Dictyocephalos is a genus of fungi in the family Phelloriniaceae of the order Agaricales. The genus is monotypic, and contains the single species Dictyocephalos attenuatus, commonly known as the stalked oddball,^[2] which was described by the American botanist Lucien Marcus Underwood in 1901 (as D. curvatus).

Dictyocephalos attenuatus is a unique species of mushroom, as it has a gleba like a puffball, but it also has a stipe and a volva, like an Amanita.^[2][3]
