从22个地点，包括扰动和未受干扰的栖息地在澳大利亚东部的土壤中的分布的Rhizophlyctis rosea进行了检查。Rh.在60%的地点（67%的农业土壤和33%的自然土壤）的诱饵上观察到玫瑰花。在干扰的栖息地，从四个网站，经历不同的温度范围内的样品进行了评估的频率，丰度，菌体数量和密度的毒饵殖民化。将透镜纸诱饵置于具有无菌去离子水和风干土壤的皮氏培养皿中，并在20、35或40 ℃下孵育长达4天，以及在冷冻（-15 ℃）和加热（80 ℃）土壤后在20 ℃下孵育。丰度、频率、菌体数量和定殖密度在所分析的样品中各不相同，皮特镇底部的丰度、菌体数量和密度最大，皮特镇底部和Narrabri土壤的频率最高。所有菌株在加热和冷冻处理后均能生长并释放游动孢子。冷冻土壤前诱饵的数量和密度的定殖的诱饵，而加热的频率和丰富的Rh下降。玫瑰色。
The distribution of Rhizophlyctis rosea was examined in soils from 22 locations including disturbed and undisturbed habitats in eastern Australia. Thalli of Rh. rosea were observed on baits from 60% of the sites (67% agricultural and 33% natural soils). Within the disturbed habitats, samples from four sites that experience different temperature ranges were assessed for frequency, abundance, number of thalli and density of colonization of the baits. Lens paper baits were placed into Petri dishes with sterile deionized water and air-dried soil and incubated for up to four days at 20, 35 or 40°C, and at 20°C after freezing (-15°C) and heating (80°C) the soil. The abundance, frequency, number of thalli and density of colonization varied among the samples analysed, with the greatest abundance, number of thalli and density for Pitt Town Bottoms and the highest frequency for Pitt Town Bottoms and Narrabri soils. All isolates grew and released zoospores after heat and freezing treatments. Freezing soil before baiting increased the number of thalli and density of colonization of baits, while heating decreased the frequency and abundance of Rh. rosea.
