Comparative Fungal Biology

We study the diversity, evolution and ecology of fungi using taxonomy, systematics and molecular approaches.

All life depends on plants and all plants depend on fungi. With their multiple ecological roles as decomposers, symbionts or pathogens, fungi are fundamental to life on Earth. Yet knowledge of fungal biology lags far behind that of plants.  

Kew has a strong track record in fungal diversity research and is home to the largest fungarium in the world, holding over 1.25 million fungal specimens. The Comparative Fungal Biology team combines fundamental taxonomic expertise with molecular approaches and ecological perspectives. Our research ranges from baseline diversity studies in biodiversity hotspots through to reconstructing the Fungal Tree of Life, with a special emphasis on evolution and ecology of lifestyles and symbiotic interactions.  

Symbiotic fungi play a major role in most ecosystems, and we have special expertise in lichens, mycorrhizal fungi, ant-farmed fungi, and endophytic fungi, and use these examples of mutualistic symbiosis as model groups to address broader questions related to determinants of diversity and evolution, community ecology and global change.  

Our projects include fieldwork in a wide variety of ecosystems, from tropical areas to alpine ecosystems and temperate and boreal forests. We use different techniques including microscopy, fungal culturing, statistics, phylogenetics and phylogenomics, to address our research questions.
