Summary: In this study, phylogenetic analyses were conducted on Perenniporia species and related genera using DNA sequences of multiple loci. It was found that the genus Perenniporia is polyphyletic. Based on morphology and phylogeny, 15 new genera were proposed, 2 new species were described, and 37 new combinations were proposed. Illustrated descriptions of the new species were provided, along with identification keys to Perenniporia and its related genera.

Summary: During a study on wood-inhabiting fungi in the USA, four unknown specimens were identified as two new species of Fuscoporia - F. hawaiiana and F. minutissima, based on morphological and molecular genetic analyses. F. hawaiiana is characterized by pileate basidiocarps, absence of cystidioles, hooked hymenial setae, and ellipsoid to subglobose basidiospores. F. minutissima is distinguished by small pores and basidiospores. The taxonomic status of these two species is briefly discussed and a key to North American Fuscoporia species is provided.

Summary: Two new species, Fulvifomes acaciae and Pyrrhoderma nigra, have been described and illustrated based on morphological and phylogenetic analyses. F. acaciae is characterized by ash gray to dark gray, encrusted and cracked pileal surface, circular pores with entire dissepiments, and ellipsoid basidiospores. P. nigra is characterized by dark gray to black pore surface, small circular pores, and ellipsoid basidiospores. The differences between these new species and closely related species are discussed, and identification keys for Fulvifomes and Pyrrhoderma are provided.

Summary: Seven undescribed 22-hydroxylanostane triterpenoids were isolated from the fruiting bodies of Phellinus igniarius, with their structures determined by extensive spectroscopic and HRESIMS data analyses. Stereoselective synthesis of 22S/22R25,26,27-Trinorlanosta-8-en-3 beta,22,24-triols was achieved for the first time, with cardioprotective activity demonstrated by Phellinols A, B, and F.

Summary: A new species, Fuscoporia kenyana sp. nov. from Kenya, Eastern Africa, is described and illustrated in this study. The phylogenetic analyses based on nLSU and ITS+nLSU datasets confirm that Fuscoporia kenyana is a new taxon in the genus Fuscoporia. In addition, annotated identification keys are provided for African species and different types of Fuscoporia.

Summary: A new species, Fuscoporia hainanensis sp. nov., is described based on specimens from China. Phylogenetic analyses showed that this new species belongs to the F. contigua group and is distinct from other species. It has specific characteristics such as annual basidiocarps with medium sized pores, aseptate skeletal hyphae, presence of mycelial setae, hymenial setae and cystidioles, and cylindric basidiospores.

Summary: In the field of plant disease control, the identification of bacterial strains as Pseudomonas marginalis was based on characteristics such as fluorescence, oxidase negativity, potato soft rot, and positive arginine dihydrolase. However, with the introduction of phylogenetic and genomic analyses, it was discovered that Pseudomonas marginalis is heterogeneous and may contain many cryptic species. A survey was conducted to sort the strains preserved in the NARO Genebank into Pseudomonas marginalis sensu stricto and other strains. Some of these strains were found to be novel species, including Pseudomonas kitaguniensis, Pseudomonas allii, Pseudomonas cyclaminis, Pseudomonas petroselini, Pseudomonas brassicae, Pseudomonas lactucae, Pseudomonas aegrilactucae, and Pseudomonas morbosilactucae. This article briefly introduces the profiles of these novel species and discusses the challenges in reorganizing Pseudomonas marginalis sensu lato.

Summary: The study on genome size variation in Dianthus sylvestris populations from the Balkan Peninsula and the European Alps revealed significant differences between diploid and tetraploid populations, with tetraploids showing genome downsizing and distinct morphological and environmental characteristics compared to diploids. There is geographical and partial taxonomical correlation in relative genome size within diploid populations, with higher RGS in the southern Balkan Peninsula and the Alps. Greater RGS variation was observed among Balkan populations compared to the Alps, indicating more pronounced evolutionary differentiation in the Balkan Peninsula, while deep RGS divergence in the Alps suggests persistence of alpine populations in different Pleistocene refugia.

Summary: In this study, we conducted a taxonomic and phylogenetic study on Peniophora. Through analysis of ITS and 28S sequence data of all available species, we found that Peniophora should be considered a large genus instead of three small genera. We also discovered four new species. This study reveals the rich species diversity of corticioid fungi in Asia and calls for further research.

Summary: This study investigated the chromosome evolution of Crepis plants by analyzing the chromosome base number and organization of rDNA loci in 39 species. The results showed that despite variations in rDNA loci organization, most species had rDNA loci on the same chromosome arm. Comparative analysis revealed multiple independent gains of rDNA loci and repositioning during diversification and speciation. These findings provide important insights into the evolutionary mechanisms and speciation of Crepis plants.

Summary: Bacillus cereus sensu lato (s.l.) is a bacterium that includes foodborne pathogens and beneficial microorganisms. Some of the beneficial and commercially used strains have been found to carry enterotoxin gene, which can cause toxicoinfection in humans. Better surveillance and characterization of virulence capacity are needed for B. cereus s.l. strains.
