The oak Stromabecher ( Rutstroemia firma ), also called Derber , Tough or Hard Stromabecherling due to the firm consistency of the fruiting bodies , is a type of fungus from the family of Stromabecher relatives . The species colonizes dead, debarked oak.
features
Macroscopic features
The fruiting bodies are calyx-shaped apothecia , spread out at maturity , 0.5 to 1.5 centimeters in size, with a clear stalk. Their color is yellow-brown to red-brown. Their outer excipulum has angular to prismatic cells with a significant layer of gelatinized hyphae. Their consistency is therefore quite firm and tough.
Microscopic features
The spores are hyaline , long-elliptical to slightly banana-shaped, smooth and up to five times septate. They grow to be 14.5 to 19.5 × 4 to 5.5 micrometers in size. Often secondary pores are pinched off at both ends. The ascospores lie in two rows in the asci . The asci themselves are cylindrical-club-shaped with two rows of spores and measure 140 to 155 × 10 to 11.58 micrometers. The paraphyses are filamentous with septation beginning far below.
ecology
The oak Stromabecher grows on dead, debarked oak wood, which is blackened by the fungus, that is, stromatised . It forms apothecia from September to November and is not uncommon in Central Europe. It is listed in the Austrian mushroom database in all federal states except Carinthia and Vienna.
Systematics
The oak power cup was first described by Persoon in 1801 as the Peziza company . Leopold Fuckel then put it to Ciboria , while Karsten put it to Rutstroemia . Kent P. Dumont introduced him to Poculum in 1976 . For a long time, some authors wanted to provide all of the current sockets to Ciboria . Recently, however, they have even been listed in their own family, the rutstroemiaceae, the type of which is the hard Stromabecherling.
