本文报道了中国长白山北坡不同垂直分布带中各类乔灌木茎叶上的小形病原真菌(包括少量腐生性真菌)的种类、数量、分布、类群组成及其与生态环境之间的关系。自1980—1984年,共获得真菌标本2500余号,鉴定的真菌种类213种,归属于3个亚门,6个纲,13个目,23个科,97个属。其中已报道的新属1个,新种7个。尚有许多国内新记录种有待陆续发表。研究结果表明,随着不同垂直分布带各种生态因子及其植物群落的改变,各类树木小形真菌的种类、分布和组成有明显的差异。
This paper reports on the species, abundance, distribution of taxa, and the relationship between the taxa and the ecological environment of small-sized pathogenic fungi (including a few saprophytic fungi) on the stems and leaves of all kinds of trees and shrubs in different vertical distribution belts on the northern slope of Changbai Mountain. From 1980 to 1984, a total of 2,500 fungal specimens were obtained, of which 213 species were identified, belonging to 3 submenians, 6 orders, 13 orders, 23 families and 97 genera. Among them, one new genus has been reported and seven new species have been reported. There are still many new record types to be published one after another. The results show that the species, distribution and composition of all kinds of small-fungi are obviously different with the changes of various ecological factors and their plant communities in different vertical distribution zones.
