Summary: Panochthus Burmeister is a diversified and widely distributed glyptodont in the Pleistocene of South America, with a dorsal carapace from the surroundings of Potosi, Bolivia showing morphological peculiarities compared to other species within the genus. The combination of characters suggests that it may belong to a new species or an unknown species with regards to the dorsal carapace.

Summary: In this study, four new species of Russula subg. Brevipedum collected from China were described based on morphological characteristics and molecular evidence. These species include Russula brevispora, Russula flavescens, Russula longicollis, and Russula pseudojaponica. Detailed descriptions of their external features and spore morphology were provided, and phylogenetic analyses were conducted.

Summary: A hyperproducer isolate of Paraboeremia sp. was obtained from the Las Yungas rainforest in Argentina, representing the first native reported species of this genus in South America. Through genetic and morphological analyses, a new South-American species, Paraboeremia yungensis, was described and proposed based on distinctive features from previously described species within the genus.

Summary: Grasses are a diverse family of plants, but their classification and evolutionary history are obscured by the similarity in their pollen morphology. Using high-resolution imaging and computational analysis, this study establishes a reference framework for the surface ornamentation of grass pollen and confirms its diversity across the phylogeny. The findings support the use of descriptive terminology and quantitative features in classifying grass taxonomic boundaries.

Summary: This study evaluated the possibility of using DNA barcoding regions to distinguish Vicia taxa in South Korea. The results showed well-resolved phylogeny and effective discrimination of several Vicia species using combined barcoding regions. Further investigation of morphological characteristics was conducted to differentiate unclassified species, with 16 selected traits efficiently distinguishing all Vicia species.

Summary: Morphological diversity is an important component of biodiversity and understanding the evolutionary history and morphological evolution of plants. The morphospace of Asterales pollen is phylogenetically structured, but there is no significant difference in disparity among different taxonomic groups. Additionally, there is mixed evidence for whole-genome duplication driving the morphological evolution of Asterales pollen.

Summary: Panochthus is one of the most abundant and diverse glyptodont genera in South America during the Pleistocene, with eight species and large size. The relationship between the shape of the caudal tube and its usage as weapons in Panochthus species is explored, with different forms appearing in different time periods.

Summary: Differences in tree species richness between South America and Africa are primarily due to certain key families in South American moist forests and dry vegetation types. The tree floras of South America and Africa are organized similarly, and further research on these key families could provide insights into the processes leading to South America's exceptional plant species diversity.

Summary: This study presents the formal description of a new species of lichen photobiont (Trebouxia lynnae) and provides a comprehensive characterization of its cellular ultrastructure, physiological traits, and genetic and genomic diversity. The findings contribute to our understanding of the diversity and distribution of symbiotic green microalgae in lichen formation.
