REVISION OF THE NoRTH AMERICAN HYDNACEAE 149 
the dried plants appear dark olivaceous brown to black. On 
comparitig the specimens, however, there appears to be no doubt 
as to the identity of the two collections. 
SPECIES DUBIAE ET INQUIRENDAE 
Hydnum canum Schwein. Syn. Fung. Car. 77. 1818. 
The specimen in the Schweinitz herbarium throws little light 
on this species as it is a mere fragment and suggests a tough cori- 
aceous plant rather than a fleshy one. Fries treated the species 
as а synonym of H. gracile апа Schweinitz himself * expressed 
doubt as to the validity of the species. 
Нуапит Сит за Berkeley, Grevillea, т: 71. 1872. South 
Carolina, Curtis, 2809. This is the type specimen which I have not 
seen. A plant found by Earle in Alabama answers in every par- 
ticular to the description but looks as though it might be a young 
plant.of S. /aevigatus (Sw.) Karst. 
The following European species have been reported from this 
country but for various reasons are excluded from the present 
enumeration : /7. subsquamosun Batsch. has been reported several 
times. New England, Sprague; Rhode Island, Bennett; Penn- 
sylvania, Schweinitz ; South Carolina, Curtis, Ravenel; Alabama, 
Peters. | Bennett's specimen is a tough coriaceous plant evidently 
closely related to H. zonatum Batsch. Schweinitz’s specimen has 
been referred in this paper to 5. /aevigatus (Sw.) Karst. there being 
no scaliness to the pileus. Тһе other collections have not been 
seen. Ж. infundibulum Swartz, has been reported from Pennsyl- 
vania, Schweinitz; Ohio, Lea, Morgan; Kentucky, Morgan. 
Schweinitz’s specimen is too nearly destroyed to furnish any satis- 
factory idea of the plant. Morgan’s Kentucky specimens may be 
of this species but seem very small. The Ohio specimens I have 
not seen. H. fusipes Pers. Pennsylvania, Schweinitz. Тһе speci- 
men appears to be a small or young specimen of S. /uligineo- 
violaceus (Kalch.) Quél. H. versipelle Fr. New York, Farman. 
The specimen appears to be a young plant of 5. Underwood.
