In the center of the lesion are doubly contoured oval or rectangular conidia, 3. Pig. 100.—Typical scutulum of favus in a mouse. (After Plaut.) to Sjn by 3 to 4n, single and in chains. The mycelial threads are indistinguishable in the center, but are seen at the periphery as tubes of very irregular width, refractive with granular proto- plasm, often branched or knobbed at the end. The scutulum in its interior is a pure culture of the mold, entirely free from other organisms. The mold also grows in the interior of the hair shaft, and by macerating the hair in alkali the fungus may be demon- strated microscopically. Cultures may be obtained upon various media. Plaut recom- mends a medium containing pepton i to 2 per cent, glycerin.
