Series 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.
