This paper is the third of a series intended to present the common fleshy fungi of the state. The purple-brown- and white-spored groups of the gilled mushrooms were previously presented in 1940 and 1941, respectively. The mushrooms that are characterized by black spores comprise the forms described and illustrated in this paper.
