Phallus rubicundus/rugulosus (Bosc) Fries/(E. Fisher) Lloyd    Synonyms: Phallus rubicundus, Phallus rugulosus, Wrinkly Stinkhorn.
Kingdom Fungi   >   Phylum Basidiomycota   >   Class Agaricomycetes   >   Order Phallales   >   Family Phallaceae   >   Genus Phallus   

Status:

It appears Maryland is in an overlap zone between these two species and there are some rough macro characteristics separating the two

Description:

Fruiting body: arises from egg-like structure. In maturity consists of hollow, reddish-orange, pock-marked stalk topped by narrow, bell-shaped cap with skirt at bottom and reddish opening at apex. Cap covered with foul-smelling, green spore mass (J. Solem, pers. comm.). According to Kuo, "Phallus rubicundus has a red to pink stem that is, on average, somewhat thicker than the skinny, orange stem of Phallus rugulosus. In North America the two species also have different ranges; Phallus rubicundus generally stays south of a line between roughly Oklahoma and Virginia, while Phallus rugulosus is more common from roughly the same line northward, although there Is some overlap."

Where to find:

Found solitary or in clusters on or near gardens, wood chips, and meadows.

There are 40 records in the project database.
