“…Microfrullania. Classification systems for extant Frullania species can be tested using molecular phylogenies (Hentschel et al 2009). These phylogenies allow to identify characters that support supraspecific entities as well as homoplasious characters that cannot be used for classification.…”

“…Stelae of F. subg. Microfrullania representatives lack secondary branches and deposits (Hentschel et al 2009). The observed single F. varians spore is at the lower end of size variation observed for spores of extant Frullania; details of the spore wall are unfortunately not visible.…”

“…Some 25 species have been described from these ambers, of which nine are currently accepted (Grolle 1985(Grolle , 2003Heinrichs et al 2012). Frullania is characterized by its often reddish pigmentation, incubous leaves divided in a dorsal lobe, a ventral laminar stylus and a ventral lobule often forming a water-sac, rhizoids originating at the base of usually bilobed underleaves, male inflorescences located on short, almost leafless spicate branches, and beaked perianths often provided with ridges and tubercles (Schuster 1992;Hentschel et al 2009). The supraspecific classification of Frullania is largely based on gametophytic characters (von Konrat & Braggins 2001a); however, Schuster (1992) and von Konrat et al (1999) emphasized the importance of sporophytic characters for the classification of Frullania.…”

We document the sporophyte of the extinct Frullania varians based on an inclusion in Late Oligocene Bitterfeld amber from Germany. The sporophyte consists of a short, ca. 45 µm thick seta that exceeds the perianth only slightly; the elongate-ovate, acute valves of the opened capsule are about 225 µm long, curved backwards and consist of an epidermal and an internal layer. Cell walls of both layers possess nodulose trigones. Several trumpet-shaped, unispiral elaters are fixed to the upper third of the internal valve layer. They have a length of ca. 150 µm and a diameter of 15–18 µm. A subglobose structure of 19 µm diameter is interpreted as a degraded spore. Fossil elaters and spores as well as capsule wall details of Frullaniaceae are described for the first time. doi:<a href="http://dx.doi.org/10.1002/mmng.201200009" target="_blank">10.1002/mmng.201200009</a>

Spore germination, early development and some notes on the effects of in vitro culture medium on Frullania ericoides (Nees) Mont. (Frullaniaceae, Marchantiophyta)

In bryophytes, establishment can occur by a sexual or asexual process, but the production of spores enables colonization of a wider range of habitats and substrates than can asexual propagules. Successful germination is critical for establishment in a new environment. Th is paper addresses germination and sporeling development in Frullania ericoides, a leafy liverwort species. Fresh spores were inoculated in vitro in diff erent culture strengths of Knop's nutrient solution (one-fourth strength, half strength, full strength, one and a half strength and double strength), in order to evaluate the eff ects of this solution on spore germination and on the development of external protonema. On the fi rst assessment, spore germination was observed at all the concentrations. Germination was endosporic, with cell division and proliferation, resulting in a globular protonema, within the spore wall. Beginning at the fourth week, the development of tightly concave primordial leaves was observed in all but the double-strength medium. Th roughout the period of study, the treatments with lower concentrations exhibited external protonema with greater lengths. Th e double-strength treatment was statistically diff erent from other treatments in at least two parameters. Th e results of this study demonstrate the potential of in vitro culture techniques for bryophyte spore studies and germplasm preservation.

There are more than 20,000 species of bryophytes in the world. Among them, almost all of the liverworts (Marchantiophyta) possess beautiful cellular oil bodies from which over several hundred new terpenoids and phenolic compounds with more than 40 new carbon skeletons have been isolated. Some of the isolated terpenoids and aromatic compounds from liverworts show allergenic contact dermatitis, cytotoxicity, antimicrobial, antifungal, antiviral, insect antifeedant and mortality, antioxidant, NO production and plant growth inhibitory, neurotrophic and piscicidal, tublin polymerization inhibitory, muscle‐relaxing, and liver X‐receptor alpha (LXRα) agonist and LXRβ antagonist activities among others. The bio‐ and chemical diversities, chemical analysis of bryophytes, including extraction, distillation, purification, thin‐layer chromatography (TLC), gas chromatography (GC) and gas chromatography/mass spectrometry (GC/MS), and high performance liquid chromatography (HPLC) analysis of oil bodies of liverworts, and biosynthesis of typical bis‐bibenzyls, biological activities, chemosystematics, and chemical phylogeny of bryophytes are surveyed.
