Catalogue of fungi in China 4: Didymiaceae and Physaraceae (Myxomycetes)

Mycology&#58 An International Journal on Fungal Biology (2024)

Xue-Fei Li Jiajun Hu Yonglan Tuo You Li Dan Dai

Myxomycetes play crucial ecological roles, yet their species diversity, distribution, and taxonomic relationships remain poorly understood. In this study, we examined 104 specimens from 19 provinces in China. Through morphological analysis, we identified a group of species with reduced lime formation, a feature typically associated with the Physaraceae, but with key morphological similarities to the Diderma. A comprehensive phylogenetic analysis was conducted using three genes (nSSU, EF-1α, and COI), resulting in a dataset of 452 sequences from 116 species. Notably, we identified a distinct clade within Didymiaceae containing species with fewer lime knots, a trait traditionally linked to Physaraceae. This clade, designated as the new genus Neodiderma, was phylogenetically positioned as a sister group to Diderma, potentially representing a transitional group between Didymiaceae and Physaraceae, supported by both morphological and molecular evidence. Eleven new species — N. macrosporum, N. pseudobisporum, N. verrucocapillitium, N. rigidocapillitium, N. rufum, Physarum guangxiense, P. subviride, P. nigritum, P. biyangense, P. neoovoideum, and P. jilinense — were identified from China, and their phylogenetic positions were analysed. Additionally, N. spumarioides (formerly Diderma spumarioides) was recombined. The new and recombined species were formally described and illustrated, and a key to the sections and species of Neodiderma and Physarum was provided.

Multiple evidences reveal new species and a new record of smelly Gymnopus (Agaricales, Omphalotaceae) from China

Frontiers in Microbiology (2022)

Jiajun Hu Li-Ru Song Yonglan Tuo Guiping Zhao Lei Yue

Gymnopus sect. Impudicae is a poorly studied group around the world. However, it is well known for its pungent smell-a total of five species from China belonging to sect. Impudicae were recorded, and included four species new to science-G. epiphyllus, G. cystidiosus, G. subdensilamellatus, and G. subpolyphyllus-which were delimited and proposed based on morphological and molecular evidences, and one new record from Henan, Jiangxi, and Gansu Province, China-G. densilamellatus. Detailed descriptions and illustrations were presented as well as comparisons to similar species. Phylogenetic analysis inferred from the ITS and nLSU dataset supported the Gymnopus as a monophyletic genus which was defined by Oliveira et al., and the novel species grouped as separate lineages within it. A Key to the reported species of Gymnopus sect. Impudicae is also provided.

The Research Hotspots and Development Trends of Network Education in China

Jiajun Hu Haibin Wang Junhua Xu

To explore research hotspots and development trends of network education in China, 499 related articles form the China National Knowledge Infrastructure (CKNI) were analyzed by the CiteSpace. The results show that: (1) the research of network education started as early as 1997 and there were two periods of growth, which were from 2000 to 2005 and from 2017 to present. Deyi Ma, Central China Normal University and Computer Knowledge and Technology topped the lists of contributing authors, organizations and publications respectively. (2) the topics of online education, network teaching, network education, countermeasure, and the comparison between network education and traditional education were the research hotspots in the field. (3) the colleges and universities students' network education were the typical recent research frontiers in the field.

Ecological Factors Influencing the Occurrence of Macrofungi from Eastern Mountainous Areas to the Central Plains of Jilin Province, China

Journal of Fungi (2022)

