The paper describes the ontogenesis of the epiphytic lichen Lobaria pulmonaria. The studies were carried out in the Karelian forest communities with the period since the last disturbance ranging from 80 to 450 years. Based on the concept of a discrete description of plants and lichens, four periods and 14 age-related states have been distinguished in L. pulmonaria’s ontogenesis. Each ontogenetic state of L. pulmonaria is characterized by a certain thallus size as well as by the presence and the level of development of vegetative diaspores and apothecia on the thallus surface. The possible variants of the species ontogenesis are described.

Lichen Lobaria pulmonaria (L.) Hoffm 的个体发育。在北方地区的植物群落

该论文描述了附生地衣 Lobaria pulmonaria 的个体发生。这些研究是在卡累利阿森林群落中进行的，自上次干扰以来的时期为 80 至 450 年。基于对植物和地衣的离散描述的概念，在 L. pulmonaria 的个体发育中已经区分了四个时期和 14 个与年龄相关的状态。L. pulmonaria 的每个个体发育状态的特征在于特定的菌体大小以及菌体表面上的营养水散和孢子的存在和发育水平。描述了物种个体发生的可能变体。
