Polyporus floridanus Berk. Ann. Mag. Nat. Hist. lO : ij6. 1843.

 Coriolus floridanus Pat. Tax. Hymen. 94. 1900. 



Described by Berkeley from specimens collected on decaying 

 deciduous trunks in Florida. Described from Mexico and South 

 Carolina by Fries in 1841, but not published until ten years later. 

 Although Fries considered his plant distinct from Berkeley's, they 

 cover the same territory and appear difficult to separate specifically. 



This species occurs on oak logs and other deciduous wood in 

 the southern United States from South Carolina to Florida and 

 along the Gulf of Mexico to Texas, It much resembles C. parga- 

 ininiis both in form and habit, but is readily distinguished by its 

 grayish slate-colored surface and smoky hymenium. In some 

 foreign herbaria it is confused with Polystictiis Friesii KL, a related 

 species described from tropical America.

The type plants of this species were collected by Ravenel in 

 South Carolina. It has since been found in other parts of the 

 southeastern United States on decayed deciduous wood of various 

 kinds. The following field notes made by Calkins in Florida are 

 of interest as supplementing the rather brief published descriptiop : 



" Tough, coriaceous, elastic, nearly plane, yellowish ^nd 

 nearly smooth above and multizonate with concentric, very shal- 



low zones ; 3-4 inches across, y^ inch thick, margin acute, sterile 



beneath. Pores pallid-white changing to yellowish, especially 

 around the margin, small, round, or in places distinctly sinuous, 



with a chanp^eable luster even nn tlip QTirf^r^ ^nH nr^f al- ^11 l;5rpr-
