We have not seen this in the living state and adapt the follow- 

 ing from Peck's description of C. exigua : 



Very small ; stem slender, dichotomously or somewhat irregu- 

 larly branching, white, branches delicate lavender color or the 

 lower white toward the base, tips subacute, axils rounded ; spores 

 minute, globose, 2-2. 5\i broad. Among fallen leaves in woods. 

 Floodwood. September. The whole plant is scarcely more than 

 six lines high. The coloring of the upper part is very delicate 

 and beautiful. 



We have examined the type of C. exigua and find the plants to 

 be minute, delicate, branched, almost hair-like, with a few minute 

 hyaline spores (many large brown spores of a mold intermixed). 

 The plants are springing from fallen leaves of deciduous woods. 



There is no doubt that it is the same as the species entered 

 above as synonyms, of which C. pulchella has precedence. As 

 Cotton and Wakefield give certain structural details not mentioned 

 by others, we quote the following from them (as C. Bizzozeriana) :
