These two are photographic field guides that teach you to identify moss and liverwort species from the Sequoia National Park. I didn't count, but I would estimate that 60 species are covered between the two videos. They are organized first by elevation and then by the substrate on which they grow. Mostly the identifications are based on features of the leafy or thalloid gametophyte, but photos of the sporophytes are also shown.
I think that it is a really nice guide and it definitely makes me want to get out and explore the bryophytes of California. However, I am not sure how I am going to take these guides out to the field with me. Does this mean that I have to break down and get a smartphone?
Do you have a favorite species? Though Funaria hygrometrica is the species that I study for my laboratory research, I would have to say that my favorites of the bunch are the Fissidens species. Those opposite leaves that clasp around the leaf above are such a neat shape.
If there are any issues viewing the videos above they can also be watched here (first half) and here (second half).
