The final year of the Lost and Found Fungi project

The Lost and Found Fungi project helps amateur mycologists discover the UK’s most rarely seen fungal treasures. As we reach the final year of recording we assess the project’s successes so far.

Fungi

Raising the profile of rare or potentially under-recorded fungi

The Lost and Found Fungi (LAFF) project is a volunteer-based conservation project which started in 2014. It aims to increase awareness, recording, and knowledge of 100 rarely-recorded fungi in the UK (LAFF100). At the same time, we hope to promote knowledge-sharing, skills, and engagement with rarely recorded species amongst the UK’s amateur fungus recording community. 

The list of 100 species contains something for everyone, including distinctive mushrooms, puffballs, brackets, smut and rust fungi, tiny cup fungi, leaf-spot parasites, lichenised fungi, and more. Each fungus has its own strangely beautiful fruiting bodies and mysterious ecology. The species have also been selected for many reasons, some haven’t been recorded in the UK for over 50 years, or are known from only a few sites. There are species new to science; new (potentially invasive) arrivals; species of current conservation concern; and species restricted to rare plants and habitats. They can be found in many different habitats, from dune systems to mountain plateaus, bogs, calcareous marshes, ancient woodland, orchards, or urban areas and gardens.

Over the past three and a half years we’ve been encouraging people to look out for these species in their areas, to check sites of historical records, and survey known sites. We’ve also been joining recording groups and individuals in their surveys across the UK. 

    Volunteers and contributors are vital to the project

    The project involves encouraging and supporting citizen scientists in the hunt for some of our most rarely seen fungal treasures across the UK. Engaging with the public and acting as a friendly and accessible mycological resource to help with advice and identification has been essential to every aspect of the project.

    Engagement has been achieved partly by developing a website and associated Facebook and Twitter feeds as well as working directly with interested people through mentoring, training and joining expeditions.

    Recording results so far

    The records of fungi collected since July 2014 now stands at around 1000 new records of 65 species. Gathered over three and a half years, the records will help establish a robust baseline distribution for the project, increase our knowledge of their identities and ecology, and underpin forthcoming Red List conservation assessments.

    Visits to fungus recording groups

    Field trips are some of the most enjoyable parts of the project, and throughout the project we’ve been privileged to visit recording groups across England, Wales, Scotland, and Northern Ireland. Most recently we visited the Cornwall Fungus Recording Group. As the ‘Beast from the East’ settled upon the country, we faced challenging and frosty fungus-hunting conditions during the first three days of our visit. Thankfully, expert guidance from our hosts ensured that we found plenty of fungi for a two-day microscope workshop at the end of the week, as well as successfully surveying for several project-specific species. Unfortunately the snow soon descended, cutting our time and number of participants for microscope and identification training in half. Nevertheless this proved a rewarding and enjoyable week with some interesting finds. 

      Future work, and stories yet to be told

      As the project approaches its final year of funding we plan to make the most of our last complete foraying year. We are consolidating existing data for publication and distribution; and working through our backlog of rarely recorded ‘bycatch’ specimens sent into the project. We’re also exploring options and resources to help encourage further work after the project ends.

      Success stories

      Each species within the project has its own story, and we’ve seen these develop during the Lost and Found Fungi project:

      • Species not seen for over 50 or even 100 years in the UK have been rediscovered, such as Sporomega degenerans, an immersed discomycete fruiting on dead stems of Vaccinium uliginosum (bog bilberry); and Ustanciosporium gigantosporum and U. majus, smut fungi in the ovaries of Rhynchospora alba (white beak sedge).
      • Some ‘rare’ species now appear much more common than previously thought, such as Puccinia cladii, a rust fungus on leaves of Cladium mariscus, and Mollisia fuscoparaphysata, a tiny cup fungus on leaves of Trichophorum (deer grass).
      • Many species still seem to be rare and vulnerable, but their populations appear far healthier than past records suggest, such as the marsh honey fungus Armillaria ectypa, and the fen puffball Bovista paludosa.
      • The arboriculture community has helped find fungi associated with veteran or old trees, resulting in many new records of Podoscypha multizonata (zoned rosette), and Sarcodontia crocea, a pineapple-scented toothy crust on old apple trees.
      • We’ve described new species, such as the new marram oyster Hohenbuehelia bonii, and a new big blue pinkgill Entoloma atromadidum (previously considered to be Entoloma bloxamii), redetermining a sizable proportion of Kew’s collections of this group in the process.
      • We’ve encouraged and supported amateur taxonomic work and recording work, resulting in publications about rarely recorded Anthracoidea smuts, and the cryptic Microglossum earthtongue complex in Wales.
