Cranberry, North Carolina (Lancaster Thomas.) 

 This species is also allied to C. radiatum. The ridges which cause 

 the peculiar shrivelled appearance of the surface of the sporangia are 

 not the result of the drying of immature sporangia, but are pres- 

 ent in all cases. They are morphological in character, their loca- 

 tion being indicated by grayish lines on the chalky white surface of 

 the immature sporangia from a very early period of their develop" 

 ment while they are still in a soft and plump condition. 



Craterium rubescens n. sp. 



Sporangia stipitate, about one mm. high including stipe, cylin- 

 droid or elongated cyatbiform, apex convex; sporangium-wall single, 

 dark violet-red, smooth except at the upper portion which is 

 slightly roughened by an external deposit of scattered lime 

 granules of a pale lilac color; lower third of wall ridged longi- 

 tudinally ; on spore dehiscence the apex falls away separating 

 by an irregular line in a circumscissile manner; stipe violet- 

 black, one-half the height of the sporangium, wrinkled longitu- 

 dinally, the ridges being continuous with those upon the sporangium ; 

 capillitium composed of an irregular, branched central mass of 

 violet-red lime granules, the branches connected with the sporangium- 

 wall either directly or by a scanty network of delicate colorless 

 tubules with long angular knots of red lime granules at the 

 nodes ; spores 7'5-8'5,'j. in diameter, brown-violet, epispores thick, 

 minutely warted with dark violet warts. 



Louisiana (A. B. Langlois, com. J. B. Ellis.) 



This species is allied to both C. aureum and C. lemocephalum, 

 more especially in their elongated and cylindroid forms. It is 

 distinguished from them by the Badhaniia-like character of the 

 capillitium and by the color which exhibits some shade or tone of 

 red or violet-red in every part of its structure. The color of the 

 sporangium-wall is due largely to the violet-red innate lime granules 

 which it contains. 



Craterium concinnum n. sp. 



Sporangia usually minute, stipitate, broadly funnel shaped, one- 

 half to two-thirds of a mm. in height including stipe, and one-fifth 

 to one-half of a mm. wide at the top, dehiscing by a regular cap or 

 operculum ; color variable, sometimes light or dark umber uniformly 

 diffused over the entire sporangium, sometimes dark brown on the 

 lower half of the sporangium, abruptly shading into brownish-white
