Ganoderma is a typical polypore genus which has been used in traditional medicines for centuries and is increasingly being used in pharmaceutical industries worldwide. The genus has been extensively researched due to its beneficial medicinal properties and chemical constituents. However, the taxonomy of Ganoderma remains unclear, and has been plagued by confusion and misinterpretations. During an extensive survey of Ganoderma we were found 20 G. sinense specimens from China. The specimens were identified as G. sinense with the aid of molecular phylogenetic evidence. The studied specimens exhibit phenotypic plasticity due to extrinsic factors, even though they possess identical nucleotide sequences. Seven sequences derived from this study have a single nucleotide polymorphism located at position 158 in ITS1 region and all G. sinense collections clustered in the same species clade. The specimens are each described, illustrated with coloured photographs and compared to similar taxa. We provide a phylogenetic tree for Ganoderma based on ITS, SSU, LSU and RPB2 sequence data and the taxonomic status of G. sinense is discussed.

In the present study, lichenized discomycete taxa collected from northern Thailand, southern China, the UK, Ukraine and Russia are documented. Taxonomic studies of these taxa were carried out using both morphology and molecular data. Their phylogenetic relationships were inferred using LSU rDNA and ITS rDNA sequence data or combined analysis of these gene regions. Twelve lichenized discomycete taxa are reported in this paper including three new species (viz. Bacidia subareolata, Buellia sublauri-cassiae and Letrouitia magenta) and one reference species (Letrouitia transgressa).

Recieved: 25 February 2019, Accepted: 05 April 2019, Published: 25 April 2019

Taxonomic studies of leaf litter inhabiting fungi resulted in two saprobic members of Dothideomycetes being collected from Fanlu Township area, Dahu forest, Chiayi in Taiwan (Elevation 630 m). Morphology coupled with combined gene analysis of a LSU, ITS and RPB2 DNA sequence data, showed that they belong to the family Didymellaceae. A new species, Leptosphaerulina longiflori from dead leaves of Lilium longiflorum and a new host record of Didymella sinensis from dead leaves of Roystonea regia are herein described. Leptosphaerulina longiflori is distinguished from other Leptosphaerulina species based on distinct size differences in ascomata, asci, ascospores and DNA sequence data. Both species are compared with other similar species and comprehensive descriptions and micrographs are provided.

Recieved: 14 January 2019, Accepted: 11 April 2019, Published: 25 April 2019

An infection of leaves of Encephalartos barteri (Zamiaceae) by a cercosporoid fungus was repeatedly observed in central Benin, West Africa. Morphological characteristics, the host relationship and DNA sequence data for two gene regions, namely ITS and rpb2, were compared to the corresponding characteristics of closely related, known cercosporoid species and showed that the specimens from Benin represent a new species of Pseudocercospora. Pseudocercospora encephalarti is the first Pseudocercospora species on a species of the host genus Encephalartos, as well as for the whole class Cycadopsida. It was found to be closely associated with a species of Corynespora that could not be identified in the context of the present study.

Edible and medicinal mushrooms are extensively cultivated and commercially consumed in many countries, especially in China and Thailand. A number of fungicolous fungi could cause deformation or decomposition of mushrooms. Investigation of taxonomic diversity and exact identification are initial and crucial steps to understand interactions between fungicolous taxa and their hosts as well as to propose better disease management strategies in the mushroom industry. In this study, during a survey of fungicolous fungi on eight edible and medicinal mushrooms from mushroom farms and from the wild in China and Thailand, 15 taxa were identified based on morphological characteristics and DNA sequence data analyses. Three new species, including Sporothrix ganoderma (Ophiostomatales) on cultivated Ganoderma lucidum in China; Hypomyces fistulina (Hypocreaceae) on Fistulina species in China; and Hypomyces boletus on Boletus species in Thailand are described and introduced here. Other species recovered from China include Aspergillus pseudoglaucus (Trichocomaceae) on a wild Helvella species; Fusarium sonali (Nectriaceae) on cultivated Morchella importuna; Clonostachys rosea f. catenulata (Bionectriaceae) and Paecilomyces hepiali (Cordycipitaceae) on cultivated Ophiocordyceps sinensis; Polycephalomyces sinensis (Ophiocordycipitaceae) on wild Ophiocordyceps sinensis; Lecanicillium fungicola var. aleophilum (Cordycipitaceae) and Hypomyces rosellus on cultivated Agaricus bisporus; Paecilomyces formosus (Trichocomaceae) on Fistulina; Hypomyces aurantius (Hypocreaceae) on Panellus species; Trichoderma atrobrunneum (Hypocreaceae) on cultivated Ganoderma lucidum. Hypomyces boletiphagus (Hypocreaceae) on Boletus sp. and Cladobotryum protrusum (Hypocreaceae) were recovered on a decayed mushroom from Thailand. This study enriches our current taxonomic knowledge on the diversity of fungicolous fungi in these regions.

Phaeosphaeriaceae comprises many fungal species occuring mainly on grasses and cereal crops as endophytes, saprobes and especially pathogens. Parastagonospora is an important genus in Phaeosphaeriaceae that includes pathogens causing leaf and glume blotch on cereal crops. In this study, a sexual morph species and an asexual morph species, occuring as saprobes on Poaceae are introduced based on morphology and a combined molecular analysis of the LSU, ITS and RPB2 gene sequence data. The sexual morph of a new Parastagonospora species, P. elymi was isolated from dead stems of Elymus repens in Russia. Parastagonospora elymi is similar to the sexual morph of P. avenae in having cylindrical asci, bearing eight, overlapping biseriate, fusiform ascospores but can be distinguished by its subglobose to conical-shaped, wider ascomata. In addition, no sheath was observed surrounding the ascospores. An asexual morph of Parastagonospora was isolated from dead stems of Dactylis glomerata in Italy and is introduced as P. macrouniseptata. Parastagonospora macrouniseptata is a coelomycete and bears a close resemblance to P. allouniseptata and P. uniseptata in having globose to subglobose, pycnidia and hyaline, cylindrical, 1-septate conidia. However, the new species is morphologically distinct in its conidiomata characteristics and phylogenetic affinity.

There has been increasing research interest in the isolation of fungal endophytes from different hosts or tissue types of the same host from many tropical regions. However, there have been few studies conducted on musaceous endophytes in Thailand. In this study, we provide the first report of Daldinia eschscholtzii (Hypoxylaceae) as an endophyte isolated from symptomless fresh leaves of Musa sp. (Musaceae) in northern Thailand. In addition, this is the first record of Daldinia from Musaceae and the second report of D. eschscholtzii from monocotyledons. Fungi isolates are illustrated, described and subjected to LSU-ITS-RPB2-BTUB concatenated phylogenies using maximum likelihood and Bayesian analysis with an updated tree of Hypoxylaceae.

10. Phylogenetic and morphological appraisal of Diatrype lijiangensis sp. nov. (Diatrypaceae, Xylariales) from China

Authors: Thiyagaraja V, Senanayake IC, Wanasinghe DN, Karunarathna SC, Worthy FR, To-Anun C

Recieved: 29 April 2019, Accepted: 25 June 2019, Published: 28 June 2019

The majority of Diatrype species are saprobes, while a few species are pathogens which form cankers on forest trees. The placement of several species in the genus Diatrype is uncertain, as the phylogeny has yet to be well-resolved with extensive taxon sampling and authentic ex-type cultures. In this study, a diatrype-like taxon was found on decaying wood in Lijiang, Yunnan Province, China. Morphological characteristics and phylogenetic analyses of combined ITS and β-tubulin sequences, supported the conclusion that the taxon is a new species, which is named as Diatrype lijiangensis. The new species differs from other species of Diatrype in asci and ascospore characteristics. The morphological similarities and dissimilarities of the new species with phylogenetically close alliances are discussed. Micro-morphological characteristics of this novel taxon are illustrated with descriptions.

12. Morphology and phylogeny of Yunnanomyces phoenicis sp. nov. (Sympoventuriaceae) from Thailand

Authors: Zhang SN, Liu JK, Jones EBG, Cheewangkoon R

Recieved: 02 July 2019, Accepted: 15 August 2019, Published: 29 August 2019

A new hyphomycetous species, associated with monocotyledonous Phoenix paludosa (mangrove date palm) was isolated and is introduced in this study. Multi-gene (LSU, SSU and RPB2) phylogenetic analyses showed that the new taxon clustered together with Yunnanomyces pandanicola and formed a well-supported clade within the family Sympoventuriaceae (Venturiales). The taxon is characterized by it semi-macronematous conidiophores, reduced to conidiogenous cells, and bears globose to broadly ellipsoidal, muriform conidia. It is morphologically similar to Yunnanomyces pandanicola, but differs from the latter in its reduced conidiophores and larger, brown conidia. The phylogenetic result also confirms that this fungus is a distinct species of Yunnanomyces. Therefore, Yunnanomyces phoenicis sp. nov. is introduced herein, and its morphological features, sporulation in culture are described and illustrated, as well as its phylogenetic placement is provided.

