back to Schrader’s name, even though he considers it in- 
appropriate. 
It has been found growing on Lrichia in Europe, Ceylon, 
N. America, and Cuba. My interest in the fungus was aroused 
by the difference in the form and size of the spores, which 
puzzled me in my attempts to classify various specimens. The 
stalk I have always found to accord with Greville’s description, 
"set with minute pellucid roundish processes.” The spores in 
Greville’s and Ditmar’s figures are small round bodies. Saccardo 
describes them as “ globosis exiguis,” and Massee, in his Fungus 
Flora, adds the exact measurement as 2-3 in diameter Speci- 
mens sent to me from Devonshire and Hampshire tally with 
the above descriptions: the stalks are beset with processes, the 
spores are globose, though smaller somewhat. They are 
extremely minute. I received still another specimen from 
Egham, in Surrey, which had a similar stalk, but the spores 
are oval in form and measure up to Su by 2. On examining 
Stilbum tomentosum in the National Herbarium at S. Ken. 
sington, I found a Ceylon specimen in the Broome collection, in 
which the spores have been drawn and measured by that careful 
worker ; they are oval in form and -oo02in. long or 5 There are 
other specimens in the Broome herbarium collected in England, 
but the spores are not figured. The difference between the 
spores of the two kinds of S¢i/4um amounts almost to a specific 
distinction, but the plants are otherwise so much alike, that it 
seems better to distinguish the second as a variety. The form 
with globose spores has the priority; the other I propose to 
name var. ovalisporum. 
LINDROTH’S CLASSIFICATION OF THE 
UREDINEA ON THE UMBELLIFER&. 
By C. B. Plowright, M.D. 
The recently published work of J. 1. Lindroth, published at 
Helsingfors, Die Umbelliferen-Uredincen, consists of a pe 
fication and description of all the known species, some eighty- 
eight in number, of uredines which attack baccarat 
plants. It may not be uninteresting to see what would be the 
arrangement of our British species under this system. hich
