2. Vaginata velosa (Peck) 



Amanitopsis velosa Peck, Bull. Torrey Club 22 : 485. 1895. 



This species, described from material sent from Pasadena by 

 McClatchie, is near V. vaginata, but has large whitish volval 

 patches on the buff-colored pileus. It is abundant in southern 

 California, almost to the exclusion of the common eastern spe- 

 cies.

3. Venenarius Earle, Bull. N. Y. Bot. Card. 5 : 450. 1909 



The type of Amanita is Agaricus campestris, Amanita thus 

 being a synonym of Agaricus. Earle erected the new genus 

 Venenarius for A. muscaria and other species in which the basal 

 volva breaks into fragments, leaving Leucomyces of Battarra 

 for the remaining species. More recent usage discards Bat- 

 tarra's genus as not based on binomial publication, leaving the 

 one genus Venenarius, which, in my opinion, is quite sufficient 

 for all the species of Amanita as ordinarily considered.
