I can find no, all white stinkhorn in any of my references.

According to the book I have, "Mushrooms", by Gary Lincoff and Thomas
Laesse (ISBN 0789432862) on p.247 it says that the Shameless Stinkhorn
(Phallus impudicus) has a white cap under its olive-green slime. Maybe
rain has washed off the slime on the cap.
