ered in the paper is named by Ernst as Candelillo, and its 
fungous cause is described rather fully by him as Erysiphe 
scandens, with an illustration of mycelium bearing conidia. 
Specimens of coffee leaves affected with ‘‘Candelillo’’ were 
sent to Kew Herbarium by Ernst; these specimens were 
studied by Cooke, who determined the fungus as his Pellicu- 
laria koleroga. 
3. In 1912, Kuijper concluded that the fungous leaf blight 
of coffee in Porto Rico is distinct from that causing Candelillo 
in Venezuela and different from Pellicularia koleroga of 
India. Shortly afterward G. L. Fawcett obtained through 
E. J. Butler specimens of the coffee blight fungus from 
Mysore, the type locality, and concluded that the Porto Rican 
fungus agreed in every way with that from Mysore, but that 
the Venezuelan fungus is distinct. Neither of these authors 
noted the basidiomycetous nature of the fungus which they 
studied, although it is obvious from the illustration by Faw- 
cett that he figured young basidia as hold-fast cells. 
Upon writing to the Kew Herbarium for a fragment of 
the type of Pellicularia koleroga Cooke, in order that I might 
determine for the systematic account of North American 
species of Corticium the status of the Corticium parasitic 
upon coffee leaves at Mayaguez, the Director of Kew Her- 
barium kindly presented me with small portions of the Vene- 
zuelan specimens which had been received from Ernst and 
regretted that the Mysore specimen was now so fragmentary 
that only microscopical preparations from it could be spared. 
Miss Wakefield very kindly sent with these preparations 
drawings which she made of the basidia, spores, and hyphae 
from the above-mentioned preparation as soon as prepared, 
drawings of the same parts in the Ernst Candelillo specimen, 
similar drawings and portion of a specimen on coffee col- 
lected in Colombia by H. T. Dawe, and other drawings of the 
same organs based on Trinidad specimens collected by 
J. Н. Hart.

Mr. H. E. Thomas, at Mayaguez, Porto Rico, in August, 1915,
