7. Clitocybe Broadwayi sp. nov. 



Gregarious to subcespitose, rather large, abundant, strongly sug- 

 gesting Tricholoma alboflavidum, but with distinctly decurrent 

 gills ; pileus thin, convex, often indented on the side next to the 

 stipe owing to its clustered arrangement, 5-8 cm. broad ; surface 

 glabrous, faintly radiate-striate, dry, white or pale-isabelline, 

 depressed to umbilicate ; margin incurved, concolorous, blackening 

 when bruised ; lamellae decurrent, close, narrow, white ; spores 

 ellipsoid, smooth, hyaline, 5-7 X 3-5— 4-5 stipe curved, cylindric, 

 usually equal, glabrous, toughish, slightly reddish-brown, twisted 

 and finely grooved when dry, suggesting asbestos, 5-7 cm. long, 

 2-4 mm. thick. 



Type collected on the ground among leaves in a cocoa planta- 

 tion at Tanteen, St. George's, Grenada, August 23, 1905, W. E. 

 Broadway. Also collected in Grenada by Broadway in Septem- 

 ber, 1905. 



Doubtful and Excluded Species 



Most of these will be found treated under Monadelphus, Om- 

 phalia, and Marasmius. Clitocybe rivulosa, reported from the 

 West Indies by Fries, is a European plant, and no specimens of it 

 from tropical America have been seen in any of the herbaria 

 examined. Clitocybe pachylus Berk. & Curt., from Cuba, is prob- 

 ably undescribed. 



3. Monadelphus Earle, Bull. N. Y. Bot. Garden 5 : 432. 1909 



This genus was founded by Earle to receive the cespitose species 

 of Clitocybe, the type being C. illudens.
