... Tetraplosphaeriaceae was introduced by Tanaka et al. [1] to accommodate five tetraploa-like genera, viz., Polyplosphaeri, Pseudotetraploa, Quadricrura, Tetraplosphaeria (type), and Triplosphaeria. In a reassessment conducted by Hyde et al. [2], Tetraplosphaeria was treated as a synonym of Tetraploa, which had previously been applied to the asexual state. ...
... Recently, Zhang et al. [10] introduced one additional new genus, Pseudopolyplosphaeria, which was collected from karst landscapes of Guizhou Province on dead bamboo culms. Hyde et al. [2] and Dong et al. [4] have provided a taxonomic key for several genera within Tetraplosphaeriaceae. Tetraplosphaeriaceae is characterized by massarina-like sexual morphs with almost hyaline, 1(-3)-septate ascospores and/or tetraploa-like asexual morphs with several setose appendages [1]. The majority of species within the family have been recorded as saprobic, primarily associated with bamboo [1,11,12]. ...

Species within Tetraplosphaeriaceae have been frequently documented in recent years with the extensive investigations of microfungi along a latitudinal gradient from north to south in the Asian/Australian region. Both bamboo substrates and freshwater habitats serve as extensive reservoirs, hosting a rich diversity of fungi that exhibit broad geographical distributions. The most common fungi in these two environments are generally distributed in distinct families. However, our statistics have revealed an intriguingly distinct preference of Tetraplosphaeriaceae species for inhabiting both bamboo substrates and freshwater habitats. The genera Pseudotetraploa (100%) and Triplosphaeria (100%) exhibit a strong preference, followed by Shrungabeeja (71%) and Quadricrura (67%). Our taxonomic and phylogenetic study of microfungi in southern China have identified four additional novel species, viz., Aquatisphaeria bambusae sp. nov., Pseudotetraploa phyllostachydis sp. nov., Pseudotetraploa yangjiangensis sp. nov., and Tetraploa submersa sp. nov. from bamboo substrates and freshwater habitats. In addition, Aquatisphaeria thailandica has previously been documented from freshwater habitats in Thailand; however, we have once again isolated this species from decaying bamboo substrates in Guangdong, China. The new findings substantiate our hypothesis that the preference of Tetraplosphaeriaceae species for colonizing bamboo substrates and freshwater habitats will be more evident through more extensive investigations conducted in such environments.
... Tetraplosphaeriaceae was introduced by Tanaka et al. (2009) with the type Tetraplosphaeria to accommodate five new genera, Polyplosphaeria, Pseudotetraploa, Quadricrura, Tetraplosphaeria and Triplosphaeria. Tetraplosphaeria was treated as a synonym of Tetraploa due to nomenclatural priority. ...

Monocotyledons are one of the important groups of flowering plants that include
approximately 60,000 species with economically important crops including coconut (Cocos nuciferanucifera), pineapple (Ananas comosus comosus), and rice (Oryza sativa sativa). Studies on these hosts are mainly focused on pathogenic fungi; only a f ew saprobic species have been reported. This study investigated the saprobic ascomycetes associated with coconut, pineapple, and rice in southern China and northern Thailand. Approximately 200 specimens were collected, and 100 fungal strains were isolated and identified to 77 species based on phylogenetic approaches and morphological characteristics. Among the 77 species, 29, 38, and 12 were found on coconut, pineapple, and rice, respectively, distributed in Dothideomycetes (41), Eurotiomycetes (one), and S ordariomycetes (35). Pseudomycoleptodiscus , Pseudosaprodesmium Pseudosetoseptoria, Pseudostriatosphaeria and
Pseudoteichospora are introduced as new genera and Anthostomella cocois, Apiospora ananas, Chromolaenicola ananasi, Epicoccum yunnanensis, Exserohi lum ananas, Hypoxylon cocois, Lasiodiplodia ananasi, Muyocopron chiangraiense, Myrmecridium yunnanense, Occultitheca ananasi, Periconia chiangraiensis, Placidiopsis ananasi, Pseudomycoleptodiscus ananas, Pseudosaprodesmium cocois, Pseudosetoseptoria oryzae, Pseudostriatosphaeria chiangraiensis,
Pseudoteichospora thailandensis, Savoryella chiangraiensis, Savoryella cocois, and Tetraploa oryzae are introduced as novel species. In addition, 51 species are reported as new hosts or geographical records, and six species are reported as new collections. Pseudopithomyces pandanicola and P. palmicola are synonymized under P. chartarum, P. diversisporus synonymized under P. atro olivaceus based on phylogenetic analyses and morphological characteristics.
Moreover, comprehensive checklists of fungi associated with coconut, pineapple, and rice are also provided.

... Tetraplosphaeria is the type genus, although Hyde et al. (2013) treated the genus as a synonym of Tetraploa. The massarina-like sexual morphs of Tetraplosphaeriaceae are characterised by immersed to superficial ascomata, cylindrical to clavate, short pedicellate asci, and narrowly fusiform to broadly cylindrical, septate, hyaline to pale brown ascospores, often surrounded with an entire sheath or appendage-like sheath (Tanaka et al. 2009;Hyde et al. 2013). The asexual morphs are tetraploa-like hyphomycetes, characterised by monoblastic conidiogenous cells, shortcylindrical to obpyriform conidia, composed of several columns at the conidial base with several setose appendages at the apex (Tanaka et al. 2009;Hyde et al. 2013). ...

