Description:Phellinus contiguus (Fr.) Pat., Ess. Tax. p. 97, 1900. - Polyporus contiguus Fr., Syst. Mycol. 1:378, 1821.
Basidiocarps perennial, resupinate, adnate, mostly elongated and effused, up to 20 cm long, 5 cm wide and up to 1 cm thick, smooth and even or nodulose and undulated on oblique substrates with smooth sterile areas in between fertile poroid areas, spongy when fresh, hard when dry; pore surface reddish to umber brown, often with a grayish pruina, pores angular, on the average 2-3 per mm, often somewhat sinuous and irregular, especially on oblique substrates and then often split in front, up to 1 mm wide, along the margin often deeply split into a labyrinthine to irpicoid configuration; margin mostly narrow, rusty brown and finely floccose, disappearing with age; context very thin, rusty brown, up to 1 mm thick; tube layers indistinctly stratified, up to 10 mm thick Hyphal system dimitic; generative hyphae thin-walled, hyaline, simple septate, 2-3.5 µm in diam, slightly thick-walled and pale yellowish in the subiculum and the floccose margin, skeletal hyphae yellowish to rusty brown, straight, thick-walled, non-septate 35 µm in diam, with a distinct lumen.
Tramal setae acute, tapering from the base, thick-walled and straight, dark brown to light yellowish in the tips, scattered and not always easy to find, occurring in the floccose margin and in the trama, 40-120 x 5-12 µm.
Hymenial setae very abundant, subulate, thick-walled, dark brown, with a bent base, either terminal or more rarely lateral from generative hyphae, often with a bulbous base, projecting 15-45 µm above the hymenium, (35-)40-95) x 6-10 µm.
Cystidioles abundant, mostly as hyphal ends, partly embedded in the hymenium, partly projecting above it, but also as ventricose organs with a tube like upper part projecting above the hymenium, hyaline, thin-walled.
Basidia clavate, 4-sterigmate, 10-16 x 5-7 µm, simple-septate at the base. Basidiospores oblong to cylindric, hyaline, thin-walled, smooth, with a large oildrop, negative in Melzer's reagent, 5-7 x 3-3.5 µm.
Type of rot. White rot in dead hardwoods.
Cultural characteristics. See Stalpers 1978.
Sexuality. Unknown.
Substrata. Rarely on conifers like Abies, Larix and Picea, usually on hardwoods such
as Acacia, Acer, Alnus, Arbutus, Berberis, Betula, Catalpa, Clematis, Cornus, Cotinus, Cratageus, Eucalyptus, Euonymus, Fagus, Fraxinus, Hippophäe, Juglans, Laburnum, Liguster, Lonicera, Magnolia, Phillyrea, Populus, Prunus, Pyrus, Rhamnus, Robinia, Rosmarinus, Rosa, Quercus, Salix, Sambucus, Sorbus, Syringa, Tilia and Ulmus.
Distribution. P. contiguus is widespread in warmer parts of Europe and have a distribution similar to that of Quercus, although it does not grow as far north as this tree. Throughout the tropical zone.
