Marasmius rotula
, the pinwheel mushroom, is a fungus in the family
Marasmiaceae
. Widespread in the Northern Hemisphere, it was first
described
scientifically in 1772 by
Giovanni Antonio Scopoli
. The mushrooms are characterized by thin whitish
caps
up to 2.0 cm (0.8 in) wide that are sunken in the center and pleated with scalloped margins. The wiry black hollow
stalks
measure up to 8.0 cm (3.1 in) long by 1.5 mm (0.06 in) thick. On the underside of the caps are widely spaced white
gills
, attached to a collar encircling the stalk. The mushrooms grow in groups or clusters on decaying wood such as moss-covered logs and stumps.
Spore
release is dependent upon sufficient moisture. Dried mushrooms may revive after rehydrating and release spores for up to three weeks, much longer than most gilled mushrooms. Although the mushrooms are not generally considered
edible
, they produce a unique
peroxidase
enzyme that is attracting research interest for use in
bioengineering
applications. (

An
oblique shock
is a
shock wave
that, unlike a normal shock, is inclined with respect to the direction of incoming air. It occurs when a supersonic flow encounters a corner that effectively turns the flow into itself and compresses. This photograph shows an oblique shock at the nose of a
Northrop T-38 Talon
aircraft, made visible through
Schlieren photography
.
