19th February 2016, 19:30 to 21st February 2016, 16:00


Event Description:

Friday 19th to Sunday 21st February 2016

Location: Compton Martin, Bristol BS40 6JN.

Please note for logistical reasons, the Workshop will not be located in Bristol University as in previous years.

Host - David Hill

Tutors - Brian Coppins, David Hill and Mark Powell

This workshop will be based on the less used stains, tests, features and techniques helpful in lichen identification. There are quite a few tests for features in apothecial sections like sedifolia grey, HNO3 reactions, crystal tests for lecanoric/gyrophoric acids. Not all the colour changes in for example apothecial sections that are described in keys and descriptions are correctly observed, especially if one does not know exactly what to look for e.g. how much does the colour actually change. Additionally there are the less obvious spore characters and anatomical characters e.g. tissue types such as in cortex of Physciaceae and exciples of Collema and epinecral layers.

Costs
There is a charge of £50 per attendee to cover part of the cost of using the laboratory, the balance of the cost is being subsidised by the BLS.
