The resident exhibition for Reading Science Week was the Imagining Science Symbiosis Project about which Dr M has posted before and within which Dr M is deeply embedded!

A very large order comprising most of the pleurocarpous mosses with perhaps 4400 species world-wide!

An order of epiphytic acrocarps, about 100 species world-wide and forming cushions on trees or rocks. The leaves are lanceolate and recurved at the margin, and are either overlapping when dry (e.g. Orthotrichum) or twisted when dry (e.g. Ulota).

Bryales is a large order of acrocarpous mosses containing about 500 species world-wide, and found growing on soil, rocks and walls.

A small order in Britain (but about 135 species world-wide), including a very common and characteristic species, Funaria hygrometrica, growing on old bonfire sites, disturbed ground and garden and other horticultural habitats.

Dr M loves Grimmiales, well it’s such a wonderful bryological name!  And a great big order of epiphytic acrocarpous mosses of walls and rocks and boulders and related habitats.

Dr M is potty about Pottiales, partly because it can be a tricky group to deal with, partly because it is a common and widespread group of acrocarps so it is an important order of mosses and partly just because Pottiales is such a great name!

This is a rather characteristic order of acrocarpous mosses recognised by the generally very long, narrow leaves.

A really very characteristic group of mosses, the genus Fissidens often being mistaken for leafy liverworts by beginning students due to the complanate (flattened) shoots, and the leaves in two-ranks.

The Polytrichales is a characteristic order of acrocarpous mosses with robust, narrow leaves and a transparent sheathing base and with longitudinal lamellae on upper (adaxial) surface