Authors: Samarakoon MC, Wanasinghe DN, Liu JK, Hyde KD, Promputtha I

Recieved: 23 September 2019, Accepted: 31 October 2019, Published: 31 October 2019

Neoaquastroma is a saprobe on dead twigs, characterized by having immersed, globose to sub-globose ascomata, short papillate ostiole, a thin peridium with cells of textura angularis, branched, septate pseudoparaphyses, cylindrical clavate, short pedicellate asci with an ocular chamber, overlapping biseriate to triseriate, ellipsoidal to sub-fusiform, hyaline, multi-septate ascospores with a distinct mucilaginous sheath. They have a coelomycetous asexual morph with uniloculate, pycnidial conidiomata, enteroblastic, phialidic, integrated, hyaline, oblong conidiogenous cells, broad-oblong to oval, hyaline, aseptate conidia. Earlier they were only reported from Thailand. In this study, we found another new species to the genus (Neoaquastroma cylindricum) from Guizhou, China as the fourth species based on both morpho-phylo evidences. Neoaquastroma cylindricum is distinguished from other Neoaquastroma species by its cylindric-clavate asci and comparatively small ascospores with a smaller number of transverse septa. Maximum parsimony, maximum likelihood and Bayesian inference analyses of combined LSU–SSU–ITS–tef1 sequence matrix confirmed its placement within Parabambusicolaceae with a close affinity to Neoaquastroma krabiense. The new taxon is compared with other species in Neoaquastroma and comprehensive descriptions, illustrations (including DNA based phylogenies) and a synopsis table for relevant species are provided.

Arthrinium setostromum sp. nov., collected from dead branches of bamboo in Yunnan Province of China, is described and illustrated with the sexual and asexual connections. The sexual morph of the new taxon is characterized by raised, dark brown to black, setose, lenticular, 1–3-loculate ascostromata, immersed in a clypeus, unitunicate, 8-spored, broadly clavate to cylindric-clavate asci and hyaline apiospores, surrounded by an indistinct mucilaginous sheath. The asexual morph develops holoblastic, monoblastic conidiogenesis with globose to subglobose, dark brown, 0–1-septate conidia. Arthrinium setostromum can be distinguished from other phylogenetically closely related species by its setose ascostroma, with setae raising through a split of the clypeus. Maximum likelihood, maximum parsimony and bayesian inference analyses based on a catenated ITS, LSU, TEF1-α and TUB2 DNA sequence dataset demonstrate that A. setostromum is a distinct new species phylogenetically closely related to A. garethjonesii, and clusters with A. bambusae, A. mytilomorphum and A. subroseum.

In our investigation of epifoliar fungi, a novel species of Ceramothyrium; C. chiangraiense is isolated from the living leaves of Ficus sp. in Thailand. Genus Ceramothyrium is characterized by the ascomata covered with pellicle mycelium and the circumferential space around the maturing ascomata, bitunicate asci and phragmospores which lack setae. The new species resembles genus Ceramothyrium by its ascomata with superficial mycelial pellicle over the fruiting structures and scattered ascomata that cupulate when dry and 8-spored, bitunicate asci which contain hyaline, pluriseptate ascospores. We have processed the phylogeny based on Maximum Likelihood (ML) and Bayesian (BI) analyses using combined ITS and LSU sequence data. Based on phylogeny, C. chiangraiense is confirmed its placement within the genus Ceramothyrium and closely related to C. aquaticum, C. carniolicum, C. exiguum, C. linnaeae and C. phuquocense. Morphologically, C. chiangraiense is distinguished from phylogenetically related species (Ceramothyrium carniolicum, C. ficus, C. linnaeae, C. longivolcaniforme, C. menglunense, C. paiveae and C. thailandicum) by having obpyriform asci and 3–4 seriate, oblong to ellipsoid ascospores with 4–7 longitudinal and angled septa. An updated phylogenetic tree for the family Chaetothyriaceae (Eurotiomycetes) is constructed. The relationships of C. chiangraiense to other Ceramothyrium species are discussed based on comparative morphology and phylogenetic analyses.

Correct taxonomic identification of phytopathogens is essential as there is a need to gather precise stored information on different genera. It is important to scientifically document and records the diversity of fungal pathogens in order to collate information, as well as for utilizing the data efficiently. Fungal databases need to play an essential role in the documentation of fungal pathogens. There are numerous fungal databases which provide lists of fungal names, literature, DNA sequence and morphological data to facilitate morpho-molecular identification, however, few are dedicated to the identification of phytopathogens. For this reason, a web-based platform is established, namely https://www.onestopshopfungi.org to fill the void, as well to enhance the identification of phytopathogenic genera based on the One Stop Shop publication series. This paper introduces the database, explains its function, provides data on the information it includes and how to use it and invites plant pathologists to participate in building the database.
