Tubercle rind is here taken as outer mantle layer; tubercle vinaceous or of a light to darker brown, older tubercles brown-black to black with blotches of greyish bloom; inner mantle layer with labyrinthine pattern; rhizomorphs with a central core of thick hyphae; rind of tubercle (10-)25(-60) um thick; autofluorescence with UV-filter of the surface of the fresh, mature tubercles deeply velvety black and the interior is moderately bright pink to rose; in KOH hyphae turning along tears from brown to green, inner light coloured parts turned a light pink. |
