larger spores, which are covered with flexuous ridges rather than papille. 
U. excavata, as far as we know, has not with certainty been observed in 
America. Neither has the common Melampsora, found on Huphorbie 
in Europe, been observed near Boston. There is, however, a Melam- 
psora on Huphorbie in the Southern States, which seems to differ from 
that of Europe. 
A Uromyces is found on Asclepias Cornuti, which does not agree 
with Uredo Asclepiadis, Schw. It seems to have been first mentioned 
in the 23d Report of the “ Botanist of New York State,” and described 
as Trichobasis Howei. A species, Uromyces Asclepiades, is described 
by Cooke, from Cape Elizabeth, Me.; but the description does not 
agree with the species found near Boston, in which the spores are 
marked with small protuberances. Uredo Iridis, Schw., which is 
common on Jris versicolor, was watched from June to February, in 
hopes of discovering the teleutospores, but without success. Uredo- 
spores are produced all summer, and in the autumn they fall from 
their attachments, and are not succeeded either by a Uromyces or a 
Puccinia. It is difficult to understand in what respect Trichobasis 
Tridecola, Peck., differs from Uredo Jridis, Schw. 
GASTEROMYCETES. — On page 483, Vol. I. of the “Bulletin” we 
mentioned Phallus indusiatus, Bosc, as occurring near New Haven. 
We intended to have written P. duplicatus, Bosc. We were led to 
give that name to the specimens sent by Professor Eaton, from their 
resemblance to No. 5619 of the Curtis herbarium collected by C. 
Wright (244), in Connecticut. Although the specimen referred to is 
labelled P. duplicatus, it cannot be that species, as there is no veil. 
There grows not unfrequently about Boston a species which precisely 
corresponds to Bose’s figure of P. duplicatus, with a rather short, 
thick stipe, and a short veil which hangs closely about the stipe. 
There is also another form which approaches more nearly to Phallus 
indusiatus, Vent., which occurs in Cambridge. In this the veil is 
longer, the meshes are larger, and, instead of hanging close to the 
stipe, it is funnel-shaped. Phallus indusiatus of tropical America is 
not very well defined, and Schlectendal * apparently had very little 
reason for distinguishing such a number of species of the sub-genus 
Hymenophallus from a comparison in several instances of plates of 
rather a doubtful character. We believe that the form found in Cam- 
*“ Linnea,” Vol. XV.
