Handkea utriformis (Bull.) Kreisel

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]

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.^[5]
