The yellow-green comb Porling ( Laeticutis cristata , Syn. : Albatrellus cristatus , Scutiger cristatus ) is a mushroom art from the family of Porlingsverwandten (Albatrellaceae). It grows from September to November in the deciduous forest under beeches and oaks and can be recognized by its characteristic brown-green hat.

Macroscopic features

The hat of the mushroom is about 5–20 cm wide (connected fruiting bodies often larger) and of a round or misshapen shape. It is slightly curved to flat or wavy. The surface is velvety to leathery and often becomes cracked with age. The color of the hat varies between yellow-brown and olive-green, often with a red-brown tint in the middle with old mushrooms; on the wavy edge of the hat, however, olive green is usually predominant. The hat retains its color even when it dries in the herbarium . Often several hats and stems are fused together. The tubes of the Kammporlings have a length of 1–5 mm and run down the handle; the whitish-yellow or greenish pores are angular and about 0.3–1 mm in size. The yellowish stem measures approx. 3–6 cm in length and 1–2.5 cm in width. It sits in the middle of the hat or slightly off-center, with a velvety surface. The tough, white flesh turns a dirty yellow-green when cut; it smells faintly mushroom-like, on the tongue it is bitter or tasteless. It reacts with potassium hydroxide by a reddish color.

Microscopic features

The spores measure 5-7 x 4-5 micrometers and are approximately round, translucent, and slightly amyloid ; they form a white spore powder. The hyphae are (almost) without buckles .

Species delimitation

It can be confused with the Yellow Goat's Foot ( Albatrellus ellisii ) in North America and the Goat's Foot Porling ( Scutiger pes-caprae ) in Europe. However, the former usually grows under pine trees, has a scaly hat and turns green when damaged. Its distribution area is also more west of the Rocky Mountains, while the spores are somewhat larger and more elliptical in shape. The goat's foot porling is brown and also more scaly, with a coarse, yellow, detached stem, and its spores are larger and elliptical. Another distinguishing feature is the large pores that are more than a millimeter in size. In North America, its occurrence is also limited to the southeast and southwest of the United States.

Ecology and diffusion

The yellow-green Kamm-Porling forms mycorrhiza with deciduous trees , especially beeches and oaks , rarely only with conifers . It usually grows directly on the forest floor, where it can be found from September to November. The European distribution area roughly corresponds to that of the beech, although the fungus is virtually non-existent in the lowlands. In North America it is widespread east of the Rocky Mountains .

Systematics

No subspecies are recognized for the yellow-green comb porling. Earlier it was placed in the genus of the Porlinge ( Polyporus ), then it was in the genus Albatrellus for a long time until it was placed in the genus Laeticutis (= " beautiful skin ") in 2010 .

meaning

The yellow-green Kamm-Porling is inedible due to its tough meat and its bitter taste.
