Members of the basidiomycete genus Hygrocybe are largely restricted to
nutrient-poor grasslands and are of significant conservation interest in the
UK context. These species are all uncultured and virtually nothing is known
about their functional ecology. It is proposed to use species-specific PCR
probes to measure the vertical distribution in soil of mycelia. Detailed
mapping of fruitbodies (FBs) over two autumns will permit the effect on FB
production (at least 10 spp. occur at the site) of the various plot treatments
and local soil variations at Sourhope to be quantified. 15N-enriched plant litter buried around
mapped Hygrocybe fairy rings will permit tracking of isotope
enrichment in subsequently formed FBs. Co-ordination with 13CO2
pulses in 2002 will also allow isotope tracking over shorter periods.
Natural abundance of these isotopes in FBs will also be measured.
