A new species ofRussula , subgenusCompactaefrom California

[摘要] A new species ofRussula , subgenusCompactae , is described growing in association with coast live oak ( Quercus agrifolia ) in California.  This species has previously been referred to locally asRussula subnigricansHongoand Russula eccentricaPeck, but morphological and DNA evidence show that it is a distinct species which we callR. cantharellicola . Our analysis shows that there are multiple clades of what is calledR. subnigricans , and that the California species clearly falls within one of those clades. AsR. subnigricanshas caused deaths in Japan, China, and Taiwan, the California species should be cautioned as potentially dangerous to those who consume it.
