Three pleosporalean fungi were collected from Qujing, Yunnan, China. Morphological characterisation and multigene phylogenetic analyses confirmed that these fungi belong to the order Pleosporales but in different families. Alternaria alternata sensu lato (Pleosporaceae) is reported herein as a new geographical record from southwestern China. Neocucurbitaria juglandicola (Cucurbitariaceae) is reported from Magnolia grandiflora as a new host and country record. Phragmocamarosporium qujingensis (Lentitheciaceae) is reported from Vitis sp. for the first time. Morphological data, photographic illustrations and descriptions are provided along with the phylogenetic trees.

An induratia–like fungus was collected in Thailand from a deadwood piece of an unidentified plant. Phylogenetic analyses based on ITS, LSU, rpb2, and β-tubulin sequence data and morphological characteristics showed that the fungus is Induratia coffeana. Induratia coffeana differs from I. ziziphi, I. thailandica and I. apiospora by its 2–celled ascospores with equal divisions. Full description, illustrations, and a phylogenetic tree to show the placement of I. coffeana are provided. Induratia coffeana is reported herein as a new record for Thailand based on its sexual morph.

In this study, three species of Astrocystis were collected from bamboo culms in Guizhou and Yunnan Provinces in China. Morphological characteristics and phylogenetic analyses (based on ITS, rpb2, β-tubulin and α-actin gene regions) supported the proposal of two new species viz., Astrocystis pseudomirabilis sp. nov. and A. tessellati sp. nov. and a new record of A. sublimbata from China. Astrocystis pseudomirabilis can be distinguished from A. mirabilis by its larger stromata (0.64–0.83 × 0.38–0.52 mm vs. 0.4–0.6 × 0.2–0.5 mm) and larger ascospores (11–14 × 6–8 μm vs. 10–12 × 4.5–6 μm). Astrocystis tessellati differs from A. multiloculata by its smaller ascospores (16.2–19.2 × 7.2–9 μm vs. 19–25 × 7–11 μm).Astrocystis pseudomirabilis and A. tessellati form two distinct clades within Astrocystis.

The wild edible mushroom Macrocybe gigantea is widely consumed as one of the prime seasonal delicacies in the tropical and subtropical regions of the world. In this study, M. gigantea was identified through morphological and phylogenetic analyses. Spawn production and cultivation parameters of M. gigantea were investigated for the first time in Sri Lanka. The mycelial growth was observed in potato dextrose agar medium, while paddy grains were used for spawn production. A mixture containing rubber sawdust (100 kg), rice bran (18 kg), CaCO3 (2.5 kg), gypsum (1 kg), and MgSO4 (0.35 kg) was tested as a substrate for colonization bags. In addition, gene sequence-data, proximate analysis, energy value, and mineral elements of cultivated M. gigantea were studied. Mycelia in mushroom growth bags were cultivated under the temperature range of 27–30 ℃ and relative humidity of 60 %. Three weeks after inoculation, the primordia appeared and it took four additional days until the occurrence of young fruit bodies. A second flush was harvested 3 weeks after the first. Proximate analysis, energy value and mineral element analysis were recorded as 85.3 % moisture, 0.8 % ash, 1.6 % fat, 2.3 % protein, 10.0 % carbohydrate, 0.28 % potassium (K), 0.00064 % iron (Fe), 0.0024 % sodium (Na), and energy 63.6 kcal/100g. This study provides valuable information concerning the cultivation and nutritional composition of M. gigantea in Sri Lanka.