Currently, nine genera are accepted in this family, Aquatisphaeria, Byssolophis, Ernakulamia, Polyplosphaeria, Pseudotetraploa, Quadricrura, Shrungabeeja, Tetraploa (=Tetraplosphaeria), and Triplosphaeria (Ariyawansa et al. 2015;Delgado et al. 2017;Pem et al. 2019;Dong et al. 2020;Li et al. 2021;Wijayawardene et al. 2022). ...
... All species of these Anthostomella-like genera were collected from bamboo. Most lineages of bambusicolous fungi tend to deviate from existing families found on other host plants, even though they have morphological similarities to other known fungal families (Tanaka et al., 2009). Another example of an Anthostomella-like fungal group on bamboo is Spirodecosporaceae, which has been determined to represent a phylogenetically distinct lineage within Xylariales, Sordariomycetes . ...
... Another example of an Anthostomella-like fungal group on bamboo is Spirodecosporaceae, which has been determined to represent a phylogenetically distinct lineage within Xylariales, Sordariomycetes . Similar examples are known for Dothideomycetes, namely, Tetraplosphaeriaceae (Tanaka et al., 2009), Bambusicolaceae (Hyde et al., 2013), and Occultibambusaceae (Dai et al., 2017). suggested that many novel lineages distantly related to known ascomycetous families and genera will be discovered from bambusicolous fungi. ...
This study investigates the phylogeny and taxonomy of Anthostomella-like fungi (Xylariales, Sordariomycetes) found in association with bamboo in Japan. Four new genera, Amphigermslita (including three new species, i.e., A. deformis, A. fusiformis, and A. pseudofusiformis), monotypic Crassipseudostroma (C. phyllostachydis) and Minuticlypeus (M. discosporus), and Pallidoperidium (two new species, P. exasperatum and P. paraexasperatum), and one known genus, Nigropunctata (one new species, N. complanata) are recognized and described. These five genera were found to constitute a distinct monophyletic lineage based on molecular phylogenetic analyses utilizing sequences of ITS and LSU nrDNA, rpb2, and tef1-α sequences. A new family, Pallidoperidiaceae, is proposed to accommodate these bambusicolous Anthostomella-like fungi. The identification of this lineage contributes to our understanding of the evolutionary relationships and classification of these bambusicolous fungi. It suggests that these five genera share a unique evolutionary history and possess shared morphological and ecological characteristics.
... The sexual morph of Bambusicolaceae is characterized by solitary or gregarious, immersed, semi-immersed to erumpent and conical or globose to subglobose ascomata; cylindrical to clavate asci with short furcate or rounded to obtuse pedicels; hyaline or yellowish to brown, slightly broad-fusiform or clavate to ellipsoidal, 1-to multi-septate ascospores and mostly with a gelatinous sheath (Dai et al. 2012, Hyde et al. 2013, Liu et al. 2015, Dong et al. 2020. The asexual morph of coelomycete Bambusicolaceae is characterized by cylindrical conidiogenous cells, and hyaline to brown, cylindrical to ellipsoidal conidia (Tanaka et al. 2009, Zhang et al. 2009, Dai et al. 2012, Hyde et al. 2013. ...
Macadamia integrifolia, one of the cash crops widely grown in the tropical and subtropical regions produces edible kernels with high oil content. Several fungal pathogens have been reported from this host, but very few studies on saprobic fungi have been carried out. As a part of our studies on saprobic fungi of edible nuts, dead branches of Macadamia integrifolia with fungal fruiting bodies were collected from Yunnan Province of China. Molecular analyses of combined SSU, ITS, LSU, RPB2, and TEF1-α sequence data showed that our collection belongs to Bambusicolaceae and forms a distinct branch with other genera in this family. Our collection fits well with the Bambusicolaceae, and morphology is similar to Palmiascoma but can be distinguished by molecular data. Therefore, we introduce our collection as Neopalmiascoma gen. nov., with N. macadamiae as the type species. A description, photo plate, and phylogenetic tree to show the taxonomic placement of the new species are provided.
... An epitype of R. nitidula was designated by Liu et al. (2014). Roussoella accommodates species having large ascomata with multi-loculate, bitunicate asci and brown, fusiform to ellipsoidal, ornamented, didymospores (Tanaka et al. 2009, Hyde et al. 2013, Liu et al. 2014, Dai et al. 2017, Jiang et al. 2019a, Dong et al. 2020.

