White : The Nidulariaceae of North America 269 



not until 1801, was the present generic name employed by Per- 

 soon * — even then only to denote a species — Cyatlms Crucibulum. 



Schweinitz was the first to report Crucibulum crucibuliformc from 

 this country under the name of Nidularia Crucibulum. He also 

 described another species, Nidularia juglandicola which though 

 retained as a good species of Crucilmlum by De Toni,t proves to 

 be a form of Crucibulum crucibuliforme, slightly larger and more 

 flaring, but otherwise similar to the type species. Though the 

 genus as represented by Crucibidum crucibuliforme is comparatively 

 common and widely distributed, it is interesting to note in contrast 

 with the genus Cyathia, which is very prolific of species, that only 

 one other species has been described, viz., Crucibulum simile 

 Massee % from New Zealand and Australia, and even this is said 

 to resemble Crucibtdutn crucibidiforme closely. 



Bulliard § says that there are two varieties of Crucibulum 

 both of which he figures, one glabrous, almost as smooth inside 

 as out, the other smooth inside but somewhat tomentose on 

 the outside, and always larger and more yellow than the first 

 It has been noticed in examining quite a number of specimens 

 from different localities that those collected in one place often vary 

 greatly in size and color, and in the nature of the tomentose outer 

 surface of the peridium. Cooke, || in 1 879, described a variety which 

 he calls lanosum, and which De Toni says might possibly be Bui- 

 Hard's second variety (figured on//. 4.0) but as Cooke described it as 

 "paler than in the usual form" this disposition cannot be correct.
