    Abstract Avocado production is restricted globally by the anthracnose disease caused by Colletotrichum species. In Thailand, anthracnose symptoms can be found on avocado leaves and fruits, and it is an important postharvest disease, reducing the shelf life of the fruits and causing huge economic losses. Avocado leaves and fruits showing anthracnose disease were collected from Chiang Rai province, located in northern Thailand, and the Colletotrichum species isolated from the samples were identified based on morphological examination and multigene phylogenetic analyses. Phylogenetic analyses using five loci (ITS, ACT, CHS‐1, GAPDH and TUB2) coupled with the morphology of 11 isolates showed that they belonged to four known species of Colletotrichum. Colletotrichum endophytica, C. fructicola and C. siamense are illustrated as new geographical records, and C. henanense is characterized as a new host record. Furthermore, the pathogenicity of these species in avocado fruits and leaves (West Indian variety) has been proven. In addition, this study provides further evidence for the synonymization of C. pandanicola and C. parvisporum with C. siamense.

    Abstract Mucor species are a group of common soil-borne fungi, known to cause infections on humans and animals, interfere in food production, and act as useful agents in biotechnological applications. This study reports one new Mucor species, M. yunnanensis, which was found to be fungicolous on an Armillaria sp. from southwest China. Further, M. circinelloides on Phlebopus sp., M. hiemalis on Ramaria sp. and Boletus sp., M. irregularis on Pleurotus sp., M. nederlandicus on Russula sp., and M. yunnanensis on Boletus sp. are reported as new host records. Mucor yunnanensis and M. hiemalis have been collected from Yunnan Province in China, whereas M. circinelloides, M. irregularis, and M. nederlandicus have been collected from Chiang Mai and Chiang Rai Provinces in Thailand. All the Mucor taxa reported herein were identified based on both morphology and phylogenetic analyses of a combined nuc rDNA internal transcribed spacer region ITS1-5.8S-ITS2 (ITS) and partial nuc 28S rDNA (28S) sequence matrix. Comprehensive descriptions, illustrations, and a phylogenetic tree are provided for all the taxa reported in the study to show the placements of taxa, and the new taxon is compared with its sister taxa.

    Abstract Appressoria are specialized structures formed by certain phytopathogenic fungi during the early stages of the infection process. Over the years, significant advancements have been made in understanding the formation, types, and functions of appressoria. Besides being formed primarily by fungal pathogens, many studies have reported their occurrence in other life modes such as endophytes, epiphytes, and saprobes. In this study, we observed the formation of appressoria in fungal genera that have been found associated with leaf spots and, interestingly, by a saprobic species. We used morphological descriptions and illustrations, molecular phylogeny, coalescent-based Poisson tree processes (PTP) model, inter- and intra-species genetic distances based on their respective DNA markers, and Genealogical Concordance Phylogenetic Species Recognition Analysis (GCPSR) to establish a new species (

    Abstract Entomopathogenic fungi comprise an ecologically important group of specialized pathogens infecting other fungi, invertebrates, and plants. These fungi are species-rich with high diversity and broad distribution worldwide. The majority of entomopathogenic fungi belong to clavicipitoids, which consist of the hypocrealean families, Clavicipitaceae, Cordycipitaceae, Ophiocordycipitaceae, and Polycephalomycetaceae. The latter is a newly established entomopathogenic family that recently separated from the family Ophiocordycipitaceae to accommodate the genera,

    Abstract AbstractPleocatenata, a new genus, is introduced with its type species, Pleocatenata chiangraiensis, which was isolated from withered twigs of two medicinal plants, Clerodendrum quadriloculare (Blanco) Merr (Verbenaceae) and Tarenna stellulata (Hook.f.) Ridl (Rubiaceae) in northern Thailand. The genus is characterized by mononematous, septate, brown or dark brown conidiophores, monotretic conidiogenous cells and catenate, obclavate, olivaceous to blackish brown conidia. Phylogenetic analysis of combined LSU, SSU, tef1-α, rpb2 and ITS sequence data showed Pleocatenata forms a distinct phylogenetic lineage in Pleosporales, Dothideomycetes. Therefore, we treat Pleocatenata as Pleosporales genera incertae sedis based on morphology and phylogenetic analyses. Descriptions and illustrations of the new taxa are provided, and it is compared with morphologically similar genera.

    Abstract AbstractCoffee is one of the most important cash crops in Yunnan Province, China. Yunnan is ranked as the biggest producer of high-quality coffee in China. During surveys of microfungi from coffee plantations in Yunnan, six fungal strains that resemble Nigrogranaceae were collected. Multi-gene analyses of a combined SSU-LSU-ITS-rpb2-tef1-α sequence data matrix were used to infer the phylogenetic position of the new species in Nigrograna while morphological characteristics were used to deduce the taxonomic position of the new species. Six fungal strains isolated from decaying branches of Coffea arabica represent three new saprobic species in Nigrograna. The three new species, N. asexualis, N. coffeae, and N. puerensis, are described with full (macro and micro characteristics) descriptions, illustrations, and a phylogenetic tree that shows the phylogenetic position of new taxa.
