the leaf produced by the parasite, the epidermal cell attacked simply 
enlarging within the tissue of the leaf. The species seems to be related 
to S. punctum, Schr., but we should hesitate giving a name until more 
is known of its development. 
In this connection, we would call attention to a species of Synchi- 
trium found on the leaves and stems of Hrodium cicutarium, collected 
by Dr. Edward Palmer, on the island of Guadalupe, off the coast of 
California. ‘The leaves and stems are thickly beset with brownish 
globules, which, to the naked eye, bear a striking resemblance to the 
sporangia of certain ferns. ‘The species, which is one of the most 
beautiful of the genus, has both spores, in the sense used in speaking 
of S. fulgens var. decipiens, and resting-spores. The epidermal cells 
attacked by the fungus swell up into sacks which, as in the case of 
Synchitrium Myosotidis, project from the outer surface of the leaf, but 
do not extend into its interior substance. The cells containing the 
resting-spores were, in the specimens examined, much more abundant 
than those containing the spores (zodsporangia), and differed from 
them in shape. ‘The former were more or less regularly obovate, and 
contracted at the base into a pedicel of about a quarter of their own 
length; the latter were spherical, without any pedicel, and the neigh- 
boring epidermal cells grew up so as to form a small cup around the 
lowest portion, about four-fifths of the cell, however, being entirely 
free, and rising above the adjacent cells. The zodsporangia were 
numerous, brownish-yellow in color, and rather larger than those of 
S. fulgens. The material received was not in a condition suitable for 
the study of the development. The cells containing the resting-spores 
were about .2 mm. long, including the pedicel and the surface of the 
upper portion, instead of being smooth as in S: Myosotidis, was marked 
by a number of blunt papille, whose number was variable, but 
averaging about twelve. In section it could be seen that the cell wall 
was much thinner in the papille than in other places, and it is alto- 
gether probable that the spores are discharged by the rupture of the 
apex of the papille. The resting-spores are sometimes solitary, but 
more frequently there are two or three in a cell. They measure 
065—075 mm. by .04-.05 mm., are brownish in color, oval in shape, 
and have a cell wall of considerable thickness, which is composed of 
two distinct layers, the outer of which is more deeply colored than the 
inner, and is slightly roughened on the surface. As far as we can
