The young plant consists of a swollen odlong-clavate stem cap- 
ped with the minute white pileus, which is then less than the 
diameter of the stem itself, but, as the pileus expands, the stem 
elongates and becomes more slender. 
Near M. Vaillantii, ., but the lamellae are closer and narrower, 
the pileus smaller, and the stem is contracted above and white at base. 
16. Boletus squamulosus, n. sp.—Pileus convex, 2’-3’ across, 
covered with a dull red, separable, viscose pellicle—flesh soft, dull 
yellowish-white when freshly broken, soon turning greenish-blue 
and finally drying to a permanent yellow—tubes of unequal size, not 
‘large, somewhat depressed around the stem, straw color, turning 
greenish-blue when bruised, but, like the flesh of the pileus, becom- 
ing at length permanently yellow. Stem solid, 3’ long, }’ thick, 
rather enlarged below, yellow within and at the very summit, surface 
covered, except the yellow summit, with a red sqguamulose coat, 
Resembles B. Frostii, Rus., but distinguished by the color of the 
tubes and the different covering of the stem. Spores elliptic, about 
-0007’ long, one end a little bent. In dry oak and pine woods, 
July, August.

Lycoperdon Warnei, Pk%.—Peridium large, three to four inches 
high and nearly as broad, sessile, thick, scaly, obovate, whitish; spores 
snuff-brown, subglobose inclining to ovate, .00025 to .0003 inch long. A 
Ground among nettles. Chicago. JZ & Warne. Of this spe. \ 
cies I have seen dried specimens only, but so far as the characters 
can be ascertained, it is a remarkable plant differing from all 
ordinary forms of Lycoperdon in its peculiarly large spores and in 
its singular capillitium, which is made up of membranous plates or 
folds rather than of filaments. It may hereafter be deemed necessary 
to separate it as the type of a new genus. Mr. Warne remarks that 
in size and shape it is not unlike a beel’s heart. 
Septoria Besseyi, Pk.—Hypophyllous; perithecia more or less 
abundantly scattered over the whole lower surface of the leaf, 
slightly prominent, at first pale ferruginous or subochraceous, then 
black ; spores large, cylindrical, obtuse, moderately curved, usually 
containing several nucleoli, .0016 to .0022 inch long, about .00016 inch 
broad, oozing out in whitish or pinkish white masses or in short 
thick tendrils. Living leaves of young ash trees. Ames, Iowa.

This species is doubtless closely related to Septoria Fraxini, but 
it differs so much in habit, judging from the description of that 
species, that I have felt constrained to consider it distinct. The 
upper surface of the leaf is mottled with minute yellowish spots. 
Both this and the preceding species are dedicated to their respective 
discovereys.

Hysterium Cookeianum, x. sp.—Perithecia erumpent, and at 
length entirely superficial, black, not striate, linear-elongated, ends 
acute; lips narrow, slightly swollen, edges somewhat remote; asct
