A Chemotaxinomic Study of the Genera Clavulinopsis and Cantharellus

Species of the genera Clavulinopsis and Cantharellus were collected from locations around Southwest Michigan. The pigments of each collection were extracted with 95% ethanol end the visible absorption spectrum of each was recorded on a DB recording spectrophotometer in the range of 300-800nm. The remainder of each collection was dried end put in the herbarium of Dr. Paul Olexia at Kalamazoo College. Separation of the initial pigment extracts was attempted by the use of thin-layer, paper, and column chromatography. Where separation of the extracts occurred, however, the fractions obtained had about the same visible absorption spectra. The visible absorption spectra of the initial pigment extracts for the species studied seemed to sort into groups which fell along existing taxonomic divisions, and therefore, indicated that these taxonomic divisions might be natural and represent divergent evolutionary lines.
