Tuber microverrucosum and T. huizeanum two new species from China with reticulate ascospores

Two new species of Tuber are described and illustrated. Tuber microverrucosum is recognized by its brown verrucose ascomata, blackish gleba, and broadly ellipsoid to subglobose ascospores with a large-meshed regular reticulum. Tuber huizeanum is diagnosed by its brown glabrous ascomata, brown gleba, and broadly ellipsoid ascospores with a regular reticulum. Molecular phylogenetic analysis supports the erection of the two new species.
