4. Hygrophorus Peckianus, n. sp.—Odorous, rather firm, grega- 
rious or subcespitose; pileus fleshy, convex or slightly depressed 
in the centre, smooth, hygrophanous, fuliginous when moist, paler 
or buff-brown when dry, the margin decurved and sometimes wavy ; 
lamellz subdistant, broad, thick, arcuate, decurrent, pallid when 
young, becoming darker with age ; stem smooth, stuffed or hollow, 
subflexuous, often compressed and attenuated below, colored like 
the pileus; spores subglobose, rough, .0002 in. in diameter. 
Plant 1-2 in. high, pileus 5-10 lines broad; stem about 1 line 
thick, é 
Ground under Pteris aguilina. Lake Pleasant, August. 
Odor quite strong, resembling that emitted by some species of | 
Golden-eyed lace-wing flies (Chrysopha). The color of the moist 
plant is- almost exactly like that of Lactarius jfuliginosus, Fries. 
Related to Hygrophorus Cantharellus, Schw. 
5. Microspneria Viburni, Hrysiphe Viburni, Schw.?—Mycelium 
web-like ; conceptacles scattered, globose; appendages less than 
20, longer than the diameter of the conceptacles, dichotomously 
branched, the tips slightly or much curved; sporangia 6-10, with 
usually 6 spores. 4/. sparsa, Howe. Leaves of Viburnum. The 
older name is here restored. 
6. Uromyces Ari-Virginici. Uredo Ari-Virginici, Schw., Uro- 
myces Peltundre, Howe.—Sori oblong, often confluent; spores sub- 
globose, irregular, brownish, pedicels sometimes rudimentary. 
Leaves of Peltandra and Arisema. Here also the older name is re- 
stored. 
7. Spheria platanicola, 2. syp—Perithecia seated within the inner 
Dark, scattered, minute, black, subconical, the apex somewhat com- 
pressed, just piercing the epidermis ; asci cylindrical, or subclavate ; 
spores uniseriate, light brown, about 8-septate, strongly resembling 
those of Cucurbitaria elongata,Grev. Branchlets of Iatanus. 
§ 122. Lechea.—I have tor some years been engaged in‘collecting 
Specimens of this genus, which promises a greater variety of speci- 
fic forms than has generally been suspected. I think Michaux’s | 
L. racemulosa and L. tenuitolia will have to be restored, and suspect — 
that there are several other species confounded under the name of —_ 
L. minor, ° 
My principal object in writing the present note isto ask contribu. | 
tion or loan of specimens of Lechea from those who may have | 
noticed and gathered varieties of this genus. I desire to learn, © 
as nearly as pos-ible, the extent of distribution of each form, In 
Florida, near Tampa Bay, Rugel found a very rough species, with 
many stamens, having short and broad leaves, which Shuttleworth | - 
in Dr. Gray’s specimen had labelled Z. divaricata. Beyond that 
in Dr. Gray’s herbarium, I know of only one other specimen, 
which is.in Paris. . OE oe 
A number of botanists have most kindly supplied me with speci- — 
mens, but there are many parts of the Union and of Canada from 
-. which no Lecheas have reached me. I have none from Western 
_ New York, and few from the Southern Alleghanies and theadjacent 
States, where Rafinesque claims to have seen several peculiar forms. 
Does ZL. major grow in Canada?
