JOURNAL OF MYCOLOGY. 
[Vol. IV, NOS. 2, 3, 
The following are all the species (14) which have been described as 
found in the United States at this time. Fries gives only five of these in 
his Ilym. Europ., viz.: Nos. 1,2,5,6 and9. Panusrudis, B. &C., is given 
in Sprague’s list of New England fungi, but a description was never 
published, and the name is occupied by Fries, Ilym. Eur., p. 489; it may 
have been a mistake for Paxillus rudis , B & C. 
* Pileus irregular, stem excentric, 1, 2, 3, 4. 
* * Stem definitely lateral, 5, 6, 7, 8, 9. 
* * * pii eus resupinate, sessile or extended behind, 10,11,12, 13,14. 
* 1. Panus conchatus, Fr. 
Pileus 2'—4' broad, cinnamon, then becoming pale, fleshy-pliant, thin, 
unequal, excentric or dimidiate, flaccid, squamulose when old ; stem p 
long, 4" thick, unequal, often compressed, pubescent at the base; gills 
strongly decurrent in parallel lines by no means anastomosing but here 
and there branched and unequal, at first whitish or pale flesh color, at 
length ochraceous wood color, crisped when dry, csespitose, often imbri¬ 
cated and growing into each other. No form is constant. So much allied 
to P. torulosus that the real difference is not apparent. It is thinner, 
more conchate and more lobed than that species. Stevenson British 
Fungi, Vol. II, p. 159. Curtis found this in South Carolina, Frost near 
Amherst, Mass., Johnson in Minnesota, Cragin in Kansas and Morgan 
on trunks and branches of beech in the Miami Valley, Ohio. Name, 
concha , a shell, shell-shaped. 
2. Panus torulosus, Fr. 
Pileus 2'—3' broad, somewhat flesh color, but varying, rufescent- 
livid and becoming violet, entire, but very excentric, fleshy, somewhat 
compact when young, plano-infundibuliform, even, smooth; flesh pallid; 
stem short, commonly P, solid, oblique, tough, firm, commonly with gray 
but often violaceous down ; gills decurrent, somewhat distant, simple, 
separate behind, reddish, then tan color. Very changeable in form, at 
first fleshy-pliant, at length coriaceous. In the covering of the stem it 
approaches Paxillus atro-tomentosns , but there is no affinity between 
them. On old stumps. Spores 6x3 mk. W. G. Stevenson, British 
Fungi, Vol. II, p. 159. New York, Pack, 30th Rep., p. 44, on oak stumps, 
in May; Amherst, Mass., C. C. Frost; Kansas, Cragin; Minnesota, John¬ 
son. Name, torulus , a tuft of hair, from the hairy down on the stem. 
3. Panus strigosus, B. & C. 
Pileus white, 8 inches across, excentric, clothed with coarse strigose 
pubescence; margin thin; stem 2—3 inches high, 1 inch or more thick, 
strignse like the pileus; gills broad, distant, decurrent. Allied to Panus 
laevis. On oak stumps. New England, G. J. Sprague; Pennsylvania, 
Dr. Michener, Annals and Mag. N. H., October, 1859, Cent. N. A. F., No. 
99; New York, Peck, 26th Rep., p. 66; on decaying wood of deciduous 
trees, Croghan, September. It is remarkable for its large size and the dense 
hairy covering of the pileus and stem. Minnesota, 1876, Johnson, Au¬ 
gust; Maryland, Banning. Name, striga, a swath, from character of 
pubescence.
