Chromatographic separation of pigments produced by Arthroderma benhamiae.

Variations in pigment production under different cultural conditions have limited the usefulness of pigmentation for identifying strains of Arthroderma benhamiae. If culture conditions are constant, pigmentation by individual strains is reproducible, and may be extracted and separated by thin layer chromatography. This allows recognition of pigment similarities which may be masked in whole colonies, thereby greatly enhancing the value of pigmentation in strain identification.
