Elixia cretica is a rare species of corticolous (bark-dwelling), crustose lichen in the family Elixiaceae. It is only known to occur in a single location in the mountains of the Greek island of Crete.
The lichen was described as a new species in 2010 by lichenologists Toby Spribille and H. Thorsten Lumbsch. The type specimen was collected from Lefka Ori, a mountain range in Western Crete. The type locality is 3 km (1.9 mi) southwest of the village Omalos, between the mountains Mávri Kimite and Tourli, at an elevation of 1,125 m (3,691 ft). There, the first author found the lichen growing on the bark of Turkish pine (Pinus brutia), near the base of tree. It is only known from the type locality. [1]
According to the authors, the lichen first "defied any attempt at identification" before an association with Elixia was made. Subsequent molecular phylogenetic analysis confirmed its placement in that genus, as the second species of Elixia, and only the third member of family Elixiaceae. [1]
The brownish to greenish thallus of Elixia cretica is crustose, areolate, and thin (less than 50 μm thick); it lacks both soredia and isidia. It grows in the sheltered cracks of the bark. The ascomata of the lichen are in the shape of a lirella (an elongated, narrow apothecium) (lirelloid), measuring 0.5–1.4 mm in diameter with a black margin. Its ascospores, which number eight per ascus, are ellipsoid, colourless to faintly light brown, and have dimensions of 7.0–10.0 by 3.2–4.5 μm. No lichen products were detected in the lichen using thin-layer chromatography, and all of the standard chemical spot tests are negative. [1]
Coccotrema is a genus of lichen-forming fungi. It is the type genus of the family Coccotremataceae, in the order Pertusariales. The genus contains 16 species.
Kalbionora is a lichen genus in the family Malmideaceae containing the single crustose species Kalbionora palaeotropica. This lichen occurs in coastal forests in Thailand, Vietnam, and northeastern Australia, where it grows on tree bark.

Porpidia seakensis is a species of crustose lichen in the family Lecideaceae. It is an endolithic species, meaning it grows inside the rocks, between the grains. Found only in Alaska, it was formally described as a new species in 2020 by British lichenologist Alan Fryday. The type specimen was collected in the Hoonah-Angoon Census Area, in Glacier Bay National Park. Here it was discovered growing on granitic rock in a woodland. The lichen is only known from this area, although it is locally common. Its preferred habitat is siliceous rocks and boulders in wooded areas that are open and well lit. The specific epithet seakensis uses the letters "seak" to refer to a standard abbreviation for southeast Alaska.
Fuscopannaria dillmaniae is a species of lichen in the family Pannariaceae. Found in Alaska, it was described as a new species in 2020 by lichenologist Toby Spribille.
Sagiolechia phaeospora is a species of crustose lichen in the family Sagiolechiaceae. It is found in the alpine tundra of Alaska.
Lecidea streveleri is a species of crustose lichen in the family Lecideaceae. Found in Canada and the United States, it was described as a new species in 2020 by lichenologist Toby Spribille. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park (Alaska). Here it was on steep slopes in a basin on the west side of Dundas Bay, growing on the bark of an alder tree. The specific epithet streveleri honors Dr. Gregory P. Streveler, who, according to Spribille, is "an extraordinary naturalist and polymath, and author of numerous scientific papers, who has dedicated much of his life to understanding the natural history of Glacier Bay".
Ochrolechia cooperi is a species of crustose lichen in the family Ochrolechiaceae. Occurring only in southern Alaska, it was formally described as a new species in 2020 by lichenologist Toby Spribille. The type specimen was collected in the Hoonah-Angoon Census Area of Glacier Bay National Park, northeast of Gustavus. Here the lichen was found in muskeg growing on a conifer log that still had its bark. The specific epithet honors American ecologist William Skinner Cooper, "whose studies on plant succession in Glacier Bay and subsequent political lobbying efforts were influential in the establishment of Glacier Bay as a National Monument in 1925".
Leucodecton fuscomarginatum is a species of lichen in the family Graphidaceae. Found in Sri Lanka, it was formally described as a new species in 2014 by lichenologists Gothamie Weerakoon, Robert Lücking and Helge Thorsten Lumbsch. The type specimen was collected from the Kikiliyamana Tea Estate at an altitude of 1,280 m (4,200 ft). The lichen, which is known to occur only at the type locality, grows in disturbed vegetation. The specific epithet fuscomarginatum refers to the rims of the ascomata pores, which are typically brown in colour. Leucodecton fuscomarginatum has a shiny, smooth, light greenish to yellowish brown thallus measuring 50–100 μm thick with a thin cortex. The ascospores are muriform, ellipsoid in shape, and measure 30–40 by 10–12 μm. Secondary chemicals present in the lichen include stictic acid, constictic acid, acetylconstictic acid, and hypostictic acid.
Chrysothrix septemseptata is a species of crustose lichen in the family Arthoniaceae. Found in India, it was formally described as a new species in 2006 by T.A.M. Jagadeesh Ram, H. Thorsten Lumbsch, Robert Lücking, and G.P. Sinha. The type specimen was collected in the Sundarbans Biosphere Reserve ; here it was found growing on the bark of the mangrove tree Tamarix gallica. The lichen grows as a thin lemon-yellow crust measuring 0.5–2 cm (0.2–0.8 in) in diameter, with isolated patches sometimes coalescing. It contains vulpinic acid as a major secondary chemical, and minor amounts of calycin. Chrysothrix septemseptata is only known to occur at the type locality. Other mangrove trees that it is found on include Brugruiera gymnorhiza, Heritiera fomes, and Sonneratia apetala, as well as the non-mangrove tree Casuarina equisetifolia. The specific epithet septemseptata refers to the seven septa that are characteristic of the ascospores of this lichen.
Neoprotoparmelia paulii is a species of saxicolous (rock-dwelling), crustose lichen in the family Parmeliaceae. Found in Kenya, it was formally described as a new species in 2018 by Víctor Jiménez Rico, Helge Thorsten Lumbsch, and Garima Singh. The type specimen was collected in the Nuu Hills at an altitude of about 1,000 m (3,300 ft); here it was found growing on sandstone in an inselberg with dry woodland. The lichen is only known from the type locality, a montane ecosystem dominated by shrubs and trees from the genera Acacia, Combretum, and Terminalia. Neoprotoparmelia paulii contains several secondary compounds that can be detected using the technique thin-layer chromatography, including atranorin, α–collatolic acid, α–alectoronic acid, and traces of other chemically related substances. The specific epithet paulii honours Kenyan lichenologist Paul Kirika, who collected the type material along with Lumbsch.
