Observation 168545: Calvatia craniiformis (Schwein.) Fries

When: 2014-06-12

Collection location: Big Thicket, Polk Co., Texas, USA [Click for map]

Who: Ron Pastorino (Ronpast)

No specimen available

These were growing in mixed woods of the Big Sandy Creek Unit(Big Thicket National Preserve).
They looked like 4 large brown cupcakes sitting in the forest duff. Eventually I learned they were the remains of a Calvatia species that had lost its spore case with the sterile base remaining.
There are about 3 candidates but examining a few of the residual spores strongly suggested C. craniformis.
The spores were small, ~ 3-4 microns and mostly smooth.
Also this species is the most likely to be growing in the woods rather than open pastures, etc.
