 A distinguishing feature of the Sclerodermatineae is the diversity of morphologies within the group . The hymenomycete genera Boletinellus , Gyroporus , and Phlebopus are typical boletes with a cap and stipe . However , each of the gasteroid Sclerodermatineae has a distinct morphology . Species of Astraeus have an " earthstar " morphology where the outer peridium peels back in sections . The gleba of Pisolithus is partitioned into hundreds of membranous chambers . Scleroderma is a simple puffball with a thin outer skin and a powdery gleba at maturity . Diplocystis and Tremellogaster are each distinct in their morphologies : the former comprises compound fruit bodies each with 3 – 60 spore sacs crowded together , while the latter forms a roughly spherical sporocarp with a thick multi @-@ layered peridium . Calostoma ( Greek for " pretty mouth " ) is morphologically distinct from other gasteroid members , having a fruit body that forms a globed , spore @-@ bearing head composed of a three @-@ layered peridium . About two @-@ thirds of Sclerodermatineae species have a gasteroid morphology , although this may be an underestimate due to the existence of cryptic species that have yet to be formally described . For example , studies of the gasteroid genera Astraeus and Pisolithus indicate the existence of numerous cryptic taxa .
