The disease is said to be more common in men than women, and occursin young adults or in those of middle age. Pathology and Anatomy.—As its name implies, the microsporonminutissimum (Fig. 287) is the smallest in the group of vegetable power of six hundred diameters is required, when the following character-istic features may be observed : The growth is composed of fine threads ofmycelia, which are jointed, although they are not branched, the segmentsbeing of very unequal length and in thickness not exceeding mm. Themycelia are neither straight nor markedly curved, but are tortuous and often. Fig. 287.—Microsporon minutissimum (No. 12 immersion) (Corlett). form a very fine network. Conidia have not been found, although the field isthickly studded with granular material. According to Payne,1 the myceliaare situated between the epidermic scales and near their free margin. Someof the threads have a beaded appearance resembling spores, with doubtfulgroups of granules scattered over the field. Weyl2 found the mycelia of exceedingly variable length, twisted in wavylines, and always narrow and pale. Numerous small bacteria and zoogleawere also present. The diagnosis can offer no difficulty if the special characters of the dis-ease are borne in mind ; it chiefly lies between eczema marginatum, tineacircinata, and tinea versicolor. The microscope will readily enable one todifferentiate between them. The prognosis is favorable, and the treatment of the affection is thesame as that given in tinea
