Observation 199568: Tulostoma Pers.

Notes:
My son sent these photos today from Death Valley. Why no species names for Tulostoma on MO? Have they never been defined? Also surprised to see some posts from Pennsylvania.

Why cretaceum?

The sandy habitat and the lacerate mouth. In those I’ve collected the endoperidium is always well pitted by the grains of sand. I wish the entire plant had been excavated. They are often very deeply rooted. In cretaceum there are rather impressive rhizomorphs attached to a volval-like structure (unless that has rotted away). If you find more please post.

There is a key to over 50 species here: http://mycoportal.org/.... Need microscopy to get to species in many cases I think. See also: Kuo, M. (2011, January). Tulostoma lloydii. Retrieved from the MushroomExpert.Com Web site: http://www.mushroomexpert.com/tulostoma_lloydii.html for a description of one of the eastern species.
