Polyporus
Sclerotia - Stielporling ( Polyporus tuberaster )
The Stielporlinge or actual Porlinge ( Polyporus ) are a genus of the family of Stielporlingsverwandten ( Polyporaceae ).
The type species is the sclerotia - Stielporling ( Polyporus tuberaster ).
Features
The species of the genus Polyporus (from the Greek "with many pores" ) usually form one-year, rare wintering or perennial fruiting bodies, which are usually stalked and clear shape of a hat, but a few species form wide ansitz end of fruiting bodies. If a stem is present, this usually is centrally located, less often eccentric or lateral stems are formed. The trama of Porlinge is fresh meaty and upon drying tough or woody. Characteristic design and name of the porous or honeycomb-like, white to cream-colored underside. The hat surface is light to dark brown, purple-brown in older fruiting bodies also. You may be tomentose hairy or covered with scales, in older specimens it is usually smooth. The spore powder is white to cream-colored. Some species form so-called sclerotia or "mushroom stones " from.
Ecology
The species of the genus live as Saprobionten on various woods, but also on prairie grass ( Polyporus rhizopilus ), and produce a white rot in infested wood. Some species can colonize a weakness parasite in addition to living trees.
Species
The genus includes 26 species worldwide. In Europe, 18 taxa occur or are expected there.
Weitlöcheriger or Borstrandiger Stielporling Polyporus arcularius
Maroon or Brown Red Stielporling Polyporus badius
Winter Stielporling Polyporus brumalis
May or summer Stielporling Polyporus ciliatus
Calibration hare or Branched Tufts Porling Polyporus umbellatus
System
Previously, many porlingsartige fungi were asked to Polyporus. Meanwhile, we group the genus to close. After Krieglsteiner the genus can be divided into five groups ( based on the species occurring in Germany at least ) that are performed depending on the author as subgenera or own genera:
- Dichomitus with more or less flat on the substrate adjacent fruiting bodies: Polyporus campestris
- Dendropolyporus with branched fruiting bodies: Polyporus umbellatus
- Melanopus with fruiting bodies whose stalks at the base or fully dyed black or dark brown are: Polyporus badius, Polyporus leptocephalus, Polyporus melanopus
- Polyporus in the true sense with non- colored stem base and about 10 microns long spurs: tuberaster Polyporus squamosus, Polyporus
- Polyporellus with not colored stem base and below 10 microns long spurs: Polyporus arcularis; Brumalis Polyporus, Polyporus ciliatus
Especially the mehrhütige calibration Hare ( Polyporus umbellatus ) and the perennial, resupinate blackening Polypore ( Polyporus campestris ) are separated in some work of Polyporus and separated into their own genus Dendropolyporus or Dichomitis.
Importance
Some Porlinge are edible and partly estimated edible mushrooms. The also parasitically living species can damage street and park trees.