Multiple fungal pathogens infect economically important fruits, thereby affecting their quality and marketability. Previous research showed that some fungal pathogens that can infect the stems might infect the fruit but show a different symptom. To determine the causal pathogen of a fruit disease of Selenicereus monacanthus(Dragon fruit), we used a combination of fungal pathology characterization and molecular biology techniques. This paper presents the pathogenicity of Neoscytalidium dimidiatum MBDF36C to S. monacanthus resulting in brown rot and canker on fruits and stem, respectively. The paper also demonstrates the in vitro inhibition of N. dimidiatum MBDF36C by chemicals, including a bio-fungicide containing Bacillus subtilis. At seven days post-inoculation, we observed severe browning on N. dimidiatum MBDF36C-inoculated fruits but not on stems. Stems exhibited canker-like symptoms. The same funguswas re-isolated from both inoculated diseased fruits and stems, thereby confirming Koch’s postulates. The pathogen was identified as N. dimidiatum based on its morphology, cultural characteristics, and sequences of the partial ß-tubulin gene. In vitro growth of N. dimidiatum MBDF36C was also completely inhibited by a bio-fungicide containing B. subtilis, isoprothiolane, and mancozeb. This study is the first report of N. dimidiatumcausing brown fruit rot of dragon fruit in the Philippines. This information could impact the current postharvest fruit handling operations and future studies on dragon fruit disease management.

Fungal spores, like pollen, are identified as sources of allergens, yet fungal spore morphology, unlike pollen morphology, has not been correlated with allergenicity. In this study, we listed allergenic fungi reported from published literature and gathered information about their spore morphologies including the species’ lifestyle, the ability to produce mycotoxins, and the types of hypersensitivity reactions they induced. We tested the association of these spore traits with the hypersensitivity reaction through correspondence analysis with Chi-square as the measure of distance. Our research listed a total of 158 species of allergenic fungi belonging to 82 genera and 30 taxonomic orders. Most of the species (n = 122) elicited a Type I hypersensitivity reaction while 33 species had more than one hypersensitivity type (Types I-III-IV). The most common allergenic fungi belong to the genus Alternaria (41 species). Two fungal taxa commonly found in spoiled food, Penicillium (9 species) and Aspergillus (8 species), were also listed as allergenic. We did not find any strong correlation between allergenic reaction with the following spore traits: shape, texture, color, size, appendages, and with the type of spores, presence of mycotoxins, and the species lifestyle. However, spore length and width were positively associated with hypersensitivity reaction. Allergenic fungi with short and/or narrow spores can likely cause multiple types of hypersensitivity reactions while fungi with large and/or wide spores can induce either Type I or Type III hypersensitivity reaction. Our research study provides interesting insights into the role of fungal spore morphologies in human allergenicity.

The role of fungi in both natural and managed ecosystem processes is unequivocal with mycotaxa being key drivers of soil, plant and animal health. Recent advances in DNA-based species identification and classification have enforced mycologists to update national checklists for proper exploitation of fungal traits and functions. However, in some countries like Pakistan, a comprehensive checklist of fungal diversity, distribution, and their host range is still lacking. Herein, we summarize novel fungal species (including both macro- and micro-fungi) for the first time from distinct geographical locations of Pakistan. A total of 742 novel fungal species in 7 phyla have been reported in Pakistan since 1947, including 136 ambiguous species (as a result of cryptic species, taxonomy revisions, and lack of DNA sequence data) and 113 species with DNA sequence data. The compilation of the fungal name list provides an overview of the currently known fungal taxa in Pakistan and enables the assessment of the knowledge gap on the fungal biodiversity in comparison to the rest of the world. The current checklist will serve as a foundation for new fungi names to be added in the future and can be used as a reference by mycologists to retrieve fungal species from existing culture banks in Pakistan mentioned on the website, www.fungiofpakistan.com, to exploit their functional traits in the food industry, health sectors and for sustainable agriculture in Pakistan.

This study resolves the phylogenetic position of an anamorphic synnematous genus, Gangliostilbe,(typified by G. indica) collected from the Northern Western Ghats of India. Gangliostilbe can be distinguished based on its erect synnemata, simple, dark-coloured, well-defined stalk, a subglobose to clavate head, and solitary, acrogenous, brown, phragmoconidia having three or more septa that secede through gangliar conidiogenesis. Phylogenetic analysis based on ITS and LSU sequence data supported the placement of Gangliostilbe in Xenospadicoidaceae (Xenospadicoidales). Gangliostilbe is the only genus in Xenospadicoidaceae having synnematous conidiomata and gangliar conidiogenesis.
