whitish or dusky, flocculose-pulverulent; the margin appendicu- 
late by the lacerate veil. Stipe slender, nearly equal, fibrous- 
stuffed, rufescent beneath the white pulverulence. Lamellae very 
broad, white, free, approximate; spores elliptic-oblong, 4-5 x 3 
mic. 
Growing in rich soil among old leaves in woods. New 
York. Peck. Plentiful about Preston, O. Pileus 10-15 mm - 
in diameter, the stipe 2-4 cm. long and 1-2 mm. thick. The pul¬

DESCRIPTIVE SYNOPSES OF MORGAN'S NORTH 
AMERICAN SPECIES OF MARASMUS/ 
A. P. MORGAN. 
MARASMIUS Fries. Gen. Hym. 1836. 
Fungi tough and flexible f drying up and more or less per¬ 
sistant, not putrescent, reviving when moistened. Hymenophore 
continuous with the stipe but heterogenous, descending into the 
trama; veil none. Stipe cartilaginous or horny. Lamellae tough 
and flexible, sub distant, the edge acute and entire; spores white. 
Agarics small or minute, growing for the most part upon 
wood or among the old leaves in woods. 
§ 1. COLLYBI A.— PILEUS TOUGH -FLESHY AT 
LENGTH SUBCORIACEOUS, COMMONLY SULCATE 
OR RUGULOSE, THE MARGIN AT FIRST INVOLUTE. 
STIPE SUBCARTILAGINOUS. LAMELLAE ADNATE 
OR NEARLY FREE. 
I. SCORTEI. Stipe solid or medullate-stuffed, then hol¬ 
low, fibrous within, externally a detersile villosity clothing the 
cartilaginous cuticle. Lamellae seceding-free. 
A. STIPE WOOLLY OR STRIGOSE AT THE BASE. 
a. Lamellae sub distant. 1-7. [Species Numbers.] 
b. Lamellae rather close. 8-14. 
B. STIPE NAKED AT THE BASE OFTEN COM¬ 
POSED OF TWISTED FIBRES. 15-18. 
II. TERGINI. Stipe rooting , definitely tubularnot 
fibrous, but manifestly cartilaginous. Lamellae seceding-free. 
Pileus thinner than those of the former, hygrophanous 
* This should have immediately followed the article to which it per¬ 
tains— these synoptic descriptions serving well for a key to the species. 
As a separate it can be placed with the separate of the monograph. —
