L. cruciatus

Pegler, Læssøe and Spooner mention 5 species worldwide. Dring keys all 5 species with descriptions. Even with a blurry picture it keys to either L. gardneri or L. cruciatus. The red or pink color is variable and not a taxonomic character.
L. gardneri is a south-east Asiatic species, India and Africa. (NOT verified from North America)
L. cruciatus is found in Europe, Africa, Australia, South America and North America.

Agree Lysurus. Why L. cruciatus?

The books I have don’t do a good job of separating the species. Given how blurry the image is I’m just curious how you got to species with this one. Most of the pictures I found of L. cruciatus are still covered with spore slime so the heads are dark and not old enough to show the pink under color.

Lysurus cruciatus has a round stem and the reddish columns contain the spores. Lysurus gardneri is very similar in appearance and is from Asia and Africa. It has a sterile base at the bottom of the reddish arms.
