Fungi foray: A 4 hour foray into one of Londons parks or woodlands in search of mushrooms & toadstools.  The foray begins with a short talk, giving an overview of the mushrooms & toadstools in England, highlighting diffferences between some of the more frequent edible and toxic species.  Most species found during the foray will be identified to species if possible, if not, then to genus.  All species will be noted and a species list compiled and made available to the managing body of the area forayed and to the those attending.   Some of the more unusual species will be collected, dried, written up and deposited at the Royal Botanic Gardens Kew, fungi herbarium.  A greater understanding of distribution patterns and important information for local bio-diversity action plans is the reward for providing these 'voucher specimens' and species lists.  Those attending the forays will be allowed to collect enough edible mushrooms for their own personal consumption.
