and the margin thicker. Not infrequently the old sporophores 

 revive and take on an additional stratum of tubes, the new growth 

 extending outward and upward over the former margin so as to 

 entirely conceal it from view.

This highly attractive fungus has been known from ancient 

 times on account of its great abundance and brilliant coloring. 

 The type locality is given by Linnaeus as Surinam, South America, 

 but herbaria are abundantly supplied with it from most tropical 

 regions the world over. Paulet's figure is cited only because of 

 his generic name ; no drawing could be poorer than this one, 

 which seems to be only a mechanical design for the corner of his 

 plate, resembling the plant in color but in no other way. 



As to habitat and host, this species exhibits little choice, oc- 



m 



curring on standing or fallen dead trunks and structural timbers 

 of almost any kind of deciduous or evergreen tree. According to 

 Swartz, it was formerly eaten by the negroes in its young stages ; 

 but it is certainly too tough for an)' ordinary use in this way. 



Of the large number of exsiccati examined, I need mention 

 only a few : North Carolina, Raasloff ; South Carolina, Ravenel, 

 Du Bois ; Georgia, Frank, Harper ; Florida, Lloyd, Small & 

 Carter; Cuba, Underwood & Earle, Brittou, Shafer ; Jamaica, 

 Earle ; Porto Rico, Howe ; Hayti, Nash ; San Domingo, Wright ;
