Fig. 132. Mycotic lesions on the foreflipper of a Pacific walrus (upper). In this instance, 

 the major lesions were on the tips of the digits (arrows); another small lesion can be seen 

 on the dorsal surface. The presence of mycelia and spores of the fungal agent was 

 demonstrated in the stratum corneum of one of the lesions (lower) treated with Gomori's 

 stain. (Photos by F. H. Fay)
