BADHAMIA 33 



dish base, rugulose; sporangium well spotted and veined with lime 

 granules, thicker and orange-yellow near the base; stalk yellow or 

 yellowish red, sulcate, free from refuse deposits, 0.1-0.3 mm. high; 

 capillitium a network of tubes enclosing pale yellow or white lime 

 granules, with a few hyaline connecting threads; spores pale brownish 

 violet, very minutely warted, 10-13 ju. 



According to the author, partly or completely limeless forms may 

 occur. 



Scotland, Switzerland.

 PI. II, Fig. 34. 



Sporangia aggregated, often caespitose, discoidal to subspherical, 

 sessile or short-stipitate, flat or umbilicate below, about 0.5-0.8 mm. 

 in diameter; wall grayish white, rugulose and more or less calcareous 

 and scaly; the stalk, when present, erect or sometimes nodding, 0.1 to 

 0.7 mm. tall, black or brownish black; hypothallus scanty, columella 

 lacking; capillitium not abundant, white, the nodes somewhat ex- 

 panded; spores globose, minutely but densely spinulose, violet-brown, 

 averaging 16-17 fx in diameter. Lister cites the spore measurements as 

 10-15 /z; Schintz as 12—15 /x. Material collected by Morgan in Ohio, 

 and otherwise typical, has spores 16.5-18.5 fx in diameter. 



Chiefly on moss, the small, pale, ashen sporangia appearing on the 

 tips of the leaves. Specimens from Kansas, here referred, have pale, 

 rugose stipes, about twice the height of the sporangium. 



Not common, but cosmopolitan. Reported from New York, Ohio, 

 Kansas, South America; Europe, Asia, South Africa.

Sporangia stipitate or sessile, orbicular, discoidal, irregularly elon- 

 gated or plasmodiocarpous, averaging about 1 mm. in width, generally 

 stipitate, and when stipitate, flattened or depressed above, plane or 

 slightly umbilicate below; peridium simple, more or less translucent 

 from the varying number of innate granules, sometimes covered with 

 circular flat masses of lime, gray except the point of attachment to the 

 stipe, which is brown; stipe short, black, rough, plicate; capillitium
