Evidence is presented that several species representing the earliest groups of land plants are symbiotic with fungi of the Mucoromycotina, raising the possibility that terrestrialization was facilitated by these fungi rather than, as conventionally proposed, by members of the Glomeromycota.
In vitro cultivation of bryophytes: a review of practicalities, problems, progress and promise
The first description of a highly distinctive protonema in Buxbaumia viridis opens the way to identify this endangered species in the absence of sporophytes, and the potential rewards of in vitro cultivation are reviewed.
Effects of de- and rehydration on food-conducting cells in the moss Polytrichum formosum: a cytological study.
A cytological study of the effects of de- and rehydration on food-conducting cells in the desiccation-tolerant moss Polytrichum formosum aimed at exploring whether the remarkable subcellular organization of these cells is related to the ability of mosses to survive desicution.
Desiccation tolerance in the moss Polytrichum formosum: physiological and fine-structural changes during desiccation and recovery.
Initial recovery of respiration and photosynthesis is very rapid, and independent of protein synthesis, suggesting physical reactivation of systems conserved intact through desiccation and rehydration, but full recovery takes approx.

It is demonstrated that liverwort–Mucoromycotina symbiosis is mutualistic and mycorrhiza-like, but differs from liverworts–Glomeromycota symbiosis in maintaining functional efficiency of carbon-for-nutrient exchange between partners across CO2 concentrations.
Evolution of the Major Moss Lineages: Phylogenetic Analyses Based on Multiple Gene Sequences and Morphology
Combining morphological and molecular data in the analyses showed that mosses, including Sphagnum, Takakia, Andreaea and Andreaeobryum, form a monophyletic group, provided improved resolution of higher level relationships, and further insight into evolutionary patterns in morphology.

A worldwide survey of liverwort associations with glomeromycotean fungi (GAs), together with a comparative molecular and cellular analysis in representative species, suggests an ancient origin and multiple more recent losses in liverworts.
Exploding a myth: the capsule dehiscence mechanism and the function of pseudostomata in Sphagnum.

The novel functional data on Sphagnum suggest the possibility that stomata first appeared in land plants as structures that facilitated sporophyte drying out before spore discharge and only subsequently acquired their role in the regulation of gaseous exchange.
REGENERATION OF SPHAGNUM
When disc-shaped horizontal slices of peat cores were kept for several months in a saturated atmosphere in a cool greenhouse numerous new shoots of Sphagnum papillosum were produced, suggesting some kind of hormonal control of innovations akin to apical dominance in vascular plants and a more general allelopathic inhibition of spore germination and protonemal growth by green SphagnUM.
Stomatal differentiation and abnormal stomata in hornworts
Structural limitations, a liquid-filled stage in the ontogeny of the intercellular spaces, and spores already at the tetrad stage when stomata open, suggest that their primary role is facilitating sporophyte desiccation leading to dehiscence and spore dispersal rather than gaseous exchange.
