The morphological and physiological features that can be useful in differentiation of T. onychocola from closely related
geophilic dermatophytes or other phenotypically similar dermatophytes are summarized in Table 2. Here we only summarize our observations or mention some features that are not included in Table 2. All species included in differential diagnosis are heterothallic with exception of homothallic A. ciferrii (T. georgiae) and clonal T. rubrum [33–35].
