“…One could argue that this might be the result from limited sampling, but even recent studies with extensive sampling within individual subgenera appear to suggest a similar scenario. Example given, Xie et al (2023) described the tropical Asian R. lacteocarpa as basal to all known species in subgen. Archaeae, one of the more ancient lineages in the genus.…”

The application of DNA data on a worldwide sampling has revolutionized the infrageneric classification of the highly diverse ectomycorrhizal genus Russula. Based on collections made in New Zealand, East Asia and North America, this study describes the new subgenus Cremeoochraceae, the ninth subgenus in Russula. Even though BLASTn of the ITS sequences suggested affinities with species of subgenera Russula and Heterophyllidiae, the phylogenetic analysis based on a five-locus DNA dataset placed the target samples in an independent major clade that is systematically equivalent to subgenus. The new subgenus shares with subgen. Brevipedum subsect. Pallidosporinae the general field habit, the unequal lamellae and the relatively small spores with inamyloid suprahilar spot and similar spore ornamentation. It differs from the latter subsection principally in the poor contents of all types of cystidioid cells and the often areolate-scurfy pileus surface composed of slender, undulating hyphal terminations with frequent subcapitate apices. Biogeographically, subgen. Cremeoochraceae shares with Multifurca, the sister genus of Lactarius, a circum-Pacific distribution pattern with the exception of South America. Both lineages lack representatives in Europe and Africa. The hypothesis proposing an African origin for the genus is considered unlikely.

Huotanjun (Burnt Charcoal Mushroom) is a group of edible mushrooms widely hunted and eaten in southern China.Taxonomically they belong to Russula sect. Nigricantinae. Confusion with the fatal R. subnigricans cause many poisoning incidents in Asia. For a long time, European names were used in Asia but the Asian genotypes are not the same as European species. We studied specimens collected from markets and the eld in southern China. Analysis of four DNA loci (ITS, nc LSU, TEF1-α, RPB2) showed that except for a specimen of R. adusta from subalpine Abies forest in southwestern China, all the specimens represent species different from European and North American ones, suggesting prevalent continental endemism in this group. Four new species were described. Among them R. sinoadusta and R. zhuzuijun are Asian counterparts of R. adusta; R. brunneocystidia and R. huotanjun are closely related with European R. densifolia and R. fuliginosa. These species are highly similar to their European siblings and the morphological differences are very subtle. Using multi-locus data, for the rst time, we determined the phylogenetic position of R. subnigricans. It was nested in R. sect. Nigricantinae and sister to R. latolamellata, a species also having distant lamellae and only reddening context. Geographically except for R. sinoadusta known only from China, all species are shared by China and Japan. We analyzed presence/absence of the diagnostic toxin of R. subnigricans cycloprop-2-ene carboxylic acid for 12 species and did not detect the polymeric products in any of them but R. subnigricans. Nevertheless, considering several potentially edible species also have spaced lamellae and only reddening discolouration which can be easily confused with R. subnigricans, we strongly recommend to only eat species with decidedly blackening context and gills.
