Viable sclerotia of the cotton root-rot fungus, Phymatotrichum omnivorum, have been found under natural conditions in the soil of infested cotton fields in Texas, showing that this fungus is a soil organism not restricted to living roots of susceptible host plants, but having an independent means of over-wintering and dissemination.
在德克萨斯州受感染的棉田土壤中，发现了棉花根腐病菌（Phymatotrichum omnivorum）有活力的菌核，这表明该真菌是一种土壤生物，不仅局限于易感宿主植物的活根中生存，而且还有一种独立的越冬和传播方式。
