 The treatment of this species by certain <unk> well illustrates the pitfalls that lie in wait for those who worship at the shrine of <unk> classification ... The only feature of those outlined in which the species differs from others of Geastrum is the somewhat primitive hymenium . In the developing plant the <unk> cavities are separated by <unk> plates so tenuous as to be overlooked by the <unk> worker . Each cavity is filled with basidia somewhat irregularly arranged in clusters ( like those of Scleroderma ) and not in the definite palisade of the species which have been studied . This difference disappears as maturity is reached , when plants resemble closely the <unk> of any other member of the genus . The <unk> is then unable to indicate any point of difference by which " Astraeus " may be separated from Geastrum , which indicates that the name should be discarded .
