The systematic position, variability and distribution of the two species of Rhachomyces parasitic on Italian Duvalius are defined on the basis of several new findings. Rhachomyces stipitatus Thaxter was found in Liguria, central Italy, Sicily and Sardinia; its synonymy with R. capucinus Thaxter is confirmed and the ssp. pallidus Maire is considered of no systematic relevance. R. maublancii, whose position is regularized by a Latin validating diagnosis, was only found on the Alps and previous records in other countries are questioned.
