Summary: Disease infections caused by invasive fungi and bacteria are major contributors to agricultural losses and food contamination. In this study, three strains of Trichoderma were screened for their antimicrobial and antibiofilm activities. The tested strains showed inhibitory effects against plant pathogenic fungi and human pathogens, with the Turkish Trichoderma sp.4 strain exhibiting significant inhibitory activity.

Summary: This study investigates the molecular mechanisms of spore germination in Rhizopus delemar, an opportunistic fungal pathogen that causes mucormycosis. The study uses weighted gene co-expression network analysis (WGCNA) to identify a specific module related to resting phase with enrichment in protein phosphorylation, carbohydrate metabolic process, and cellular response to stimulus. The co-expression network analysis also reveals the interaction between cell wall modifying enzymes and novel lncRNAs, some of which are predicted to be endogenous target mimic (eTM) lncRNAs. Overall, this study provides insight into spore germination and identifies potential targets for mucormycosis treatment related to cell wall-related enzymes.

Summary: Wood-inhabiting basidiomycetous fungi in the Dabie Mountains have important economic values and ecological roles. This study identified 175 species, including edible, medicinal, poisonous, and forest pathogenic species. Species diversity was higher in the eastern part of the mountains and was influenced by habitat filtering and competitive exclusion.

Summary: More specimens of Hydnotrya have been collected from southwestern China in recent years. Morphological and molecular analyses showed that they belonged to three species of Hydnotrya, of which two are new to science. The study described the new species and discussed their relationship with other species. It also provided a more detailed description of a previously reported species and a key for distinguishing different species.

Summary: In this study, potential fungal biocontrol agents for Fusarium culmorum were investigated using transcriptional analyses. Trichoderma spp. isolates belonging to four different species were evaluated for their antagonistic effects. The results showed that T. brevicompactum K26 strain had the highest suppressive effect on F. culmorum. The study also identified three genes as reliable markers for evaluating the biocontrol capacities of Trichoderma spp. Overall, this study highlights the importance of finding effective biocontrol agents for combating Fusarium culmorum.

Summary: The genus Ciliochorella is a group of parasitic fungi that are mainly found in subtropical and tropical regions, playing important roles in litter decomposition. This study introduces two new species (Ciliochorella chinensis sp. nov. and C. savannica sp. nov.) discovered in leaf litter collected from savanna-like vegetation in southwestern China. Phylogenetic analysis suggests that these new species form distinct branches within the Ciliochorella genus. Morphological comparisons also highlight the differentiation of these new species within the genus. Furthermore, both new species are capable of cellulose degradation and laccase production.

Summary: Ergot alkaloids, secondary metabolites produced by fungi, contaminate cereal crops and grasses. The C-8-S-isomers, previously considered biologically inactive, have been found to possess bioactivity. Analytical assessments now include the C-8-S-isomers, and high concentrations of specific C-8-S-isomers have been identified. Further research on C-8-S-isomers is warranted, and their inclusion in regulatory recommendations for food and feed is recommended.

Summary: Molecular phylogenetic and chemical analyses, as well as morphological characterization, have led to the discovery of new features in two North American Paraisaria species and new combinations for two known species. The use of chemotaxonomy has proven useful in identifying markers for degraded herbarium specimens where DNA sequencing is not possible.

Summary: The new species Thelocarpon periphysatum is described from marl quarries in the Netherlands. It is characterized by perithecioid ascomata with a green-yellowish ring, abundant periphyses and periphysoids up to 120 μm long, absence of paraphyses, and wide, oblong, and often asymmetrical ascospores. The perithecia are immersed in black cyanobacterial crusts on calcareous rocks. A worldwide key to the 30 currently accepted species of Thelocarpon is provided.

Summary: This study investigates the mutualistic-parasitic continuum dynamics between an orange lichen and a lichenicolous fungus, revealing the impact of the fungus infection on the lichen, including changes in photosynthetic activity, surface roughness, and inhibition of parietin synthesis. This study provides a new level of understanding of interactions within lichens.

Summary: Acrospermales, one of the least studied lineages of Dothideomycetes, exhibit diverse ecological strategies. This study identified a new species, A. bolivianum, which is the first lichenicolous member of Acrospermum and demonstrates a close relationship with bryophilous Acrospermum adeanum. The ancestral lifestyle of Acrospermales is saprotrophic, and the lichenicolous lifestyle has independently evolved at least twice in this group.

Summary: In this study, 25 yeast strains were isolated from soil samples collected in gold mining ore in Gia Lai, Vietnam. Among them, one isolate named GL1(T) exhibited high tolerance to Cu2+ and could grow in a wide range of pH and temperature. The dried biomass of the isolate showed effective removal of Cu2+, and phylogenetic analysis suggested it belonged to a novel Rhodotorula species.

Summary: Amylases are important enzymes for biotechnological and industrial applications. In this study, amylase was successfully produced using peach palm waste as a low-cost substrate under solid state fermentation. The composition of the nitrogen source was optimized to further increase the amylase yield. The physicochemical characterization of the amylase revealed its optimum activity at pH 4.0 and temperature ranging from 50°C to 60°C. The enzyme showed stability in a wide range of pH and temperature conditions. This research demonstrates the potential of cost-effective amylase extraction for industrial applications, especially in food processes.

Summary: This study investigates the life cycle and metabolome of the pathogenic fungus Fusarium graminearum, which has significant impacts on agriculture and human health. A previously unknown polyketide from the PKS2 gene cluster was identified and named fugralin A and B. Functional characterization showed that these compounds are not produced during infection and do not affect pathogenicity or visual growth. The compounds are volatile, suggesting potential functions for further investigation.

Summary: Orchids depend on mycorrhizal fungi for germination, and this study found that different species and ages of Tulasnella fungi affect the germination of Thelymitra adorata. Younger cultures showed higher germination rates, and T. subasymmetrica was able to germinate T. adorata, potentially expanding its conservation options.
