Agaricaceae of Tropical North America

scribed from specimens collected among straw on the island of 

 St. Croix, Danish West Indies. Specimens collected later on 

 the same island by Oersted were referred to this species by Fries 

 as variety praelonga; and the figure of this variety at Copen- 

 hagen, drawn by Oersted, is the only thing I have found outside 

 of the description to throw light upon the species. 



The figure reminds me very forcibly of Paneolus solidipes 

 Peck. The description of the species refers to the solid stipe and 

 to the fact that the pileus sometimes becomes areolate-corrugate, 

 but the surface is said to be yellow or white in alcohol, while 

 the drawing of the variety shows it to be avellaneo'us, and in P. 

 solidipes it is white. Fries evidently put his species in the genus 

 Psilocybe because of the " livid-black " lamellae, although he de- 

 scribed the spores as black. If type specimens were available, 

 the spores could be examined and the whole question settled. 



Psilocybe fortunafa (Cooke) Sacc. Syll. Fung. 5: 1056. 1887. 

 (Agaricus fortunatus Cooke, Grevillea 9: 100. 1881.) De- 

 scribed from specimens collected on the ground at Rio de Janiero 

 Brazil, by Glaziou, and reported from St. Vincent by Massee, 

 who may have confused it with C. solidipes, the spores of the 

 two being the same. Unfortunately, the color of P. fortunata 

 is not given. 



For the convenience of those who prefer the older nomen- 

 clature, the following species described as new in Atylospora are 

 transferred to Psathyra:
