Abstract

Two new boletes, viz. Retiboletus nigrogriseus and Tengioboletus fujianensis are described based on morphological and molecular evidence. Retiboletus nigrogriseus is characterized by a black pileus when young, gray when old, context and hymenophore staining brownish to fuliginous when injured, black, reticulate stipe with a white basal mycelium, and a subcutis pileipellis composed of uninflated hyphae with cystidioid terminal cells; T. fujianensis is characterized by a large-sized basidioma, brown to reddish brown pileus, reticulate stipe, and a trichodermal pileipellis composed of uninflated hyphae with cystidioid terminal cells. A detailed description, color photos of fresh basidiomata and line drawings of microstructures of the two new boletes are presented.
