spond very well with the description given by Bessey for M. 
Grossulariz, yet it is more like this than either of the two spe- 
cies just mentioned. The following characters more nearly de- 
seribe our specimens: Perithecia scattered on both sides of the 
leaf, globose, minute, .07-.09mm. in diameter. Reticulations 
prominent. Appendages 10 to 15, prominently dichotomous, - 
to 6 times branched and spreading, clear throughout their length ; 
spread of branches equal, exceeding the diameter of the perithe- 
cia; ultimate branches often quite long, tips blunt. Asci 3-7, 
ovate, containing from 3 to 4 spores. 
6. Podosphera oxacantha DC. (P Kunzei Lévy. P tridactyla 
Wall. 
On the Persimmon and Quince. Bessey gives P. Kunzei, 
while Trelease adheres to tridactyla. In this species we follow 
Earle, who has carefully worked out the literature of the subject 
and has made a special study of this genus. See Boranicar 
Gazetrer, Vol. TX, p. 24. Neither of the above hosts are men- 
tioned in any of the reports which I have at hand. The Per- 
simmon is the first host outside of Rosacee upon which this spe- 
cies has been found. The perithecia, however, are few and scat- 
description of Earle more nearly includes it. The speci- 
men from the Quince gives the following characters: Amphi- 
genous, fruiting on both sides of the leaf, abundant especially on 
the upper side. Perithecia dark brown, .08mm. in diameter. 
Appendages about as long as the diameter of the perithecia, 5 to 
16, colored for more than half their length, 3 to 4 times branched. 
7. Phyllactinia suffulta Reb. (P. guttata Lév.) 
On leaves of Dogwood and Hazel; very abundant on the 
latter, 
8. Spherotheca Castagnei Lév. 
n Taraxacum Dens-leonis, Bidens frondosa, B. chrysan- 
themoides, Hieracium, Lactuea, Erigeron. All of these, except- 
ing the first two, are new hosts. Cooke’s description is not suf- 
ficient to include all these forms. I make the following notes 
from our specimens: Mycelium often abundant, web like, and 
commonly persistent. Perithecia globose, very minute, but vary- 
Ing in size, .07 to .10mm. in diameter, on both sides of the leaves 
and often on the branches and stems, abundant in pate es. Ap- 
pendages equalling or exceeding the diameter of the perithecia. 
Ascus with few spores, generally 8.
