The gelatinous cap relatives ( Leotiaceae ) form a family of mushrooms within the order of the Helotiales .

features

The gelatinous cap relatives usually form clearly stalked, medium-sized to large apothecia as fruiting bodies , which are sticky and often vividly colored. The excipulum consists of three layers: an outer layer with parallel or intertwined gelatinized hyphae with distant septa , an inner layer consisting of non-gelatinized hyphal tissue and an intermediate layer, which may or may not be gelatinized. The layer between the tubes consists of simple paraphyses . The tubes are cylindrical with a thickened tip (apex) and usually with a blurred amyloid (iodine-stainable) apical ring . The ascospores are hyaline and elliptical or elongated and can be septate or unseptate. A minor crop form is unknown. There is no stroma .

ecology

Gelatin cap relatives are common worldwide, but especially in the temperate zone. They live saprotrophically on the ground, especially in damp surroundings or on decaying, dead plants.

Systematics

Corda described the family in 1842. In 2006, the genus Microglossum , which was previously related to the earth tongue , was also assigned to the Leotiaceae due to molecular biological results. The dirt cup relatives may also belong in this family. The following genera belong to the family of gelatinous caps:

• Alatospora
• Geocoryne
• Gelatinipulvinella
• Jelly cap ( Leotia )
• Pezoloma
• Potridiscus