... Bamboo fungi are a highly diverse group of organisms [1][2][3][4][5], and research on bambusicolous fungi also provides opportunities to control bamboo diseases and promote bamboo cultivation [6]. Approximately 150 basidiomycetes and 1150 ascomycetes have been reported from bamboo, including 350 asexual morphs, 240 hyphomycetes, and 110 coelomycetes [4,6]. ...
Asexual and sexual morphs of saprobic bambusicolous fungi were collected from freshwater and terrestrial habitats in Sichuan Province, China. Taxonomic identification of these fungi was carried out on the basis of morphological comparison, culture characteristics, and molecular phylogeny. Multi-gene phylogeny based on combined SSU, ITS, LSU, rpb2, and tef1α sequence data was performed to determine their phylogenetic placement, and the result showed that these fungi belong to Savoryellaceae. Morphologically, four asexual morphs are similar to Canalisporium and Dematiosporium, while a sexual morph well-fits to Savoryella. Three new species, Canalisporium sichuanense, Dematiosporium bambusicola, and Savoryella bambusicola are identified and described. Two new records, C. dehongense and D. aquaticum, were recovered from the bamboo hosts in terrestrial and freshwater habitats, respectively. In addition, the nomenclatural confusion of C. dehongense and C. thailandense is discussed.
... Therefore, freshwater Dothideomycetes are distributed all over the world where suitable freshwater environments occur for fungal growth. Freshwater dothideomycetous species have been extensively studied in some countries ranging from temperate to tropical regions, such as Australia (Hyde 1995, Hyde & Wong 1999, Japan (Tanaka et al. 2009(Tanaka et al. , 2015, China (Hong Kong, Guangxi, Guizhou, Yunnan) (Tsui et al. 1999, Ho et al. 2000, Su et al. 2016, Lu et al. 2018b, Thailand (Luo et al. 2016c, Zhang et al. 2016) and USA (Raja et al. 2010. Dong et al. (2020b) concluded that freshwater Dothideomycetes are distributed in 35 countries, with China having the most species, followed by Thailand. ...
Research into freshwater fungi has generated a wealth of information over the past decades with various published articles, i.e., reviews, books, and monographs. With the advancement of
methodologies used in freshwater fungal research, and numerous mycologists working on this ecological group, our knowledge progress and understanding of freshwater fungi, including novel
discoveries and new insights in the ecology of freshwater fungi, has advanced. With this enormous progress, it is timely that an updated account of freshwater fungi be compiled in one volume. Thus, this account is published to give a comprehensive overview of the different facets of freshwater fungal biology. It includes an updated classification scheme based on the latest taxonomic and phylogenetic analysis of freshwater fungal taxa, including their evolutionary history. The biology, diversity, and geographical distribution of higher and basal freshwater fungi are also discussed in the entries. A section on dispersal and adaptation of filamentous freshwater fungi is included in the present work. The ecological importance and role of fungi in the breakdown of wood in freshwater habitats, including their physiology, are discussed in detail. The biotechnological potential of freshwater fungi as producers of bioactive metabolites are reviewed, with methodologies in antimicrobial drug discovery. The present volume also provides an overview of different high throughput sequencing (HTS) platforms for freshwater fungal research highlighting their advantages and challenges, including recent studies of HTS in identification and quantification of fungal communities in freshwater habitats. The present volume also identifies the knowledge gaps and direction of future research in freshwater fungi.
... The Tetraploa and Glomus indicate rich plant diversity and availability of water in the region. These fungi are commonly found as mycorrhizal fungi on roots, leaves and stems of Poaceae and Cyperaceae (Tanaka et al. 2009). Glomus is mostly found during the early phase of late Holocene, often used as an indicator of soil erosion, and dry climatic conditions, since this fungus primarily lives underground (Anderson et al. 1984;van Geel et al. 2003). ...
A total 31 sediment samples from a 150 cm deep sedimentary core was examined for the Non-Pollen Palynomorphs (NPPs) analysis from the Sakali wetland in order to provide an overview of palaeoenvironment in Majuli Island (world largest river island), Assam for the late Holocene. About 25 varieties of non-pollen palynomorphs were reported, out of which fungal spores were at high abundance along with scanty occurrence of zoological remains reflecting the past climate vegetation and faunal interactions in the region. The dominance of coprophilous fungi like Sordaria, Podospora, Ascodesmis, Coniochaeta (almost 40%) indicates the past occurrence of vast open-land areas with grazing activities of herbivorous animals. Some non-coprophilous fungi like Tetraploa, Dictyosporium, Cookeina indicates the rich floral diversity around the study site. Other fungal remains like Valsaria, Alternaria, Geastrum and Diploidia along with the presence of zoological remains like Neorhabdocoela are indicative of the freshwater ecosystem with diversified rich flora indicating warm and humid climate conditions in the region. The presence of Entophlyctis lobata at the bottom of the sedimentary core indicates the relatively dry climatic conditions in the island because this fungal spore is specific of the temperate region. The frequent soil erosional activities could be evident through the dominance of branched and solitary Glomus, attributable to the high flood-prone region resulting in the mixing of local vegetation with the outlandish vegetation. The scanty occurrence of Botryococcus, supports the high energy levels in wetland water, attributed to frequent flood activities. All these NPP varieties of fungal, algal and zoological affinities collectively display the past forest cover, palaeo-depositional environment, past climatic conditions, anthropogenic response and grazing activities in Majuli Island of Assam.KeywordsLate-HoloceneNon-pollen palynomorphsPalaeoenvironmentEcology, fungal sporesMajuli IslandAssam
