Neocamarosporium species are typically halotolerant, being commonly found in saline environments like saline water, hypersaline soils and especially in association with halophytes. Several isolates were obtained from saline water, dead leaves of the seaweed Zostera noltii and live tissues of the halophyte Halimione portulacoides. Phylogenetic analysis based on ITS sequence data placed these isolates into three clades within the genus Neocamarosporium distinct from the currently known species. Isolates from each clade showed clear differences in conidial morphology. Three new species N. aestuarinum sp. nov., N. endophyticum sp. nov. and N. halimiones sp. nov. are described and illustrated. Our results show that the salt marsh plant H. portulacoides harbours a high diversity of Neocamarosporium species.

Auricularia is a key genus among edible macrofungi, sourced as either wild or cultivated mushrooms. Auricularia species are utilized as nutrient-rich foods and medicinal resources, with particular prominence in Traditional Asian Medicine. Cultivated Auricularia species can be grown under a wide range of conditions, allowing for production volumes worldwide. Although Auricularia species are used predominantly within the food industry, there is strong potential for their use in the production of therapeutic drugs, thus making it necessary to identify relevant bioactive compounds and further our understanding of its pharmacological properties. Carbohydrates are the major nutritional constituent of edible Auricularia species in addition to proteins, fat, fibre, ashes vitamins and minerals. This review discusses polysaccharides as one of the major active compounds found in edible Auricularia species in relation to their nutritional value, extraction methods, and pharmacological properties. Current methods of evaluating the pharmacological effects of compounds derived from Auricularia include in vitro assays, in vivo animal models, as well as several human clinical trials. Potential medical applications for these compounds include the production of novel therapeutic drugs for treating diseases such as cancer, diabetes, and cardiovascular disorders.

It has been suggested that the genus Muscodor should be rejected, while many new species recently introduced are based on chemical profiles of volatile organic compounds and insufficient phylogenetic analyses. The ITS rRNA gene was used for identification of Muscodor species, but has limitations. A four-locus (ITS rRNA, 28S rRNA, RPB2 and TUB1 gene) combined phylogenetic tree has been reconstructed in the current study to confirm that the genus Muscodor is phylogenetically distinct from other closely related genera. A new Muscodor species named Muscodor yunnanensis is described based on phylogenetic analyses and culture characteristics.

This is the second in a series of papers on lignicolous freshwater fungi from China. In this paper, eight fresh collections of asexual morphs of Distoseptispora, isolated from submerged wood in northwestern Yunnan Province, China, are characterized based on morphological characters and phylogenetic analyses of combined ITS, LSU, RPB2 and TEF1α sequence data. Four new Distoseptispora species (D. cangshanensis, D. obpyriformis, D. rostrata and D. submersa) are introduced, described and illustrated, with notes on their taxonomy and phylogeny. Newly generated molecular data of Distoseptispora fluminicola is also provided. We also provide a unified method for studying lignicolous freshwater fungi to standardize the findings of future Asian studies. Key word – Asexual fungi – Methodology – Phylogeny – Sordariomycetes – Taxonomy Introduction Lignicolous freshwater fungi play an important role in nutrient and carbon cycling, biological diversity and ecosystem functioning in freshwater ecosystems (Palmer et al. 1997, Yuen et al. 1998, Bucher et al. 2004, Vijaykrishna et al. 2005, Hyde et al. 2016a). There have been some studies on lignicolous freshwater fungi in Yunnan Province, China (Cai et al. 2002, Luo et al. 2004, 2016, 2017, 2018, Liu et al. 2015, Su et al. 2015, 2016, Zhu et al. 2016) and in this paper, we deal with the genus Distoseptispora K.D. Hyde, McKenzie & Maharachch. which belongs to Distoseptisporaceae, Sordariomycetes. The family Distoseptisporaceae K.D. Hyde & McKenzie was introduced by Su et al.

An updated analysis of myxomycete diversity in Costa Rica is provided herein as a product of an extensive data mining-based study intended to normalize the information on myxomycetes from that country. Within the context of the Mesoamerican Biodiversity Hotspot, the 242 species of myxomycetes are reported herein demonstrated the potential of this area for diversity-based studies. For the construction of the updated species list, a thorough analysis that included examination of vouchers and a literature review has been carried out, and some species previously included in other works have been rejected due to inconsistencies or misidentification. The present contribution is essential to address the Wallacean shortfall within Mesoamerica and important for providing updated data on microorganisms in the context of regional biodiversity monitoring.

In this paper, we show that a Talaromyces stipitatus isolated as an endophyte from the root of the mangrove tree Avicennia marina, produces salt-tolerant chitinase and chitosanases. The endophyte is halotolerant and produces these chitin modifying enzymes even in the presence of a high concentration of NaCl in the growth medium. The chitosanases produced could act on chitosans of low, medium and high degrees of acetylation. The presence of NaCl influenced the production of isoforms of chitinase and chitosanase by the endophyte. The chitinase activity was not altered much by NaCl concentration.

Many plant–ant interactions are considered mutualisms. In Mallotus paniculatus (Euphorbiaceae) (also known as Turn-in-the-wind), the extrafloral nectaries (EFNs) on the base of the leaf laminas can produce sugar-rich secretions to attract ants as effective agents against herbivores or plant competitors. Growing evidence reveals that microorganisms are important “hidden players” in insect–plant interactions. Understanding which microorganisms act as such third-party species and how they operate is a major challenge in the study of mutualistic interactions. In this study, we showed that two dominant fungal species, the yeast Jaminaea angkorensis and the hyphal fungus Gibellulopsis nigrescens both from EFNs and the interiors of bodies of the ant Pheidole megacephala (Formicidae) on their own were sufficient for ant attraction. Our results also revealed that different fungal species on the host plant influenced ant behavior differently. These results can be applied in agriculture to increase ants or herbivore predators to protect plant hosts using fungal baits. Moreover, they indicate that fungal odors represent the critical signal to establish the plant–microbe–insect interactions. The traditional plant– defender concept must be updated to include the role of microorganisms.

A series of functional variables, including biomass and hymenial area, were obtained for more than 4800 individual macrofungal sporocarps and correlated with a set of ecological parameters characterizing soil, climate and forest structure in four different forest types of Costa Rica. The idea behind this project was to document macrofungi over a three-year period with the objective of generating a dataset intended to document sporocarp variability and association with forest characteristics. In the context of climate change, habitat degradation and tropical forest fragmentation, studying fungi from an ecological perspective can provide crucial elements of analysis to weigh their relevance in tropical systems and to understand the potential threats to fungal populations. Our results showed high variability in the functional variables over the period of study, but suggest that such variability is partially induced by macroclimatic events in which forests with a higher percentage of mycorrhizal fungi seemed to be more sensitive. Overall, the ratio of hymenial area/biomass and pileus diameter were found to be significantly correlated with several ecological parameters in the studied forest types. However, the association of the former with ecological reproductive strategies makes such variable a good parameter to use for the monitoring of fungal dynamics in the studied tropical forests. The potential application of the latter in the framework of climate change and forest degradation studies is relevant since fungi are essential organisms in tropical ecosystems.
