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
