Three Stars! Geastrum triplex x 3 in Gunnersbury Triangle
A different Geastrum in Alick Henrici’s hand, so we now have two species of the genus in the Triangle. It has only 2 layers, not the 3 (obviously) of G. triplex. It looks much like G. hygrometricum, the Barometer Earthstar, but there are at least 10 species so we’d best wait for Alick’s microscope examination of the spores.
