    Most species of Dothiora are known from the dead parts of various host plants as saprobic fungi in terrestrial habitats occurring in tropical and temperate regions. In the present study, samples of Dothiora were collected from dead twigs and branches of Capparis spinosa, Rhaponticum repens, and an unknown angiosperm plant from the Tashkent and Jizzakh regions of Uzbekistan. Multi-gene phylogenetic analyses based on a combined ITS, LSU, SSU, TEF1, and TUB2 sequence data revealed their taxonomic positions within the Dothideaceae. Three new species of Dothiora, namely, Dothiora capparis, Dothiora rhapontici, and Dothiora uzbekistanica were proposed by molecular and morphological data. Likewise, the phylogenetic relationship and morphology of Dothiora are discussed. In addition, we provide a list of accepted Dothiora species, including host information, distribution, morphology descriptions, and availability of sequence data, to enhance the current knowledge of the diversity within Dothiora

Suwannarach, SDBR-CMU481, a dried cultured on PDA, culture ex-type SDBR-CMU481, preserved in a metabolically inactive state.</p> <p> Description:—Isolated from rock in terrestrial habitat. Sporulation on PDA after incubation at 25°C for two months. <i>Conidiomata</i> were observed under a stereo microscope, 70–175 µm high, 60–145 µm diam., pycnidial, globose to subglobose, scattered or aggregated into clusters, immersed to erumpent, dark brown to black, ostiolate, covered with white mycelia. <i>Conidiomata wall</i> 8–44 µm wide, composed of thick-walled cells of <i>textura angularis</i>, brown to dark brown. <i>Conidiophores</i> reduced to conidiogenous cells. <i>Conidiogenous cells</i> 8–19 × 2–6 µm, hyaline, smooth, ampulliform to subcylindrical, arising from the inner cavity of the conidioma wall. <i>Conidia</i> 3–4 × 2–3 µm, hyaline, solitary, subglobose to broadly ellipsoid, aseptate, smooth-walled.</p> <p>Culture characteristics:—Colonies on PDA reaching 32–35 mm diam. after 4 weeks at 25°C, flattened, wrinkled, with entire edges; colony from above, greyish-white at the center, greyish red at the margin, produced a soluble red pigment; from below: greyish ruby at the center, dark ruby at the margin. Colonies on MEA reaching 23–26 mm diam. after 4 weeks at 25°C, flattened, with entire edges, slightly concentric ring in the middle; colony from above, greyish-white; from below: brown, with white at the margin, dark grey in the middle, radiated with concentric sectors, producing light brown pigmentation around the colony. Colonies on CMD reaching 32–35 mm diam. after 4 weeks at 25°C, flattened, with entire edges, concentric ring; colony from above, light brown in the center, yellowish-white at the margin; from below: light brown in the middle, with white to cream at the margin, strongly radiated with concentric sectors, producing light brown pigmentation around the colony.</p> <p>Additional specimen examined:— THAILAND, Lamphun Province, Mueang Lamphun District, Sribuaban Subdistrict, Chiang Mai University Hariphunchai Campus, 18°32′11′′N, 99°07′30′′ E, isolated from a rock of a natural forest, 15 November 2022, N. Suwannarach, SDBR-CMU482, a dried cultured on PDA, living culture SDBR-CMU482.</p> <p> Notes:—Morphologically, the new species fitted well with the asexual morph of the genus <i>Anteaglonium</i>. The growth of <i>A. saxicola</i> at 25°C on MEA was slower than <i>A. parvulum</i> and <i>A. thailandicum</i> (13–16 and 23 mm, respectively, after incubation for 7 d) (Jayasiri <i>et al.</i> 2016), while it displayed faster growth than <i>A. rubescens</i> (11–13 mm after incubation for 2 months) (Jaklitsch <i>et al.</i> 2018). Remarkedly, <i>A. saxicola</i> displayed faster growth than <i>A. rubescens</i> on PDA and CMD (10 and 5–6 mm, respectively) after incubation at 25°C for four weeks. Based on the asexual morph characteristics, <i>A. saxicola</i> differs from <i>A. parvulum</i>, <i>A. rubescens</i>, and <i>A. thailandicum</i> by its longer conidiogenous cells (TABLE 2) (Jayasiri <i>et al.</i> 2016, Jaklitsch <i>et al.</i> 2018). Moreover, <i>A. saxicola</i> can be distinguished from <i>A. rubescens</i> by its wider conidiomata wall (Jaklitsch <i>et al.</i> 2018). However, due to the indeterminate morphological characteristics of the asexual morphs of <i>A. abbreviatum</i>, <i>A. brasiliense</i>, <i>A. globosum</i>, <i>A. gordoniae</i>, <i>A. latirostrum</i>, <i>A. lusitanicum</i>, and <i>A. queenslandicum</i>, we cannot compare their microscopic structures (Mugambi & Huhndorf 2009, Almeida <i>et al.</i> 2014, Jayasiri <i>et al.</i> 2019, Tan <i>et al.</i> 2022, Tan & Shivas 2023).</p> <p> Phylogenetically, <i>Anteaglonium saxicola</i> is closely related to <i>A</i>. <i>lusitanicum</i> and <i>A. parvulum</i>; however, the genetic distance of the nrLSU and ITS sequences of <i>A. saxicola</i> to <i>A. lusitanicum</i> was 0.93 and 5.5% (8/867 and 27/491 bp including gaps), respectively. Furthermore, the genetic distance of nrLSU and ITS sequences also indicated that <i>A. saxicola</i> differs from <i>A. parvulum</i> MFLUCC 10-0928, MFLUCC 11-0511, MFLUCC 11-0374, and MFLUCC 11-0380 by having 1.35% and 6.97% (11/817 and 34/488 bp including gaps), 1.24% and 5.92% (10/805 and 29/490 bp including gaps), 1.24% and 6.31% (10/804 and 31/491 bp include gaps), and 1.49% and 6.12% (12/804 and 30/490 bp including gaps), respectively.</p>Published as part of <i>Suwannarach, Nakarin, Kumla, Jaturong, Khuna, Surapong, Thitla, Tanapol, Senwanna, Chanokned, Hongsanan, Sinang & Lumyong, Saisamorn, 2023, Anteaglonium saxicola (Anteagloniaceae, Pleosporales), a new species isolated from rocks in northern Thailand, pp. 75-84 in Phytotaxa 629 (1)</i> on pages 79-81, DOI: 10.11646/phytotaxa.629.1.6, <a href="http://zenodo.org/record/10254797">http://zenodo.org/record/10254797</a&gt

