Geastrum triplex Jungh. |
British distribution: Locally frequent in southern England, becoming much rarer northwards.
World distribution: Temperate and subtropical regions, widespread.
Geastrum triplex, Scotland, 1980, in Sycamore (Acer pseudoplatanus) woodland behind dunes. (Regrettably, there is a reason not to name the site.)
One of the more common earthstars in Britain. As can be seen in the right of the photograph, when immature it looks remarkably like a tulip bulb, until the outer layer splits and opens in the characteristic star-like shape. In this species, the splitting of the outer layer also forms a conspicuous collar. The puffball-like centre is then exposed, and as with the puffballs themselves, heavy rain or water dripping off overhead branches puffs out the spores through the apical opening.
A saprotroph amongst leaf litter in well drained open woodland, in hedgebanks, etc., usually on lime-rich soils.
