Handkea

Handkea is a genus of puffball mushrooms in the family Agaricaceae. In 1989, German mycologist Hanns Kreisel described the genus Handkea to include species of Calvatia with distinct microscopic features, including a unique type of capillitium (coarse thick-walled hyphae in the gleba), with curvy slits instead of the usual pores.[1] Although accepted by some authors,[2] the genus concept has been rejected by others.[3][4]
