Marasmius pulcherripes J. S. Oliveira & Moncalvo
No full textSeries Pulcherripes J.S. Oliveira & Moncalvo Persoonia 44: 274 (Oliveira et al. 2020). Basidiomata marasmioid (umbrella-like), small- to medium-sized. Pileus membranous, campanulate to convex, smooth to shal- lowly sulcate, papillate (1.4-33 mm diam). Lamellae distant to subdistant. Stipe thin-cylindrical, dark-coloured, with a scarce basal mycelium. Basidiospores medium-sized, oblong (11-17 µm long, xm = 12.5- 15.3 µm, Qm = 3.1-4.2). Pleurocystidia present (not clear in some cases), small- to medium-sized (up to 65 µm long). Pileipellis composed of Siccus-type broom cells. Habit solitary to gregarious, on dead, eudicotyledonous leaves and twigs. TYPE SPECIES. — Marasmius pulcherripes. REMARKS Marasmius pulcherripes was originally described from United States. Some strains determined after this species from Northwest Arkansas (MT032485) and Boston Harbor Islands (MF161270; Haelewaters et al. 2018), United States, branched in clade Pulcherripes (Fig. 1). This placement indicates the plausibility of the series.Published as part of S, Jadson José, Oliveira, ouza de, Capelari, Marina, Margaritescu, Simona & Moncalvo, Jean-Marc, 2022, Disentangling cryptic species in the Marasmius haematocephalus (Mont.)
