Exidia Nigricans
''Exidia nigricans'' (common name Witches' butter) is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species throughout the northern hemisphere, typically growing on dead attached branches of broadleaf trees. It has been much confused with ''Exidia glandulosa''. Taxonomy The species was originally described from England as ''Tremella nigricans'' by William Withering, Withering in 1776, based on a phrase name published by Dillenius in 1741. It was subsequently considered a synonym of ''Exidia glandulosa'', until Marinus Anton Donk, Donk revised species concepts in 1966 and placed it in synonymy with ''Exidia plana''. Changes in the starting point for fungal nomenclature has made ''Exidia plana'' illegitimate, however, leaving ''Exidia nigricans'' as the earliest name for the species.Roberts, P. (2009). ''Exidia nigricans'': a new and legitimate name for ''Exidia plana''. ''Mycotaxon'' 109: 219–220. Molecular research has shown that ''Exidia glandulo ...

Exidia Glandulosa
''Exidia glandulosa'' (common names black witches' butter, black jelly roll, or warty jelly fungus) is a jelly fungus in the family Auriculariaceae. It is a common, wood-rotting species in Europe, typically growing on dead attached branches of oak. The fruit bodies are up to wide, shiny, black and blister-like, and grow singly or in clusters. Its occurrence elsewhere is uncertain because of confusion with the related species, ''Exidia nigricans''. Taxonomy The species was originally described from France as ''Tremella glandulosa'' by Bulliard in 1789. It was subsequently placed in ''Exidia'' by Fries in 1822. Fries, however, modified Bulliard's species concept to include a second, effused, coalescing species—the name ''Exidia glandulosa'' serving for both. This combined concept was used until Neuhoff separated the two species in 1936. Unfortunately, Neuhoff gave the name ''Exidia glandulosa'' to the effused species, adopting the name ''Exidia truncata'' for Bulliard's origina ...

Tremella Mesenterica
''Tremella mesenterica'' ( common names include yellow brain, golden jelly fungus, yellow trembler, and witches' butter) is a common jelly fungus in the family Tremellaceae of the Agaricomycotina. It is most frequently found on dead but attached and on recently fallen branches, especially of angiosperms, as a parasite of wood decay fungi in the genus ''Peniophora''. The gelatinous, orange-yellow fruit body of the fungus, which can grow up to diameter, has a convoluted or lobed surface that is greasy or slimy when damp. It grows in crevices in bark, appearing during rainy weather. Within a few days after rain it dries into a thin film or shriveled mass capable of reviving after subsequent rain. This fungus occurs widely in deciduous and mixed forests and is widely distributed in temperate and tropical regions that include Africa, Asia, Australia, Europe, North and South America. Although considered bland and flavorless, the fungus is edible. ''Tremella mesenterica'' produces ca ...

Dacrymyces
''Dacrymyces'' is a genus of fungi in the family Dacrymycetaceae. Species are saprotrophs and occur on dead wood. Their distribution is worldwide. Basidiocarps (fruit bodies) are ceraceous to gelatinous, often yellow to orange, and typically disc-shaped to cushion-shaped. The genus has traditionally been differentiated from other genera in the Dacrymycetaceae on the basis of basidiocarp morphology, following (in recent years) the monograph of New Zealand mycologist Robert McNabb. Molecular research, based on cladistic analysis of DNA sequences, has however shown that morphology is not a good indicator of natural relationships within the Dacrymycetaceae. As a result several species formerly referred to ''Dacrymyces'' have been moved to ''Dacryonaema'' or '' Dendrodacrys''. Species *'' Dacrymyces adpressus'' *'' Dacrymyces albidus'' *'' Dacrymyces ancyleus'' *'' Dacrymyces ancoratus'' *''Dacrymyces aquaticus'' *'' Dacrymyces aureosporus'' *'' Dacrymyces australis'' *'' Dacrymyces ...
