Starts bulbous and expands to conical or campanulate (bell shaped) before flattening or becoming concave with the cap edges lifting upwards.

The stem is so fragile that when the caps are fully open and mature even a slight breeze or human breath can cause them to break.

Larger specimens may collapse under their own weight and hot sun causes these mushrooms to deteriorate and disappear very quickly.

The specimens studied were gathered in Brazoria county, Texas in 1971 and Cades Cove, Tennessee in 1939.

Specimens were also found growing from the soil in mixed woodland, in layers of fallen pine needles and in leaf covered grass.

The mushrooms were described as being very abundant at times but fleeting and found only during and shortly after rain or in the early morning when heavy dew was present.
