Discalis is a genus of extinct vascular plants of the Early Devonian (Pragian or Siegenian stage, around 411 to 408 million years ago). The name is derived from the Greek δίσκος, referring to the disc-shaped sporangia (spore-forming organs). The genus was first described by Hao in 1989 based on fossil specimens from the Posongchong Formation, Wenshan district, Yunnan, China.
