A tricostate moss adds to the earliest fossil record of pleurocarpous mosses

"Krassiloviella limbelloides is the second bryophyte described as a result of ongoing studies of the Early Cretaceous Apple Bay flora of Vancouver Island.  Krassiloviella is also the second genus of family Tricostaceae, which provides the oldest unequivocal evidence for the pleurocarpous superorder Hypnanae and a hard minimum age for the group. Revealing aspects of diversity unaccounted for in extant floras, such fossil bryophyte discoveries emphasize the importance of paleontology for efforts aimed at documenting the history of biodiversity

Leaves are tricostate, with a unistratose lamina through most of the leaf length (e.g., fi g. 6). Laminae are delicate, as evidenced by their typically incomplete preservation (e.g., fi gs. 4 E ,6,7 C ). Where unistratose, the lamina is 11.5 – 14 m m thick. However, the lamina is bistratose or tristratose in areas where costae converge at the leaf apex ( fi g. 7 A ,7 C ). The three costae arise separately ( fi g. 7 H ,7 I ).

New web site: with a moss photographic guide

I am pleased to announce that a new website devoted to botanical and ecological imagery,, has just gone live.

The scope is the Northern Forest Region, from Atlantic Canada and northern New England to the prairie edge. 

It currently has searchable image libraries, mostly of high-resolution, stacked, studio photographs, of mosses, sedges, and woody plants; ecological and identification charts and graphics; low-altitude, high-definition air videos; articles and blogs; and previews of books and digital products, some for sale and some free, that will be available in the next few months.
t is a straight-forward site, little text, no clutter, but with several nice features. You can search for images by expanding trees of taxa and habitats, and so, for example, see all the northern forest species of Caliergon, or all the sedges that occur on sandy seacoasts. And you can look at a page of thumbnails of available images and choose the ones you want to compare.

And, of course, it has a space for comments, which I will moderate and very much hope you will take advantage of. I value Bryonet highly, and the chance hear from any of you and get to know you better would be welcome.

The site is the result of four years of intense work by myself and others, backed by the Northern Forest Atlas Foundation and its chair Ed McNeil (who built the aircraft for videography and does the filming), by the Adirondack Program of the Wildlife Conservation Society and its director Zoe Smith, and by a wonderful group of donors. We currently have about 5,000 still images, two hours of video, 24 ecological and identification graphics, 12 products under development, and 8 articles.

More are coming. In the next few years we plan to add images of mammals, birds, herbs, and grasses, and publish photographic guides to mosses and sedges, and the first of our book-length field guides, to woody plants.

So, please visit, and let me know what you think.  Some pages you may like are:
