[2] Coprinus calyptratus is a small inkcap mushroom with white flesh and a distinctive star shaped veil remnant on the cap.

Starts egg shaped and covered in a veil before expanding to become campanulate which may flatten or curl upwards with age.

[4] This in reference to remnants of the universal veil which remain on the cap as scales which Peck described as calyptra.

[3] It is found on sandy soil which has been disturbed in which the bulbous base of the deep rooting stem may be hidden.

It is slightly smaller than the well known Coprinus comatus and has a star shaped patch of universal veil remnant in the centre of the cap.
