It occurs as yellow clusters of slender prisms or needles. It crystallizes in the orthorhombic system.
The carpholite group includes ferrocarpholite, magnesiocarpholite, vanadiocarpholite, and potassiccarpholite.
==Discovery and occurrence== It was first described in 1817 for an occurrence in Horní Slavkov (Schlaggenwald), Karlovy Vary Region, Bohemia. The name derives from Greek ''karfos'' for "straw" and ''lithos'' for "stone" due to its crystal habit.<ref name=Webmin/>
Its typical occurrence is in shales that have undergone low grade metamorphism. Associated minerals include sudoite, manganoan garnet, chloritoid and fluorite.<ref name=HBM/>
