Introduced by Lukáš Picek et al. in Danish Fungi 2020 -- Not Just Another Image Recognition Dataset18 Mar 2021 archive 2025-07-28

Danish Fungi 2020 (DF20) is a fine-grained dataset and benchmark. The dataset, constructed from observations submitted to the Danish Fungal Atlas, is unique in its taxonomy-accurate class labels, small number of errors, highly unbalanced long-tailed class distribution, rich observation metadata, and well-defined class hierarchy. DF20 has zero overlap with ImageNet, allowing unbiased comparison of models fine-tuned from publicly available ImageNet checkpoints.

The dataset has 1,604 different classes, with 248,466 training images and 27,608 test images.
