“…Pigment production is dependent on genetic and environmental factors, especially nutrient content of the growth medium (Silva, 1953). These variations on pigment production limit the usefulness of visual observation of thallus pigmentation as a taxonomic criterion.…”

“…Although the dermatophytes are common fungal pathogens, very little is known concerning their metabolic systems. Biochemical studies with this group have been limited primarily to the nutritional requirements (Robbins et al, 1942;Schopfer and Blumer, 1943;Robbins and Ma, 1945;Georg, 1950;Benham, 1953;Silva, 1953;and Silva and Benham, 1954) and the demonstration of various extracellular enzymes (Tate, 1929). Respiration studies were first conducted by Nickerson and Chadwick (1946) in which the effects of substrate and pH upon oxygen uptake were determined.…”

Replicates of whole colonies of four species of closely related dermatophytes were analyzed by pyrolysis gas-liquid chromatography (PGLC). The four species included fifteen strains of Arthroderma tuberculatum, and two strains each of A. benhamiae, Nannizzia gypsea and N. incurvata. Individual peaks on different pyrograms were identified as homologous with the aid of internal markers by the superimposition of pyrograms. The peak height data extracted from the pyrograms of the fungal samples were analyzed to compute average similarities between pairs of pyograms. The average was calculated with each peak weighted equally, and log weighted for its information content. The results of the cluster analyses of proximities were generally similar. Most, but not all, replicates of each strain were similar enough to be clustered together. Some strains belonging to the same species were also similar enough to be grouped in one cluster. Other strains of a single species varied sufficiently to be put in separate clusters. The nearest neighbour to each OTU (pyrogram) was always a replicate of the same strain.
