Neolentinus ponderosus, commonly known as the giant sawgill, or ponderous lentinus, is a species of fungus in the family Gloeophyllaceae. Found in western North America, it was originally described in 1965 as a species of Lentinus by American mycologist Orson K. Miller.
Arthopyrenia is a genus of fungi in the family Trypetheliaceae. It was formerly classified in the eponymic family Arthopyreniaceae, but molecular phylogenetics studies showed that the type species, Arthopyrenia cerasi, was a member of the Trypetheliaceae.
Psilocybe makarorae is a species of psilocybin mushroom in the family Hymenogastraceae. Officially described as new to science in 1995, it is known only from New Zealand, where it grows on rotting wood and twigs of southern beeches. The fruit body (mushroom) has a brownish cap with lighter coloured margins, measuring up to 3.5 cm (1.4 in) wide. The cap shape is either conical, bell-shaped, or flat depending on the age of the mushroom, and it features a prominent umbo. Although the whitish stem does not form a true ring, it retains remnants of the partial veil that covers and protects the gills of young fruit bodies. P. makarorae mushrooms can be distinguished from the similar North American species Psilocybe caerulipes by microscopic characteristics such as the presence of cystidia on the gill faces (pleurocystidia), and cheilocystidia with more elongated necks. Based on the bluing reaction to injury, P. makarorae is presumed to contain the psychedelic compounds psilocybin and psilocin.
Hygrophorus marzuolus, commonly known as the March mushroom, is a species of fungus in the family Hygrophoraceae. It is known from Asia, Europe, and North America, where it grows on the ground in mixed forests at high elevations.
Hygrophorus purpurascens, commonly known as the purple-red waxy cap, is a species of agaric fungus in the family Hygrophoraceae. Its cap has a pink background color with streaks of purplish red overlaid, and mature gills have red spots.
Bacidina sorediata is a species of foliicolous (leaf-dwelling) lichen in the family Ramalinaceae. Found in the Seychelles, it was described as new to science in 2011. It is characterized by its distinct sorediate thallus and pale yellow to orange apothecia.
Acrocordia gemmata is a species of lichen belonging to the family Monoblastiaceae.
Parmelia ambra is a fossilised species of foliose lichen in the family Parmeliaceae. Found in Dominican amber and described as a new species in 2000, the fossil has been used in subsequent studies of lichen evolution.
Biatora radicicola is a species of corticolous (bark-dwelling) and saxicolous (rock-dwelling), crustose lichen in the family Ramalinaceae. It is found in various locations in Europe, where it grows in sheltered and humid microhabitats, often on exposed root bark at the base of trees.
Trichothelium caudatum is a species of corticolous (bark-dwelling), crustose lichen in the family Trichotheliaceae. Found in Bolivia, Ecuador, and Peru, it was formally described as a new species in 2004 by lichenologist Robert Lücking. The species epithet refers to its characteristic caudate ascospores, i.e., tapering and elongated, with a tail-like extension at one end.
Hypogymnia tenuispora is a rare species of foliose lichen in the family Parmeliaceae. Found in China's Yunnan province, it is characterised by its uniquely narrow ascospores and crowded lobes, which help distinguish it from other similar Hypogymnia species.
Schaereria porpidioides is a species of saxicolous (rock-dwelling), crustose lichen in the family Schaereriaceae. It is found in the Falkland Islands.
Placomaronea fuegiana is a species of saxicolous (rock-dwelling), crustose lichen in the family Candelariaceae. Found in South America, it was formally described as a new species in 2009 by Martin Westberg and Patrik Frödén. The type specimen was collected by the second author in Tierra del Fuego, Argentina, where it was found growing on sandstone. The species epithet fuegiana refers to the type locality. It also occurs in Pali-Aike National Park, where it grows in the pits of volcanic rocks.
Malmidea cineracea is a little-known species of corticolous (bark-dwelling), crustose lichen in the family Malmideaceae. It is found in Nicaragua.
Caloplaca patagoniensis is a species of lignicolous (wood-dwelling), crustose lichen in the family Teloschistaceae. It is found in Chile. It forms small thallus patches, with distinctive areoles that change from whitish or greyish-yellow to deep orange or brownish-orange, often covered by a bright orange blastidious mass. Its fruiting bodies (apothecia) are dark reddish-orange and initially immersed in the substrate, while its spores are ellipsoid to elongated, and the species contains parietin, turning purple when exposed to a potassium hydroxide solution.
Fellhanera ivoriensis is a species of foliicolous (leaf-dwelling) lichen. First described in 2001, this species is distinguished from its relatives in the Fellhanera by its soredia-covered thallus and the characteristics of its apothecia. It is native to the Ivory Coast in West Africa.
Micarea viridileprosa is a species of crustose lichen in the family Pilocarpaceae that was first described in 2001. This crustose lichen is known to grow on bark, wood, and soil, and is distinguishable by its bright greenish soredia.
Flavoplaca oasis is a species of saxicolous (rock-dwelling), crustose lichen in the family Teloschistaceae. It is widely distributed across Europe, and has been reported in Western Asia, China, and North Africa.
Caloplaca rinodinae-albae is a lichenicolous (lichen-dwelling) species of crustose lichen in the family Teloschistaceae, first described in 1987. This species is unique for its parasitic growth on the lichen Helmutiopsis alba. Characteristics of the lichen include its small, rounded, pale orange thalli and its ability to form larger patches through the confluence of individual thalli.
Corticorygma is a monotypic fungal genus in the subfamily Graphidoideae of the family Graphidaceae. It contains a single species, the corticolous (bark-dwelling) crustose lichen Corticorygma stellatum. This script lichen is found in the shaded understory of rainforests in the Brazilian states of Rondônia and Paraná.
