Harper—Species of Lentinus in Great Lakes Region. 373 
“Pileus obconic, fleshy, sometimes slightly depressed in the cen¬ 
ter, whitish with tawny brown squamules in the center. Flesh 
white. Lamellae narrow, close, very decurrent, lacerate and den¬ 
tate on the edge. Stem long, flexuous, solid, whitish at the top, 
tawny brown and squamose toward the base. Spores oblong, 
4-5 x 8-10 ix. 
“Pileus 2.5-6 cm. broad, stem 5-8 cm. long, 6-10 mm. thick. 
Caespitose, decaying wood in a lumber yard, Minneapolis, Minn. 
“The thick flesh and obconic shape of the pileus with the long, 
decurrent lamellae are the prominent distinguishing features of 
this species. The flesh of the dried specimens cuts easily. The 
scales of the pileus are smaller than in L. lepidem Fr. It is closely 
related to L. cyathiformis (Schaefl.) Bres.” 
Note. Peck relates the species to the European Panus cyathiformis 
which is considered a Lentinus by Bresadola. It is, however, a form of 
Lentinus lepideus, and probably the same as the European L. suffrutescens 
Fr. illustrated by Schaeffer (t. 248-249), which is considered by Murrill 
(N. A. F. 9: 296) a form of L. lepideus. 
5. Plate XVI. Large plants with irregular spot-like scales on 
the pileus, decurrent lamellae and thick squarrose stems. Len¬ 
tinus magnus Pk. 
The plants grew on the ground by rotten logs in woods at 
Frankfort, Michigan. They were very large with large areolate 
scales on the pileus. The stem was squarrose with thin, flake-like 
scales. They agree with Peck’s L. magnus except that the scales 
on the pileus are darker colored. All the characters of the spores, 
basidia, and mycelium are those of L. lepideus. They grew on 
ground full of humus. The peculiar surface of the pileus and the 
thick lamellae emphasized by Peck can be seen in the photograph. 
The spores averaged 3 x 7-8/a, a little narrower than the measure¬ 
ments given by Peck. The species is described (Bull. Torrey Bot. 
Club 23: 413, 414) : 
“ Pileus thick, hard, convex, slightly depressed in the center, 
glabrous, dingy white, the surface cracking into broad areolae or 
scales, margin involute. Flesh whitish. Lamellae broad, close, 
thick, slightly decurrent, coarsely dentate or lacerate on the edge, 
pallid. Stem stout, hard, solid, squamose, slightly thickened at 
the base, colored like the pileus. Spores oblong-elliptical, 4 x 7^/*. 
Pileus 6 inches or more broad, stem about 4 inches long, 1 inch or
