外生菌根的地下子实体采自代表花旗松的一系列典型自然生境的10个样地中。对所有样方的计算表明，总干物质生物量是1．3kg／ha，单个样方的最大生物量是9．9kg／ha。记录了47种地下生真菌；有14种共占总生物量的94％。颗粒大团囊菌（Elaphomycesgranulatus），高山腹菌（Gautieriamonticolar），革质辐片包（Hysterangiumcoriaceum），变红白腹菌（Leucogasterrubesceus）和公园须腹菌（Rhizopgonparksii）5个种占生物量的73％。与研究区域内的地上真菌相比较，地下真菌的子实体生产量春季比秋季高，生境分为5个类型（WOG湿润过熟林，MOG中湿过熟林；DOG干旱过熟林；MM中湿成年林；MY中湿幼年林）；形成两个梯度：湿润──干旱和幼林──过熟林。MM生境的生物量最大（2．2kg／ha），DOG生境最小（0．7kg／ha）。个别的种表现出强烈的季节性变化，大多数种有春或夏季的生长峰。有些种子实体产生也因生境不同而有差异，例如，Leucogasterrubescons的生长高峰出现在DOG生境，而Leucophlepsmagnata的生长高峰出现在非过熟林生境上，相比之下，Rhizopegonrincicolor在所有生境中都有分布。对样地分布范围的分析表明，样地面积小（≤800m~2）会导致过高估计子实体产量，因为生物量与高估值十分不一致。另外，?
The underground fruiting bodies of ectomycorrhizas are collected from 10 plots of a series of typical natural habitats representing Douglas fir. Calculations for all quadrats showed that the total dry matter biomass was 1.3 kg / ha, and the maximum biomass per single quadrat was 9.9 kg / ha. 47 species of underground fungi were recorded; 14 species accounted for 94% of the total biomass. Five species of Elaphomyces glandulatus, Gautieriamonticolar, Hysterangium coriaceum, Leucogaster rubesceus and Rhizoporparksii accounted for 73% . Compared with the above-ground fungi in the studied area, the yield of subterranean fungi of underground fungi was higher in spring than in autumn, and the habitats were divided into five types (WOG wet over-mature forest, MOG wet-over-mature forest; DOG drought overribulin forest; MM Wet adult forest; MY wet young forest); two gradients are formed: moist - drought and young forest - over-mature forest. The biomass of MM habitat was the largest (2.2 kg / ha), and the DOG habitat was the smallest (0.7 kg / ha). Individual species show strong seasonal changes, most of which have spring or summer peak growth. For example, the growth peak of Leucogasterrubescons appears in the DOG habitat and the growth peak of Leucophlepsmagnata occurs in the non-overbred forest habitat, compared to the distribution of Rhizopegon rincicolor in all habitats . Analysis of the plots’ distribution range shows that small sample plots (≤800m ~ 2) lead to overestimation of fruiting body yields because biomass is disproportionately high with high valuations.
