analyses are necessary recently when species identification is carried out. In this study, 28 Botryosphaeria isolates were obtained from decaying woody hosts in six nature reserves in Guizhou province, China. Based on both morphological characteristics and molecular analysis of combined ITS and tef1-α sequence data, four known species (Botryosphaeria dothidea, B. minutispermatia, B. sinensia and B. wangensis) are identified and one new species B. guttulata is introduced. Botryosphaeria sinensia (32% of the isolates obtained from various hosts) is the abundant species, followed by B. dothidea (28.5% of the isolates), B. guttulata (28.5% of the isolates), B. minutispermatia (7% of the isolates) and B. wangensis (4% of the isolates). These results represent the first study of Botryosphaeria species associated with woody hosts from nature reserves in Guizhou province, China. Our findings indicate that there is a potential of Botryosphaeria species remain to be discovered in this unique landform (Karst formations) in Guizhou province, China.

Palms (Arecaceae) are substrates for a highly diverse range of fungi. Many species are known as saprobes and many are important plant pathogens. Over the course of our studies of micro-fungi from palms in Thailand, two new taxa were discovered. Morphological characteristics and phylogenetic analyses of combined ITS, LSU, SSU, and tef1-α sequence data revealed their taxonomic positions within Massarinaceae. There are currently ten genera identified and accepted in Massarinaceae, with the addition of the two new genera of Haplohelminthosporium and Helminthosporiella, that are introduced in this paper. Each new genus is provided with a full description and notes, and each new taxon is provided with an illustration for the holotype. A list of identified and accepted species of Helminthosporium with morphology, host information, locality, sequence data, and related references of Helminthosporium reported worldwide is provided based on records in Species Fungorum 2021. This work provides a micro-fungi database of Haplohelminthosporium, Helminthosporiella, and Helminthosporium which can be modified and validated as new data come to light.
