Research output: Contribution to journalArticlepeer-review


A new variety of Ganoderma tsugae var. jannieae S. Wasser, Zmitr. et M. Didukh was described as new for science, revealed in natural collections from China. Certain specific features that G. tsugae var. jannieae has, differing it from type material on Ganoderma tsugae var. tsugae, was revealed. These characteristics are: (i) almost full absence of inflated skeletals in medullar tissues and poor expression (to absence) of white outer fleshy medullar tissue; (ii) more pronounced pillars and, consequently, finer spore ornamentation; (iii) slightly thicker spore wall; (iv) a consistently shorter and broader spore apex; (v) extremely poor expression of plate-like depressions of the spore surface. This material corresponds well to G. tsugae and also seems to gravitate to G. resinaceum, but sharply differs from the latter by smaller pores and thinner and softer context. The basidiome morphology and cultural characteristics of the nature material of the new variety are described and discussed.
