This species occurred abundantly in a single locality near New 
Haven, but lias not been found elsewhere in this country. Specimens 
from Brazil, however, which seem to be identical with the Connecticut 
form, have since been received from Dr. Otto Pazschke. Since the 
writer’s original spelling* of the specific name (hypoxys) has been set 
aside in favor of hypoxydis by Saccardo and others who have had occa¬ 
sion to mention it, some pains have been taken to ascertain from class¬ 
ical authorities, both at New Haven and at Cambridge, exactly what the 
spelling of such a genitive should be. Although the authorities in ques¬ 
tion were unanimous in asserting that liypoxydis (or hypoxidis) was abso¬ 
lutely incorrect' the unanimity in regard to what spelling is really cor¬ 
rect was not so striking. The general opinion seems to prevail, how¬ 
ever, that such a genitive, had it been used, would have had the termi¬ 
nation yiSj and hypoxyis may therefore be safely employed to designate 
the present form.

Mycelial liyplue branched, rarely penetrating the cells of the host by irregular 
haustoria. Conidiopliores slightly swollen at their point of exit through the stomata, 
arising singly or two to several in a cluster; simple or once dichotoiuously branched, 
and once to several times successively inllated below their apices. Conidia oval or 
elliptical, with truncate base and papillate apex; 35-50 by 20-24//. Germination by 
zoospores, usually fifteen in number, or rarely by a simple liypha of germination. 
Oospores unknown. On pods, stems, and leaves of the Lima bean (Phaseolus liinatus). 
Sept, and Oct., New Haven, Conn., 
Although so common about New Haven this species has not, so far 
as the writer is aware, been observed in any other locality. Whether 
it is an introduced exotic or is a native form which may yet be found 
on some native leguminous plant, is uncertain; yet its introduction at 
New Haven may possibly be traced to the fact that a gentleman resi¬ 
dent there, in whose garden the fungus was abundant, received a 
package of Lima beans directly from South America some years since, 
which, when planted, may have originated the epidemic which all the 
gardeners whom the writer questioned concerning it, agreed to be of 
comparatively recent origin. The species is mentioned by Fischer in 
his Phycomycetes (Eabh. Kryptogamenfl . Yol. i. part 4, p. 415) as an 
“ungenau bekannte Art;” why “ungenau” is hardly evident from the 
references above quoted.
