bubalinovelatus M.M.Moser & Ammirati (1999) Phlegmacium subfoetidum is a species of mushroom producing fungus in the family Cortinariaceae.

It was described as new to science in 1944 by American mycologist Alexander H. Smith who classified it as Cortinarius subfoetidus.

In 1999 Meinhard Michael Moser and Joe Ammirati published the variety Cortinarius subfoetidus var.

[3] In 2022 the species was transferred from Cortinarius and reclassified as Phlegmacium subfoetidum based on genomic data.

[4] The mushroom cap is 3–10 cm wide, convex to flat (sometime umbonate), lavender to pinkish, bluish in age, slimy, smooth, with a fruity odor.
