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- 
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 any ordinary use in this way.

only a few: North Carolina, Raas/off ; South Carolina, Ravenel, 
Du Bois; Georgia, Frank, Harper; Florida, Lloyd, Small &
