Studies on Ectomycorrhizae. XX. Mycorrhizae Formed by Thelephora terrestris on Norway Spruce

Abstract

Ectomycorrhizae of Thelephora terrestris on Picea abies are described and the results are compared to those in the literature. The ectomycorrhizae are well-characterized by a plectenchymatous mantle with netted hyphae below the mantle surface, by cystidia with abruptly thick walls with a distal clamp and often frequent simple septa. Rhizomorphs are slightly differentiated. Naturally grown ectomycorrhizae isolated from soil are compared with synthesized ones.
