摘要利用从田纳西州东北部森林中自然发生的树苗根尖提取的DNA，对与美国板栗（Castanea dentata）相关的外生菌根真菌进行了鉴定。共记录了18个分类群，虽然其中之一（Oidiodendron maius）是令人惊讶的，因为它以前已被报道形成什么似乎是菌根协会只与杜鹃花科的成员。三分之一的记录分类群是红菇属或乳菇属的代表（红菇科的成员），以及其他三个属（Cortinarius，Tomentella和Tricholoma，每个属有两个物种）。本文提供的数据至少表明，红菇科的成员是最常见和最广泛的外生菌根真菌与自然发生的个人在北美东部的森林中，它曾经是占主导地位的美国板栗。然而，应该指出的是，我们的数据是有限的，因此最好被认为是初步的。
ABSTRACT The ectomycorrhizal fungi associated with American chestnut (Castanea dentata) were characterized using DNA extracted from the root-tips of naturally occurring saplings from a forest in northeastern Tennessee. A total of 18 taxa were recorded, although one of these (Oidiodendron maius) was surprising because it has been reported previously to form what appear to be mycorrhizal associations only with members of the Ericaceae. One-third of the recorded taxa were representatives of the genera Russula or Lactarius (both members of the family Russulaceae), and three other genera (Cortinarius, Tomentella, and Tricholoma, each represented by two species). The data presented herein at least suggest that members of the Russulaceae are among the most common and widespread ectomycorrhizal fungi associated with naturally occurring individuals of American chestnut in the forests of eastern North America in which it was once dominant. However, it should be pointed out that our data are limited and thus are best considered as preliminary.
