Three new Xylaria species (Xylariaceae, Xylariales) on fallen leaves from Hainan Tropical Rainforest National Park.


ABSTRACT: Three new species of Xylaria on fallen leaves in Hainan Province of China are described and illustrated, based on morphological and molecular evidence. Xylariahedyosmicola is found on fallen leaves of Hedyosmumorientale and featured by thread-like stromata with a long sterile filiform apex. Phylogenetically, X.hedyosmicola is closely related to an undescribed Xylaria sp. from Hawaii Island, USA and morphologically similar to X.vagans. Xylarialindericola is found on fallen leaves of Linderarobusta and characterised by its subglobose stromata and a long filiform stipe. It is phylogenetically closely related to X.siculaf.major. Xylariapolysporicola is found on fallen leaves of Polysporahainanensis, it is distinguished by upright or prostrate stromata and ascospores sometimes with a slimy sheath or non-cellular appendages. Xylariapolysporicola is phylogenetically closely related to X.amphithele and X.ficicola. An identification key to the ten species on fallen leaves in China is given.
