Liverwort spore case. Light micrograph of a vertical section through a spore case (sporophyte) from a liverwort (Pellia epiphylla). Numerous spores (small,round,brown) and their coiled elaters are in the capsule,the round area at centre right. This capsule is attached by a seta (stem) to the foot area (centre left). The whole structure of capsule,seta and foot is together called a sporophyte. The sporophyte is enclosed within the petal-like calyptra (across top and bottom) that protects the sporophyte until the spores are mature and ready to be released. This liverwort is commonly found on wet rocks by streams | |
