Albatrellus

Albatrellus - ovinus is the model type of the genus

The Schafporlinge ( Albatrellus ) are the type genus of the family of Schafporlingsverwandten ( Albatrellaceae ). The genus contains ground-dwelling Ectomykorrhizapilze that are associated with deciduous and coniferous trees. The fleshy, usually only short-lived fruiting bodies are divided into a hat and a central or eccentric stem. The hymenophore is Roehrig. The typical order gloeoplere hyphae are common, however, Zystiden missing. The spores are smooth, more or less elliptical and hyaline. You can be amyloid or inamyloid. After molecular biological studies have shown that the genus is polyphyletic, numerous species have been placed in new genera. The type species of the genus is Albatrellus ovinus (Fr.) KOTL. & POUZ.

Description

The annual and usually short-lived fruiting bodies are divided into pileus and stipe. The stalk may be centrally or eccentrically, a universal veil ( a membrane that completely surrounds the stem and the hat ) is missing. The cap is 3-18 cm wide, arched, spread out flat or recessed funnel-shaped. He is smooth to tomentose, dry and whitish, yellowish, ocher- yellow to brown in color. The hymenophore is Roehrig. The pores are small and white, colored yellow or yellow ocher. The stem is 1-8 cm long and 1-4 cm wide. A velum partiale ( a membrane which the spore-bearing lamellae or tubes enclosing the hat brim to the stem ) or a ring ( partiale a remnant of the velum remains the preserve on a stick ) is missing. The meat is soft and fragile until fairly tough. The spore powder is white to cream-colored.

The 3.5 to 11 microns long and 2.5-6.5 microns wide spores are more or less circular to elliptical, smooth, thick-walled and without Keimpore. They are usually inamyloid, so do not react with Jodreagenzien. The basidia have partially buckles, cystidia absent at their base. The Hyphensystem is monomitisch, there is only one Hyphentyp. At septa buckles can be configured or missing, the hyphae are often inflated. The hat skin ( Pileipellis ) is a Trichoderma, a tomentum or Palisadoderm.

Ecology

The Scharfporlinge are Ectomycorrhizpilze of deciduous and coniferous trees. Maybe, but they can also feed as a saprophyte.

System

The genus was first described in 1821 by Samuel Frederick Gray scientifically .. There are numerous heteronymous Synonyms: Caloporus Quél. non P.Karsten (1886 ), Polyporus sect. Ovinus Lloyd (1911) and ovinus ( Lloyd) Torrend (1920), Scutiger (sensu Murrill) Paulet (1903) and Albatrellopsis Teixeira ( 1993).

After molecular biological studies have shown that the genus is polyphyletic Albatrellus, numerous species were separated and placed in newly defined genera. These species include the brown Haarstielporling ( Jahnoporus hirtus ), The Goat - Porling ( Scutiger pes - caprae ), the meadow Porling ( Xanthoporus syringae ) and Polyporoletus sublividus a North American species in separate genera. In addition, were able to show Steven L. Miller and his coauthors that Albatrellus for Russula clade belongs and is therefore einzuordenen in order Russulales.

Species

Worldwide, there are at least 14 known species, of which are in Germany, Austria and Switzerland four species. The Haarstielporlinge ( Jahnoporus ) and the Ziegenfuß - Porlinge ( Scutiger ) not now belong to this genus. The Ziegenfuß - Porlinge distinguished by their much larger spores and the Haarstielporlinge have large, spindle-shaped spores. The saprophytic and potentially parasitic species such as the meadow Porling ( Xanthoporus syringae ) were separated.
