This is the first extensive investigation that quantifies natural mycoparasitic relationships in the phyllosphere. The presence of Ampelomyces spp. was quantified in naturally occurring powdery mildew fungi collected in Hungary and Romania between 1992 and 1995. A total of 570 samples was studied representing 27 species (nine genera) of the Erysiphaceae infecting 41 host plant genera. The incidence of Ampelomyces spp., determined as the proportion of samples in which intracellular pycnidia were present, varied between 4.3 and 68.8% in the host fungal genera studied. The intensity of mycoparasitism, defined as a percentage of the powdery mildew mycelia parasitized by Ampelomyces, ranged from 0.15 to 65%. Both the incidence and the intensity of mycoparasitism showed the lowest values in Blumeria graminis (DC.) Speer collected from wild and cultivated monocotyledons, while the highest values were found in Arthrocladiella mougeotii (Lév.) Vassilkov infecting Lycium halimifolium Mill. plants. The paper reports for the first time the natural occurrence of Ampelomyces in Sawadaea bicornis (Wallr.∶Fr.) Homma on maple.
这是首次对叶际中自然存在的真菌寄生关系进行的广泛调查。对1992年至1995年期间在匈牙利和罗马尼亚采集的自然发生的白粉菌中Ampelomyces属的存在情况进行了定量分析。共研究了570个样本，代表了感染41个寄主植物属的白粉菌科的27个物种（9个属）。在所研究的寄主真菌属中，Ampelomyces属的发生率（以存在细胞内分生孢子器的样本比例确定）在4.3%至68.8%之间变化。真菌寄生强度（定义为被Ampelomyces寄生的白粉菌菌丝体的百分比）范围为0.15%至65%。真菌寄生的发生率和强度在从野生和栽培单子叶植物上采集的禾本科布氏白粉菌（Blumeria graminis (DC.) Speer）中显示出最低值，而在感染枸杞（Lycium halimifolium Mill.）植物的穆氏节壶菌（Arthrocladiella mougeotii (Lév.) Vassilkov）中发现了最高值。该论文首次报道了在枫树上的双角锯霉（Sawadaea bicornis (Wallr.∶Fr.) Homma）中自然存在Ampelomyces。
