Corticolous on dying rawirinui (Kunzea robusta). Thallus 10-30 mm diameter, erupting through bark as black, porous, flattened discs - inner thallus appearing carbonised, and what I assume are spores, appear from pores as soot when specimen handled. Resembles Daldinia except flat. Voucher. P.J. de Lange 12980, UNITEC 8064.
