The lemon yellow oyster mushroom or lemon oyster mushroom for short ( Pleurotus citrinopileatus ), also called lime oyster mushroom , is a type of mushroom from the relatives of the oyster mushrooms . The fruiting bodies have white stalks and yellow caps and grow in tufts. The species is a popular edible mushroom , especially in Asia . The lemon yellow mushroom is a wood decomposer that also feeds on lignin and thus causes white rot . The German names have only recently been introduced by breeders.

Macroscopic features
The lemon yellow mushroom forms fruiting bodies that grow in clusters next to each other. They have a flat, depressed hat 2–6.5 cm in diameter. Its surface is light yellow to golden brown and has a velvety, dry consistency, which is lost with older mushrooms; the brim sticks out. The flesh in the hat is thin and white, except in the area of the hat skin where it becomes yellowish. It remains uncolored when printed or when it is cut, has a typical fruity smell and tastes mild. The lamellas under the hat are white and close together. Although they differ in length and thickness, they all run down the handle . The handle is slightly decentralized on the hat: it is full, cylindrical and colored white. Inside it has a fleshy or fibrous consistency, the surface is velvety. It measures about 2–5 cm in length and 2–8 mm in diameter; it is often curved or bent.
Microscopic features
The spores of the lemon oyster mushroom are cylindrical or elliptical in shape, smooth, hyaline , amyloid , and measure 7-10 × 2.5-3.5 µm . Four of you sit on the 4–5 µm long sterigmata of the basidium. The basidia themselves appear club-shaped and hyaline under the microscope; they have a size of 27–35 × 4–8 µm. There are no cystids . The trama of the lemon oyster mushroom is monomitic, the hyphae have both buckles and septa . The trama of the lamellae consists of approximately parallel hyphae; the epicutis is undifferentiated.
ecology
As a saprobiont , the lemon oyster mushroom attacks dead or damaged wood of deciduous trees, where it breaks down the lignin component and thus causes white rot . Natural substrates are elm and beech wood . It can be found in alluvial forests and along rivers and needs comparatively high temperatures (21-29 ° C) to grow, so that below 16-18 ° C it does not develop any fruiting bodies, but is very tolerant in the upper temperature range. When fruiting, the relative humidity of the air for the lemon oyster mushroom should be over 80%.
distribution
The lemon oyster occurs in Russia, Africa and Asia.
Systematics
The lemon oyster mushroom shows similarities in its morphology to the rill-stemmed oyster mushroom ( Pleurotus cornucopiae ), with which it can also be crossed. The former is therefore sometimes viewed as a variety of the Rillstieligen Seitling. No varieties or shapes are recognized for the lemon oyster mushroom.
meaning
The mushroom is traditionally grown in East Asia and more recently in Taiwan, USA and Europe. In addition to its value as an edible mushroom, which is reflected in numerous dishes, it is also important as a supplier of medicinal substances that are used in the treatment of emphysema . Suitable substrates are red beech , ash , alder , poplar , willow and maple .
