Only partially mature area

of sporocarp are the dark purplish areas in the cross-section, which indicate most of this sporocarp are still quite immature. I’m guessing more mature material in 2-6 weeks. I’ve had Sclerodermas under my home for the last 15 years. In protected , dry environments they can last for considerable time, not just overwintering as some authors have stated.

AFAIK (as far as I know) Scleroderma are all mycorrhizal, meaning there must be either a tree or shrub nearby as a host. A birch tree 30 feet tall could be the mycorrhizal host of this collection if it were located 60 feet away…

Is that part of bark mulch, or is it from a nearby tree? S. citrinum is widely mycorrhizal, and the areolate cracking of the peridium makes S. citrinum a strong possibility. Like most mycorrhizal fungi, though, difficult to be certain without spore data, or a slice through the center of a sporocarp. Many Scleroderma stain quickly after slicing, especially in the peridium or at the base.
