ON THE UREDINEAA PARASITIC ON THE JAPANESE GRAMINEAE. 239 
Hokkaido. — I’rov. Ishikari: Horomui (I. July 9, 189b. J. Kasaiiara; I. July 20, 1900. G. 
Tamada). 
Distrib. Europe, America and Japan. 
REMARKS. The teleutostage of this fungus is found on Agropyrum 
glaucum, A.junceum and A. occidentalis in Europe and America ; but it is 
not yet collected in our country. The aecidial stage is commonly found in 
different places of our country. 
DlETEL (3) after examining the Japanese specimens identified them as 
the Atcidium stage of Puccinia Agropyri. I have also carefully compared 
our Atcidium with American specimens of SEcidium Clematidis, and have 
noticed no differences between them. 
DIORCHIDIUM Kalchb. 
1. Diorchidium levigatum Syd. et Butl., in Ann. Mycol., 5, 1907, 
(500).— (PL XII. Fig. 7). 
Uredosori, amphigenous, mostly epiphyllous ; minute, oblong or round- 
ish, on the brownish or blackish discolored spots, scattered or gregarious, 
rarely confluent, loosely covered by epidermis or naked, pulverulent, some- 
what pulvinate, dark yellowish-brown. Uredospores, broadly ellipsoidal, 
subglobose or globose, densely echinulate (distances between spines about 
2~3 i «), 24-30x18-25//; epispore brownish yellow, 2-3//. thick; germ-pores 
2, equatorial, inconspicuous ; paraphyses absent in the sori. 
Hab. On Oplismenus compositus Beauv. 
Loochoo. — Shuri (II. & III. Nov. 27, 1898. N. Hiratsuka). 
Formosa. — Daihoku (II. Nov. 17, 1906. T. Kawakami & R. Suzuki). 
Distrib. India an 4 Japan. 
REMARKS. The species belonging to this genus are generally found in 
the tropical or subtropical regions of Asia, Africa and America. The total 
number of the species is not abundant. 
In Japan, the presence of the species of this interesting genus have 
remained unknown up to this time. We have in our University Herbarium, 
two specimens of the present species collected in Formosa and Loochoo on 
Oplismenus compositus. Our species coincides exactly to the description 
■of the fungus by Sydow and Butler (2) in the characters of teleutospores.
