“…The hyphal cells in subpellis and epipellis of R. prasina are reminiscent of those of R. parvovirescens Buyck, D. Mitch. & Parrent, in contrast, R. parvovirescens has pileocystidia in pileipellis and hymenium with pleurocystidia and cheilocystidia (Buyck et al 2006). This new species may be confused with some green-capped Russula in China and adjacent region, e.g.…”

“…However, R. viridirubrolimbata , originally described from China, can be distinguished by a light yellowish olive to yellowish olive pileus center with a pinkish red to light jasper red margin and absence of hymenial gloeocystidia on lamellae edges ( Ying 1983 ; Deng et al 2020 ). The American species R. parvovirescens possesses a greenish brown to metallic bluish green pileus with green patches ( Buyck et al 2006 ). Russula virescens (originally reported from Europe) is distinct in its green to yellowish green pileus ( Sarnari 1998 ).…”

Two new species of Russula subg. Heterophyllidia from Guangdong Province of China were described and illustrated based on morphological characters, and their identity supported by molecular phylogeny. R. luofuensis is morphologically characterized by a grayish yellow to brownish orange pileus center with a purplish gray to grayish magenta margin, a surface that is cracked and broken into small golden-brown patches, subglobose to broadly ellipsoid basidiospores with warts fused in short or long chains and a suprapellis composed of hyphal extremities with inflated, ellipsoid or globose cells and attenuated terminal cell. R. subbubalina is distinguished by the blanched almond to dark salmon pileus that is cracked with age, subglobose to broadly ellipsoid basidiospores with wart fused in short or long chains and frequently connected by line connections, a suprapellis with hyphal ends composed of inflated or ellipsoid cells and attenuated terminal cell, and pileocystidia that are mainly clavate and sometimes with round or ellipsoid appendage. The phylogenetic analyses based on ITS-nrLSU-mtSSU-TEF1 dataset were performed using maximum likelihood and Bayesian analysis. In terms of morphological features and molecular data, the former species belongs to subsect. Virescentinae, whereas the latter comes under subsect. Heterophyllinae.

Russula is a worldwid genus which has a high species diversity . Aiming accurate and rapid species identification, candidate genes nLSU (28S), ITS, tef-1α, mtSSU, rpb1, and rpb2, were analysed as potential DNA barcodes. This analysis included 433 sequences from 38 well-circumscribed Russula species of eight subgenera. Two vital standards were analysed for success species identification using DNA barcodes, specifically inter-and intra-specific variations together with the success rates of PCR amplification and sequencing. Although the gap between inter-and intra-specific variations was narrow, ITS met the qualification standards for a target DNA barcode. Overlapping inter-and intra-specific pairwise distances were observed in nLSU, tef-1α, mtSSU, and rpb2. The success rates of PCR amplification and sequencing in mtSSU and rpb1 were lower than those of others. Gene combinations were also investigated for resolution of species recognition. ITS-rpb2 was suggested as the likely target DNA barcode for Russula, owing to the two viatal standards above. Since nLSU has the lowest minimum of inter-specific variation, and tef-1α has the highest overlap between intra-and inter-species variations among the candidate genes, they are disqualified from the selection for DNA barcode of Russula.
