Henningsomyces candidus

The fruit body is a white tube, growing to a length of a millimetre or so and with a diameter up to a third of a millimetre or so. The fruit bodies grow on the underside of dead wood, so that the tube mouths face downward. The individual fruit bodies are small but usually they grow in large groups and may be spread over several square centimetres. The outer surface of each tube is covered with short hairs and a microscope shows those hairs to be smooth and branched at their apices.

 Rectipilus fasciculatus, also found in the ACT, is similar macroscopically but with smooth hairs that, though they may be a tortuous, are not branched. The fruit bodies of both species are initially more or less globose, but definitely elongated at maturity. Other species, in several genera, produce somewhat similar but markedly squatter fruit bodies.
