The moss parasites Eocronartium and Jola are close relatives of the rust fungi. Eocronartium has two different parasitic strategies: supplanting the sporophore and utilizing the gametophore transfer cells in some hosts, and parasitizing the gametophore of other hosts. The host-parasite interface in two species of Jola was revealed, showing a similarity with Eocronartium's parasitism of the sporophore. Differences existed, however, between the two species of Jola in details of their interface with intergenerational transfer cells and methods of hyphal penetration through the sporophore. The presented discussion and micrographs will be worth more than the allotted 1
