The deviation of conventional fungal niches is an important factor in the implications of hidden fungal diversity and global fungal numbers. The Xylariomycetidae (Sordariomycetes, Ascomycota), which is also referred to as xylarialean taxa, has a wide range of species that demonstrate a high degree of variation in their stromatic characteristics, showing either conspicuous or inconspicuous forms. In this study, samples were collected while focusing on temporal and spatial parameters and substrate characteristics. Based on internal transcribed spacer (ITS), 28S large subunit rDNA (LSU), RNA polymerase II second largest subunit (RPB2), and β-tubulin (TUB2) multigene phylogeny and morphology, five new species are introduced as Muscodor brunneascosporus, M. lam-phunensis (Xylariaceae), Nigropunctata hydei, N. saccata (Incertae sedis), and Xenoanthostomella parvispora (Gyrotrichaceae). Plant substrates in the early stages of decay and attached to the host were feasible sample niches, with an emphasis on the collection of inconspicuous, hidden xylarialean species. The appearance of inconspicuous saprobic xylarialean forms during the rainy season may be linked to the change in nutritional mode, from endophytic mode during the dry season to saprobic in the wet. Therefore, it would be fascinating to concentrate future research on how seasonal fluctuations affect nutritional mode shifts, especially in northern Thailand, which would provide the optimal spatial characteristics. In order to establish a comprehensive linkage between endophytic and sapro-bic modes, it is imperative to have a substantial representation of endophytic isolate sequences resembling inconspicuous xylariaceous fungi within publicly accessible databases.

Sooty mold is a common fungal foliar epiphyte that can significantly impact agricultural crops. In this study, we found four different species of sooty molds belonging to Capnodiaceae occurring on different plants in northern Thailand viz. Broussonetia papyrifera, Carica papaya, Mangifera indica, Manihot esculenta, and Rosa × damascene. These hosts showed dark brown mycelia covering their leaves. Phylogenetic analyses using a combination of LSU, ITS, tef-1α, and rpb2 sequence data showed that the newly obtained sequences belong to Capnodium coartatum, Ca. gamsii, Conidiocarpus caucasicus, and Phragmocapnias betle. The morphological characteristics of these four species concurred with the phylogenetic results. Notably, these four species are reported as new host records. Additionally, we validate Ca. paracoartatum sp. nov., and synonymize Co. asiaticus and Co. siamensis under Co. caucasicus based on morphological and phylogenetic analyses.

... Some species of endophytic fungi can activate host defense mechanisms against pathogens, such as fungi, bacteria, and viruses, as well as insects and nematodes, thereby acting as biological control agents (Hardoim et al., 2015;Kumar et al., 2019). Induratia species, including the strains evaluated in this study, have been reported to produce VOCs, which have antifungal properties against various phytopathogenic fungi causing common bean diseases such as anthracnose, white mold, and angular leaf spot diseases (Hongsanan et al., 2015;Macías-Rubalcava et al., 2010;Monteiro et al., 2017;Mota et al., 2021;Strobel, 2020;Strobel, 2018Strobel, , 2006. Considering our results and those published by Mota et al. (2021), some strains of Induratia could have significant potential to enhance common bean production and control disease in this crop. ...

Common bean (Phaseolus vulgaris L.) is a leguminous species of great economic and nutritional importance worldwide, and thus the development of management strategies to promote plant growth and increase grain yield of legumes is of great interest to farmers. The growth-promoting effects of the symbiosis of endophytic microorganisms in plants have been exploited in several crops. This study investigated the effects of Induratia sp. endophytic fungi on the growth and grain yield of seed-inoculated common bean plants. The experiments were conducted in a greenhouse during two growing seasons using a randomized complete block design with three replicates. Growth and yield-related parameters such as plant height, root length, leaf index, number of days for flowering, number of pods per plant, number of grains per pod, mass of 100 grains, and grain yield were evaluated. The grain yield of plants inoculated with Induratia coffeana strains CML 4018 and CML 4020 and Induratia sp. strain CML 4015 increased by 52.5%, 48.9%, and 56.4% compared to the non-inoculated control, respectively. Seed inoculation of common bean plants with endophytic fungi species of the genus Induratia showed a beneficial interaction as indicated by the recorded increase in grain yield. The present pioneering study could provide the means for developing crop management strategies for enhancing common bean crop productivity.

