The assessment of degree of intensity of a variation of a standard panel from bilateral morphological characters of sheet of a Betula verrucosa is resulted, direct impact makes on a normal which course of ability to live the pathogenic factor. As the last in experiment it is defined basidium macromycet Inonotus obliquus (Pers.: Fr.) Pilat. The width of the left and right halves of sheet, length of a string of the second order, the second from the sheet establishment, distance between the establishments of the first and second string of the second order, distance between the ends of the same string and angle between the main string and the second from the establishment of sheet a string of the second order have compounded a complex of analyzed morphological characters of assimilating apparatus of Betula pendula Roth. It is positioned that level of morphogenetic stability of development infested and healthy exemplars of trees of a birch differs. As has shown the relative analysis of mathematical expectations of sizes of bilateral morphological characters of the assimilating device of healthy and amazed tinder mushroom Inonotus obliquus (Pers.: Fr.) Pilat Betula verrucosa in wood plantation, at healthy trees of a Betula verrucosa, growing in plantation, the dimension of sheet plates on the average more than at infected xylotrophic basidium macromycet of copies of trees of a Betula verrucosa in a large forest.
