Theythen rest during the the spring under favor-able conditions each cell ofthe teleutospore germi-nates, producing a shortmycelium called a promy-celium, as shown in , 223. This promy-celium is usually dividedinto four cells. From eachcell a short, pointed pro-cess is formed called a<l sterigma. Through thisthe protoplasm moves andforms a small gonidium onthe end, sometimes calleda How the fungus gets from the wheat hack to the harherry.—If these sporidia from the teleutospores are carr
