|Calostoma fuhreri, a puffball with short gelatinous stem (to 20 mm long) and globose mesoperidium (which contains the spore sac) up to 8 mm diam., mouth red. Outer layer not falling away in one piece (as in C. fuscum) but persisting as small back granules. In semi-arid areas (Little Desert). RARE.|
Peridium. Brownish/black. 8-10mm diameter, 6-10mm high. Globose to obpyriform Exoperidium (outer layer) flakes off leaving a rough, scurfy surface. The endoperidium (inner layer) is dark grey/brown.
Hypogeous. 17-25mm x 5-10mm. Consists of gelatinous, brown mycelium made up of irregular 1mm loosely woven strands resembling seaweed. These tend to stick together when moist but separate on drying.
Definite. Slightly raised, Slit-like, the raised slit slightly curved with 5-8 side slits, each terminating in an arc. Pinkish, becoming white and floury from the spores.
Spores. Elliptic, white, smooth. 22 - 25( x 10 - 11.5(, remarkably large for a puffball.
The fungus was first reported for South Australia in October 1998. It was also fruiting in May 1999. It forms dense black/ashy coloured patches amongst the shards of granite near the top of Mount Monster in the South-east of S.A. Each fruiting body produces white puffs of spores at the slightest touch. Edibility unknown. Too small to be of interest.
