中国蜡伞科云片衣属和地衣小荷叶属担子地衣(英文)

Another lineage of basidiolichen in China,the genera Dictyonema and Lichenomphalia(Agaricales:Hygrophoraceae)

本文报道了中国蜡伞科担子地衣2个属4个种,其中包含1个新种和1个中国新记录种,新种为云南云片衣Dictyonema yunnanum,新记录种即为亚洲新记录种,灰盖地衣小荷叶Lichenomphalia velutina。云南云片衣的主要鉴别特征为:地衣体呈蓝绿色纤维状,纤维尖端白色至银白色,直立。本文对所研究的物种进行了详细形态描述并给出了每种的外形特征图,提供了中国蜡伞科担子地衣已知物种检索表。

Several specimens of basidiolichen belonging to the Hygrophoraceae were collected as part of the China lichen mycota. These belong to four species in two genera, Dictyonema and Lichenomphalia. Dictyonema yunnanum is described as new and Lichenomphalia velutina is newly recorded for Asia based on inferences from morphological, chemical and phylogenetic analysis. Dictyonema yunnanum is characterized by the dark aeruginous blue to black filamentous, ascending to erect, micro-fruticulose thallus. The species of lichenized Hygrophoraceae occurring in China are described and a key to distinguish them is presented.
