Lanzia lanaripes (Black tacks)

This is a small disc-like fungus with a long stem. It is found throughout southern Australia in both wet and eucalyptt forests and temperate rainforest; often fruiting from cracls or amongst moss on the surface of wet well-decayed wood. The moss covering serves to keep the wood moist between rain events.

Thw whole fruit body is shaped like a small flat-headed nail or tack, hence its common name, Black tacks. Disc-shaped caps are up to 10mm diameter, the upper surface is smooth, bluish black to black, flat or with a small central depression. The lower surface of the disc and stem are lighter in colour, smooth or minutely downy. Stems vary in length up to 20mm long and taper downwards towards the base which may be sparsely hairy or woolly.
