Neobulgaria pura Taxonomy and Etymology
The basionym of this species was originally defined by Persoon and accepted by the great Swedish mycologist Elias Magnus Fries in his 1822 publication Systema Mycologicum. The currently accepted scientific name of this species was established in 1921 by Austrian mycologist Franz Petrak (1886 - 1973).
Neobulgaria pura is the type species of its genus, which was circumscribed by Petrak in 1921.
Despite the word 'Jelly' appearing in its common name and very well reflecting its texture, this is not one of the hererobasidiomycetes 'Jelly Fungi' which belong to the - Class Basidiomycota. Neobulgaria pura belongs to the Ascomycota, as also does its swarthy lookalike Bulgaria inquinans.
In 1969 Neobulgaria pura var. foliacea (Bres.) Dennis & Gamundí was separated from the nominate form Neobulgaria pura var. pura; it is similar but has ripple-folded (brain-like) fruitbodies rather than individual 'buttons'. Older synonyms of this variety include Coryne foliacea Bres., and Neobulgaria foliacea (Bres.) Dennis.
Neobulgaria, the genus name, maybe a reference to the leathery skin - a bulgar was a leather pounch within which wine was carried. Any other suggestions would be most welcome! Much more straightforward, the specific epithet pura comes from the Latin adjective purum and means pure or clean.
