Macroscopic features
The hat usually reaches a diameter of two to five centimeters. It is initially bell-shaped to conical in shape, and when it is older it is flat when it is expanded. It is chestnut brown in color, black-brown in the middle. Towards the edge of the hat, the tint fades to light brown to whitish. However, the hat is hygrophan , so that it appears leather-brown to yellowish in dry weather. The brim of the hat is grooved through in wet weather. The surface appears velvety due to the numerous long cystids .
The lamellae are initially whitish in color, but with age they acquire a reddish-yellow to ocher-reddish tint. They are almost crowded, relatively thick and bulbous. They are rounded or attached with hooks; in old age they are almost free.
The stem is between four and seven centimeters long and four to seven millimeters thick. It is stiff, tough and dark to black-brown in color. His surface appears through the Kaulo Zystiden velvety. The tip of the handle is frosted. The stem is easy to detach from the hat.
The flesh ( trama ) has a brownish tint. Fresh fruit bodies smell of cucumber, old specimens of fish oil.
The spore powder is rust-ocher to orange-brown in color. In var. Leucospora it has an almost white tone.
Microscopic features
The trama of the slats has a regular structure. The cap skin consists of lying hyphae ; their septa have buckles . The Gloeo cystids are very large, lanceolate and hyaline . The caulocystids are arranged in clusters. The basidia are four-pore and have a buckle at the base. The spores are ellipsoidal-spindle-shaped and have a smooth surface. They are light reddish in color, inamyloid and mononuclear.
Species delimitation
The cucumber slice is relatively little variable in its color. It is characterized by the strong smell of cucumber and the velvety surface of the hat and stem.
ecology
The cucumber carving can be found in forests, roads and streams, gardens and ditches, among other places. It grows on the ground on plant waste and pieces of wood, also between grass. The fruiting bodies appear from late July to November. In particularly sheltered places and under favorable weather conditions, they occur sporadically in spring and over winter.
distribution
The cucumber slice is distributed meridional to boreal in the Holarctic . It can be found in western North America, Europe, North Africa and North Asia. In Europe, the area extends from Spain, Corsica and Romania to the north to the Hebrides , Fennoscandinavia and Iceland and east to Estonia and Belarus. In Germany, the fungus can be found in all federal states from the Danish border to the Alpine region.
Systematics
The var. Latifolia with reddish spore powder and very wide lamellae and the var. Leucospora with almost white spore powder and narrow lamellae are of greater taxonomic importance . Both have a small hat (max. 1.5 cm) and a striped brim.
