Polyploid evolution and plastid DNA variation in the Dactylorhiza incarnata/maculata complex (Orchidaceae) in Scandinavia.

abstract：:Serpula himantioides (Boletales, Basidiomycota) produces thin resupinate basidiocarps on dead coniferous wood worldwide and causes damage in buildings as well. In this study, we present evidence for the existence of at least three phylogenetically defined cryptic species (referred to as Sib I-III) within the morphospe...
