Fungi named in 1789

Boletus aereus, commonly known as the queen bolete, dark cep, or bronze bolete, is a species of fungus in the family Boletaceae. Described in 1789 by French mycologist Pierre Bulliard, it is closely related to several other European boletes, including B. reticulatus, B. pinophilus, and the popular B. edulis. Some populations in North Africa have in the past been classified as a separate species, B. mamorensis, which has been shown to be phylogenically conspecific to B. aereus and is now regarded as a synonym. The fungus produces spore-bearing fruit bodies above ground in summer and autumn.

Xylaria is a genus of ascomycetous fungi commonly found growing on dead wood. The name comes from the Greek xýlon meaning wood (see xylem). 'Outline of Fungi and fungus-like taxa' by Wijayawardene et al. lists up to c. 571 species (in 2020), and around 454 records are listed by Species Fungorum (including synonyms). Two of the common species of the genus are Xylaria hypoxylon and Xylaria polymorpha. Xylaria hypoxylon, known by the common names stag's horn and candle-snuff fungus, is the most conspicuous because of its erect, 3–7 cm tall, antler-like ascocarps (fruitbodies) which are black at

Endocarpon is a genus of saxicolous (rock-dwelling), squamulose lichens in the family Verrucariaceae. It comprises 23 species. The genus is characterised by its enclosed fruiting bodies (perithecia) embedded within the scales and its compartmentalised spores. Species in this genus typically grow on rocks, often in areas that experience periodic moisture.

Octospora is a genus of fungi in the family Pyronemataceae.

Peltigera venosa, commonly known as the fan lichen, is a species of foliose lichen in the family Peltigeraceae. It was first described by Carl Linnaeus in his 1753 work Species Plantarum as Lichen venosus. German botanist Georg Franz Hoffmann transferred it to the genus Peltigera in 1789. P. venosa can be found in temperate and boreal regions of North America, Europe, and Asia, while occasionally being found in drier climates such as mountainous Arizona. The thallus color depends on its level of hydration: when wet, it is deep green, while when dry it is dark grey-green. The lobes that
