siderably smaller than represented by Burnap (Bot. Gaz. 23:189, 
March 1897) who gives them as 15-18 x 8-10 /x. Our measure¬ 
ments are 10-15 x 8-10 n. Lloyd (Myc. Notes, 13:126, Feb. 
1903) says the spores vary “much as to size in specimens from 
different localities, and even in the same specimen. West Vir¬ 
ginia specimens 10-14 x 6-8 mic. Massachusetts specimens 12- 
20 x 6-8 mic.” 
The figures here presented, prepared by Miss Clara G. Mark, 
show the two Connecticut plants natural size, as seen from the 
side and viewed from above. The spores shown to the right are 
magnified 250 diameters. 
Since Burnap’s study of the American species ( 1 . c.) the 
number has been increased from three to four by the publication 
of a new one, namely, Calostoma microsporum by Professor At¬ 
kinson in the Journal of Mycology, 9:16, Feb. 1903. This he 
says resembles in the gross characters of the plant, C. ravenelii, 
but the spores are smaller; in the latter they are quite variable in 
size, 7-33 x 5-19 ^ ; in C. microsporum they are 6-10 x 3J-5 V, 
and do not show such great variations. A revised Key of the 
American species would be as follows: 
Calostoma.

Abundance of Darluca filum. —At one of the large com¬ 
mercial greenhouses in. Columbus, Ohio, I had opportunity some 
time ago to see an unusual quantity of Uromyces carophyllinus 
on Carnation plants. There was a separate section of the green¬ 
house devoted to carnation growing, and the attack was so severe 
that comparatively few flowers were obtained for market. Many 
of the plants—in fact many beds of them—were literally black¬ 
ened by the Rust, and their care by the florist had been aban¬ 
doned. Desiring some of the Carnation Rust I returned in a 
week prepared to carry away a large quantity but was disap¬ 
pointed in securing the valuable booty. Not a single good herbar¬ 
ium specimen, or suitable material for class use, could be secured. 
The peculiar color of the affected plants raised suspicion at first 
sight, and inspection showed that the uredineous sori were riot¬ 
ously invaded by Darluca filum—but then I secured an ample 
quantity of this for the Ohio Fungi exsiccati.
