The proposal of Chinas "One Belt and One Road" foreign development strategy not only provides a new opportunity for the development of Chinas higher vocational colleges, but also makes the development of higher vocational colleges face new challenges. This paper mainly expounds the practical needs of the international development of higher vocational colleges under the background of "One Belt and One Road", analyzes the problems existing in the international development of higher vocational colleges under the background of "One Belt and One Road", and further explores the "Belt and Road" under the background of the international development direction of higher vocational colleges.展开更多

文摘Based on morphology and phylogenetic analyses,a new species,Efibula candidissima,is described from Bawangling,National Park of Hainan Tropical Rainforest.The basidiomata are resupinate,waxy,snow white when fresh,white to cream and soft corky to fragile when dry,with distinct snow white rhizomorph at margin.Hymenophore surface are smooth,and the clamp connections are absent.Ellipsoid to oblong-ellipsoid basidiospores measure 4.8–5.8×3.3–4μm.This species is distributed in tropical forest in southern China.
