Taxa described in 1977

The Hymenochaetales are an order of fungi in the class Agaricomycetes. The order in its current sense is based on molecular research and not on any unifying morphological characteristics. According to one 2008 estimate, the Hymenochaetales contain around 600 species worldwide, mostly corticioid fungi and poroid fungi, but also including several clavarioid fungi and agarics. Species of economic importance include wood decay fungi in the genera Phellinus and Inonotus sensu lato, some of which may cause losses in forestry. Therapeutic properties are claimed for Inonotus obliquus ("chaga") and Phe

Bryoria is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens. The genus has a widespread distribution, especially in boreal and cool temperate areas. These lichens typically grow as slender, hair-like strands that hang from conifer trees or form small bushes, ranging in colour from dark brown to pale grey. They play important ecological roles, particularly as winter food for caribou in northern forests, where some species can accumulate in large quantities in the forest canopy. The genus contains about 35 species found worldwide,

Westoniella is a genus of Costa Rican and Panamanian shrubs in the tribe Astereae within the family Asteraceae.

Clematepistephium is a monotypic genus of orchids containing only one known species, Clematepistephium smilacifolium, endemic to the island of New Caledonia. Its closest relative is Eriaxis, also endemic to New Caledonia.

Pakaraimaea is a genus of trees in the family Cistaceae. The genus contains a single species, Pakaraimaea dipterocarpacea, from South America. It was formerly placed in subfamily Pakaraimoideae of the family Dipterocarpaceae. The species is found in the western highlands of Guyana and in adjacent Bolivar State in Venezuela. It maintains strong ectomycorrhizal associations with a wide variety of fungal species. The trees can sometimes be seen forming large stands in the western Guyanas.

Panina is a subtribe of tribe Hominini; it comprises all descendants of the human-chimpanzee last common ancestor (LCA) that are of the branch of human lineage—that is, all those ancestors of the type genus Pan (chimpanzees and bonobos). This split/divergence occurred around 8 to 6 million years ago (mya), which compares with a range of other estimates for this event——of from 15 to 3 mya. Fossils from this subtribe are typically rare because they tend to live in environments with poor fossilization. Some of the earliest chimpanzee fossils are 500,000 years of age.

Acromycter is a genus of eels in the family Congridae.

Phaeophyscia is a genus of lichen-forming fungi in the family Physciaceae. These lichens typically appear as leaf-like (foliose) growths that spread across tree bark, rocks, or other surfaces, usually in well-lit, nutrient-rich environments. Their structure consists of short or long that range in colour from pale grey to dark brown, becoming dark green when wet, and they often have dark undersides with root-like attachments (rhizines). The genus is distinguished from its relatives by its unique chemical composition and reproductive features, lacking a substance called atranorin and producing e

Periclepsis is a genus of Palaearctic moths belonging to the subfamily Tortricinae of the family Tortricidae.

Ascodichaena is a genus of fungi in the family Ascodichaenaceae. The genus was circumscribed in 1977.

Clypeococcum is a genus of lichenicolous fungi belonging to the family Polycoccaceae.

Agoma is a monotypic moth genus of the family Noctuidae erected by Sergius G. Kiriakoff in 1977. Its only species, Agoma trimenii, or '''Trimen's false tiger''', was first described by Rudolf Felder in 1874. It is known from most countries of subtropical Africa.

Protocreopsis is a genus of fungi in the class Sordariomycetes. It consisted of nine species in 2008, and up to 11 species in 2023.

Heppsora is a genus of lichenized fungi in the family Ramalinaceae.

Ioplaca is a genus of crustose lichens in the family Teloschistaceae. The genus was circumscribed in 1977 by Czech lichenologist Josef Poelt with Ioplaca sphalera assigned as the type species.
