pared with the specimens collected by Professor Thaxter in Florida 
and found to be the same. The collection listed on Bidens frondosa 
does not agree exactly, having somewhat smaller spores and being 
provided with conidia. The species was originally described from 
South America on Araliaceae ? but the host was later corrected to 
Bidens leucantha. The germination, apparently, has not been 
described. 
Entyloma Floerkeae Holw. 
Entyloma Floerkeae Holw., 1 Ell. & Ev., N. A. Fungi, 2288. 1889. 
Exsiccati: Entyloma Floerkeae Holw., on Floerkea proserpinacoides , 
Ell. & Ev., N. A. Fungi, 2288 (n. sp.), Ell. & Ev., N. A. Fungi, 3237. 
Sori in leaves, yellowish, often killing tissues, showing on both 
sides, oval to circular, about 2-4 mm. in length ; spores hyaline to 
reddish yellow, ovoid to chiefly subspherical or spherical, with mod¬ 
erately thick wall, often with remains of hypha showing as a short 
appendix, smooth, 9-13 p in length; conidia hypophyllous, not 
forming a very prominent growth, slightly falcate, 12-16 p x 1.5 p. 
Host: Floerkea proserpiyiacoides, Ill., Ohio, Wise. (type). 
Stevens has listed this species from Ohio under the name “ Enty¬ 
loma proserpinacoides.'''’ As the host usually disappears early in 
the season this fungus is not commonly found later than the first 
part of June. Its presence may thus escape observation. Davis 
reports the germination. Literature : 43.

Entyloma Collinsiae Hark., Bull. Calif. Acad. Sci., 1 : 40. 1884. 
Sori in leaves, whitish, showing on both surfaces, but somewhat 
darker colored above, subcircular, thin, 1-3 mm. in diameter; spores 
tinted reddish yellow, ovoid to chiefly subspherical or spherical, 
thick walled, often with remnant of hypha showing as a short ped¬ 
icle, 10-14 p in length ; conidia not observed. 
Host: Collinsia bartsiaefolia , Calif, (type).

iThis was first described by Davis in Trans. Wise. Acad. Sci., Arts, Lett.,
