Historical bolete illustrations added
I started adding original illustrations that were associated with the first descriptions of different boletes. Some of them are already available for Boletus appendiculatus, Boletus edulis, Boletus luridus, Boletus regius, Chalciporus piperatus, Gyroporus cyanescens, Leccinum aurantiacum, Rubinoboletus rubinus and Tylopilus felleus.
