The coal cuplings ( Geopyxis ) are a genus of the real hose mushrooms from the family of the fire pillow relatives (Pyronemataceae).

features

Macroscopic features

The charcoal cups form cup-shaped apothecia , which grow seated or stalked on the ground. The receptacle is usually sticky and hairless.

Microscopic features

The outer (ectal) excipulum , i.e. the hyphae that surrounds the actual fruiting body, consists of a textura angularis , i.e. a parenchymal- like tissue. The medullary (located in the marrow ) excipulum consists of a textura intricata (a tissue made of filamentous, strongly interwoven hyphae). The almost cylindrical tubes are operculat , i. H. formed with a lid, do not stain with Melzer's reagent and each contain eight ascospores . These themselves are single-celled, ellipsoidal and smooth or finely ornamented. They have no drops of oil or only when they are young. The paraphyses are narrow and straight.

ecology

The coal cuplings live on the ground. Some species, such as the common coal cup, prefer burn sites.

Systematics and taxonomy

Geopyxis was described by Christiaan Hendrik Persoon as early as 1822 as a section within the genus of the muglings ( Peziza ). Pier Andrea Saccardo then raised Geopyxis to the rank of genus in 1889. The Chinese mycologist Wen-Ying Zhuang described an emendation in 2006 , because the original genus only contained species with smooth spores, but the species he discovered in China also contained spores with fine warts. The species Fungorum lists the following species:

Geopyxis acetabularioides

Geopyxis alba

Geopyxis albocinerea

Geopyxis alpina

Geopyxis bambusicola

Common coal mug ( Geopyxis carbonaria )

Geopyxis carnea

Geopyxis cavinae

Geopyxis cinerascens

Geopyxis diluta

Geopyxis expallens

Geopyxis flavidula

Geopyxis foetida

Geopyxis granulosa

Geopyxis gross granulosa

Geopyxis korfii

Geopyxis majalis

Geopyxis moelleriana

Geopyxis nebulosoides

Geopyxis patellaris

Geopyxis pellucida

Geopyxis pulchra

Geopyxis pusilla

Geopyxis radicans

Geopyxis rapuloides

Geopyxis rehmii

Geopyxis striatospora
