154 REVISION ОЕ THE NORTH AMERICAE HYDNACEAE 
groove, uniform cinnamon brown; margin subdeflexed, thin, even, 
substerile, occasionally with dark glabrous places ; substance felty- 
tomentose, cinnamon-brown in the upper part of pileus, hard, com- 
pact and darker in the lower part and extending through the 
central part of stem, dry; stem short, conic, 1 cm. long, 1.5-2.5 
cm. wide, surrounded at base by a dense mass of felty tomentum 
similar to upper part of pileus, penetrating the substratum and 
often as large or larger than the pileus ; surface finely tomentose, 
concolorous with pileus; teeth terete, slender, straight, tapering, 
acute, the longest midway from margin to stem, decurrent to the 
bulbous base, uniform dark or light brown, lighter at the tips, 
puberulent, 1-5 mm. long, 0.3 mm. wide, 2 to one millimeter ; 
spores subglobose, coarsely tuberculate, 4-4.5 и wide.

The above collections all represent the plant described by Peck 
and named Hydnum spongiostpes. I have long hesitated on the 
question whether the latter name should be regarded asa synonym 
of А. velutinum Fries or stand as a valid species. Saccardo’s 
account is copied from Fries’ Hymenomycetes Europaei and does 
not fit our plant in several particulars. Тһе original description 
in the Systema Mycologicum, however, more nearly corresponds 
to our plant differing only in the following points. Fries says 
* Substantia azona" ; our plant often shows obscurely internal 
zonations ; “ pileus 0.5—1 unc. latus ” ; our plants will average 3-5 
cm. wide; but perhaps most important Fries asserts “pileo in- 
fundibuliformi ” and cites “ Mich. gen. t. 72. f. 4." with the remark 
“icon bona,” a figure which shows a very deeply infundibuliform 
plant, while our plant rarely is found even markedly depressed, 
never infundibuliform. Оп the other hand Fries mentions in the 
original description but not in his later work, with respect to the 
stem ''tomento demum spongioso vestitus," а conspicuous and 
characteristic feature of our plant to which Peck in his description 
of Я. spongiosipes calls special attention. Finally while the fig- 
ures quoted by Fries as representing his plant all show a plant in-
