the cultivation of the sporangia from milk-white plasmodium. The 
specimen they have kindly sent us corresponds with the type from 
Curtis in the Strassburg collection obtained from S. Carolina, and 
collected four reniform plasmodiocarps of this species at Tansterne, 
orks. ey are Olive-yellow, either uniform in colour or varie 
by yellow ridges or broken bands formed by dense deposits of lime 
in the sporangium-wall; the capillitium is of the true Badhamia 
character, consisting of a coarse ee of broad strands charged 
throughout with orange-yellow lime; the spores are purple-brown, 
spinulose, and slightly paler .on one side, 11-12 diam. The 
specimen agrees closely with — from Montpellier, and is the first
