The Oliveoniaceae is a monotypic family of fungi in the order Auriculariales. It has only one known genus 'Oliveonia Donk with 5 accepted species. Species within the family have gelatinous basidiocarps (fruit bodies) that produce spores on septate basidia and, as such, were formerly referred to the "heterobasidiomycetes" or "jelly fungi". All appear to be saprotrophic, growing on dead wood or plant remains.

Many of the species fruit on living herbaceous seed plants or ferns, but also on dead wood and litter.

a genus of resupinate jelly fungi

genus is characterized by strictly reupinate basidiomata, monomitic hyphal system with clamped or unclamped hyphae, clavicate cystidia in three species, clavate or somewhat conical basidia, which may be pleural, at least in young stages, and repetitive spores.

Species
As accepted by GBIF;
 * Oliveonia citrispora (Hauerslev) P.Roberts (Basionym: Sebacinella citrispora Hauerslev)
 * Oliveonia fibrillosa (Burt) Donk (Basionym: Sebacina fibrillosa Burt)
 * Oliveonia nodosa (Hauerslev) P.Roberts (Basionym: Sebacinella nodosa'' Hauerslev)
 * Oliveonia pauxilla (H.S.Jacks.) Donk (Basionym: Corticium pauxillum'' H.S.Jacks.)
 * Oliveonia termitophila (Oberw. & Ryvarden) P.Roberts (Basionym: Monosporonella termitophila Oberw. & Ryvarden)

Habitat and distribution
Species are mainly saprotrophic, occurring in the soil and producing fruit bodies on dead stems and plant detritus. Some occur on attached leaves and stems. Several species have been isolated from orchid mycorrhiza. Distribution appears to be cosmopolitan.

Oliveonia ﬁbrillosa is a cosmopolitan species known from Asia, Europe, North and South America.

Oliveonia fibrillosa]] and Oliveonia pauxilla have been found in Finland.

Taxonomy
The genus name of Oliveonia is in honour of Lindsay Shephard Olive, (1917-1988), who was an American botanist (Mycology), who worked at various different Universities including; Louisiana State University, Columbia University and the University of North Carolina. She also wrote 'A New Orchid from the Southern Appalachians', 1975.

The genus was circumscribed by Marinus Anton Donk in Fungus vol.28 on page 20 in adnot. 1958.

History
Family OLIVEONIACEAE P. Roberts Folia Cryptog. Estonica 33: 128. 1998. Oliveoniaceae was recently proposed by Roberts (1998) to accommodate the single genus Oliveonia Donk. It is small genus with only ﬁve species which were re-described and illustrated by Roberts (1999), who also provided a key to their identiﬁcation.

The family was established in 1900 by German mycologist Gustav Lindau to accommodate a single, neotropical species, Hyaloria pilacre. Lindau considered his new family to be close to the Tremellaceae, but distinguished by the "angiocarpous" or gasteroid development of its fruit bodies (meaning that the spore-bearing hymenia were covered until maturity, rather than exposed). The Hyaloriaceae were placed within the order Tremellales by most subsequent authors,  until 1984, when American mycologist Robert Joseph Bandoni revised this group of fungi and placed the family within the Auriculariales. Wells (1994) later extended the Hyaloriaceae to include other genera with "myxarioid" basidia (septate basidia with an enucleate stalk), previously placed in the Aporpiaceae or Myxariaceae.

Current status
Initial molecular research, based on cladistic analysis of DNA sequences, has supported the placement of the Hyaloriaceae within the Auriculariales and has also supported Wells' placement of the genus Myxarium within the family, though not all genera with "myxarioid" basidia are included.

Description
Species within the Hyaloriaceae form gelatinous fruit bodies that are pustular, lobed, or effused (Myxarium species) or resemble miniature puffballs (Hyaloria species). Microscopically, all possess "myxarioid" basidia.

Distribution and habitat
Species appear to be saprotrophic, growing on dead wood or plant remains. Their distribution is cosmopolitan.
