First records of Rhizopogon rocabrunae and R. pumilionum (Boletales) from Italy

The paper reports a macro- and micromorphological investigation on Rhizopogon rocabrunae, a very rare hypogeous macrofungus, recently collected in Liguria (Italy) in two different times and locations. These specimens represent the first authentic record of this species from Italy. According to our microscopic analyses, an older Italian collection, formerly identified as R. rocabrunae, must be ascribed to R. pumilionum, a species previously never reported from Italy. Notes on closely related species are also provided.
