Original Article


The new species Boletus mendax of sect. Luridi is reported and discussed; its morphological, anatomical and edaphic characters are described and a molecular investigation is carried out in order to elucidate the separation from neighboring taxa. The present research also demonstrates the high degree of segregation of two collections of the recently described Boletus comptus and the low taxonomic value of the usual reddish pigmentation of the subhymenophoral layer (the so called Bataille’s line) for both taxa B. mendax and B. luridus. Colour pictures taken in habitat of the taxa presented herein are also provided. Finally, according to an ITS analysis, sect. Luridi is shown to be polyphyletic and the importance of morphological features as stipe ornamentation, context colour beneath tubes and amyloid reaction in stipe base is discussed.

We sincerely thank all friends and colleagues who have sent us material for our investigation and who have contributed through useful discussions to define the taxa treated in this work, in particular: Ulderico Bonazzi (Regnano, Reggio Emilia, Italy), Giovanni Consiglio (Casalecchio di Reno, Bologna, Italy), Matteo Gelardi (Bracciano, Roma, Italy), Carmine Lavorato (San Demetrio Corone, Cosenza, Italy), Mauro Sarnari (Terni, Italy), Gianfranco Visentin (Boara Polesine, Rovigo, Italy) and Gang Wu (Kunming Institute of Botany, China). We also thank the Curators of the herbaria of the Civic Museum of Venice (MCVE), Giovanni and Maurella Robich (Campalto, Venezia, Italy), and of the Mycological Association Bresadola (AMB), Gianfranco Medardi (Rezzato, Brescia), for availability and patience toward us, and Caroline Hobart (Sheffield) for improving the English text.
