Brief Description:

See generally Voitk, et. al.13 for descriptions of Polyozellus multiplex sensu stricto, the species complex, and the newly described species within the complex.
Following is an old description, and therefore of the complex:
“[caps]: up to 15 cm across, fleshy, dark purple to deep blue black; … slightly roughened and dry, often occurring in clusters above stems that are frequently fused;
hymenium of shallow forked veins often extending down the stems, dark violet black to blue purple when fresh, becoming a paler gray violet when dried;
flesh tough and somewhat brittle, dark purple;
odor faintly pungent,
taste mild and not distinctive when raw.
Spore print white.
Under the microscope, basidiospores ornamented with low bumps, colorless, 4.5 to 9 × 4.5 to 8 μm;
[chemical]: tissues turn greenish black in potassium hydroxide; clamp connections present.”8 (formatting added)
