This is particularly true for the 20 vast part of soil biodiversity, which rarely can be observed directly. 21 Metabarcoding of DNA extracted from the environment (eDNA) has become 22 state-of-the-art in assessing soil biodiversity. Also for fungal community 23 profiling eDNA is seen as an attractive alternative to classical surveying based 24 on fruitbodies. However, it is unknown whether eDNA-metabarcoding 25 provides a representative sample of fungal diversity and census of threatened 1 bioRxiv preprint doi: https://doi.org/10.1101/493312; this version posted December 13, 2018.
