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] The genus name of Handkea is in honour of Horst-Herbert Handke (1913-2005), who was a German botanist and Professor at the University of Halle.

[5] Phylogenetic analyses published in 2008 shows that Handkea may be grouped in a clade along with species from several other genera, including Lycoperdon, Vascellum, Morganella, Bovistella, and Calvatia.
