Geastrales
Geastrales is an order (biology), order of puffballs, gasterocarpic Basidiomycota, basidiomycetes (fungi) that are related to Gomphales. The order contains the family (biology), families Geastraceae, which includes the "earthstars" formerly placed in Lycoperdales or Phallales, and also Schenellaceae, Sclerogastraceae and Sphaerobolaceae. About 160 species are biological classification, classified in this order, divided among seven or eight genera, including ''Geastrum'', ''Myriostoma'' and ''Sphaerobolus''. ''Sphaerobolus'' species are known as "shotgun fungus" or "cannonball fungus". They colonize wood-based mulches and may throw black, sticky, spore-containing globs onto nearby surfaces. In ''Geastrum'', once mature, the exoperidium splits into a variable number of rays, which give them their visible star shape. The exoperidial rays are there to protect the endoperidial body and orchestrate spore dispersal.Kuhar, F., Castiglia, V., & Papinutti, L. (2013). Geastrum species of ...

Geastrum Triplex
''Geastrum triplex'' is a fungus found in the detritus and leaf litter of hardwood forests around the world. It is commonly known as the collared earthstar, the saucered earthstar, or the triple earthstar—and less commonly by the alternative species name ''Geastrum indicum''. It is the largest member of the genus ''Geastrum'' (or Geastrum, earthstar fungi) and expanded mature specimens can reach a tip-to-tip length of up to . Immature basidiocarp, fruit bodies are spherical—somewhat resembling puffballs with pointed beaks—and are partially or completely buried in the ground. As the fungus matures, the outer layer of tissue (the exoperidium) splits into four to eight pointed segments that spread outwards and downwards, lifting and exposing the spherical inner spore sac. The spore sac contains the gleba, a mass of spores and fertile mycelial tissue that when young is white and firm, but ages to become brown and powdery. Often, a layer of the exoperidium splits around the p ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
