Pleurotus eryngii var. thapsiae var. Nov. from Sicily

Abstract

Field investigations in the Sicilian territory allowed the study of Pleurotus eryngii basidiomata growing in association with Thapsia garganica. The evaluation of morphological, ecological, distribution, and isozyme and PCR-RAPD data together with a revision of Bresadola's herbarium specimens kept in the Herbarium Botanische Staatssammlung (M) led to the description of a new variety, Pleurotus eryngii var. thapsiae var. nov.
