Tipularia discolor is an orchid with a reddish brown stem and dull yellow to purplish brown weakly monosymmetric flowers. [10] The leaves of the orchid are easily distinguished as they are ovate with a bright green adaxial surface (top) and a purple abaxial surface (bottom). In autumn, a single leaf emerges, which lasts throughout the winter. [11]
The English name 'common spotted' refers to the species' abundance and the spots on its leaves. The French and German common names also honour Leonhart Fuchs.

Black rot on orchids is caused by Pythium and Phytophthora species. [1] Black rot targets a variety of orchids but Cattleya orchids are especially susceptible. [1] Pythium ultimum and Phytophthora cactorum are known to cause black rot in orchids. [1] Pythium ultimum is a pathogen that causes damping-off and root rot on plants. [2]

These cylindrical leaves act as a water reserve. They have long racemes with yellow flowers that seem to fan out at the top. Sizes of these orchids can vary from miniature plants of a couple of centimetres to giants with 30 cm-long leaves and racemes of more than one metre long. These species, known as the Mule-Ears, are now classed as Psychopsis.
These caespitose orchids grow in tufts from a short rhizome, with a dense pack of stems. They lack pseudobulbs. On each stem grows one large, thin, plicate leaf with a sharply defined midrib. These glabrous, light to dark green leaves may be spongy, taking over the function of the missing pseudobulb. They are tipped with a mucro (a short tip).
