Perfect specimen of this attractive mushroom intact and in its full Identification guideĪlthough they are so often damaged by slugs, occasionally you come across a The old common name Blackish-purple Russula might as well have been superceded by Blackish-purple Brittlegill, but I guess that three-word common name was considered to be a hyphen too far.
The specific epithet atropurpurea is made up of the prefix atro-, which means black (or blackish), and purpurea, which of course means purple. Russula, the generic name, means red or reddish, and indeed many of the brittlegills have red caps (but many more are not, and some of those that are usually red can also occur in other colours!). krombholzii Singer, and Russula krombholzii Shaffer. atropurpurea ( Krombh.) Melzer & Zvára, Russula atropurpurea var. Synonyms of Russula atropurpurea include Agaricus atropurpureus Krombh., Russula undulata Velen., Russula depallens var. (Most gilled mushrooms were initially included initially in the genus Agaricus, whose contents have since been largely spread across several newer genera.) In 1893 this species was transferred to the Russula genus by another German mycologist, Max Britzelmayr (1839 – 1909). This brittlegill was described in 1845 by German mycologist Julius Vincenz von Krombholz (1782 - 1843), who called it Agaricus atropurpureus. DistributionĪ common find in woodlands throughout Britain and Ireland, the Purple Brittlegill occurs in most countries of mainland Europe and in other parts of the world including Asia and North America. The mature fruitbodies shown on the left have developed concave caps that collect water during wet weather, and much of the colour has washed off from areas of the cap near to the rim. When old, the fruitbodies often fade, especially towards the cap rims, but the centres remain blackish. This mushroom is one of the most common brittlegills in Britain and Ireland.
