of certain other species of fungi is questionable. A descrip-

species. 
PHYCOMYCETES 
MUCOR 
M. cornealis Saec. in Cavara, Centralbl. f. Bakt. I. 72:23-37. 
1914. 
This fungus was isolated by Cavara ('14) from a man's 
eye which had been struck by a piece of dirt. A week after 
the accident, there developed a ceratomycosis mucorinea, an 
inflammation of the cornea. А culture of the fungus was 
sent to Saccardo for determination, who found that it was a 
new (?) species closely related to Mucor racemosus and M. 
Regniert. It produced injurious effects when inoculated into 
the blood system of rabbits and guinea-pigs, with the occur- 
rence of lesions in the kidneys. Saceardo’s description of 
this fungus agrees entirely with the descriptions for M. 
corymbifer, including the color of mycelium, the maximum 
and minimum growth temperatures, and the type and size of 
sporangia, columella, and spores. 
M. corymbifer Cohn, in Schroeter, Kryptogamenflora 
Schlesien 3:205. 1886. 
Mycelium at first snow-white, later a dull gray, hyphae 
penetrating the substratum or aérial and ascending, hyaline; 
hyphae of sporangia racemose, bearing 1-12 sporangia; spo- 
rangia pyriform, varying in size from the smallest, 10-20и, 
to the largest, 704 in diameter; columella conical to hem- 
ispherical, finally papillate, brown; spores hyaline, elliptical, 
3 X ди, to ovoid, 4 X Dän, 
This species was first isolated by Lichtheim (’82) in his 
laboratory, growing with Rhizopus Cohnii on a decoction of 
bread. It was reported by Paltauf (’85) as occurring in 
the principal organs of a man dead from generalized mycosis; 
by Huckel in 1885, and Siebenmann in 1889, as associated 
with Aspergillus fumigatus in the external auditory canal; 
also in two cases of pulmonary mycosis, by Fürbringer (’76). 
It has an injurious action on rabbits and guinea-pigs, accord-
