Pluteus cervinus

Fawn colored roof mushroom ( pluteus cervinus )

The Reddish-brown roof mushroom ( pluteus cervinus ), also known as deer brown roof fungus, is a species in the family of the roof mushroom relatives.

Features

Macroscopic characteristics

The hat of the fawn-colored roof fungus is 4 to 15 inches wide. He is initially conical - campanulate and at this age often wrinkled. With increasing age of the fungus, the shape of the hat changed to a curved shape to spread out, which is usually hunched flat. The hat surface is smooth and shines dull to silky. The center of the hat is often darker and acts occasionally almost black. Rounded blades are narrow attached or free and are pushed together. They are initially whitish and change color later to salmon pink to reddish, their edge is finely serrated. The fragile stem of the mushroom is fibrous, sometimes tapering upwards and five to twelve centimeters long and 0.7 to 2 inches in diameter. It is equipped with dark longitudinal fibers or a network drawing. The smell of the soft and white fungus flesh reminiscent of potato cellar or radishes, the taste is mild and only then slightly bitter. The spore powder is colored gray pink.

Microscopic characteristics

The Reddish-brown roof mushroom has broadly elliptic, smooth spores, which are about 6.1 to 8.4 microns long and 4.2 to 6.4 microns wide, the basidia are formed cylindrical to bulbous, 4- sporig and have no Basalschnalle. You 'll 25-38 microns long and 11-27 microns wide. There are 13-21 microns pleurocystidia found clavate - bulbous 25-47 × 11-27 microns wide cheilocystidia and thick-walled, usually with 3 hooks box at the top of 60-85 ×. The Huthautdeckschicht consists of parallel- light brown pigmented hyphae of 5-10 microns wide, with prominent long 100-250 microns and 8-30 microns thick hyphae, septa have no buckles.

Ecology

The Reddish-brown roof fungus is a populated saprobiontischer wood inhabitants of rotten stumps, stumps, felled tree trunks, stronger branches and exposed roots in the Final and late optimum phase of Vermorschung. If buried or covered with earth branches are populated, often can not be inferred directly on a wood rotting fungus. " Drill " fruiting body then spiraling to the surface. The Reddish-brown roof fungus is in Central Europe in all forest types as well as in forests, plantations and parks if suitable substrate is available. A preference for certain types of soil does not take place, as a substrate, both deciduous as well as coniferous wood are populated, preferably wood of beech and spruce Common, also rotting pile of straw outside of closed forests can be colonized. The fruiting bodies appear individually to go forth in parties, sometimes almost like tuft on the substrate, the Hauptfruktifikation place in Central Europe from late April to late November, leading or permanent copies are also found in the winter months.

Dissemination

The Reddish-brown roof mushroom comes across the Holarctic of the meridional prior to the boreal zones. In Germany the species is widespread everywhere in the entire area, it is common almost everywhere.

System

• Pluteus brunneoradiatus, the Braunfaserige roof fungus that buckles in the trama of the lamellae and especially on Hardwood ( especially beech and oak), rarely grows on coniferous wood.
• Pluteus pouzarianus, Pouzars roof mushroom, with buckles on the hyphae of the Huthautdeckschicht that grows on coniferous wood or sawdust of coniferous wood and a little later in the year will appear.
• Pluteus primus or Leading roof mushroom with buckles at all septa of Huthautdeckschicht and strikingly long (50-200 microns x 8-30 microns ) Cheilocystiden and both 2 - and 4- sporigen basidia. This type fruktifiziert earlier (from April ) and occurs in sunny locations on softwood.

Importance

The Reddish-brown roof mushroom is edible. It may taste slightly earthy.
