Prof. \V. G. Farlow has examined this and considers it only the 
spores of Sordaria, or , some related genus. He has recently submitted 
specimens to De Bary, who agrees with him in saying that the spots 
have no connection whatever with the leaf, but are the spores, in all 
probability, of a Sordaria, (^haetomium, or some related ascomycetous 
fungus. E. VV. I). JI. 
A NEW IOWA AECIDIUM. 
One of the most conspicuous of all aecidual forms was found last 
summer, growing in abundance on the lopseed {Phryma leptostackya)^ at 
Spirit Lake, Iowa. Specimens were submitted to Dr. Farlow, who found 
no record of an aecidium upon Phyma. In view of this fact, the follow¬ 
ing may be given as a description of this mcidium, being fully aware 
that it is only a form of some species, known or otherwise, and that a 
provisional name is a convenient handle until the true one is found : 
Aecidium Phryma, nov. sp.— Ilypophyllous; spots elfused, con¬ 
spicuous, orange-yellow, not thickened, 1—3 cm. broad; secidia usually 
in rows along sides of leaf veins, sometimes in evident circles, prominent, 
borders not greatly recurved; spores 20—25 y in diameter, globose, 
epispore thin, nearly smooth ; spermogonia indistinct. On Phi'yma 
leptostchya^ Spirit Lake, Iowa, July, 1885. B. D. IIalsted.

UNCINULA POLYCHAETA, B. & C. 
Uncinula poly^cheta, H. & C. Grev. IV, p. 159. 
J'he description of this species in Grevillea is very brief, and is as 
follows : 
PEiiiTnECiis sPAiiSTS ; appendicibus multis. On leaves of 
(Jeltis occidentalis. Car. No. 5619. 
Perithecia scattered *, appendages .about 28, U times longer than the 
diameter of the perithecia, hyaline.” 
Prof. Spegazzini in his Fungi Argentini, Pug. 2, p. 17, describes, un¬ 
der the name of Uncinula LyncMi, an Uncinula^ found on leaves of 
Celtis Tala, near Buenos Ayres, which, on page 44 of the same work, is 
said to be identical with U. polychmta, B. & C., and is taken as the type 
of a new genus, Pleocliceta, S. <St S. Two forms are mentioned: in the 
lirst of which the perithecia are densely gregarious and partially im
