A New Tropical Species of Lycoperdon Subgenus Morganella (Agaricales, Basidiomycota) From Yunnan Province, China

Two specimens of Lycoperdon were collected in 2012 and 2013 during surveys conducted in evergreen broadleaf forests of Xishuangbanna, Yunnan Province, China. Macro- and micromorphological characteristics, together with analyses of combined ITS and LSU sequence data, showed that five specimens represent a single new species and is thus named as Lycoperdon mengsongense. The new species is distinguished from the known taxa in Lycoperdon by its greyish white to dark grey exoperidium covered by minute and blackish grey granules, smooth to wrinkled endoperidium, nonchambered subgleba and echinate basidiospores. Comprehensive morphological descriptions, color photographs of macro- and micro- characteristics and a phylogenetic tree to show the placement of the new species are provided. In addition, the new species is compared with closely related taxa in Lycoperdon subgenus Morganella.
