Estimates of global fungal diversity have varied widely, suggesting a range from fewer than one million to over 10 million species, with each of the estimates drawing data from various criteria. In 2022, Fungal Diversity published a special issue on fungal numbers. It had been hoped that the editorial would provide a more accurate account of the numbers of fungi. Instead, it was concluded that this was not possible based on present evidence and, some of the data necessary for accurate assessments was put forward, and the present paper expands on this short article. The review first looks at estimates of fungal numbers and what these estimates are based on. It then presents future research needs that will help us to gain a more accurate estimate of fungal numbers. This includes work that needs to be done in tropical rainforests, where the greatest diversity is expected, where whole rainforests, canopy diversity, and palm fungi are addressed. Case studies for lichens and associated fungi, soil and litter fungi, evidence from particle filtration, freshwater fungi, marine fungi, mushrooms, and yeasts will also be given. Once we have such information, we can obtain a more accurate estimate of fungal numbers.

对全球真菌多样性的估计差异很大，表明物种数量从不到 100 万种到超过 1000 万种不等，每个估计都从不同的标准中提取数据。2022 年，Fungal Diversity 出版了一期关于真菌数量的特刊。人们曾希望这篇社论能提供更准确的真菌数量说明。相反，根据现有证据得出结论，这是不可能的，并且提出了准确评估所需的一些数据，本文对这篇短文进行了扩展。本综述首先着眼于真菌数量的估计值以及这些估计值的依据。然后，它提出了未来的研究需求，这将有助于我们更准确地估计真菌的数量。这包括需要在热带雨林中进行的工作，那里预计会有最大的多样性，整个热带雨林、树冠多样性和棕榈真菌都得到解决。还将提供地衣和相关真菌、土壤和凋落物真菌的案例研究、颗粒过滤、淡水真菌、海洋真菌、蘑菇和酵母的证据。一旦我们有了这些信息，我们就可以获得更准确的真菌数量估计。
