An epiphytic species of Jania (Corallinaceae: Rhodophyta) endemic to southern Australia

Abstract

Mostly on the basis of conceptacular features, the name Jania pusilla (Sonder) Yendo is confirmed for a species also known as Corallina nana Harvey or Corallina lenormandiana De Toni. J. pusilla is a short plant with a crustose base; it has broad intergenicula, large conceptacle chambers, and the largest tetrasporangia known for articulated corallines. These plants are endemic to southern Australia where they occur on certain species of Cystophora.
