Observation 23336: Scleroderma areolatum Ehrenb.
When: 2009-07-19
Who: ANC
No herbarium specimen

Notes: I found a string of these growing level with the gravel walkway. They have a tan outer skin and a rich brown foam-like interior. Is it a puffball of some sort? If you need additional bare-eye details to ID it, please let me know specifically would help.

Many Scleroderma species have stipes

or a columella-like basal attachment. I’m not sure of the specific differences between a basal tuft (puffballs) and columella (a vestigial stem dispersing throughout the gleba, as in Thaxterogaster pinquis and Truncocolumella citrina). At least one species of Scleroderma remains mostly underground (Scleroderma hypogaeum). The debate continues as to whether these are becoming hypogeous truffle-like fungus, or epigeous mushroom-like fungus. Almost always in my experience S. areolatum is epigeous (above ground in part or whole).
