Survey of Hypogeous Fungi on Forest Islands in the Great Basin and Arizona

福格尔和国家DEB-9400871次孢菌（松露和假松露）将在大盆地和亚利桑那州的森林岛屿上进行调查。 这些是最不为人所知的物种之一，美国西部可能是一个高度多样性的地区。 此外，Hypocalyptus真菌是关键物种，对重要的针叶林的生存至关重要。 这些真菌也为研究互惠关系提供了一个理想的系统。 它们与林木形成专性外生菌根，依靠啮齿动物传播孢子。 真菌只能存在于内华达山脉-喀斯喀特山脉以东地区分散的森林岛屿中，因此，这为探索真菌的物种形成和物种地理学提供了机会。 这些数据将是有用的，在确定块菌和假块菌建立外生菌的树苗注定要种植在石灰性土壤上，作为小型哺乳动物的饮食来源，并了解因素，为濒危食肉动物维持大型啮齿动物种群。

Fogel And States DEB-9400871 Hypogeous fungi (truffles and false truffles) will be surveyed on forest islands in the Great Basin and Arizona. These are among the least known species, and the western U.S. is potentially a region of high diversity. Additionally, the Hypogeous fungi are keystone species, critical to the survival of the important coniferous forests. These fungi also provide an ideal system for studying mutualistic relationships. They from obligate, ectomycorrhizal associations with forest trees and are dependent on rodents fro spore dispersal. Hypogeous fungi can exist only in the scattered forest islands in the region east of the Sierra Nevada-Cascade ranges; thus, this provides an opportunity to explore speciation and biogeography among fungi. The data will be useful in identifying truffles and false truffles for establishing ectomycorrhizae on tree seedling destined for out planting on calcareous soils, as dietary sources for small mammals, and for understanding factors for maintaining large rodent populations for endangered predators.
