Sporophytes are raised on stalks to facilitate spore dispersal, but unlike other mosses, Sphagnum stalks are produced by the maternal gametophyte. Tetrahedral haploid spores are produced in the sporophyte by meiosis, which are then dispersed when the capsule explosively discharges its cap, called an operculum , and shoots the spores some distance.
Compared to other Sphagnum species, Sphagnum squarrosum retains fewer spores within its capsules after dispersal, resulting in greater spore release and wider distribution. [ 9 ] Research on island colonization reveals that S. squarrosum is an effective long-distance disperser, successfully establishing populations as far as 40 km (25 mi) from ...
Mature spore capsules on Sphagnum fimbriatum, showing the species' prolific spore production Sphagnum fimbriatum is monoecious , with male and female structures on the same plant. [ 7 ] The reproductive cycle in temperate regions follows seasonal patterns: it begins in late summer with the development of male reproductive structures (antheridia ...
This connection is supported by shared morphological traits, including the production of sphaerophorin and structural similarities in reproductive anatomy. Both families are part of a broader clade of mazaedia-producing lichens, underscoring the importance of passive spore dispersal in their evolutionary history. The ability to form mazaedia ...
Columella – an axis of sterile tissue which passes through the center of the spore-case of mosses. Dehisce – meaning to split along a natural line, refers to the split in the capsule where the operculum detaches. Diplolepidous – a type of peristome found in Bryidae, in which there are two rings of teeth - the inner endostome and outer ...
Moss peat is made from Sphagnum. Commercial. Peat is a fuel produced from dried bryophytes, typically Sphagnum. Bryophytes' antibiotic properties and ability to retain water make them a useful packaging material for vegetables, flowers, and bulbs. [49] Also, because of its antibiotic properties, Sphagnum was used as a surgical dressing in World ...
In leptosporangiate ferns, the annulus located on the outer rim of the sporangium and serves in spore dispersal. It consists typically of a ring or belt of dead water-filled cells with differentially thickened cell walls that stretches about two-thirds around each sporangium in leptosporangiate ferns. The thinner walls on the outside allow ...
Sphagnum angustifolium, the fine bogmoss, [2] is a species of peat moss with a Holarctic distribution. A member of the S. recurvum species complex within Sphagnum section Cuspidata, it is a relatively small, green to yellowish moss that grows in wet, moderately nutrient-rich mires, typically forming carpets or growing intermixed with other peat moss species.
