摘要
Cystolepiota Singer is rarely studied in Southeast Asia; here, we survey and describe three new species of Cystolepiota from tropical Laos and Thailand. Cystolepiota pyramidalis is related to C. fumosifolia (Murrill) Vellinga and C. pseudofumosifolia M.L. Xu & R.L. Zhao, but it is distinguished by pale to pastel yellow lamellae. Second, Cystolepiota thailandica differs from other members in the genus by the greyish-orange granulose or powdery pileus and stipe covering made up of globose to subglobose and sphaeropedunculate elements. Furthermore, Cystolepiota rhodella is characterized by the pink-violet granulose covering of the pileus and stipe and white lamellae with distinctly violet edges. Each species is provided with a full description of the morphological characters, photos in situ, line drawings of the microcharacters, discussion of related and similar species, and molecular data.
