“…Furthermore, a preliminary taxonomic study on Calocybe was performed in recent years ( Zhou 2022 ). And recently, more than ten new species have been described in northeast China ( Li et al 2017 ; Xu et al 2021a , 2021b ; Qi et al 2022 ; Mu and Bau 2023 ), and proposed their perspective on the taxonomic systematic on Calocybe . As a result, a total of 19 species of Calocybe have been reported, including Calocybe aurantiaca X.D.…”

The Calocybe species possess notable economic and medicinal value, demonstrating substantial potential for resource utilization. The taxonomic studies of Calocybe are lacking in quality and depth. Based on the specimens collected from northeast China, this study provides a detailed description of two newly discovered species, namely Calocybe betulicola and Calocybe cystidiosa, as well as two commonly found species, Calocybe decolorata and Calocybe ionides. Additionally, a previously unrecorded species, C. decolorata, has recently been discovered in Jilin Province, China. The two newly discovered species can be accurately distinguished from other species within the genus Calocybe based on their distinct morphological characteristics. The primary distinguishing features of C. betulicola include its grayish-purple pileus, grayish-brown to dark purple stipe, smaller basidiomata, absence of cellular pileipellis, and its habitat on leaf litter within birch forests. Calocybe cystidiosa is distinguished by its growth on the leaf litter of coniferous forests, a flesh-pink pileus, a fibrous stipe with a white tomentose covering at the base, non-cellular pileipellis, larger basidiospores, and the presence of cheilocystidia. The reconstruction of phylogenetic trees using combined ITS, nLSU, and tef1-α sequences, employing maximum likelihood and Bayesian inference analyses, showed that C. betulicola formed a cluster with C. decurrens, while C. cystidiosa clustered with C. vinacea. However, these two clusters formed separate branches themselves, which also supported the results obtained from our morphological studies. A key to the Calocybe species reported from northeast China is provided to facilitate future studies of the genus.

The diversity of macrofungi has been closely associated with forest diversity and stability. However, such a correlation has not been established for the forests of the Ningxia Autonomous Region due to the lack of systematic data on its macrofungal diversity. Therefore, for the present study, we collected 3130 macrofungal specimens from the forests of the Helan Mts., Luo Mts., and Liupan Mts. in Ningxia and assessed them using morphological and molecular approaches. We identified 468 species belonging to 157 genera, 72 families, 18 orders, 11 classes, and 2 phyla. Among them, 31 species were ascomycetes, and 437 species were basidiomycetes. Tricholomataceae, with 96 species of 22 genera, was the most species-rich family, and Inocybe was the most species-rich genus (6.2%). The Jaccard similarity index measurement revealed the highest similarity in macrofungal species (16.15%) between the Helan and Liupan Mountains and the lowest (7.72%) between the Luo and Liupan Mountains. Further analyses of the macrofungal population of Ningxia showed that 206 species possess considerable potential for utilization, including 172 edible, 70 medicinal, and 36 edible–medicinal ones. Meanwhile, 54 species were identified as being poisonous. In these forests, saprophytic fungi were the most abundant, with 318 species (67.95%), followed by symbiotic fungi (31.62%) and parasitic fungi (0.04%). Grouping based on the geographical distribution indicated that the fungi of Ningxia are composed mainly of the cosmopolitan and north temperate types. These observations unveil the diversity and community structure of macrofungi in Ningxia forests.
