The present study was conducted to examine the influence of interaction between ammonia fungi [Amblyo-sporium botrytis,Ascobolus denudatus, Lyophyllum tylicolor, Coprinus phlyctidosporus (early occurring fungi), Hebeloma vinosophyllum (a late occurring fungi)] in their ocurrence and succession, by mono-and mixed cultures with inocula of spores or vegetative mycelia. The culture media were <gamma>-ray-steri-lized forest soils sampled at different periods after urea treatment. All tested fungi could grow on the urea-treated soils obtained at any period tested. Ithin 1.5 months after urea treatment, the growth rate of H. vinosophyllum was higer in the cultures on samples of L-F-horizon than in those on samples of HA-horizon. Thereafter, the growth rate was higher in the cultures on samples of HA-horizon. The quantity of fruit-bodies of this fungus increased suddenly in the cultures on samples of both layers, from 2.5 months after urea-treatment. Fruiting of H. vinosophyllum in the culture … More s on samples of both layers was inhibited by all of the tested fungi except for A. botrytis. A. botrytis also inhibited the fruiting of H. vinosophyllum cultured on the samles of the L-F-horizon. On the contrary, it accelerated the fruiting of H. vinosophyllum cultured on the samles of the HA-horizon. The degree of inhibition was higher in the mixed cultures on samples of L-F-horizon than in those on samples of HA-horizon. The amounts of NH_4-N and inorganic nitrogens, and pH values before culture were higher in HA-horizon than in L-F-horizon. H. vinosophyllum is assumed to propagate in HA-horizon evasively as the results of interspecific mycelial interactions between H. vinosophyllum and early occurring fungi. All tested fungi incubated in the monocultures with spore inocula grew on the urea-treated soils sampled at any period tested. Cultures with spore inocula showed delayed fruiting in tested fungi except for L. tylicolor. The fruiting period in the monocultures with mycelial inocula corresponded with that in nature. These results suggest that the mycelial stage is the main potential form of ammonia fungi in nature. Less

本研究是针对真菌真菌氨的影响，通过孢子或营养菌丝体的单群培养物，培养基是尿素治疗后的经过测试的真菌可以在经过1.5个月的尿素期间获得的尿素处理的土壤。 . The Quantity of Fruit-Bodies of This cleaveless in the crunchers on Samples of Both Layers. Eatment of H. Vinosophyllum in The Culture… More S on Samples of Both Layers Was inHibited by all of the tested funghtrytis. L-f-horizo​​n. On the相反，它加快了在H-f-f-horizo​​n的样品中培养在HA-HORIZON的Samels上的Vinosophyllum的果实。在H.-horizo​​n的培养物中，vinosophyllum和早期的真菌之间的培养时间高菌丝菌的单一培养在自然而然的结果表明，氨气的主电位形式在本质上是较少的
