Marasmiellus ramealis - Twig Parachute

The closer you look at fungi the more you see; and the more you look closely at tree trunks and branches the more fungi you see. Some little mushrooms are so tiny that they are often overlooked or assumed to be some of the numerous blob-like ascomycetes of millimetric dimensions. Many of the tiniest cap-and-stem mushrooms fruit on dead twigs - even those attached to living trees - and so it’s important to look up as well as down when wandering through woodlands in search of new finds.

Marasmiellus ramealis is a little white parachute-like mushroom that often grows at or above head height, first appearing in springtime and recurring throughout summer and autumn on twigs and small branches of conifers and deciduous broadleaf trees. (It is also a common sight on dead bramble stems.)

Very common throughout Britain and Ireland, the Twig Parachute is also common and abundant in northern and central mainland Europe, becoming less evident in the Mediterranean region.

Taxonomic history

This mushroom was described in 1788 by the French mycologist Jean Baptiste Francois (Pierre) Bulliard, who named it Agaricus ramealis. (In the early days of fungal taxonomy, most of the gilled mushrooms were included initially in a huge genus Agaricus; later many new genera were erected into which the majority of species were transferred, so that nowadays the genus Agaricus is rather more manageable!) It was the German-born mycologist Rolf Singer who, in 1946, transferred this species to its present genus, thus establishing its currently-accepted scientific name Marasmiellus ramealis.

Synonyms of Marasmiellus ramealis include Agaricus ramealis Bull., Agaricus amadelphus Bull., Gymnopus ramealis (Bull.) Gray, Marasmius amadelphus (Bull.) Fr., Marasmius ramealis (Bull.) Fr., Marasmiellus amadelphus (Bull.) M.M. Moser, and Micromphale rameale (Bull.) Kühner.


The genus name Marasmius comes from the Greek word marasmos, meaning 'drying out'. Elias Magnus Fries, who separated the Marasmius genus from the similar white-spored Collybia fungi, used as a key differentiating factor the ability of Marasmius mushrooms to recover if rehydrated after drying out.

Fries called this characteristic 'marescence'. Fungi such as the Twig Parachute are placed in the genus Marasmiellus because they are 'like Marasmius species but even smaller'.

The origin of the specific epithet ramealis is implicit in the prefix ram- meaning branch. Thus the tendency of the Twig Parachute to grow on dead twigs and small dead branches is reflected in the name ramealis.
