Leucangium carthusianum is the European truffle species of the genus, described by the Tulasne brothers in 1862 (as Picoa carthusiana) from France, where it was found under pines. Before 2025 the Oregon black truffle of the Pacific Northwest was also called by this name, but Lemmond et al. (2025) showed that the North American truffle is a genetically distinct species, L. cascadiense, and kept L. carthusianum for the European fungus. It looks similar to the Oregon black truffle.
Little reliable culinary information is published for the European species. Treat it as unknown; do not assume it matches the Oregon black truffle.
Never eat a wild mushroom based on a web page — confirm with an expert.
Mycology is an evolving science: names, classifications and safety information change as research advances. Entries are compiled from cited sources and reviewed, but may be incomplete or out of date — check the sources, and never rely on this library alone to identify or eat a mushroom.
