Mouse-tail rot ( Baeospora myosura )
|( Fr .: Fr. ) Singer & AH Sm.|
The mouse tail rot or late cone rot ( Baeospora myosura ) is a species of fungus from the family of vertigo relatives . Like the “real” cones ( Strobilurus sp.), The species specializes in decomposing cones .
The thin-fleshed fruit bodies initially have an almost hemispherical, later expanded and circular hat, which reaches a diameter of 0.5-2 cm. The smooth surface shows a flesh-brown color in wet weather and an ocher-brownish color in dry conditions; the edge is tinted lighter. There are whitish, ephemeral flakes on the hat skin. The initially whitish lamellae later have a pale straw-yellow color. They are narrow, stand very close together and do not reach the stem. The cutting edges are smooth and colored like the rest of the lamellar surface. The spore powder is white. The cylindrical stem becomes 1–4 (–8) cm long and 1–2 mm wide. It is gray-reddish, dark brown towards the base and has a cartilaginous consistency. The stem is full when young, but hollow when it is old. The outside is covered with fine villi. The lower end of the stem ends in a bald, root-like extension. The light beige meat smells inconspicuous and tastes mild.
The 3–4.5 × 1.5–2.5 µm large spores are colorless, elliptical, smooth and amyloid . The fibrous cap skin consists of hyphae with buckles on the septa . At the lamellar edges there are cheilocystids that do not have crystals.
The cone root ( Strobilurus sp.), Which occur on the same substrate, can be similar . These usually appear in spring, but overlaps can also occur. They have a smooth stem, less dense lamellae and larger, inamyloid spores.
Ecology and phenology
The mouse-tail ruff is found in coniferous forests, especially in spruce, but also in fir-spruce and beech-spruce-fir stands. Due to the increased settlement of spruce trees by humans and the low demands of the fungus, it could spread very easily. The agaric fungus lives saprotrophically on cones of conifers that were shed in the previous year or earlier. The fungus colonizes them in the late initial to optimal phase of the rot. Spruce cones , sometimes from Scots pine, serve as substrate for over 90 percent . In rare cases, the fungus also grows on cones of firs and larches . Douglas fir cones are also given as a substrate for North America . Presumably it can also appear on it in Europe.
The fruiting bodies appear singly or in groups, usually in late autumn. In some regions it can occur as early as September. Depending on the weather, isolated finds are also possible from August to March or in summer.
The mouse-tailed ruff is common in the Holarctic . It can be found in North America, Europe and North Asia (Caucasus). In Europe, the fungus can be found from Great Britain, the Benelux countries and France in the west to Estonia and Belarus in the east and from Spain, Italy and Romania in the south to Fenno Scandinavia in the north. In Germany it can be found scattered in the lowlands up to the low mountain range threshold. The species is regionally frequent further south.
The mouse-tailed turnip is edible, but the tough handle is unsuitable for consumption. The mushroom is not productive.
