DiACHEA 111 



crystalline nodules of lime. Columella clavate or conical, white 

 or brown, filled with lime like the stalk or limeless. Capillitium 

 a rather lax network of purplish brown threads spreading from 

 the columella. Spores violet-gray, marked with scattered warts, 

 7-11 fx diam. 



Type locality: Ceylon. 



Habitat: On leaves, twigs, and other ground material. 



Distribution: Canal Zone, Florida, Indiana, Kansas, Massa- 

 chusetts, New York, North Carolina, Ohio, Ontario, Puerto 

 Rico.

This species sometimes forms large developments. Southern 

 specimens, tropical and subtropical, usually have the stalks more 

 slender, the lime in the form of crystalline nodules, the columella 

 conical, and prominent scattered spines on the spores. Northern 

 specimens have a stouter stalk with the lime in granules, and a 

 clavate columella. Also, the spores are sometimes brownish, and 

 the spines on the spores while scattered, are not so dark. The 

 scattered spines on the spores, and the uniformly globose spo- 

 rangia, distinguish the form from D. leiicopodia var. glohosa. 

 Martin (Trans. Am. Mic. Soc. 55: 279. 1936) reports the Plas- 

 modium as yellow in material from the Panama Canal Zone.
