Description
  • Cap: Bright orangish red, the cap (pileus) of C. cinnabarinus is generally about 2 to 18mm in diameter and is convex, shell or fan shaped with a finely down felted surface when fresh, especially at its base, becoming minutely pitted or more or less bald and dry. The margin is irregular to fibrous and initially inrolled. [5][4]
  • Stipe (stem): Absent, but a pale, lateral pseudostem is sometimes present.[5]
  • Gills: Coloured pale brown with a red-orange edge, are crowded and adnexed.[4]
  • Spores: The spore print is buff. Spore shape is broadly elliptical to subspherical with a finely spiny to warty surface, measuring 8-8.5–8.5

× 5.5–6/5 µm in size.[4]
