Updates on Protubera (Protophallaceae, Phallales) and additional notes on P. maracuja

•We update the genus Protubera compiling all the literature available for this genus, plus morphological, ecological and molecular data.•We were able to see specimens in the field, which contributed to the ecological knowledge of some species.•We separated which species should be treated in the family Protophallaceae and commented about the species that should be excluded.•We present color photos of Protubera maracuja, a neotropical species.

Since the genus Protubera was erected in 1895 by Alfred Möller, fourteen species have been described in the genus, from tropical, subtropical and temperate regions of the globe. Based on morphological, ecological and molecular data, we concluded that only six species (P. borealis, P. jamaicensis, P. maracuja, P. nipponica, P. parvispora and P. sabulonensis) should be accepted in Protophallaceae. In this article we present an update of the genus from a morphological and phylogenetic perspective, including comments on the excluded and doubtful taxa, and a key for the accepted species. Additional morphological and ecological notes of P. maracuja, especially regarding features of peridium and substrata, as well as color photos, are presented.
