Deconica is a relatively small genus, with only 90 names recorded in previous research. In this study, four new species of Deconica have been identified based on morphological and phylogenetic evidence from subtropical regions of China. This represents the first discovery of new species of Deconica in China. Morphologically, D. austrosinensis is characterized by medium-sized spores that are elliptical to elongated-ellipsoid in face view, and fusiform to sublageniform and slightly thick-walled pleurocystidia; D. furfuracea is identified by a well-developed and evanescent veil, medium-sized spores that are rhomboid to mitriform in face view, and fusiform to subclavate pleurocystidia that are rare and subacute at apex; D. fuscobrunnea is recognized by dark brown pileus, medium-sized spores that are rhomboid to mitriform in face view, an ixocutis pileipellis, lageniform cheilocystidia with a long neck and lacks pleurocystidia; D. ovispora is distinguished from other Deconica species by medium-sized spores that are ovoid in face view, an ixocutis pileipellis, lageniform cheilocystidia with a long to short neck, and lacks pleurocystidia. Their distinct taxonomic status is confirmed by the positions of the four new species in ITS + LSU phylogenetic trees. Detailed descriptions and morphological photographs of four new species are presented. [ABSTRACT FROM AUTHOR]

Entoloma is a relatively large genus in Agaricales, with a rich diversity of species and a wide distribution. In this study, seven new species of Entoloma belonging to the subgenus Cubospora have been identified based on morphological and phylogenetic evidence from subtropical regions of China. Morphologically, E. excavatum is characterized by the yellow, depressed, estriate pileus and medium-sized basidiospores; E. lacticolor is recognized by the white and papillate pileus, adnexed lamellae, and presence of clamp connections; E. phlebophyllum is identified by the pink-to-maroon and estriate pileus, and lamellae with lateral veins; E. rufomarginatum differs from other cuboid-spored species by the lamellae edge which is red-brown-underlined; E. subcycneum is characterized by the white pileus and carneogriseum-type cheilocystidia; E. submurrayi is recognized by the pileus margin exceeding the lamellae, 2-layered pileipellis with hyphae of different widths, and the presence of clamp connections; E. tomentosum is identified by the tomentose pileus, heterogeneous lamella edge, and versiform cheilocystidia with brown-yellow contents. Their distinct taxonomic status is confirmed by the positions of the seven new species in both the ITS + LSU and 3-locus (LSU, tef-1α, rpb2) phylogenetic trees. Detailed descriptions, color photos, and a key to related species are presented. [ABSTRACT FROM AUTHOR]
