This wiki site has been created to provide further information on the diversity of fungi in Sarawak on the island of Borneo.

Our focus is on putatively ectomycorrhizal fungi, namely fleshy terrestrial mushrooms that belong to groups with well-established ectomycorrhizal associations elsewhere (e.g., boletes, chanterelles, amanitas, russulas, etc.), although we also collect more broadly in an attempt to capture as much of the diversity as possible. To date, we have spent most of our time at Gunung Mulu National Park and Batang Ai National Park.

With elevations ranging from sea level to 2,423 m on Gunung Murud, and myriad underlying geological types affecting landscape and soil characteristics (e.g., limestone, alluvial, sandstone, shale, etc.), Sarawak is remarkably rich in habitats. We are targeting collections from many of these habitats, defined primarily by their vegetation types, including lowland mixed dipterocarp (upper left), montane (Fagaceae-dominated) (upper right), kerangas (lower left), and upper montane mossy rhododendron (lower right) forest.

This work has been generously supported through grants from the Bentham-Moxon Trust to BD and Royal Ontario Museum Fieldwork Funds to J-MM. We are very grateful to Sarawak Forestry for providing collecting and export permits. We are also grateful to Brian Clark for allowing us to work at Gunung Mulu National Park. None of this work would be possible without the substantial help from numerous local field assistants, to whom we give our sincerest gratitude.
