毒鹿花菌——一个发现于中国的毒蘑菇新种

基于形态学和系统发育研究结果,本研究报道在中国华中和西南地区发现的一个隶属于鹿花菌属鹿花菌亚属的有毒新种——毒鹿花菌。该种在形态上与鹿花菌Gyromitra esculenta十分相似,但毒鹿花菌的囊盘被分化较为明显,外表面几乎由一层栅状细胞排列而成,而鹿花菌的囊盘被基本没有分化。此外,毒鹿花菌通常具有更长的菌柄并生于阔叶林地上。为了准确理解鹿花菌的物种概念,本研究指定了一份采自法国的标本（即HMAS 21460）作为该种的附加模式。

Gyromitra venenata,a new poisonous species discovered from China

Gyromitra venenata, a new poisonous species belonging to Gyromitra subgenus Gyromitra, is described from central and southwestern China on the basis of morphological data and phylogenetic evidence. Morphologically, the new species is very similar to G. esculenta. Nevertheless, G. venenata has well-differentiated ectal excipulum with a layer of palisade cells. The ectal excipulum of G. esculenta is not well differentiated from medullary excipulum. Moreover, the new species usually possesses longer stipe and is found on the ground in broad-leaved forests. In order to interpret the concept of G. esculenta consistently, the collection HMAS 21460, collected from France, is designated as an epitype of G. esculenta.
