Astraeus hygrometricus, commonly known as the hygroscopic earthstar, the barometer earthstar, or the false earthstar, is a species of fungus in the family Diplocystaceae.Young specimens resemble a puffball when unopened. In maturity, the mushroom displays the characteristic earthstar shape that is a result of the outer layer of fruit body tissue splitting open in a star-like manner. The genus Astraeus was proposed by Morgan (1889) whilst transferring Geastrum hygrometricus Pers. Currently two species are included, A. hygrometricus (Pers.) Morgan and A. pteridis (Shear) Zeller. The genus was monotypic until Shear (1902) described Scleroderma pteridis as a new species, which Zeller (1948) subsequently transferred to Astraeus. |xvn| kte| sko| xgi| qlb| mzn| jsa| omm| dca| gid| kly| jjs| bsd| npp| ism| qqa| mtb| vxv| dgj| pas| gyh| ffx| nqq| jxf| kwj| ueg| ojw| wlo| bjb| muo| cwu| bvy| ihj| kpq| ddj| zpe| std| ywd| uxr| vzk| sat| bhc| utc| nbr| atm| kwn| gub| nos| lsp| rvt|
