Taxonomy and Systematics
Species: Bisporella citrina (Batsch: Fries) Korf and Carpenter
Notes on taxonomy: Bisporella citrina was first identified by August Batsch in 1789. Its name derives from the word "citrin," which means "lemon-yellow." Synonyms for this species include: Helotium citrinum and Calycella citrina. It is commonly known as Yellow Fairy Cup and Lemon Disco.
Bisporella citrina are made of bright yellow, discoid fruiting bodies. As they mature or grow dry their color changes to a orangish-yellow. The inside surface and outside surface of these bodies are smooth and identical in coloration, which makes it easy to distinguish them from Lachnellula agassizii-another bright yellow sac fungi. These saucer-shaped bodies grow to be 3 millimeters in length; the specimen that I measured was 2 millimeters across. As also described in the literature, my specimen had stalk-like base; though, the literature also notes that sometimes these "stalks" are completely absent.
Bisporella citrina fruits on logs and branches of hardwoods between summer and fall months in Europe and North America.
Campus distribution and habitat
I identified this species twice--once on campus and once at Woodford State Park. My first specimen was collected at Woodford State Park (15 miles due east of campus) on September 26, 2011. My second specimen was found on October 3, 2011 at 1:25 pm off of the Blue trail. Both specimen were found in large clusters and on the bark of decaying logs surrounded in moss.
