due to imperfect development, but it is a constant feature 

 through a series of half a dozen gatherings, one of which 

 developed m wet weather under dense shade, and another in a 

 damp chamber in the laboratory. It is certain therefore that 

 the cracking is not due to premature drying. The Plasmo- 

 dium has been watched for several days on three occasions. 

 The sporangia are sessile, crowded, on a white hypothallus 

 which is often strongly reticulated, white, bluish- white, or 

 pinkish, 0* 6 mm. diameter ; outer wall charged with spherical 

 lime granules, inseparable from the membranous inner wall ; 

 columella wliite ; interior of the sporangium white or reddish ; 

 capillitium of dark, slender threads with paler extremities and 

 a few nodular thickenings, spores 9 to 10 ft, almost smooth ; 

 in another sporangium from the same gathering the spores 

 measure 10 to 12/^, and some are spinulose, but the majority 

 are almost smooth.

The type specimen in Herb. Peradeniya consists of two dead 

 leaves bearing crowded, flattened, circular, somewhat umbili- 

 cate, sessile sporangia ; on one leaf they are reddish-brown, on 

 the other gray or almost white ; the outer wall falls away from 

 the gray inner layer. Spores 7 ^ diameter. Tliis species has 

 not been found recently.

Berkeley and Broome's 743, 744 (Thwaites' 40 and 75) are 

 marked on one packet in Herb. Peradeniya ; this contains only 

 one specimen, a cluster of crowded, irregular plasmodiocarps 

 of C. reticulatum ; their bases are covered with large angular 

 ciystals similar to those of C. michelii. This species is common 

 in Ceylon. One collection, on hving leaves of an epiphytic 

 orchid, consists of confluent plasmodiocaqjs in patches up to
