Murrill: Agaricaceae of Tropical North America 279 



This genus differs from Pluteus in having sinuate or adnexed 

 lamellae, corresponding to Tricholoma in the white-spored series. 

 The species are abundant in temperate regions, but none have 

 heretofore been reported from tropical America. 



i. Entoloma Murraii (Berk. & Curt.) Sacc. Syll. Fung. 14:

Agaricus (Entoloma) Murraii Berk. & Curt. Ann. Mag. Nat. 

 Hist. III. 4: 289. 1859. 



First collected in New England by Murray, and later found as 

 far north as Maine and as far south as Alabama. With the habit 

 and brilliant coloring of Hydrocybe, it unites a peculiar shape 

 and remarkable many-angled or irregularly stellate spores. The 

 coloring and striation of the cap varies with age, climate, etc.
