MUCOR MUCEDO. 231 



Division II. Trichosporei (Leveille). 



There are no species of fungi found on man belonging to this 

 division. 



Division III. Cryptosporei (Leveille). 



Receptacula floccosa, sept at a, simplicia aut ramosa. Sporidia 

 continua, in sporangia terminally membranaceo, columella centrali 

 munita vel non inclusa. 



Tribe Columettati : Sporangium vesiculosum, subtus irregu- 

 lariter aut in orbem dehiscens. 



XIII. Mucor mucedo. Tab. V, fig. 5. 



Genus Mucor (Micheli) : Flood tubulosi, subseptati, fertiles, 

 erectij apice aquales, terminati peridio (sporangia] membranaceo, 

 dehiscente (raro diffluente), includente sporidia discreta. 



Species Mucor mucedo, L. ( = Mucedo ; Mucor vulgaris, Mucor 

 splicer ocephalus, Mucor tenuis) : Byssinus floccis fertilibus sim- 

 plicibus, peridiolis (sporangiis) sporidiisque globosis, demum ni- 

 grescentibus. 



Baum, Litzmann, and Eichstadt found this parasite in a 

 cavity, in a case of inflammation of the lungs. It formed 

 a black mass of filaments, interspersed with round globules, 

 adhering to the walls of the cavern. Each filament had a 

 process on the outer surface of the mass, terminating in an 

 enlargement, surrounded by a row of oval cells. Sluyter views 

 these formations as Mucor mucedo, adhering to Schoener's theory. 

 The very imperfect illustrations would rather show it to be an 

 Aspergillus, as .Robin observed. 



Robin leaves undecided whether the parasites found by Degner 

 and Horn, in a case of gangrcena senilis, and which the latter 

 believes he has discovered likewise on certain purulent spots and 

 blistered surfaces exposed to the air, belong to this division or not. 



On looking at the illustrations, I am unable to find sufficient 

 distinction from the species of Aspergillus described under X.
