Abstract

The first eight figures accompanying this article show the spore ornamentation of Russulae described by the late C. H. Kauffman.1 As usual the drawings were made with the aid of a camera lucida, using an oil immersion lens and treating the spores with an iodine stain. The magnification is about 1500 times. The spores examined were taken from type specimens. The following species of Lactaria has been found in Florida for several seasons, occurring in abundance through November, and December 1940 and January 1941.
