[1] It was isolated from 8 immigrants from Jamaica, Nigeria, and Sierra Leone who had shown signs of tinea pedis and skin infections.

Conidiophores are unusually small (micronematous), can be branched or unbranched, pale or colorless, straight, smooth, and irregular.

Conidia are arthrosporic, simple, cylindrical to ellipsoid or rounded, sometimes rough, catenulate, separating, hyaline or pale, with thin cell walls.

[5] Scytalidium hyalinum is able to hydrolyse gelatin, casein, tyrosine, olive oil, and urea.

[7] It is also present in the UK,[1] Spain,[6] Italy,[8] Australia,[9] and France[10] via travel and immigration.

Until 2007, when it was recovered from soil in Indian rat burrows in India, S. hyalinum had never been isolated from the environment.

It can cause distinctive thickening, lichenification, and discoloration of the knuckles and sides of fingers, but it is not consistent.

[13] Scytalidium hyalinum and N. dimidiatum share a very similar antigenic structure distinct from other pathogenic fungi.
