Citrine Earthball

Description:

Puffballs with tough yellow cracked exteriors. Emerging fruiting bodies had fluffy white centres as in Pic 3. More mature ones had a purplish gleba which then turned brown as they developed further. The fruiting bodies have no stalk but they arise from a bunch of mycelia that attach them to the ground.

Habitat:

Spotted on grass in a reserve. http://bie.ala.org.au/species/urn:lsid:c...

Notes:

When the puffballs mature the skin peels back releasing purplish brown spores.
S.citrinum is the only host to a parasitic bolete, Boletus parasiticus http://www.mushroomexpert.com/boletus_pa... http://www.mushroomexpert.com/scleroderm...
