Russula farinipes Taxonomy and Etymology
The currently-accepted scientific name of the attractive brittlegill dates from an 1893 publication by the Swedish mycologist Lars Romell (1854 - 1927).
Russula, the generic name, means red or reddish, and indeed many of the brittlegills do have red or somewhat reddish caps.
The specific epithet farinipes refers to the surface of the stem, the upper section of which has a farinaceous texture, meaning that it is covered in a flour-like powder.
