ing to Lichtheim (’82), and Berthelat (’03). This species is 
considered by Lucet and Costantin, (’01) as including sev- 
eral varieties known as M. ramosus Lindt, M. Truchisi Lucet 
& Cost. and M. Regniert L. & С. 
M. Mucedo L. Sp. Pl. 2:1655. 1764. 
Mucor Mucedo is found, in general, on all organic sub- 
stances of vegetable and animal origin in the process of de- 
composition, and more particularly on the excrement of ani- 
mals, It is extremely common in the state of a saprophyte, 
and has been reported at various times as occurring on man 
and other animals; in mycosis of man by Hiller in 1874 
(cited by Plaut, '03) and Fürbringer (776). In these observa- 
tions the determination of the fungus was not sufficiently 
established, and the demonstrated virulence on animals was 
possibly due to impure cultures, since Berthelat (203) finds 
that it is without action on rabbits and guinea-pigs.

This fungus was isolated from an epidermal lesion on a 
horse affected with Oospora (Trichophyton), and according 
to Costantin (’01), was non-pathogenic for rabbits. This or- 
ganism evidently had nothing to do with the diseased tissue 
from which it was obtained. Costantin later regarded this 
fungus as identical with, or as a variety of, M. corymbifer. 
M. Truchisi Lucet & Cost. Archiv. d. Par. 4:366-384. 1901. 
A culture of this species of Mucor, obtained by Lucet (201) 
from an epidermal lesion on a horse affected with Oospora 
(Trichophyton) minimum, was toxic for rabbits. It is possi- 
ble that this fungus played no part in the observed affection, 
and more recent studies of this organism led Costantin to 
consider it as identical with M. corymbifer.

This species was observed by Lucet and Costantin (’00) in 
a woman affected with pseudo-pulmonary tuberculosis. Cul-
