The fruit bodies are mainly plasmodiocarps, which are worm to net-shaped, beige, ochre or yellow to red-brown coloured and red spotted.
The strands are occasionally so closely bound together that they produce pseudo-aethaliae, rarely cushion-form fruit bodies, which have a diameter from 0.3 to 0.5 mm (0.012 to 0.020 in) and expand over several centimetres wide.
[1] The capillitium comprises a few rotund chalk knots, which are linked through transparent to yellowish strings with acanthoid, non-overgrown humps.
The capillitium becomes segmented through white to yellowish, partly perforated limestone plates, which are overgrown on the edge of the peridium.
The spores are 8 to 10, rarely 7 to 11 μm and their body is black-brown, in transmitted light purple-brown, on the surface dense and fine-warty.
