Campanophyllum microsporum (Agaricales, Agaricomycetes), Calocera multiramosa, and Dacrymyces naematelioides (Dacrymycetales, Dacrymycetes), three new species from Yunnan Province, southwestern China
Three new species belonging to Basidiomycota from southwestern China are described based on morphological and molecular data. Campanophyllum microsporum is morphologically characterized by dorsally pseudostipitate, pale orange to brownish orange pileus, excentric to lateral pseudostipe, crowded lamellae, cylindrical-ellipsoid basidiospores 3.0–4.2 × 1.7–2.2 µm, narrowly clavate to clavate basidia 14.5–23.0 × 3.0–4.2 µm, and cylindrical to clavate cheilocystidia 22.0–55.0 × 5.0–10.8 µm. Calocera multiramosa is morphologically characterized by stipitate, yellowish to orange, dendroid, and dichotomously branched basidiomata, cylindrical to clavate basidia 36.5–52.5 × 3.8–6.1 µm, navicular or reniform, 1–5-septate mature basidiospores 10.4–16.7 × 5.2–7.4 µm. Dacrymyces naematelioides is morphologically characterized by stipitate and cerebriform, orange to light brown basidiomata, cylindrical to clavate, smooth or roughened basidia 38.5–79.5 × 6.5–10.6 µm, broadly and elliptic-fusiform, 7-septate mature basidiospores 18.5–28.6 × 8.9–13.8 µm. These three new species are supported by the phylogenetic analyses using maximum likelihood (ML) and Bayesian inference (BI) analyses with combined nuclear ribosomal DNA (rDNA) internal transcribed spacer (ITS) and large ribosomal subunit (LSU) sequences. Full descriptions and photographs of these new species are provided.