Induratia spp. fungi have been poorly evaluated for their non-volatile secondary metabolites. In the present work, we evaluated the effects of non-volatile secondary metabolites released into the culture medium by Induratia spp. upon toxic alterations induced by Bothrops spp. venoms. B. atrox venom phospholipase was inhibited by Induratia spp. around 12 and 16%. The extracts of the two strains inhibited 12–25% of the hemolysis induced by B.moojeni venom. Thrombolysis was inhibited by 30–60% by the compounds present in both extracts. The coagulation induced by B. moojeni venom was prolonged by 26–41 s by the action of the extracts of I. coffeana. The fungal extracts did not exert any cytotoxic effect, nor did they induce any alteration in the other evaluated substrates show the potential use of non-volatile metabolites produced by the fungi evaluated as enzyme modulators, especially for proteases with a fundamental role in human hemostasis.
... has been widely reported as plantassociated fungi, where M. scabiosae was first isolated from Scabiosa sp. flower (Hongsanan et al. 2015;Tennakoon et al. 2016).

Sibero MT, Pribadi R, Larasati SJH, Calabon MS, Sabdono A, Subagiyo S, Frederick EH. 2021. Diversity of sponge-associated fungi from a mangrove forest in Kemujan Island, Karimunjawa National Park, Indonesia. Biodiversitas 22: 5695-5605. Plenty of studies have reported interesting biological properties and bioactive compounds from sponge-associated fungi in Indonesia. However, only a few studies consider their biodiversity. Most of the studies collected the sponge from the coral reef ecosystem and barely reported from the mangrove ecosystem. This study aimed to discover the biodiversity of sponge-associated fungi from a mangrove ecosystem using a DNA barcoding approach. Five mangrove-associated sponges were collected from a tidal mangrove forest in Kemujan Island, Karimunjawa National Park, Indonesia. In total, we isolated 56 sponge-associated fungi, which consisted of seven genera in the phylum Ascomycota (77.78%), one genus in the phylum Basidiomycota (11.11%), and one genus in the phylum Mucoromycota (11.11%). Trichoderma (n: 15, 26.79%), Aspergillus (n: 13, 23.21%) and Fusarium (n: 12, 21.45%) were the top three dominant genera. In addition, based on the association of fungi to its sponge hosts, Aspergillus, Aureobasidium, Fusarium, and Trichoderma are sponge-generalists; Absidia and Pestalotiopsis are sponge-associates; while Lasiodiplodia, Montagnula, and Wallemia are sponge-specialist.

Fungi belonging to the genus Induratia are endophytes that have received considerable attention because of the production of natural bioactive secondary metabolites, such as volatile compounds, with antimicrobial activity. In this study, we distinguished I. coffeana and Induratia sp. isolated from Coffea arabica in Brazil based on three-loci phylogeny, ITS, RPB2, and TUB2. The Induratia isolates showed high morphological plasticity and produced different volatile organic compounds, indicating that these compounds might not be correlated with their phylogenetic assignment. However, PLS-DA was able to discriminate Induratia isolates into three different clusters: one associated with I. coffeana and two with Induratia sp. Induratia isolates showed biofumigant activity against Botrytis cinerea with emphasis on I. coffeana (CML 4019), which inhibited the pathogenic fungus in postharvest strawberries. Nematicidal activity against Meloidogyne incognita was also observed in filtrates and volatile compounds produced by Induratia isolates. Moreover, we observed that I. coffeana (CML 4019) metabolites showed antibacterial activity against Staphylococcus aureus, Enterococcus faecalis, and E. faecium and that extracts of seven other Induratia isolates reduced the pre-formed biofilm of Staphylococcus aureus and Staphylococcus epidermidis.
