Summary: Entomosporium leaf spot (ELS) is a serious disease that affects hawthorn plants worldwide. Diplocarpon mespili is the most commonly reported pathogen causing this disease. In this study, the pathogen causing ELS on hawthorn in China was identified as a distinct species, D. mespilicola sp. nov, which is similar to D. mespili. The study also determined the optimal temperature and minimum germination time for the pathogen's conidia. This information may be useful in developing disease management strategies for hawthorn production in the future.

Summary: In this study, two fungi were isolated from the infected skin of a diabetic male. A novel species, Simplicillium sinense, was identified based on its morphological characteristics and phylogenetic analysis. The fungus showed slow growth and resistance to most antifungal drugs. Treatment with oral terbinafine and topical terbinafine cream resulted in the resolution of the rash without recurrence after 6 months of follow-up. Simplicillium sinense is a new fungal taxon and terbinafine is recommended as the first-line treatment for Simplicillium infection.

Summary: Calycina-like specimens were collected in Doi Inthanon National Park, Thailand. The new discomycete specimen was identified as Calycina montana, characterized by its amber color, stipitate apothecia, gelatinized ectal excipulum, cylindrical asci, and ellipsoidal ascospores. Additionally, the new combination of Bisporella shangrilana as Calycina shangrilana was confirmed, resolving the confusion of Bisporella placement in Pezizellaceae.

Summary: In this study, a putative NmrA-like protein, Lws1, was identified in Lasiodiplodia theobromae and its pathogenic role and interaction with nutrition metabolism were investigated. Lws1 was found to function as a negative regulator in disease development and its transcription was affected by external carbon and nitrogen sources. It was also shown to interact with a putative GATA family transcription factor, LtAreA.

Summary: This study re-evaluated the character evolution and taxonomic placements of Botryosphaeriales species. It found that the order originated around 109 million years ago in the early Cretaceous period. The study also assessed two hypotheses and found a relationship between conidial color and nutritional mode in botryosphaerialean taxa.

Summary: The Greater Mekong Subregion (GMS) is a diverse geographic landscape and one of the richest biodiversity hotspots in the world with high fungal diversity. This study collected samples from terrestrial habitats in the GMS, focusing on woody litter fungi diversity in northern Thailand and the Yunnan Province of China. Morphological characteristics and phylogenetic analyses supported the identification of new species in the family Didymosphaeriaceae. The study identified seven species of woody litter fungi, including a new monotypic genus, five novel species, and new host records for two species. Additionally, the study provides a summary of a species in the Montagnula genus based on morphological characteristics.

Summary: Bats are the second largest group of mammals, with over 1400 species found across six continents. They have unique characteristics such as long lifespan and ability to tolerate viruses without symptoms, making them important in terms of disease risk. The warm, humid habitats where bats live also provide favorable conditions for fungi growth.
