The vegetative component (or thallus) consists of small scales (technically, squamules) which typically occur in abundance, on bark or wood. Clearly there is a resemblance to Cladonia, another genus of squamulose lichens and one that is very common locally (mostly on soil). In both genera the spore-bearing apothecia are held aloft, but those of Cladonia are markedly coloured. Thysanothecium was first described in 1846 and this was the first description of a lichen genus based on Australian material.
