Four New Species of <i>Deconica</i> (Strophariaceae, Agaricales) from Subtropical Regions of China
<i>Deconica</i> is a relatively small genus, with only 90 names recorded in previous research. In this study, four new species of <i>Deconica</i> have been identified based on morphological and phylogenetic evidence from subtropical regions of China. This represents the first...

| description | <i>Deconica</i> is a relatively small genus, with only 90 names recorded in previous research. In this study, four new species of <i>Deconica</i> have been identified based on morphological and phylogenetic evidence from subtropical regions of China. This represents the first discovery of new species of <i>Deconica</i> in China. Morphologically, <i>D</i>. <i>austrosinensis</i> is characterized by medium-sized spores that are elliptical to elongated-ellipsoid in face view, and fusiform to sublageniform and slightly thick-walled pleurocystidia; <i>D</i>. <i>furfuracea</i> 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; <i>D</i>. <i>fuscobrunnea</i> 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; <i>D</i>. <i>ovispora</i> is distinguished from other <i>Deconica</i> 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. |
