DACTYLIUM SUBLUTESCENS 2. Sp. 
Tufts pulvinate, sometimes confluent, pinkish-yellow or cream- 
colored ; flocci erect, simple or sparingly and obscurely septate ; 
spores apical, oblong or obovate, uniseptate, .0008—.0014 long, 
sometimes with a blunt point at the base.

The species is apparently related to D. obovatum Berk. At 
first sight the tufts appear to be erumpent, but upon closer

Spheria. In some instances white tufts of more slender branched 
flocci were associated with the others. Perhaps these are sterile 
flocci of the same plant.

Our specimens do not agree well with the description of this 
species. The flocci are not ‘‘olive-brown”’ and the spores are 
cylindrical rather than ‘‘fusiform,’’ but as they exhibit the 
bristle at the extremities of the spores, and agree essentially
