Archaeomarasmius

The generic epithet Archaeomarasmius is a combination of the Greek archaeo- meaning "ancient" and "Marasmius", a modern genus which it resembles. The specific epithet "leggetti" was coined by the authors in honor of J.J. Leggett and company, who first discovered the amber nodule and donated it to the American Museum of Natural History (AMNH).

Archaeomarasmius is known from two fruit bodies recovered from amber, one consisting of a complete cap with a broken stem, the other consisting of a fragment of a cap. The cap has a diameter ranging from 3.2 to 6 mm (0.13 to 0.24 in), while the stem is 0.5 mm (0.02 in) thick. Spores were also recovered from the amber, and are broadly ellipsoid to egg-shaped, measuring roughly 7.3 by 4.7 μm.

Archaeomarasmius, which resembles the extant genera Marasmius and Marasmiellus, is inferred to have been saprobic on plant litter or other forest debris.
