were gathered, and those scarcely mature, the spores being still closely 
compacted. The peridium looks very like a specimen of Spheria 
nummularia, its granulations reminding one of Ret. maxima. In the 
colour of its spores it approaches A. olivacea, but recedes in its other 
characters, as, for instance, in its dark granulated, not PM and 
hyaline peridium. 
354. Ustilago Emodensis, n. s.; sporis ellipticis ovatisve levibus 
minimis saturate lilacinis filamentis radiantibus furcatis immixtis. 
Has. On some Polygonum. Tonglo, 10,000 feet. 
Forming a lobed tubercle, apparently exterior to the ochrea, but 
probably formed by a short deformed spike bursting through the 
sheath, every triple nodule of which corresponds with the original 
site of a flower-bud, no trace, however, being left of floral envelopes 
or stamens. Spores ovate or elliptic, deep lilac, smooth, very minute, 
traversed by radiating forked threads. 
Of this remarkable production I have seen a single specimen only, 
from which, in the absence of all information as to the normal mode 
of inflorescence, I can form no judgment as to the nature of the 
change produced by the parasite. It is certainly closely allied to 
U. Candollei, but differs in the presence of the forked threads and the 
different mode of growth. The spores, too, are far redder and have 
not a third of the diameter of those of that species. I do not sup- 
pose that the threads have any real connection with the fungus, but 
they differ very greatly from the columella, which exists in the described 
forms of the species just mentioned. 
* Leotia lubrica, Pers. Syn. p. 613. Hook. fil., No. 131, cum ic. 
Has. On clay banks. Sinchul, 8,600 feet. October. Rare. 
In habit and fructification exactly like the well-known species. 
The colours are brighter than usual, the stem being orange, and the 
head of a metallic blue-black. 
855. Peziza Darjeelensis, n.s.; cupula expansa subcochleata um- 
brina, extus pallida aleuriata; sporidiis minoribus scabro-punctatis, - 
endosporio simplici. 
Has. On the ground. Darjeeling. 
Cup two inches or more broad, at first subcochlezeform, split on one 
. side, at length expanded, umber-brown; externally paler, mealy. Asci 
slender; sporidia small, elliptie, beset with minute scabrous points. 
Resembling at first sight P. repanda, but the sporidia are much
