They are arranged in cylindrical cuffs about 10 IX in size and in glomeruli. As a matter of fact the spores are readily isolated from one another. They arise one by one in variable numbers along the mycelium, but as a rule in very large quantity in each segment of the thallus. There is no apparent order in their arrangement. So long as it reniains on the filament the spore appears pear-shaped. It is attached by a very fine sterigma, from 1—2 /i in length and about n in width. When shed^ the spore is oval. Its dimensions vary from 3-5-6 ix in length and from 2-3—411 in breadth. The form, the distribution and the brown color of the spores and their fructification in the form of cylindrical cuffs, ar- ranged in branches at the extremities of the filaments, constitute.

Slant culture on glucose agar, eight days old (Hektoen and Perkins, in "Jour, of Exper. ;). together with the original substratum of the fungus, a group of characters which differentiates Sporotrichum beurmanni sharply from all other sporotrichs (Matruchat). Hektoen and Perkins thus describe Sporotrichum schenckii: The threads of the mycelium are seen to be doubly contoured; the proto- plasm is somewhat granular and interrupted at fairly regular inter- vals by transverse septa; the diameter of the threads varies some- what, the average being about 2 n; the branches are not frequent and do not bear any fixed relations to the septa. In the hanging-drop cultures the relations of the conidia to the mycelium are very nicely shown. The spore-bearing branches which grow out in a radiating manner from the central f
