In this contribution, new data concerning bryophytes, fungi and lichens of the Italian flora are presented. It includes records, confirmations or exclusions for bryophyte genera Acaulon , Campylopus Entosthodon Homomallium Pseudohygrohypnum Thuidium fungal Entoloma Cortinarius Mycenella Oxyporus Psathyrella lichen Anaptychia Athallia Baeomyces Bagliettoa Calicium Nephroma Pectenia Phaeophyscia ...

Terrestrial productivity today is regulated by stomatal movements, but this has only been the case since “stomatophytes” became dominant on the land 390 million years ago. In this review,we examine evidence for the functionof early stomata, foundonor near the reproductive structures of bryophyte-like fossils, and consider how this function may have changed through time as vascular plants evolve...

The occurrence of endogenous indole-3-acetic acid and ethylene in bryophyte tissue was tentatively demonstrated using gas chromatography, high performance liquid chromatography, and double-standard isotope dilution techniques. Rapidly elongating stalks (or setae) of Pellia epiphylla (L.) Corda sporophytes contain approximately 2.5 to 2.9 micrograms per gram fresh weight of putative free IAA. Et...

Non-vascular plants rely on sperm to cross the distance between male and female reproductive organs for fertilization and sexual reproduction to occur. The majority of non-vascular plants have separate sexes, and thus, this distance may be a few millimetres to many metres. Because sperm need water for transport, it has been assumed that sperm lifespans are short and that this type of sexual rep...
