本文记述了产于热带地区中国的一新种--灰果红菇(Russula Grisecarnosa)，该种曾长期误名为欧洲红曲霉(R.vinosa)，被广泛用于食药两用。深红色的粘性菌盖，最初的灰色背景，白色的孢子印记，近球形到椭圆形的担孢子，具有高和急性的疣，以及没有皮孢子虫的菌盖，使这一新分类群具有明确的定义。它在上下文和菌毛结构的灰色色调上类似于R.vinosa，但在白色孢子印记上与后者不同，担孢子上的刺明显更高，生长在与壳斗科一起的森林中，而不是在针叶林中。基于ITS-nLSU-rDNA序列数据的分子分析表明，灰果核菌与棕色核盘菌聚在一起，但明显不同于后者。其外生菌根形态进一步支持了系统发育的位置。
A new species, Russula griseocarnosa, which was popularly commercially collected as food and medicine and misnamed as European R. vinosa for a long time, is described from tropical China. The dark red sticky pileus, initially greyish context, white spore print, subglobose to ellipsoid basidiospores with high and acute warts, and the pileipellis without dermatocystidia make this new taxon well defined. It resembles R. vinosa in the greyish tinge of the context and the pileipellis structure, but differs from the latter in its white spore print, significantly higher spines on basidiospores, and growing in forests with Fagaceae rather than in coniferous forests. The molecular analysis, based on a combined ITS - nLSU-rDNA sequence data get, showed that R. griseocarnosa clustered with R. vinosa but is clearly distinct from the latter. The phylogenetic placement is further supported by its ectomycorrhizal morphology.
