This fungus forms more or less extensive patches over the sur- 

 face of the wood. The upper part of the flocci being covered with 

 spores, the general aspect is somewhat similar to that of some 

 species of Ceratium, e. g., C. hydnoides. The spores are so abun- 

 dant that they hide the flocci and at first sight the whole fungus 

 appears to be pale ochraceous. The smooth spores and white flocci 

 separate this species from B. carnea, Schum. 

 Dactylium dendroldes, Fr. 



Decaying wood and fungi. East Berne. August. 



Verticillium agarici?ium, Bon., is closely related if not, indeed, 

 the same species. 

 Verticillium Lactarii, n. sp. 



Flocci branched, white; branches either simple, opposite or 

 verticillate, the ultimate ramuli tapering to the apex; spores 

 apical, obovate or oblong-elliptical, smooth, colorless, -0006' — 



• 0012' long, -0004' — 0005' broad, usually with a slight point or 

 apiculus at the base. 



Putrescent Lactarii, especially L. subdulcis. Center and East 

 Berne. Jun e — August. 

 Cercospora Till^;, Ph. 



Living leaves of basswood, Tilia Americana. Sandlake. July. 

 Cercospora Lepidii, n. sp. 



Spots small, orbicular, grayish-brown or subcinereous, usually 

 marked with faint concentric lines; flocci amphigenous, about 



• 0016' long, single or two to three in a cluster, pallid ; spores very 

 long, tapering upwards, slightly constricted at the septa, eight to 

 nine-septate, -005' — 007' long, -0007' — 0008' broad in the widest 

 part, greenish.

This is a very singular species. The fungus occurs on both sides 

 of the leaf, but is more abundant on the upper surface. The 

 flocci are short and thick and occasionally branched. The septa 

 occur in the broad part of the spore, the upper part being much 

 narrowed . Occasionally a cell is divided by a longitudinal septum. 

 Cercospora Daturje, n. sp. 



Spots suborbicular or irregular, varying in color from cinereous 

 to reddish-brown, sometimes marked by irregular or flexuous 

 elevated lines; flocci amphigenous, scarcely tufted, about equal 

 to the spores in length ; spores rather large, narrowed upwards, 

 greenish, four to six-septate, -002' — 003' long, about -0005' broad 

 in the widest part.
