294 NORTH AMERICAN FLORA [VoLUME 9 
somewhat fusiform, smooth, hyaline, 4-5 X1.5-2 u: stipe eccentric owing to its position on the 
host, short, thick, woody, solitary, subequal, cylindric, marked with the decurrent lamellae, 
minutely tomentose, especially at the base, concolorous, 1-2 cm. long, about 1 cm. thick. 
Type collected on dead wood in British Honduras during the winter, 1907, Morton E. Peck (herb. 
N. Y. Bot. Gard.). 
DIstRIBUTION: Known only from the type locality. 
DOUBTFUL SPECIES 
Agaricus denticulatus Schw. Schr. Nat. Ges. Leipzig 1: 81. 1822. Found on rotten logs 
in North Carolina and described as brownish-yellow, squamose, 1.2 cm. broad; lamellae yellow- 
ish, elegantly serrate; stipe short, subsquamose. 
Lentinus chaetoloma Fries, Nova Acta Soc. Sci. Upsal. III. 1: 34. 1851. Described from 
Oersted’s collections in Costa Rica. Fries does not mention a figure, and no specimens were 
found. It is probably a thin, almost denuded form of L. crinitus. 
Lentinus Curtisti Sacc. & Cub.; Sacc. Syll. Fung. 5: 595. 1887. (Lentinus omphalodes 
Berk. & Curt.; Berk. Grevillea 1: 33. 1872. Not L. omphalodes Fries, 1863.) Found in 
Pennsylvania and described as infundibuliform, 12-13 mm. broad; lamellae entire, decur- 
rent; stipe slender, fibrillose below, 12-28 mm. long and 2 mm. thick. Two small specimens 
are at Kew, collected by Michener. 
Lentinus flaccidus Fries, Nova Acta Soc. Sci. Upsal. III. 1: 226. 1851. From the island 
of St. Thomas; described as deeply umbilicate, glabrous, pallid, 5-8 cm. broad; lamellae de- 
current, distant; stipe short, subeccentric. This apparently corresponds fairly well with forms 
of L. hirtus. 
Lentinus fuligineus Berk. & Curt. Jour. Linn. Soc. 10: 302. 1868. Found on logs in 
Cuba and described as infundibuliform, glabrous, fuliginous, 5 cm. broad; lamellae narrow, 
entire; stipe striate, glabrous, 2.5 cm. long. 
Lentinus furfurosus Fries, Epicr. Myc. 391. 1838. Based on Agaricus omphalomorphus 
Mont. from Chile. Specimens from Chile sent to Fries by Montagne are still at Upsala, but 
none so labeled were found from Costa Rica. 
Lentinus glabratus Mont. Pl. Cell. Cuba 424. 1842. Type specimens at Paris collected 
by Sagra in Cuba very much resemble Lentinula detonsa, but differ in having decurrent gills 
and brown, marginal hairs. It is just possible that the two species have been confused, since 
a specimen at Kew sent by Montagne as Lentinus glabratus seems referable rather to Lentinula 
detonsa. 
Lentinus Michenert Berk. & Curt. Ann. Mag. Nat. Hist. II. 12: 427. 1853. Collected 
on dead wood in Pennsylvania and described as umbilicate, 5 cm. broad, glabrous, ochraceous; 
lamellae short-decurrent, broad, lacerate; stipe 2.5 cm. long, fusco-umbrinous, spongy-velvety. 
Lentinus microspermus Peck, Bull. Torrey Club 33: 216. 1906. Found on dead wood at 
Creve Coeur, Missouri. Not a Lentinus. 
Lentinus obconicus Peck, Bull. Torrey Club 33: 215. 1906. Found on decaying wood at 
Minneapolis, Minnesota. Apparently very near L. carneotomentosus. 
Lentinus parvulus Berk. & Curt. Ann. Mag. Nat Hist. II. 12: 426. 1853. Described 
from Pennsylvania as cespitose, 1-2.5 em. broad, infundibuliform, glabrous; lamellae dicho- 
tomous, decurrent, white; stipe slender, lanuginose, 2.5 cm. long. 
Lentinus pulcherrimus Sumst. Torreya 7: 60. 1907. 
Lentinus Robinsonit Mont. Syll. Crypt. 147. 1856. Found in humus near Columbus, 
Ohio. The description reads like that of a species of Chanterel. 
Lentinus Sullivantit Mont. Syll. Crypt. 146. 1856. Found on rotten logs near Columbus, 
Ohio. The description leaves little doubt that this is the same plant as L. levis. 
Lentinus Underwoodit Peck, Bull. Torrey Club 23: 414. 1896. Collected at Tuskegee, 
Alabama, on oak wood. The type at Albany is in bad condition and no specimens have been 
found in the Underwood herbarium. Dr. House thinks the species is near L. Jevis, the surface 
showing no real scales and the lamellae being more distant than in Lentodium Squamosum.
