oval, strongly rostrate. This appears to be so distinct from any description 
given that I have named it as new. Not uncommon. 
Erysiphe, ( Plate IV, Fig. 1.) On Aster puniceus. One con- 
ceptacle alone found. 
E. lamprocarpa, Lev. On Phlox (Old Maid’s Pink.) 
E. mcirtii, Lk. Very common on leaves and stems of peas. The 
cultivation of garden peas in late summer and autumn is precluded from 
the effects of this fungus as much as from the weevil which infests them. 
Erotium herbariorum, Lk. On plants in cabinet. Common every- 
where. 
These are all that were found in these two families, except one of the 
latter on leaves of Liriodendron tulipifera , whbh was not matured enough 
to determine. Botry opium pulchrum should not have been given among 
the parasitic plants, as it is only found on decaying herbage. The figure is 
more slender and the branches longer than Cooke’s figure. The species may 
not*be correct. Fear of occupying too much space causes the omission of 
further notes.
