Everything about Asero Rubra totally explained
Aseroë rubra, commonly known as the
anemone stinkhorn and
sea anemone fungus, is a common and widespread Australian
basidiomycete fungus recognizable for its foul odour of carrion and its
anemone shape when mature. Found in gardens on
mulch and in grassy areas, it resembles a red star-shaped structure covered in brownish slime on a white stalk. It attracts flies, which spread its
spores.
Taxonomy
The first native Australian fungus to be formally described,
Aseroë rubra was collected in 1800 in southern
Tasmania and named by the French botanist
Jacques Labillardière. The
scientific name is derived from the
Ancient Greek words
Asē/αση 'disgust' and
roē/ροη 'juice', and the
Latin ruber 'red'. It is a member of the stinkhorn family
Phallaceae though has been placed by some
mycologists in a separate family Clathraceae. Like them it bears its spores in a brownish slime which smells of feces or carrion and attracts flies, which spread the spores.
Description
It begins as a partly buried whitish egg-shaped structure 3 cm (1¼ in) in diameter, which bursts open as a hollow white stalk with reddish arms erupts and grows to a height of 10 cm (4 in). It matures into a reddish star-shaped structure with six to ten arms up to 3.5 cm (1½ in) long radiating from the central area. These arms are bifid (deeply divided into two limbs). The top of the fungus is covered with dark olive-brown slime or
gleba, which smells of rotting meat. There is a cup-shaped
volva at the base that's the remnants of the original egg.
Distribution and habitat
This fairly common fungus is widely distributed in Australia from southeastern
Queensland through
New South Wales and eastern
Victoria and Tasmania. It is also found across the islands in the
Pacific Ocean. A
saprotroph, it's found on woodchips and mulch and is common in gardens and
amenities plantings. it also occurs in alpine grasslands and woodlands. and later in
California in North America.
