Cratiria sorediata is a species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. [1] It was first described as a new species in 2009. The type specimen was collected from Aldabra in the Seychelles.
Cratiria sorediata was described as a new species by the lichenologists André Aptroot and Mark Seaward in 2009. The type specimen was collected in 1973 from Cinque Cases, Aldabra, where it was found growing on dead Pemphis . The species is notable for being the first in the genus Cratiria to have both soredia and the lichen product norstictic acid. [2]
Cratiria sorediata has a slightly shiny, corticate thallus that is smooth and pale ochraceous grey, covering an area of up to 3 cm (1.2 in) in diameter. Soredia are formed in roundish, shallow soralia , later covering much of the thallus, and are ochraceous yellow in colour. [2]
Apothecia (fruiting bodies) of Cratiria sorediata are sessile , round to wavy in outline, saucer-shaped, and measure 0.3–0.5 mm in diameter. The disc of the apothecia is black, shiny, and flat, without pruina . The margin of the apothecium is prominent, raised above the disc; it is black and shiny, measuring about 0.1 mm wide. The excipulum is about 75 µm wide, black on the outside, dark brown to pale brown inside, and with crystals and lumina about 10 µm wide. The hypothecium is dark brown, measuring about 20–30 µm high. The hymenium is not inspersed and measures about 70–90 µm high, with an epihymenium consisting of brown caps of paraphyses without crystals, about 4 µm high, and K− in reaction. The ascospores are ellipsoid , have a single septum, brownish-black, measuring 13–15 by 7–8 µm, and are not ornamented. [2]
The species contains norstictic acid. This results in the thallus and soredia turning K+ (red) in chemical spot tests. [2]
Cratiria sorediata is known to occur only at the type locality in Aldabra, Seychelles. It grows on the bark of coastal trees and shrubs. [2]
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.
Hypogymnia flavida is a species of foliose lichen in the family Parmeliaceae. It is found in mountainous locations of east Asia, where it grows on the bark and wood of woody plants. It has a relatively large yellowish thallus.
Astrothelium macroeustomum is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. Found in French Guiana, it was formally described as a new species in 2019 by lichenologists André Aptroot and Harrie Sipman. The type specimen was collected by Sipman from the Piste Crique Limonade at an altitude of 300 m (980 ft). The lichen has a mostly smooth, pale ochraceous-brown thallus that is somewhat shiny and covers areas up to 9 cm (4 in) in diameter. It is surrounded by a dark brown prothallus. It has pear-shaped (pyriform) ascomata, measuring 0.6–1.0 mm in diameter, which mostly aggregate in groups of two to five, and are more or less immersed in the tissue of the bark, below the thallus surface. They have convex, black ostioles (pores) that are surrounded by a yellowish-white ring of pruina. The ascospores are hyaline, spindle-shaped (fusiform) with five septa and measure 50–55 by 12–17 μm. The lichen contains lichexanthone, a lichen product that causes the ostioles of the ascomata to fluoresce yellow when lit with a long-wavelength UV light. The specific epithet macroeustomum refers to both its large spores and its similarity to Astrothelium eustomum.
Psora taurensis is a species of terricolous (ground-dwelling), squamulose lichen in the family Lecanoraceae. It is found in the Taurus Mountains of Turkey.
Astrothelium philippinense is a species of corticolous (bark-dwelling), crustose lichen in the family Trypetheliaceae. Found in the Philippines, it was formally described as a new species in 2016 by lichenologists André Aptroot and Felix Schumm. The type specimen was collected from Mount Talinis at an altitude between 1,100 and 1,600 m ; there, it was found in a rainforest growing on smooth tree bark. The lichen has a smooth and shiny, pale ochraceous-green thallus with a cortex and a thin brown to black prothallus line. It covers areas of up to 7 cm (2.8 in) in diameter. The presence of the lichen induces galls in the host plant, leading to the formation of numerous wart-like structures about 1–2 mm wide. No lichen products were detected in collected samples of the lichen using thin-layer chromatography. The combination of characteristics of the lichen that distinguish it from others in Astrothelium are the bullate, gall-like thallus; and the ascomata that are immersed in large thallus verrucae that are covered by thallus. The ascospores of A. philippinense number four per ascus. They are hyaline, ellipsoid, and muriform, with dimensions of 125–170 by 30–35 μm.
Pertusaria galapagoensis is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Elix, Yánez-Ayabaca, A.W.Archer & Bungartz. The type specimen was collected on Floreana Island at an altitude of 371 m (1,217 ft), where it was found growing on the bark of a south-exposed trunk of Cedrella odorata. The species epithet refers to its distribution.
Pertusaria albineoides is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found on the Galápagos Islands, it was formally described as a new species in 2015 by Frank Bungartz, A.W.Archer, Alba Yánez-Ayabaca, and John Elix. The type specimen was collected on Alcedo Volcano at an altitude of 1,089 m (3,573 ft), where it was found growing on a partially shaded, rain- and wind-exposed trunk of Scalesia microcephala. The species epithet refers to the similarity to the species Pertusaria albinea, from which it differs by having thin-walled ellipsoid-shaped ascospores that are longer and narrower.
Enterographa rotundata is a species of corticolous (bark-dwelling) crustose lichen in the family Roccellaceae. This species was discovered in Brazil, growing on the smooth bark of trees in the Brazilian Caatinga forest. It has round apothecia, a feature that sets it apart from most of its kind.
