of the Torrey Botanical Club. XXIX. 1902. p. 251. pl. 14— 18.) 



A systematic review with füll synonymy of the American Nldularia- 

 ceae. White recognizes four genera; which he groups as follows : 



Sporangioles attached to the inner wall of the peri- 

 di um: 



Peridium composed of 3 layers; spores mixed with filaments. 



I Cyatliia. 



Peridium composed of one homogeneous layer; spores not 



mixed with filaments IL Crucibulum. 



Sporangioles not attached to the inner wall of the 



peridium: 



Peridium thick, opening by a regulär definite mouth 111. Nidula. 

 Peridium thin, rupturing irregularly (Cyathus Hall) 



IV. Granularia, 



I. Cyathia (P. Br.) is described with 13 species, of which the follo- 



wing are new: C. dura, C. hirsuta infundibuliformis (nov. var.) 



IL Crucibulum, Tul. — The familiär C. vulgare Tul. becomes C. 



Crucibuliforme (Scop.) because of Peziza crucibuliformis Scop. 



1772. 



III. Nidula gen. nov.: Peridium composed of a Single homogeneous, 

 but layered membrane, which is at first continuous and the 

 mouth much as in Crucibulum ; sporangioles very numerous, 

 at first immersed in a glutinous substance, very closely packed- 

 entirely filling the central cavity and in no way attached to the 

 peridium wall; no filaments intermixed with the spores. 



Two species are described Nidula Candida (Pech.) and 

 Nidula microcarpa Pech, sp. nov., also one variety N. micro- 

 carpa rugispora var. nov. 



IV. Granularia Roth, with four species of which G. castanea (EIL 

 and Sw.) and G. rudis Pech, are new. 



A table showing the geographical distribution in America 

 is added. 89 figures an 4 plates illustrate many of the species.
