试图评估真菌的全球物种丰富度是混淆了几个问题：不确定性的数量描述的物种，不完整的真菌库存，即使在一个高的分类水平，高多样性的未知，往往是小而难以捉摸的类群，高水平的形态保护，和不完整的知识，其生态和地理分布。估计真菌总多样性的两个主要基础是（1）描述的物种数量及其分类结构，和（2）推断种-面积关系。我们认为，知识的真菌分类学和环境采样的真菌都太不完整的方法是可靠的。然而，地球上真菌物种的真实数量很可能是七位数，甚至可能更高一个数量级。(C)2011年由Elsevier Ltd代表英国真菌学会出版。
Attempts to assess fungal global species richness are confounded by several problems: uncertainty about the number of described species, incomplete fungal inventories even at a high taxonomic level, high diversity of unknown, often small and elusive taxa, high levels of morphological conservation, and incomplete knowledge of their ecological and biogeographical distributions. The two main bases for estimating total fungal diversity are (1) the number of described species and their taxonomic structure, and (2) extrapolating species-area relationships. We argue that knowledge of fungal taxonomy and environmental sampling of fungi are both too incomplete for either approach to be reliable. However, it is likely that the true number of fungal species on the planet is a seven-digit number, and may even be an order of magnitude higher.