    Multi-Gene Phylogeny and Morphology Reveal Haplohelminthosporium gen. nov. and Helminthosporiella gen. nov. Associated with Palms in Thailand and A Checklist for Helminthosporium Reported Worldwide

    No full text
    Palms (Arecaceae) are substrates for a highly diverse range of fungi. Many species are known as saprobes and many are important plant pathogens. Over the course of our studies of micro-fungi from palms in Thailand, two new taxa were discovered. Morphological characteristics and phylogenetic analyses of combined ITS, LSU, SSU, and tef1-α sequence data revealed their taxonomic positions within Massarinaceae. There are currently ten genera identified and accepted in Massarinaceae, with the addition of the two new genera of Haplohelminthosporium and Helminthosporiella, that are introduced in this paper. Each new genus is provided with a full description and notes, and each new taxon is provided with an illustration for the holotype. A list of identified and accepted species of Helminthosporium with morphology, host information, locality, sequence data, and related references of Helminthosporium reported worldwide is provided based on records in Species Fungorum 2021. This work provides a micro-fungi database of Haplohelminthosporium, Helminthosporiella, and Helminthosporium which can be modified and validated as new data come to light

    Identification and Pathogenicity of Paramyrothecium Species Associated with Leaf Spot Disease in Northern Thailand

    No full text
    Species of Paramyrothecium that are reported as plant pathogens and cause leaf spot or leaf blight have been reported on many commercial crops worldwide. In 2019, during a survey of fungi causing leaf spots on plants in Chiang Mai and Mae Hong Son provinces, northern Thailand, 16 isolates from 14 host species across nine plant families were collected. A new species Paramyrothecium vignicola sp. nov. was identified based on morphology and concatenated (ITS, cmdA, rpb2, and tub2) phylogeny. Further, P. breviseta and P. foliicola represented novel geographic records to Thailand, while P. eichhorniae represented a novel host record (Psophocarpus sp., Centrosema sp., Aristolochia sp.). These species were confirmed to be the causal agents of the leaf spot disease through pathogenicity assay. Furthermore, cross pathogenicity tests on Coffea arabica L., Commelina benghalensis L., Glycine max (L.) Merr., and Dieffenbachia seguine (Jacq.) Schott revealed multiple host ranges for these pathogens. Further research is required into the host–pathogen relationship of Paramyrothecium species that cause leaf spot and their management. Biotic and abiotic stresses caused by climate change may affect plant health and disease susceptibility. Hence, proper identification and monitoring of fungal communities in the environment are important to understand emerging diseases and for implementation of disease management strategies
