Description
 
 

Yellow Fairy Cup Fungus is common and widespread. It is found in North America, Central and South America, Europe, Asia, and Australia. In North America it is especially common in the eastern United States and the on west coast. It is saprobic, obtaining nutrients from rotting wood. It grows in dense clusters on dead and decaying logs and stumps of hardwoods and sometimes conifers. In Minnesota it can be seen from summer through fall.

The fruiting body is a small, saucer-shaped cup with or without a tiny stalk. The cups are 1 32 to (1 to 3 mm) in diameter and 1 32 to 1 16(1 to 2 mm) tall. The species epithet citrina means “lemon yellow” but the upper surface of the cups may be bright lemon yellow or bright orangish-yellow. The underside is the same color but may be paler. They are globular when they first appear, expanding to saucer-shaped or disc-shaped as they mature. The stalk, if present, is rarely more than 1 32 (1 mm) long.

The spore print is white.

This species was classified as Peziza citrina when it was first described in 1789. In 1885 it was transferred to the genus Calycella. For many decades it went under the names Calycella citrina or Helotium citrinum, depending on the preference of the author. In 1974 it was noted that Calycella was a synonym for Calycina, so Helotium citrinum was transferred to the genus Bisporella. Some time before 2008, all Calycella species were transferred to the genus Bisporella. In 2019, morphological and molecular analysis showed Bisporella citrina to be separate from the species of Bisporella, and it was transferred to the genus Calycina.

Další názvy
= voskovička citrónová

Rozšíření a ekologie: 
Roste dosti hojně v září až prosinci ve velkých skupinách na stinných místech na mrtvém dřevě listnáčů, které jsou již bez kůry. Upřednostňuje buky a habry. Někdy ji najdeme i za mírné zimy.

Popis:
Plodnice mají průměr 1--3 mm, jsou miskovité, později až terčovité, s vyklenutým rouškem. Povrch je hladký a lysý. Mají citrónově žlutou, někdy až žloutkově žlutou barvu, se zvýrazněným okrajem. Třeň je kratičký, zužuje se směrem dolů, nebo úplně chybí. Spory jsou elipsoidní, hladké, 9--14 × 3--5 µm velké, s olejovými kapkami na každém konci.

Záměny: 
Voskovičce citrónové se podobají některé jiné drobné houby žluté až oranžové barvy -- kropilka rosolovitá (Dacrymyces stillatus) a kropilka menší (Dacrymyces minor) rostoucí také na mrtvém dřevu mají plodničky spíše polštářovité. Oranžovka vřetenovýtrusná (Byssonectria fusispora) má obvykle sytější oranžovou barvu a roste na zemi. Hovník obecný (Ascobolus stercorarius) roste na exkrementech, stejně jako žlutěnky -- ž. zrnitá (Cheylimenia granulata) a ž. mrvelníkovitá (Cheylimenia theleboloides), ty mají na okraji plodniček brvy.

Poznámka:
Je to nejedlá houba.
