Based on morphological and molecular phylogenetic analyses, two new species, Tuber shidianense and T. calosporum , are described from southwest China. They are clearly different from any other taxon in the genus Tuber . Tuber shidianense belongs to the Puberulum group. It is characterized by whitish ascomata, pseudoparenchymatous peridium and globose ascospores with deep alveolar ornamentation. Tuber calosporum belongs to the Macrosporum group. It is recognized by yellow and brown ascomata, prosenchymatous peridium and large elliptic ascospores with low alveolate wall. Phylogenetic relationships and morphological differences between these two new species and their related species are discussed. [ABSTRACT FROM AUTHOR]

Cantharellus hygrophorus is described and illustrated from tropical Yunnan, China. It is characterized by its medium to large, fleshy fruitbodies, the deep orange-red color of pileus and part of the stipe, the yellow-orange hymenophore composed of well-developed gill folds, a pileipellis of suberect hyphal extremities and absence of clamps. These characters place it in Cantharellus subg. Afrocantharellus sect. Cutirellus as a look-alike of the tropical African C. splendens. Both morphological features as well as a phylogenetic analysis of nLSU sequences argue strongly against the recognition of Afrocantharellus as a separate genus, which is here considered a later synonym of Cantharellus.
