The giant puffball offers a mycological example of Charles Darwin's observation that "more individuals are produced than can possibly survive" ( On the Origin of Species, 1859, p.63). A 30 cm- diameter fruiting body can produce seven trillion spores. If every one of these germinated, founded a colony, located a mate and sired at least one fruiting body, all of the state of Ohio (almost 45, 000 square miles) would be submerged under a waist- deep pile of puffballs! Clearly, the vast majority of spores do not survive.

Lichens Fungi + algae or cyanobacteria Lichens (la ɪ k ə n/) are symbiotic associations of a fungus (the mycobiont) with a photosynthetic partner (the photobiont also known as the phycobiont) that can produce food for the lichen from sunlight. The photobiont is usually either green alga or cyanobacterium . Lichens fulfill many roles: as in providing dyes and medicine to indigenous people, winter feed for caribou and as occurring as destructive agents in stone buildings and monuments.
