Description

Marasmius bulliardii is an inedible species of Fungi in the family Marasmiaceae. The cap of Marasmius bulliardii is frequently colored orange, white, and yellow. The color of the flesh is often brown, white, and yellow. The gills of Marasmius bulliardii are regularly colored white. The stem is often colored brown. It is a common mushroom that grows mainly on forest soils. The cap is shaped funnel-like, sulcate, and umbrella-like. The fruit body is bleaching. The stem is fibrous.

Widespread in many parts of western and northern mainland Europe, where it is generally an uncommon find but may be locally abundant.

Common names: Marasme de Bulliard (French).

Mushroom Identification

1. Cap

   Off-white to pale cream tinged with buff or ochre and 3-10mm in diameter, the parachute-shaped caps of Marasmius bulliardii have deeply-grooved margins. There is nearly always a distinctive dark-brown papilla (nipple) in the center of each umbilicate cap.

2. Gills

   The very distant gills of this parachute mushroom are connected to a collar around the cap stem.

3. Stem

   Near its apex the stem is concolorous, becoming dark brown and then black right down to the base; 0.1 to 0.5mm diameter and 2 to 6cm long. There is no stem ring.

4. Spores

   Ellipsoidal to almost cylindrical, smooth, 7.3-9.5 x 3.2-4.5μm, Q ~ 2.1; hyaline; inamyloid.

5. Spore Print

   White.

6. Odor and Taste

   Not distinctive.

7. Habitat

   Saprobic, usually in groups, on dead leaves of broadleaf deciduous trees, particularly beech; occasionally also on conifer needles

8. Season

   Summer and Autumn.

Look-Alikes

1. Marasmius rotula

   Has a larger fruit bodies, the absence of a tubercle on the cap, and the color of the stem.

2. Marasmius wettsteinii

   Grows in the coniferous forests under spruce and fir. It is distinguished by a paler cap, and rarer plates.

History

This mushroom was described in 1878 by Lucien Quélet, who named it Marasmius bulliardii.

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 drought survival characteristic 'marescence'.

The specific epithet bulliardii honors French mycologist Jean Baptiste Francois Pierre Bulliard.
