“…Besides Exidiopsis as indicated in diagnosis, this new genus is also close to Crystallodon and Heteroradulum in morphology. However, Crystallodon differs in the presence of hyphal pegs surrounded by crystals (Alvarenga and Gibertoni, 2021), while Heteroradulum has brightly colored (pinkish or reddish) basidiomes and a mono-or dimitic hyphal system with thick-walled generative hyphae (Malysheva and Spirin, 2017;Li et al, 2022b). The main taxonomic morphological differences among Alloexidiopsis and related corticioid genera in Auriculariales are summarized in Table 2 Description: Basidiomes annual, resupinate, membranaceous, becoming leathery upon drying, closely adnate, widely effused, up to 12 cm long, 2 cm wide, 100-200 µm thick.…”

“…The type genus of this order is Auricularia , which together with several other gelatinous genera, namely, Exidia, Guepinia , and Pseudohydnum , comprise important edible and medicinal fungi (Wu et al, 2019 ). Therefore, interest in species diversity in these gelatinous genera has grown significantly in recent years (Bandara et al, 2015 ; Chen et al, 2020 ; Shen and Fan, 2020 ; Ye et al, 2020 ; Wang and Thorn, 2021 ; Wu et al, 2021 ).…”

“…With the aid of molecular phylogeny, the corticioid species traditionally placed in Eichleriella, Exidiopsis, and Heterochaete according to morphological characters have been rearranged to make genera monophyletic. After the erection of some new genera, e.g., Adustochaete, Amphistereum, Crystallodon, Proterochaete, and Sclerotrema and reinstatement of several previously known genera, e.g., Hirneolina, Heteroradulum, and Tremellochaete (Malysheva and Spirin, 2017), Eichleriella is accepted to be a monophyletic genus, while Exidiopsis and Heterochaete seem to be synonymous with a priority of the latter genus (Malysheva and Spirin, 2017;Alvarenga et al, 2019;Alvarenga and Gibertoni, 2021). However, certain species of Exidiopsis, even sequenced ones such as E. calcea and E. grisea, still have no appropriate placement at the generic level (Malysheva and Spirin, 2017;Li et al, 2022b).…”

Auriculariales is a fungal order with highly diverse morphological traits of basidiomes, which partially leads to a poor understanding of its taxonomic system at the generic level. To identify our recently collected specimens of Auriculariales to a species level, we perform a comprehensive phylogenetic analysis of the generic relationships in Auriculariales. In association with morphological characteristics, a new genus Alloexidiopsis belonging to Auriculariaceae is erected with two new species, namely, A. australiensis and A. schistacea. Moreover, Exidiopsis calcea separated from the generic type E. effusa and Heteroradulum niveum and H. yunnanense recently inaccurately described as members of Heteroradulum are recovered in the clade of Alloexidiopsis. These three species are thus transferred to this new genus. One collection of Exidiopsis grisea also falls in the clade of Alloexidiopsis, whereas another collection of this species is separated far from Alloexidiopsis and E. effusa. Since we have no collection to confirm the species identity of E. grisea, its generic position is uncertain. The main taxonomic morphological differences among Alloexidiopsis and related corticioid genera in Auriculariales are summarized. A key to all the five accepted species of Alloexidiopsis is provided. As two unnamed lineages exist in Alloexidiopsis besides the abovementioned five species, it is assumed that more new species will be revealed from this genus under its current circumscription.

“…Wood-rotting fungi are an extensively studied group of Basidiomycota [ 12 , 13 , 60 , 61 , 62 , 63 , 64 , 65 , 66 ] and the three taxa of Trechispora are a typical example group of wood-rotting fungi [ 15 , 33 , 34 , 35 , 67 ]. Based on our present morphology and phylogeny focusing on Trechispora , all taxa in this genus can be separated from the three new species.…”

Trechispora are an important genus of wood-inhabiting fungi that have the ability to decompose rotten wood in the forest ecosystem. In this study, we reported three new species of Trechispora: T. murina, T. odontioidea, T. olivacea from a subtropical region of Yunnan Province, China. Species descriptions were based on a combination of morphological features and phylogenetic analyses of the ITS and LSU region of nuclear ribosomal DNA. Trechispora murina is characterized by the resupinate basidiomata, grandinioid hymenial surface with a greyish tint, monomitic hyphal system and ellipsoid, thick-walled, ornamented basidiospores; T. odontioidea has an odontioid hymenial surface with cylindrical to conical, blunt aculei and subglobose to globose, colorless, slightly thick-walled, ornamented basidiospores; T. olivacea has a farinaceous hymenial surface with olivaceous tint, basidia clavate and thick-walled, ornamented, broadly ellipsoid to globose basidiospores. Sequences of the ITS and nLSU rDNA markers of the studied samples were generated, and phylogenetic analyses were performed with maximum likelihood, maximum parsimony, and Bayesian inference methods. After a series of phylogenetic analyses, the 5.8S+nLSU dataset was constructed to test the phylogenetic relationship of Trechispora with other genera of Hydnodontaceae. The ITS dataset was used to evaluate the phylogenetic relationship of the three new species with other species of Trechispora. Using ITS phylogeny, the new species T. murina was retrieved as a sister to T. bambusicola with moderate supports; T. odontioidea formed a single lineage and then grouped with T. fimbriata and T. nivea; while T. olivacea formed a monophyletic lineage with T. farinacea, T. hondurensis, and T. mollis.

Auricularia heimuer (A. heimuer F. Wu, B. K. Cui, Y. C. Dai), a well-known gelatinous fungus used for both food and medicine, is a major edible fungus with a more than 1000-year history of cultivation in China. The nutrients of A. heimuer are abundant, including polysaccharides, melanin, mineral elements, etc. The A. heimuer polysaccharides exhibit antioxidant, immunomodulatory, and anticancer properties. A. heimuer is a completely different species grown in China, unlike Auricularia auricula-judae (Bull.) Quel, which was used to characterize it. The cultivated strain varies based on the local climatic factors and cultivation practices. Hardwood chips are the primary material utilized in the cultivation of substitute materials, which is the principal cultivation technique. However, in actual production, straw is frequently replaced for some wood chips to address the issue of a lack of wood. There are three different types of growing techniques: open-air ground cultivation, arch cultivation, and shed-type hanging substitute cultivation of these three, the quality of A. heimuer grown in a shed is superior to that grown in an open-air environment. The A. heimuer genome sequencing project started later than expected, and the entire genome sequencing was not finished until 2019. A. heimuer’s molecular biology studies have mostly concentrated on analyzing genetic diversity and identifying cultivars using molecular markers including RAPD, ISSR, and ITS. There have only been a small number of studies on the function of A. heimuer genes, which have only focused on the preliminary cloning and expression study of a few genes, including the laccase gene and the triterpene compound production gene, among others. However, there is still a lack of comprehensive information concerning A. heimuer, necessitating a synopsis. To our knowledge, this is the first published review of A. heimuer, and it summarizes the most recent studies on its molecular biology and cultivation. This review can serve as a guide for future research on the fungus.
