Observation 156866: Scleroderma Pers.

When: 2013-12-31

Collection location: Tallahassee, Florida, USA [Click for map]

30.5759° -84.238°

Who: Chris Hay (hayfield)

No specimen available

GPS coordinates are representative for this neighbourhood, where mushrooms were abundant on lawns where pine and oak trees where never far (mycorrhizal species may be with either the hardwoods or conifers).

I measured the thickness of the skin from a small slice off the top part. It was between 1-2mm, though maybe it’s thicker below? The fbs were fairly large, about 6cm across. All the specimens in this yard were fairly old and splitting apart already.

Sclerodermas should be considered poisonous until proven otherwise. In 1997 a 110-pound pot-bellied pig died in Vancouver, WA. after eating Sclerodermas. A human the same size would likely have died as well. DO NOT EXPERIMENT!

Sclerodermas are mycorrhizal with many tree species, although some may be species specific (i.e. found with only one host species), and frequently found anywhere after temperatures exceed 80 degrees. They may be soft and powdery when very mature, or hard and rubbery when young. When very young they are likely to be white, marbled white and yellow, or with various shades of purple and purple black as the gleba (interior) matures. The peridium (outer skin) finally breaks, and releases spores into the atmosphere, where they are spread worldwide.

The skin (peridium) is often thinner at the top and thicker at the base, near the pseudo-stem. If they are dug up carefully they often have a convoluted stipe (stem) and thick, ropey rhizosmorphs leading outward. Because these are easily grown, most nurseries already have them, and nursery stock is one means of being spread.

Thanks, Daniel, for the info. I will get a sectioned base next time I find a Scleroderma, and be mindful of warts or lack thereof. Maybe I’ll be back there in Florida at the right time some day in the future, if so I’ll be sure to take a closer look.

Strongly doubt

Scleroderma citrinum group. S.c. has erect hard warts on the scales. This has none.

It is definately a Scleroderma. Showing the sectioned base would be important to determining species.
