The black and white disc laurel ( Gyromitra melaleuca , syn .: Discina melaleuca ) is a type of mushroom from the family of poison lorel relatives . The fungus, which grows scattered or rarely in the hills and mountains, forms flat fruiting bodies .
features
Macroscopic features
The flat fruit bodies have downwardly bent or slightly curled edges. They are corrugated like a brain and wrinkled with the center pressed down and firmly pressed against the ground. The irregularly bent fruiting bodies reach widths of 2–8 cm. Its fruit layer is colored from chestnut brown to brown-black, although purple-like shades are also possible. The outside appears whitish and contracts at the bottom in a short stalk . This is only 0.3-0.4 cm long. The waxy flesh is yellowish to slightly ocher in color, somewhat brittle and has no characteristic smell or taste.
Microscopic features
The fruit layer ( hymenium ) is on the surface of the fruit body. The spores are irregularly elliptical, have no appendages, and measure 15–20 × (7.5) 9–10 (11) µm. They are transparent ( hyaline ) and contain two to three drops of oil inside. Its surface is ornamented with a fine warty finish . There are eight spores in each of the 310–350 × 12.5–15 µm tubes ( asci ). The paraphyses are 5 µm thick at the slightly clubbed tip 7–9 µm thick and have a slightly brownish content.
Species delimitation
Larger fruiting bodies of the black and white disc Lorchel can be confused with the veiny Morel cup, which smells like chlorine . A very similar species is the violet-black thick cup ( Pachyella violaceonigra ), the asci of which turn blue with iodine .
Ecology and phenology
As a saprobiont, the black and white disc Lorchel is rarely found in deciduous and coniferous forests, preferably in the mountainous regions. The fruiting bodies grow individually or gregariously on bare, loamy soil as well as between leaves and coniferous litter. They are formed in spring.
meaning
The species is in need of care due to its rarity; No information on edibility is available.
