New Contributions on Species Diversity of Genus and s.l. in China.

Southwest China is extremely rich in fungal resources, and a large number of new taxa have been discovered in recent years. In the present study, we examined 26 specimens of the genera and sensu lato, most of which were obtained in Yunnan Province. Through ITS-nrLSU- phylogenetic analysis, combined with morphological studies and geographic analyses, five new species were described, viz.

(, ), a new species from southwestern China.

(, ) is described as a novel species from Yunnan Province, southwestern China. It is morphologically recognised by a small basidiocarp with orange-yellow to orange-red scales on the pileus and stipe, white lamellae, orange-red to bright red basal mycelia, subglobose to broadly ellipsoid basidiospores with dense warts and short or long ridges. Phylogenetically analyses of DNA sequences from part of the 28S gene combined with the nuclear rDNA internal transcribed spacer (ITS) region also confirm that forms an independent lineage within subgenus section .

Four New Species and a New Combination of () from Subtropical and Tropical China.

Previous studies have shown that boletes are abundant and diverse in China, especially in tropical and subtropical regions. In the present study, morphological, ecological, host relationship, and a four-locus (28S, , , and ) molecular phylogenetic analyses were used to study the family in subtropical and tropical China. Four new bluing species are described from three genera, viz.

Four cases of reported adverse effects from black boletoi, Anthracoporus nigropurpureus (Boletaceae) mushroom ingestion.

In southwestern China, wild boletes are generally considered as safe and tasty edible mushrooms. However, in fact, significant adverse effects after ingestion of boletes is commonly reported in this region. In June 2022, four cases occurred in central and southwestern of China.
