Agaricus dichromus Berk. & Curt. Jour. Linn. Soc. 10: 292. 

 • 1868. 



Known only from specimens collected by Wright on dead wood 

 in Cuba. The spores are broadly ovoid, smooth, opaque, dis- 

 tinctly purplish-brown under the microscope, 7 X 4-5 



4. Psilocybe plutonia (Berk. & Curt.) Sacc. Syll. Fung. 5: 



1056. 1887 



Agaricus plutonius Berk. & Curt. Jour. Linn. Soc. 10: 292. 1868. 



Known only from Wright's single collection on decayed wood 

 in Cuba. The spores were described as subglobose, but are now 

 distinctly angular, as in Entoloma, decidedly purplish-brown 

 under the microscope, uniguttulate, 4jjl in diameter. If this 

 angularity is not due to shrinkage, the species is readily dis- 

 tinguished by it and is quite anomalous. Psathyra cubispora, 

 which occurs on moist ground in South America, may be referred 

 to in this connection. 



Doubtful Species 



Psilocybe subviridis (Berk. & Curt.) Sacc. Syll. Fung. 5: 

 1051. 1887. {Agaricus subviridis Berk. & Curt. Jour. Linn. 

 Soc. 10: 292. 1868.) Described from specimens collected by 

 Wright on decayed wood in Cuba. The types at Kew are rather 

 poor and the description omits many important characters, such 

 as taste, and the color of the context and lamellae ; but the spores 

 are ellipsoid or ovoid, smooth, very pale purplish-brown with a 

 yellowish tint under the microscope, 7X4/^.
