Abstract

We have studied the sporophyte-gametophyte junction at the post-meiotic stage in five pleurocarpous mosses: Isothecium myosuroides Brid., Leucodon canariensis (Brid.) Schwaegr., Leptodon longisetus Mont., Neckera cephalonica Jur. & Unger, and Neckera intermedia Brid. In all five species the foot does not penetrates the leafy caulidium. The junction in all of them corresponds to a “bryalean pattern”, with transfer cells both in the gametophyte and sporophyte. However, except in Neckera intermedia, there were several layers of foot transfer cells, deviating from the typical 1:1 arrangement in this model. At this stage, the tissues of both foot and vaginula were degenerating. Vaginular cells surrounding the foot became empty and thin-walled. Opportunistic microorganisms were often found. The five species differ with respect to the number of layers of transfer cells and the degree of development of foot hydroids.
