According to Simon & Schuster’s guide to Mushrooms, the Dog Stinkhorn arises from a white or pale yellow “egg” and is covered by a fetid slime. Mmmmm. Not surprisingly the edibility is listed as “of no interest”. Elsewhere I read that the slime attracts flies which pick up the mushroom’s spores and deposit them elsewhere helping to spread this one around. I found two in my side bed, one next to a small rhubarb and one near the highbush cranberry. These are about the size of your pinky in length and diameter but some text says they can get several times that size. Strange critter indeed.
