Marasmius siccus, or orange pinwheel,[1] is a species of fungus in the Marasmius genus. It is found in Eurasia and eastern North America.
Description
[edit]The small orange mushroom has an umbrella-shaped cap which is 0.5–2.5 centimetres (1⁄4–1 in) wide. The gills are whitish. The tough shiny bare stem is pale at the top but reddish brown below, and 3–7 cm (1+1⁄4–2+3⁄4 in) tall.[2][3][4][5]
Microscopic details
[edit]At a microscopic level, the club-shaped spores are very long and thin, being roughly 19 μm by 4 μm. The distinctive cheilocystidia are broadly club-shaped with finger-like protrusions at the far end. Such cells also sometimes occur in other related mushrooms and they are known as "broom cells of the siccus type".[4][5]
Similar species
[edit]M. fulvoferrugineus and M. pulcherripes are similar, but the caps are more pink.[6]
Habitat and distribution
[edit]This mushroom is found in hardwood forests. It is distributed in northern Europe and Asia,[4][5] and in North America from July to September,[6] from the Rocky Mountains to the Appalachians.[7]
Edibility
[edit]Although nonpoisonous, the mushrooms are too small to be considered worthwhile as food.[8]
