Recognized by sight: While Scleroderma literally means thick skin, not all species are all that thick. However, Scleroderma differs from Rhizopogon in that it usually has a thicker basal attachment of rhizimes, and generally lacks overall rhizomorphs, especially near the top. Generall Rhizopogon is hypogeous or slightly epigeous; Scleroderma is nearly exclusively epigeous as shown. The slightly enlarged sterile base composed mostly of thickened rhizomorphs, plus the gleba having a fibrous texture (never present in Rhizopogon) suggests something near Scleroderma areolatum to me.

After found those specimens of Rhizopogon last year I never encountered them again. In the meantime I have collected some Scleroderma. This time I was convinced that was a Rhizopogon again, mainly because they were not so thick as Scleroderma. As you can see by the photos the specimens were already a bit too mature and thus I didn’t collect any material. But now after read your proposal I think that you are right. Glad to learn with you again.
