Abstract
Russula is one of the more easy genera of Hymeno-mycetes to recognise, but one of the more difficult to classify into species. The spores of Russula are ornamented with minute tubercles or warts, sometimes joined together by lines, and the disposition of this ornamentation is used by Mr. Crawshay as an accessory character in the specific classification of the genus. The spores themselves, however, are only a few micromillimetres in length, and the differences in the surface markings are so slight that it would, in many cases, need an experience as intensive as that of the author himself to distinguish them.
