Not Scleroderma.

Admirable thought, but definately not Scleroderma. Mature Scleroderma will have white or orange veination within the gleba, even when grossly immature. This has none. I think C. gigantea a very good fit, considering there probably are no mature spores present as well. BTW, a sporocarp this size probably would produce over 1 billion spores.

Good for terminal cancer patients.

Jonas Salk did research on Calvatia gigantea and cancer patients. He came to poor conclusions IMO. He gave calvacin derived from 5,000 pounds of C. gigantea to a group of terminal cancer patients. Many died. But before dying, the cancers many were dying from had remarkable decreases in size. At the time, the only way to amass 5,000 pounds of C. gigantea was getting mature sporocarps as well as immature. Mature C. gigantea are poisonous. So it is quite possible Salk effectively poisoned his patients. The excellent news is your specimen is in perfect condition for consumption – or for extracting calvacin, which is merely a alcohol-derived tincture of C. gigantea. A single teaspoon of calvacin tincture might save a life. But if the sporocarp is not of a quality you would eat yourself, do not make a tincture out of it. Keep in mind Salk’s experience, and learn from it!
