REVISION OF THE NORTH AMERICAN HYDNACEAE 169 
to ash-gray, lighter at the tips, 1.5 mm. or less long, 0.3 mm. wide 
at the base; spores subglobose, echinulate, white, about 3.5 и 
wide; taste mild, odor in drying very fragrant, resembling slip- 
pery elm, and persistent in the dried plants for years. 
Нав.: Among fallen leaves in mixed woods. Aug. 
Rance: Connecticut, Earle гоо, White, Underwood; New 
York, Peck, Banker. 
The type plant is in the N. Y. State Herbarium at Albany. 
The species is near Р. graveolens (Delast.), from which it may be 
distinguished by its subsessile habit and its thickened woolly pu- 
bescent pileus. From P. alboniger (Peck), some forms of which it 
also resembles, it may be distinguished by its brownish not blackish 
substance, and by its dry not hygrophanous character. 
4. Phellodon graveolens (Delast.)

brous, azonate, smoky with fuscous blotches toward center, creamy- 
white at margin, margin incurved, sterile, subrepand ; substance 
soft spongy at top of pileus, more compact below and in the center 
of stem, smoky ; stem short, subcentral, somewhat deformed, not 
bulbous, fuscous, pubescent, 2 cm. long, 0.8 cm. wide ; teeth short, 
creamy-white to ash-gray, subdecurrent, less than 1 mm. long ; 
spores subglobose, echinulate, white, 3.5 # wide ; odor fragrant.

This species has given me more trouble than any other 
in the family. The above description is drawn up from ded 
plants which appear to have the essential characters of Delastre s 
plant and conform best to Fries’ figure. These forms are of con- 
stant and uniform character as shown in the above distribution, but 
in the collections they are more or less mixed up with other very 
different appearing plants. It is surprising to see the great variety 
in the forms that have been referred to this species. Apparently 
everything witha strong odor has been referred to Æ panum grovertens 
Delast., a practice which seems to have had its origin in СооКе 8
