ABSTRACT
Note: Predictions are made from the number of fungi already known (A), modified by the average number of fungi known to associate with plants (B), this value extrapolated for A using the plant species in the British Isles (C), modified for a figure from alpine communities (D), and then all these values are averaged (E). Conversions and extrapolations F to H are based on predicted unknown substrates for fungi yet to be discovered, the fact that some anamorphs and teleomorphs will be found to be the same species, and extrapolating to the potential number of insects yet to be discovered that will bear fungi. Source: Data from Hawksworth (1991).
