S. ochraceoflavum. I have compared a good collection of that spe- 

 cies from the Schweinitz Herbarium and another from Schweinitz 

 in the Curtis Herbarium, and find them identical. It is also like 

 plants under this name in the Curtis Herbarium from Massachusetts, 

 New York and Mississippi. The same thing from Alabama, South 

 Carolina and Cuba in the Curtis Herbarium was labelled S. hir- 

 sutum. Specimens of the latter from Europe are quite different. 

 Our plant is also like S. ochraceoflavum as represented in the Kew 

 Herbarium, where I sent some of my plants for comparison. Stereum 

 sulphuratum B. & Rav. (Journ. Linn. Soc. 10: 331. 1868) seems very 

 near. From the description the species would hardly be connected, 

 but the type of S. sulphuratum in the Curtis Herbarium from Cuba, 

 as well as a collection from Georgia, can scarcely be distinguished from 

 our plants with a hand lens. Burt finds the microscopic characters 

 of the two species to differ in several respects.

Caps from 1-2.5 cm. wide, much fused and folded and rising 

 from a common resupinate stratum; surface grayish snuff color, the 

 margin abruptly pallid; tomentose when young, the tomentum col- 

 lapsing on exposure to weather, the growing margin remaining tomen- 

 tose; obscurely marked with structural zones, especially near the 

 margin, where there may appear an interrupted blackish zone. Flesh 

 about 1 mm. thick, color of surface, fibrous and rather spongy. Hy- 

 menium thin, about 55-65[j, thick, white when young, then approach- 

 ing the cap color, becoming dark brown when bruised in the growing 

 state; texture much more firm and brittle than the flesh; furnished 

 with thick, refractive, embedded gleocystidia; cystidia also present, 

 encrusted, blunt or pointed, 3.5-4jx thick, projecting about 9-22[jl. 



Spores oval, smooth, 2.3-2.5 x 3.5-4[j,. 



Burt makes an error in not crediting this from North Carolina, 

 putting Salem, under South Carolina.
