Professor Peck writes to me: “This plant, by reason of its rather tough substance, has commonly been referred to Lentinus, under the name L. Lecomtei Schw., but this reference is scarcely satisfactory to me, since the edge of the lamellæ is scarcely at all serrate as required by that genus. It seems to me it would go better under the genus Panus. It is variable—sometimes eccentric or even lateral. It is sometimes called Lentinus strigosus, but I do not think the two are distinct species, however distinct they may be in form.” February 26, 1894. Like all Lentinus the present species is rather tough, yet chopped into small pieces, well cooked and seasoned, it is quite equal to P. ostreatus and many others of high renown. (Plate LIII.) [Illustration: LENTINUS TIGRINUS. About one-half natural size. ] =L. tigri´nus= Fr.—_tigris_, a tiger. From the markings. =Pileus= commonly 2 in. broad, white, _variegated_ with somewhat adpressed, _blackish_, _hairy squamules_, fleshy-coriaceous, _thin_, commonly orbicular and central, at first convexo-plane, _umbilicate, at length funnel-shaped_, often split at the margin when dry. =Stem= about 2 in. long, _thin_, solid, very hard, commonly attenuated downward, minutely _squamulose_, whitish, often ascending and becoming dingy-brown at the base, at first furnished _at the apex with an entire reflexed ring_, _which soon falls off_. =Gills= decurrent (_by no means sinuate_), narrow, crowded, unequal, toothed like a saw, white. Somewhat gregarious, even cespitose, thinner and more coriaceous and regular than L. lepideus B., wholly blackish with squamules. _Fries._ On old stumps. Rare. _Stevenson._ When fresh very tender and easily torn, when dry coriaceous. _Sow._ Smell strong, acrid, like that of some Lactarii. _M.J.B._ =Spores= 6.6×3.3µ _Morgan_; elliptical, smooth, 7×3.5µ _Massee._ Agreeable taste and odor, eaten in Europe. _Roques._ Edible, tough when old and never very delicate or digestible.—_M. C. Cooke._ Not found in sufficient quantity to test. =L. lepi´deus= Fr. _Gr_—scaly. (Plate XVI, fig. 3, 4, p. 52.) =Pileus= 2–4 in. broad, pallid-ochraceous, variegated with adpressed, _darker, spot-like scales, fleshy_, very _compact_ and firm, _irregular_, commonly excentric, convex then depressed, but not truly umbilicate, sometimes broken up into cracks. =Flesh= pliant, white. =Stem= short, commonly 1 in. long, solid, _stout, very irregularly formed_, almost woody, tomentose-scaly, whitish, rooted at the base, _at the first furnished with a veil toward the apex_. =Gills= decurrent, but _sinuate behind_, crowded broad, transversely striate, whitish, edge torn into teeth. Odor pleasant. _Fries._ =Spores= 11×5µ _W.G.S._, 7×3µ. _Massee._
