Comments: In Germany Phellodon niger has already disappeared from many historically known locations in and around industrial regions (Ref.:2.). The causes are acid precipitations, other airborne toxins and eutrophication of forest ground. The species is worldwide distributed but rarely common. It is generally in sharp decline and much endangered in Europe (Ref.:2).

About 20 pilei growing solitary and in groups of several partly confluent fruit bodies; pilei diameter 5 – 8.5 cm, spines are dense and from 2 to max 3 mm long; stipe is not well defined, interwoven with surrounding organic ground debris, about 1-2 cm in diameter and 1.5 cm long, tapering toward the base, looking like a thick root; flesh corky-woody, charcoal black; SP whitish-beige, oac851.
