The second record of a natural apogamous moss sporophyte worldwide

An apogamous sporophyte is reported on a gametophore of the moss Fissidens crassipes subsp. warnstorfii (M.Fleisch.) Brugg.-Nann. The apogamous sporophyte is developed in lateral position near the base of the stem of the gametophore. The seta is relatively short and delicate and the capsule without spores. The moss was found growing in a greenhouse in Cairo, Egypt. This is the second record of a natural apogamous moss sporophyte worldwide. A relevant discussion on the phenomenon of apogamy is given.
