Myxomycete with the ability to accumulate heavy metals. Diderma fallax

Abstract

Diagnostic features. Sporangia pale and usually sessile; easy to distinguish in field from other nivicolous species of Diderma, because polygonal scales on the peridium (which can be very dark brown when calcium is lacking) make sporocarps resemble golf balls; microscopically, D. fallax has unusually large, dark and markedly spiny spores.
