TRICHIA 277 



Sporangia gregarious, sometimes closely so, sometimes scattered, 

 turbinate, shining olive or olivaceous brown, stipitate ; stipe gener- 

 ally elongate, concolorous above, dark brown below, hollow, i. e. 

 filled with spore-like cells; capillitial mass yellowish or olivaceous 

 yellow, the elaters perfectly smooth, long fusiform, tapering gradually 

 to the long, slender taeniate apices, simple or often branched, adorn- 

 ed with spirals three, w^hich wind evenly but somewhat distantly; 

 spore-mass olivaceous or ochraceous, spores under the lens, pale, 

 minutely delicately reticulate, 10-12 ju,. 



One of our largest and most common species, in form and size 

 resembling H. clavata, but immediately distinguished by its color. 

 The capillitium is like that of T. botrytis, but differs in the more 

 open sculpture and the longer and smoother unwound tips. The 

 episporic net is a constant character in all the specimens examined. 

 This feature reminds of T. scabra. 



This is, of course, our familiar T. fallax of all authors from Per- 

 soon down. The earliest unmistakable reference to this species is 

 Hedwig, /. c. But Batsch, in 1789, had used the same combination 

 to describe a real pufif-ball, so that Hedwig's name was already a 

 synonym. The specific name here adopted is next in point of priority, 

 although Persoon discarded it the year following, substituting fallax, 

 because he had mistaken the genus. 



Not rare. New England, Toronto; west to the Black Hills and 

 Washington, Oregon, California, south to the Carolinas and Kansas; 

 Jalapa, Mexico.
