Pleurotus citrinopileatus
Lemon-yellow oyster mushroom (Pleurotus citrinopileatus )
The Citron Seitling or short lemon oyster ( Pleurotus citrinopileatus ), also called lime oyster, is a species of fungus in the family Seitlingsverwandten. The fruit bodies have white stems and yellow hat and grow in tufts. The species is a popular edible mushroom, especially in Asia. The Citron Seitling is a Holzzersetzer which also feeds on lignin, causing a white rot. The German names were introduced only in recent times by breeders.

Features
Macroscopic characteristics
The Citron Seitling forms fruiting bodies that grow side by side in several clusters. They have a flat, depressed hat of 2-6.5 cm in diameter. Its surface is bright yellow to golden brown and has a velvety, dry consistency, but loses itself in older mushrooms; the brim is now. The meat in the hat is thin and white, except in the hat skin where it is yellowish. It remains to pressure or unstained in the gate, typical smells fruity and mild taste. The slats below the hat are white and close together. Although they differ in length and thickness, but they all run on the stem down. Easy decentralized sets the stem of the hat: it is full, cylindrical and white colored. Inside it has a fleshy or fibrous consistency, the surface is smooth. In length it measures about 2-5 cm long, 2-8 mm in diameter; often it is curved or bent.
Microscopic characteristics
The spores of Zitronenseitlings are cylindrical or elliptical in shape, smooth, hyaline, amyloid, and measure 7-10 × 2.5-3.5 microns. You ever sit at fourth in the 4-5 microns long sterigmata of the basidium. The basidia even appear under the microscope club-shaped and hyaline; they have a size of 27-35 × 4-8 microns. Cystidia are absent. The trama of Zitronenseitlings is monomitisch, the hyphae have both buckles and through septa. The trama of the lamellae consists of approximately parallel hyphae; the Epicutis is undifferentiated.
Ecology
As Saprobiont the Zitronenseitling infects dead or injured wood of deciduous trees, where it degrades the lignin component and causes white rot. Natural substrates are the wood of elms and beeches. It is found in lowland forests and along rivers and requires relatively high temperatures ( 21-29 ° C) in order to grow, so that it does not form fruiting bodies under 16-18 ° C, but at higher temperatures is very tolerant. The fruits, the relative humidity of the air for the Zitronenseitling should be above 80%.
Dissemination
The Zitronenseitling occurs in Russia, Africa, and Asia.
System
The Zitronenseitling shows in its morphology similarities to Rillstieligen oyster ( Pleurotus cornucopiae ), with whom he can also cross. The former is therefore partially viewed as a variety of Rillstieligen sideways. For the Zitronenseitling no varieties or forms are recognized.
Importance
The fungus is traditionally grown in East Asia and more recently in Taiwan, USA and Europe. Apart from its value as an edible mushroom, which is reflected in numerous dishes, he also as a supplier of drugs importance, which finds in the treatment of pulmonary emphysema application. Suitable substrates are, beech, ash, alder, poplar, willow and maple.
