Etymology –
The term Abortiporus comes from the Latin “abortus”, which means “prematurely terminated” or “failed”, and “porus”, which refers to the pores present on the surface of the mushrooms. The term to describe mushrooms that exhibit abnormal growth or irregular shape.
The specific epithet biennis derives from the Latin and means “bipenne” or “two years old”. This reference to the mushroom’s life cycle indicates that the mushroom produces fruit for two consecutive years before dying.
Geographic Distribution and Habitat –
Abortiporus biennis is a saprophytic fungus that bears fruit in broad-leaved woods, rarely conifers, on woody residues or on the ground near trunks, in the period from spring to autumn.
Recognition –
Abortiporus biennis is a mushroom with a cap of diameter between 15 and 20 cm, from sessile to stipitate divided into many lobes, reniform, semicircular or irregular, sometimes zoned, velvety, almost spongy on the surface, whitish with ocher-coloured spots brownish. During growth, this fungus tends to engulf grass or other plants.
The pores are unequal, lacerated, denticulate, labyrinth-shaped, whitish, they stain yellowish-pink to the touch, 1-4 per mm. In young specimens they may have reddish droplets due to exudation.
The tubules are 6 mm long.
The stem is frequently absent or poorly defined, when present it is up to 6 cm long, whitish in colour, velvety.
The flesh is leathery, fibrous, spongy in the upper part of the cap, white to pinkish in colour; exudes pink liquid when pressed.
Under the microscope, white spores can be seen en masse, 5-8 x 3-5 µm, smooth, ellipsoidal, non-amyloid.
Cystidia are globular in shape (gloeocystidia), from infrequent to numerous, of various shapes and up to 75 µm long.
Cultivation –
Abortiporus biennis is a parasitic-saprophytic species, lignicolous or semi-terricolous, which grows at the base of deciduous trees especially in tree-lined avenues and in city parks.
In nature it grows in the woods on wood residues or on the ground near the trunks, in the spring-summer-early autumn period.
Its characteristic is the tendency to engulf grass or other plants during its development.
Due to its null edible value, its cultivation is of no importance.
Customs and Traditions –
Abortiporus biennis is a parasitic-saprophytic species that grows mainly on broad-leaved trees, on woody residues or on the ground near trunks.
This fungus plays an important role in decomposing the lignin and organic matter of many woody parts.
It has no edibility value.
Method of Preparation –
Abortiporus biennis has no edible value.
