Clavulina cristata is a mycorrhizal coral fungus occurs world-wide in various forest environments. Fruit bodies up to 80 mm high, branching tips frilled to variously toothed, shining white, discolouring yellowish with age. The extent of branching is very variable, and there are other complications in the identification of this species. It is subject to attack by a pyrenomycete (a microfungus), Helminthosphaeria clavariarum, which causes disolouration from the base upwards into shades of grey to black. This causes confusion with two other fungi, namely Clavulina rugosa and Clavulina cinerea, both of which can be greyish and sometimes develop toothed (cristate) points. There may well be a complex of species of similar appearance. It may be simplest to just name white, pointy corals as the Clavulina cristata group. Eco Tourism track, Sanatorium Picnic Ground, Mt Macedon, 2010.
