Cite abortiporsu page as: As I have collected it, Abortiporus biennis is usually abortioorus true oddball–a gnarled, messy-looking mass of irregular white pores that exude a reddish juice and bruise reddish brown.

Fresh, young specimens of Abortiporous biennis sometims exude red droplets, suggestive of Hydnellum pecki. Pores decurrent in stipitate specimens, mm broad, angular, becoming labyrinthoid with lacerate mouths, white to buff, when fresh, often bruising or weathering pinkish to reddish-brown, sometimes exuding reddish droplets; tubes colored ahortiporus the pores, up to 5 mm long; pores covering the entire surface in “aberrant fruitings.

Often absent or poorly defined, but when present up to 6 cm long; whitish; velvety.

Phaeolus schweinitiziiwhich also sometimes forms “rosettes” on the ground, is generally larger, has mustard-olive pores nearing maturity, dark-brown when senescent, and saprobic on conifer roots or stumps, not hardwoods.


There bienniis hardly a cap or a stem to speak of, and as it grows it engulfs sticks and blades of grass the way some species of Hydnellum do.

Young Abortiporus biennis in a forest near Dourdan, France. Though Abortiporus biennis is easily recognized without recourse to a microscope, its microscopic features are distinctive and interesting–from its cystidia to the presence of both spores abrtiporus chlamydospores roundish, thick-walled, asexual spores. Despite the common name “Blushing rosette,” which refers to the vinaceous hues seen in many fruitings, the color is actually quite variable, aortiporus from cream, reddish, ochre, to brown.

This ground-dwelling polypore often puzzles collectors with its mixture of “normal” shelving clusters and “aberrant” cauliflower-like fruiting bodies.

These include Polyporus tuberaster whose funnel-shaped, ochre-brown caps are squamulose, not tomentose, and Albatrellus species, abortiporsu can be distinguished by pores that never become labyrinthoid, microscopically by the lack of chlamydospores, and a mycorrhizal habit.

White to pinkish or pale tan; exuding a pinkish juice when squeezed; 2-layered in mature specimens; tough. Often covered with the pore surface, but when abortipofus up to 20 cm across; kidney-shaped to semicircular or irregular in outline; whitish to pale brown or reddish brown; sometimes with concentric zones; finely velvety or fairly smooth.

Whitish, bruising and discoloring reddish or pinkish brown; pores angular to maze-like or irregular, per mm; tubes to 6 mm deep. Fruiting body annual, terrestrial, fan-shaped to infundibuliform, pilei cm broad, often clustered; margin level to uplifted, wavy; upper surface tomentose, white, pinkish, reddish-brown, bienis to ochre-brown, faintly azonate; “aberrant fruitings” also produced, consisting of cauliflower-like masses, the entire surface poroid; context up to 1.

Stipe if present, poorly developed, up to 5 cm long, 3 cm thick, lateral to aboortiporus in attachment, well rooted and incrusted with dirt. A number of terrestrial polypores are similar.

This gnarled form of Abortiporus biennissometimes given the separate species name of ” Abortiporus distortus ,” is apparently the most commonly encountered form of the species, though it does have a more normal looking form with an identifiable cap biennid stem see the illustrations.

Abortiporus – Wikipedia

Solitary or in small groups in soil or grass near hardwood stumps, rarely with conifers; fruiting throughout the year in watered areas, e.

Saprobic on the wood of hardwoods and occasionally conifers; growing alone or gregariously around the bases of stumps and living trees; causing a white rot in deadwood and a white trunk rot in living wood; summer and fall winter and spring in warm coastal areas ; widely distributed in North America. OpenStreetMap – Google Earth. Kuo, To the right is an example which is somewhat more developped. The timestamp is only as accurate as the clock in the camera, and it may be completely wrong.

Heteroporus biennis is a synonym, as is Abortiporus distortus see discussion above.
