Boletus L.
Recent molecular studies have shown that Boletus in its current circumscription is likely an artificial grouping and it is possible that it will be split at some point into smaller genera. Note that Boletus impolitus and Boletus depilatus for practical reasons are retained here, although there is strong evidence that they are closely related to Xerocomus subtomentosus and its allies.
Fruitbody large to medium sized, boletoid, without veil and ring. Stipe solid, with surface usually covered with granules or network. Flesh variously coloured, changing or not when exposed to air. Tubes easily separable from each other, not tearing apart. Pores usually small and rounded.
Boletus adonis Pöder & Ladurner
Description
Unknown to me. Very similar to Boletus spretus, but distinguished on account of its wider, broadly ellipsoid spores and the amyloid hyphae of the flesh in the stipe base.
Habitat. Broadleaf forests with holm oak (Quercus ilex) and black pine (Pinus nigra).
Distribution. Not yet understood, but apparently a southern/mediterranean species. Known so far only from Croatia and Italy.
Photographs
There are no identifiable photographs available to me or featured on the internet. Colour photographs and black & white illustrations are published in Pöder & Ladurner (2002) and Muñoz (2005).
