Intraspecific variability in Peniophora aurantiaca (Basidiomycetes)

Nicolas Küffer, Nils Hallenberg

Open publisher page 4 citations

Abstract

Intraspecific, genetic variation was studied in Peniophora aurantiaca using the internal transcribed spacer regions of the nuclear ribosomal RNA region (ITS). Specimens originating from Canada, Greenland and Switzerland were compared. The ITS sequence data were similar with only 11 phylogenetically informative characters, but an allopatric differentiation was obvious. Overall variability is high within the North American specimens compared with the Swiss specimens which had almost no variable characters.