Jiajun Hu Guiping Zhao Yonglan Tuo Zhengxiang Qi Lei Yue

Macrofungi are essential in forest ecological functioning. Their distribution and diversity are primarily impacted by vegetation, topography, and environmental factors, such as precipitation and temperature. However, the composition and topographical changes of the macrofungi between the eastern mountainous area and central plains of Jilin Province are currently unknown. For this study, we selected six investigational sites representing three different topographical research sites in Jilin Province to assess macrofungal diversity, and applied a quadrat sampling method. Macro- and micro-morphological characteristics combined with the molecular method were used to identify the collected macrofungi. Meanwhile, selected meteorological data were obtained for statistical analysis. As a result, 691 species were identified, of which Agarics were the most common, accounting for 60.23%, while the Cantharelloid fungi were the least common (0.91%). Furthermore, most of the shared genera (species) were saprophytic. The α diversity showed that the species diversity and richness in Longwan National Forest Park (B2) were the highest at the genus level. The mycorrhizal macrofungi proportion revealed that Quanshuidong Forest Farm (A1) was the healthiest. Finally, species composition similarity decreased with the transition from mountainous to hilly plains. We concluded that the occurrence of macrofungi was most influenced by vegetation. The air humidity, precipitation, and wind velocity were also found to significantly impact the occurrence of macrofungi. Finally, the mycorrhizal:saprophytic ratios and species similarity decreased with the transition from the mountainous area to the plains. The results presented here help elucidate the macrofungi composition and their relationship with environmental factors and topography in Jilin Province, which is crucial for sustainable utilization and future conservation.

A new species and new records species of Pluteus from Xinjiang Uygur Autonomous Region, China

PeerJ (2022)

Zhengxiang Qi Keqing Qian Jiajun Hu Yang Wang Dongmei Wu

Xinjiang Uyghur Autonomous Region in China embraces a unique geographical and ecological environment, and the macrofungi represent a rich resource. However, few studies on the genus Pluteus have been reported from Xinjiang. In 2021, the macrofungal resources in Xinjiang were surveyed, and 10 specimens belonging to the genus Pluteus were collected. Based on the morphological study and molecular analysis, three species were recognized, P. aletaiensis , P. brunneidiscus , and P. hongoi . Pluteus aletaiensis is proposed as a new species. It is characterized by its bright yellow lamellae and stipe, brittle texture, subfusiform to vesicular pleurocystidia, with short pedicels to broadly lageniform to obtuse at apices, a hymeniderm pileipellis, containing dark brown intracellular pigment, and it grows on the ground. Pluteus brunneidiscus , a new record to China, is characterized by uneven, smooth, grayish brown to brown pileus, with an entire margin, and pointed or flatter apices intermediate cystidia, without apical hooks. Pluteus hongoi , a new record to Xinjiang Uyghur Autonomous Region, China, is characterized by the apical hook’s structure (commonly bifid) of pleurocystidia. The nuclear internal transcribed spacer (nrITS) and translation elongation factor 1-alpha (TEF1-a) region were used for the molecular analysis. Phylogenetic trees were constructed using both the maximum likelihood analysis (ML) and Bayesian inference (BI). Detailed descriptions of the three species are presented herein. Finally, a key to the list of eight species of the genus Pluteus knew from Xinjiang is provided.

New findings of Neonothopanus (Marasmiaceae, Basidiomycota) from Ghana

Phytotaxa (2021)

Jiajun Hu Yu Li Li Xiao Frederick Leo Sossah Bo Zhang

Specimens of Neonothopanus were collected from Ghana and examined morphologically, and molecularly using the nuclear internal transcribed spacer (nrITS) and nuclear large subunit ribosomal (nrLSU) regions. Three species were recognized viz., Neonothopanus cystidiosus, a new species, Neonothopanus cystidiosus, a new record for Ghana, and Neonothopanus hygrophanus, a species already known from Ghana. Neonothopanus cystidiosus is characterized by brown spots visible on the surface of pileus when mature and the presence of clavate to cylindrical pleurocystidia. Phylogenetic trees constructed using Bayesian Inference and Maximum Likelihood analyses confirmed the results of the morphological study. Descriptions of all three species are presented with molecular work, along with a key to the known species of Neonothopanus. The addition of a new species provides a new perspective on the heterogeneity of Neonothopanus and contributes to increasing knowledge of the fungal diversity of Ghana.
