Summary: By analyzing four DNA regions and increasing the sample size, this study found that Caespitosa species are distributed in seven morphologically distinct clades, which are correlated with other informal groups. It also discovered that one clade is associated with geographic isolation. The study also discusses the comparison with other studies, the polyphyly of the Macrophylla group, and the need for future molecular studies in Paspalum.

Summary: Poaceae (the grasses) is a economically important angiosperm family, with a wide global distribution and diverse ecosystems. A comprehensive analysis of genomic and transcriptomic data was conducted to reconstruct the phylogeny of Poaceae, providing strong support for the monophyly of 11 subfamilies and suggesting multiple independent origins of C4 photosynthesis. This study offers valuable resources and insights for evolutionary analyses of the grass family.

Summary: The classification and diversity of ligules in Poaceae plants are still a subject of debate, with different hypotheses proposed. This study found that the majority of Poaceae representatives have homoligulate ventral ligules, with Panicoideae subfamily displaying the greatest morphological diversity. Dorsal and culm leaf ligules mainly occur in Puelioideae and Bambusoideae, and reversals in ligule types have occurred within subfamilies.

Summary: This study presents a revision of Agrostis based on morphoanatomical evidence, focusing on the Megamexico 3 biogeographic region (Mexico, desert areas of southern USA, and Central America to northern Nicaragua). It provides taxonomic descriptions, an identification key, distribution maps, and figures of morphoanatomical characteristics, elevation, and phenology. Among the 20 Agrostis species in the study zone, four are endemic and three are introduced. Most records are found in the mountains above 1500 m a.s.l., in open areas of temperate forests with conifers and Quercus. Spikelets occur year round, but the majority of records are during the wet season from July to October.

Summary: This study analyzed the morphological variation of the Saccharum complex and identified three main groups within the complex. It supported the idea that Erianthus should be accepted as a distinct genus from Saccharum based on morphological differences. The research also provided morphological traits to distinguish Tripidium from Saccharum and Erianthus.

Summary: Brown blight, a devastating disease for tea cultivation in Taiwan, was surveyed from 2017 to 2019 to understand the fungal diversity and population composition. The study identified three species associated with brown blight of tea: Colletotrichum camelliae (95.6%), C. fructicola (3.7%), and C. aenigma (0.7%). This is the first report of C. aenigma in Taiwan. The pathogenicity of Colletotrichum spp. was most prominent in wounded leaves, and preventive application of fungicides or biocontrol agents at an early leaf stage is recommended.

Summary: The South China Botanical Garden (SCBG) conserves important plant germplasms of endangered species and studying the associated mycobiome is essential to maintaining its visual aesthetics. Coelomycetous taxa were collected during a survey of plant-associated microfungal species in SCBG. Phylogenetic relationships were evaluated and three new species, Ectophoma phoenicis, Remotididymella fici-microcarpae, and Stagonosporopsis pedicularis-striatae, were introduced. Additionally, a new host record for Allophoma tropica in the Didymellaceae was described.

Summary: During the investigation, 15 collections of lignicolous freshwater fungi were isolated from submerged decaying wood in the Tibetan Plateau habitat. These fungi display characteristic punctiform or powdery colonies with dark pigmented and muriform conidia. Phylogenetic analysis of their DNA sequences revealed that they belong to three families in Pleosporales. Out of these, four species were identified as new species, while three species were reported as new records in the freshwater habitats of Tibetan Plateau, China. This study provides morphological descriptions and illustrations of the new collections.

Summary: Soil microbial communities and their interactions have a critical role in shaping ecosystem functions at regional and continental scales. Co-occurrence network analyses have been used to study microbial interactions, but understanding how different environmental factors affect these networks at the continental scale is challenging. By analyzing data from Australian study sites, researchers inferred a meta-community level soil microbial cooccurrence network for the continent and found that different vegetation types and environmental factors influenced the topological parameters of these networks.
