No herbarium specimen

I almost passed this over thinking it was an insect gall. It was lying on top of the leaf litter under hard woods on the edge of a pine plantation. Two other specimens were located nearby.

Bovista pila looks like a good match.


Agaricales Family Description

Round, becoming detached and rolling about; with white outer skin flaking off to reveal smooth, shiny, bronze spore sac. Mushroom: 1 1/4-3 1/2" (3-9 cm) wide; round or nearly so; attached to ground by single small cord, which breaks at maturity; outer skin pure white, becoming dark pinkish and flaking off in patches; inner skin smooth, shiny, bronze, with cracks or pore opening at top. Spore mass white, then brown. Spores: 3.5-4.3 u; round, smooth, with short, colorless stalk; deep brown.

June-October; overwinters.

B. plumbea is smaller, bluish-gray with age, and attached to ground by clump of fibrous strands.

Single to scattered or many, in pastures, around stables, and in open woods.

Widely distributed in North America.

A common mushroom of grassy areas and pastures, this species grows nearly year-round; hardy ones overwinter and tumble about, unattached to the ground.

could be difficult to determine if these did in fact endure a full winter, but it would be diagnostic for B. pila if even a trace of a basal mycelial cord could be confirmed or denied.

I would hesitate to call it purple brown; it’s more a straight brown-brown. They do appear to be the same as those in damonbrunette’s link.

I don’t see any purple

it’s also the wrong shape and seems to be lacking a sterile base. I would be more inclined to call this a Bovista

Calvatia cyathiformis have a purplish-brown spore mass?

Mxyo correct

yes probably over-wintered

But the cool thing is that they are still very young in so far as spore dispersal is concerned.

the petrified, overwintered carcasses from puffballs of yesteryear?

Tough puffball

These puff balls were very light and not readily compressed. I had to squeeze hard on it to make it release spores. I really did think this was an insect gall when I first saw it. Turns out to be the most intriguing find of the day.

A tumble weed puffball in March is new to me. If this is interesting to somebody else, I can send the specimen.
