Fomitopsis lilacinogilva, commonly known as the lilac shelf fungus, is a species of polypore fungus in the family Fomitopsidaceae. First described in 1839 by Miles Joseph Berkeley as Polyporus lilacinogilvus, it was shuffled to several genera before being placed in Fomitopsis in 1975.
The fungus produces shelf-like fruit bodies, usually 3–10 cm (1–4 in) in diameter, attached directly to the substrate without a stipe. The caps have concentrically ridged surfaces, and are brown with lilac tints. The lilac-coloured surface of the cap underside has 4–5 pores per millimetre. The spore print is white; spores are smooth, ellipsoid, and measure 6–9 by 2–3 µm. Fomitopsis lilacinogilva is found in Australia, where it grows on fallen logs of Eucalyptus trees, causing a brown rot.
