Geastrumsuae sp. nov. (Geastraceae, Basidiomycota) a new species from Yunnan Province, China.

ABSTRACT

Background: Geastrum is the largest genus of Geastraceae and is widely distributed all over the world. Four specimens which belong to Geastrum were collected during our scientific expedition to Cangshan Mountain, Yunnan, China. Based on morphological characteristics and phylogenetic analysis, a new species was introduced. New information Geastrumsuae is characterised by its large basidiomata (height 35-70 mm, diameter 18-37 mm) with long stipe (height 10-45 mm), smooth pink exoperidium and sessile globose endoperidial body. Phylogenetic analysis has been carried out, based on the internal transcribed spacer (ITS) and large subunit ribosomal ribonucleic acid (nrLSU) sequence data. The illustration and description for the new taxa are provided.
