Lichens under the microscope

Rhizocarpon reductum var fimbriata : England : VC25 East Suffolk : TM4468 : September 2024 : On flint pebble

Free workshop led by Aspen Ecology, and sponsored by the Anglian Microscopy Group and the Suffolk Naturalists’ Society

Saturday, 17 May 2025, 10:00 – 15:00
Crowfield Village Hall, Crowfield, Suffolk

Lichens are neglected biodiversity.  Despite their ecological significance, dazzling variety and strange beauty, they’re easily overlooked.  But these tiny creatures contain secrets!  And microscopes can help to reveal them.

Anyone can learn how to appreciate lichens using microscopes.  Seeing a lichen under a stereomicroscope for the first time is like descending to the surface of a new planet.  And examining lichen sections at high magnification puts the lichen symbiosis on show: a partnership between completely different organisms that’s unique on Earth.

This one-day workshop will introduce participants to lichens and lichen microscopy.  After an overview of these compelling life-forms, we’ll go outside to collect samples, which we’ll then prepare for examination.  No familiarity with lichens is presumed.  Experience with microscopes will be helpful, but the Anglian Microscopy Group warmly welcomes beginners!

Participants should bring hand-lenses, as well as stereomicroscopes and compound microscopes if possible.  Some microscopes will be available to borrow, and other materials and equipment will be provided.

Join us for a close-up look at the fascinating world of lichens.  You’ll never see them in the same way again!

LICHEN ETHICS AND SAFETY

The field notes and lab notes for various lichen species on this website refer to special field-lichenological techniques. Examples include collecting lichens in the field, testing lichens with chemicals and ultraviolet light, and dissecting lichens with razors or other sharp tools.

These and other field-lichenological techniques require special knowledge and experience. They also demand an ethics of respect for lichens and other wildlife, for conservationally significant species and sites, and for land and landowners.

You should not attempt any of these techniques if you lack the necessary knowledge, experience or ethical sense. You should also take all relevant safety precautions. More information about field-lichenological safety and ethics is available from the British Lichen Society .
