Morpho-molecular analysis of two new species and in Agaricales from Mount Tianmu, China.

Two new species of Agaricales, and , are described from Mount Tianmu, Zhejiang Province, Eastern China. Two new species are distinct and monophyletic based on morphology and phylogenetic analyses. differs from other species in that the pileus is brow shallow in the center and stipe with yellowish white fibrils, scatted on litter under coniferous and broad-leaved mixed forest at 1162 m.

[Structure dynamics of communities after cutting along altitude in Mount Tianmu, China].

We examined the dynamics of community structure in forests formed after cutting all at altitude of 480, 580, 700 and 800 m of the Mount Tianmu National Nature Reserve in Zhejiang Province, from 2017 to 2020, using phytocommunity method. Results showed that the total number of plant individuals was 515 belonging to 50 species, 43 genera and 27 families in 2017. After three years, 30 new plant species emerged, belonging to 23 genera and 14 families, and the number of individuals increased by 116.

[Ultrastructural changes of duodenal mucosas and their significance in patients with liver cirrhosis].

Objective: To investigate the ultrastructural changes of duodenal mucosas and their significance in patients with liver cirrhosis (PLC).

Methods: Endoscopic biopsy duodenal mucosa specimens of 60 PLC and 18 healthy volunteers as controls were obtained. Ultrastructural changes of them were studied with transmission electron microscopy.
