Fungi named in 1858

Akanthomyces is a genus of fungi belonging to the family Cordycipitaceae and consisting of parasites of spiders and Lepidoptera. The genus was first described by Lebert in 1858. The genus has cosmopolitan distribution. Species: Akanthomyces aculeatus Lebert Akanthomyces araneicola Akanthomyces lepidopterorum Akanthomyces neocoleopterorum Akanthomyces noctuidarum Aini, Luangsa-ard, Mongkols. & Thanakitp. Akanthomyces pyralidarum Aini, Luangsa-ard, Mongkols. & Thanakitp. Akanthomyces tortricidarum Aini, Luangsa-ard, Mongkols. & Thanakitp.

Ramalina leptocarpha, also known as the western strap lichen, is a species of cartilage lichen found in Oregon, California, and Baja California. The range of this species extends from the coast as far inland as the Sierra Nevada mountain range. R. leptocarpha often grows in epiphytic association with Ramalina menziesii. Trebouxia decolorans is its primary algal photobiont. This species was first described in 1858 by Edward Tuckerman from a collection made in Monterey, California.

Peccania is a genus of lichen-forming fungi in the family Phylliscaceae. These lichens are small and form thin, crusty patches or tiny scale-like structures that are tightly attached to rock surfaces. They partner with blue-green bacteria instead of the green algae found in most other lichens, which helps them survive in harsh, drought-prone environments and quickly resume photosynthesis after wetting. Peccania species grow exclusively on rocks, favouring well-lit locations on both limestone and acidic substrates in arid and semi-arid regions, though they can also occupy locally dry spots in

Varicellaria is a genus of crustose lichens. It is the only genus in the family Varicellariaceae. The genus contains 12 recognized species found worldwide. These lichens typically form pale bluish-grey or whitish-grey crusts on tree bark or rocks, and they produce a lichen product called lecanoric acid. Genetic studies have helped clarify the boundaries between species in this group, showing that where they grow (bark versus rock) and certain physical features are important for telling them apart.

Pyrenopsis is a genus of lichen-forming fungi in the family Porocyphaceae. The lichens grow on constantly wet, shaded rock faces where they form gelatinous crusts that soften and show reddish tints when moistened. They reproduce through small, buried fruiting bodies that open as pore-like structures at the surface.

Placidiopsis is a genus of lichens in the family Verrucariaceae. The genus was circumscribed by Italian naturalist Francesco Beltramini de Casati in 1858, with Placidiopsis grappae assigned as the type species.

Gyalecta is a genus of lichen-forming fungi in the family Gyalectaceae that contains 50 species. Gyalecta was circumscribed by lichenologist Erik Acharius in 1808. It forms associations with Trentepohlia algae.

Odontotrema is a genus of fungi in the family Odontotremataceae.

Nodulosphaeria is a genus of fungi in the family Phaeosphaeriaceae.

Cystotheca is a genus of plant pathogenic fungi in the family Erysiphaceae (powdery mildews). Members of the genus are found on Calophyllum, Castanea, Castanopsis, Murraya and Quercus species in Asia and North America.

Cladonia cristatella, commonly known as the British soldiers lichen or the British soldiers cup lichen, is a fruticose, cup lichen belonging to the family Cladoniaceae. The species was first described scientifically by American botanist Edward Tuckerman in 1858. This lichen may be confused with other red-topped lichens including Cladonia leporina and Cladonia incrassata.

Sarcopyrenia is a genus of lichenicolous (lichen-dwelling) fungi. It has 11 species. It is the only genus in Sarcopyreniaceae, a family in the order Verrucariales. Sarcopyreniaceae is one of the few families composed entirely of lichenicolous fungi. These tiny fungi produce small, black, flask-shaped fruiting bodies (perithecia) typically less than half a millimetre across, containing extremely narrow, thread-like ascospores. While they initially grow on crustose lichens, their fruiting bodies often outlast their hosts and end up sitting on bare rock, making their exact relationship with

Pannaria fulvescens is a species of foliose lichen in the family Pannariaceae. It occurs in French Polynesia and in New Zealand. Originally described in 1848 from specimens collected in Tahiti, this lichen forms overlapping lobes with a distinctive dull tawny-orange colour and scattered bluish-violet spots on the upper surface. It produces grey reproductive propagules (soredia) along the upturned, channeled lobe margins, with narrow linear lobes that broaden towards their rounded, wavy tips. In New Zealand, the species has been recorded from Northland, where it grows on both rock and tree
