Lignosus dimiticus is a species of poroid fungus in the family Polyporaceae found in Zaire. Its fruit body features a funnel-shaped cap up to 10cm (00inches) in diameter and 15abbr=onNaNabbr=on in the centre. The smooth, white stipe has a woody texture, and measures 8abbr=onNaNabbr=on long and 12– thick. Unlike other members of Lignosus, L. dimiticus has a dimitic hyphal system, as it lacks binding hyphae in its trama and context.
