<p class="Myc1title"><strong><em>Russula fanjing</em>, a new species of <em>Russula</em> subsect. <em>Russula</em> (Russulaceae, Russulales) from Guizhou province, China</strong></p>

Abstract

Russula fanjing is proposed here as a new species based on morphological and molecular evidence. The new species is described and illustrated with photographs and line drawings and compared to related species. Morphologically, R. fanjing (subgenus Russula, section Russula, subsection Russula) is characterized by a medium-sized basidioma, with a vivid red to pastel red areolate pileus, white lamellae occasionally forked near the stipe with lamellulae, a smooth white stipe, basidiospores ornamented with strongly amyloid warts and ridges interconnected by fine lines in an incomplete or complete reticulum, and a pileipellis a typical trichoderm with suprapellis cells composed of short-celled, claw-like branched, lotus-root-like inflated hyphae and dispersed clavate, septate pileocystidia. The phylogenetic analysis of the nucleotide sequences of the internal transcribed spacer (ITS) region provided further evidence that the described species belongs to subsection Russula and represents a new taxon.

Two new species of Russula subgenus Heterophyllidia (Russulaceae, Russulales) from Yanshan Mountains, North China

“…In the last 10 years, 59 new species European Journal of Taxonomy 861: 185-202 (2023) of Russula have been described worldwide. Of them, 31 species belong to the subgenus Heterophyllidia (Li et al 2013(Li et al , 2018(Li et al , 2020(Li et al , 2021a(Li et al , 2021bHyde et al 2019;Deng et al 2020;Song et al 2020Song et al , 2021Song et al , 2022Zhou et al 2020;Chen et al 2021aChen et al , 2021bChen et al , 2021cChen et al , 2022.…”

Four new species of Russula from the Xizang Autonomous Region and other provinces of China

“…Since 2006, at least 68 new species have been published for the crown clade of subg. Russula , 48 of which are from Asia, and 23 new species have been described for this clade from China, demonstrating the extraordinary species richness of this clade of the Russula crown clade (Li et al 2012 , 2013a , 2013b , 2015 , 2016 ; Jiang et al 2018 ; Li et al 2018a , 2018b , 2021 ; Caboň et al 2019 ; Song et al 2021 ; Li 2022 ; Zhou et al 2022 ). Members of Russula crown clade mostly have unchanging, yellowing, browning, reddening, greying, or blackening of context when bruised, sometimes with distinct disagreeable to agreeable smell, mild to strongly acrid tasted context, white to yellow spore print (Buyck et al 2018 ).…”
