Abstract

Fungi were observed in the central hydroid strand of underground axes of Polytrichum commune Hedw. Hyphal strands appeared continuous from hydroid to hydroid in certain cases, apparently penetrating the lateral walls of hydroids. Hyphae were also observed on the epidermal surfaces of the rhizomes. Newly initiated gametophores and mature gametophores appeared robust and healthy. Whether the moss-fungus association is a host-parasite relationship or mycorrhizal-like was not determined.
