Notes: Marasmius guyanensis firstly described by Montagne from French
Guiana (fide Singer, 1976). It is apparently a widespread species throughout
tropical Central and South America (Pegler, 1983) and Asia (Corner, 1996).
This species is easily distingushed by having a small, orange pileus with dark papilla at the center, a presence of collarium, and basidiospores 12-13.6 x 4
μm and it is abundant in research sites.
