in the island of Dominica ; it closely resembles C. microcarpa, but 

 may be distinguished by the yellow-brown colour of the sporangia, and 

 the smaller plasmodic granules hardly 1 \x diam.

10. C. pyriformis Schrad. Nov. Gen. PI., 4 (1797). Plas- 

 modium ? Total height 1 to 1-7 mm. Sporangia gregarious, 

 turbinate or globose, stalked, 04 to 0*9 mm. diam., pinkish- 

 or yellowish-brown ; cup about one-third the height of the 

 sporangium, pale brownish-yellow, perforated and irregularly 

 toothed at the margin, or equally toothed, studded with large 

 round purple-brown plasmodic granules, 2 to 2-5 fj. diam., 

 arranged in broad lines radiating from the base or evenly 

 distributed ; nodes of the net varying in shape and size, 

 flat, polygonal, or triangular, often branching, some usually 

 not expanded, charged with dark round plasmodic granules 

 and connected by pale brownish-yellow threads. Stalk 

 stout, 05 to 1*5 mm. high, dark purple-brown. Spores pale 

 oehraceous or pinkish, almost smooth, 5 to 6 fx diam. —

The var. notabilis has been found in the United States, in Switzer- 

 land and in Portugal ; it differs from typical C. pyriformis in the 

 sporangia being always globose, the slender stalks, the delicate threads 

 of the net, and in the nodes, which, though variable in shape, are 

 usually prominent and convex ; it often approaches forms of C 

 ■tenella and C. intricate. The plasmodic granules vary in abundance 

 in different gatherings.
