          Abstract

          The genus Hydnophlebia includes two species of wood-inhabiting fungi, Hydnophlebia chrysorhizon and Hydnophlebia omnivora. Both are characterized by cream to reddish-orange, resupinate basidiome, with hydnoid hymenophore, margin with strands, a monomitic hyphal system, tubular to ventricose cystidia and elliptical spores. In this paper, a taxonomic study of Hydnophlebia, using morphology and molecular analyses of large subunit nuclear ribosomal DNA (LSU) and the internal transcribed spacer nrDNA operon (ITS), is reported. Three new species, Hydnophlebia canariensis, H. gorgonea and H. meloi, from the Macaronesia bioregion (Canary Islands and Cape Verde Archipelago), are described.

            The general stochastic model of nucleotide substitution.

            DNA sequence evolution through nucleotide substitution may be assimilated to a stationary Markov process. The fundamental equations of the general model, with 12 independent substitution parameters, are used to obtain a formula which corrects the effect of multiple and parallel substitutions on the measure of evolutionary divergence between two homologous sequences. We show that only reversible models, with six independent parameters, allow the calculation of the substitution rates. Simulation experiments on DNA sequence evolution through nucleotide substitution call into question the effectiveness of the general model (and of any other more detailed description); nevertheless, the general model results are slightly superior to any of its particular cases.
