A NEW PINE LEAF RUST, 
( Coleosporiumpini, n. s.) 
By B. T. Galloway. 
Early in May of the present year we found on the leaves of Pinus 
inops , near Washington, a Coleosporium which appears to be new, and 
which may be briefly characterized as follows: 
Coleosporium pini, n. s. —III Amphigenous. Sori reddish orange, 
1 to 5 mm long, or when confluent frequently attaining a length of 10 mm 
or more; spores irregularly clavate, smooth, 2 to 4 celled, 70-125 by 
18-25^. Forming yellow spots 4 to 25 mm or more long at or near the 
ends of Pinus inops leaves. The spores germinate readily in moist air 
by sending out one unseptate promycelium from each cell; upon the 
free ends of these tubes, which are of various lengths, the orange red 
sporidia are borne. Finding the Coleosporium nearly always associated 
with Peridermium cerebrum , Pk. led me to believe that it might be the 
teleutosporic form of this fungus. Cultures are being made to settle 
this aud other questions connected with these interesting parasites, but 
as it will be at least a year before definite results can be obtained we 
have thought it best to briefly describe the Coleosporium here.

A NEW HOLLYHOCK RUST. 
(Plate x.) 
The Hollyhock ( Althcea rosea) has several enemies among fungi. The 
most dangerous diseases of this ornamental plant are, as far as known, 
caused by Puccinia malvacearum , Montague; Cercospora althceina , Sacc.* 
Recently Miss South worth has directed attention to a new and danger¬ 
ous disease of the Hollyhock caused by Colletotriclium malvarum, t (Br. 
& Casp.) South. 
In the following lines I will describe a new Hollyhock disease caused 
by a fungus closely allied to and fully as dangerous as Puccinia malva- 
cearum , Mont. As P. malvacearum lias found its way from South Amer¬ 
ica to Europe, it is not impossible that P. lieterogenea , n. s., may also 
attack the Malvas of the Old World. 
More than a year ago, while passing over the road between Guayaquil 
and Quito for the first time, I observed at several stations, viz, Chimbo, 
Guaranda, Mocha, etc., a rust on Malva which presented considerable
