Observation 5792: Geastrum Pers.

When: 2007-12-26

Collection location: Buttonwood, south Key Largo, Monroe Co., Florida, USA [Click for map]

Who: Jason Hollinger (jason)

Specimen available

small earthstar in leaf litter, occasionally on twigs or on surface of rotten limbs, whitish conspicuous mycelial mat surrounding it and binding leaves and twigs together
CAP: ~25mm wide when open, inner spore case ~10-12mm wide, outer skin orangish brown and roughened, inner surface pale buff and cracked, peridium ~1.5mm wide, inner spore case pale to light brown and completely uniform and min dusty/roughened, terminal pore puckered and rupturing through very small hole
SPORE: mass cottony light to medium brown

I’d reported this as wood-dwelling earlier, but in fact that was an unusual specimen. I’ve seen maybe a dozen since then, all in leaves.
