Ionaspis aptrootii is a species of saxicolous (rock-dwelling), crustose lichen in the family Hymeneliaceae. [3] It occurs in New Guinea and Thailand.
Ionaspis aptrootii is a replacement name for the taxon name Ionaspis tropica, which was published by the Dutch lichenologist André Aptroot in 1997. [1] That name was not validly published, as it was predated by another taxon of the same name, described by Lincoln Ware Riddle in 1920. [2] The new species epithet honours Aptroot, who originally described the species. [4] The type specimen was collected by Aptroot in Varirata National Park, Papua New Guinea, where he found it growing on conglomerate rock at an elevation of 700 m (2,300 ft). [1] It has since been recorded in Thailand. [5]
Ionaspis aptrootii has a smooth, cream-white thallus up to 1 mm thick and encircled with a black prothallus. It has angular to star-shaped ( stellate ), dark reddish-brown apothecia (fruiting bodies) that are immersed in the thallus, and measure 0.2–0.4 mm wide. Its ascospores , which number eight per ascus, are hyaline and ellipsoid, do not have septa, and measure 11–14 by 4–5 μm. The stellate, dark reddish-brown apothecia distinguish this species from others in the genus Ionaspis . [1]
The Graphidaceae are a family of lichen-forming fungi in the order Graphidales. The family contains nearly a hundred genera and more than 2000 species. Although the family has a cosmopolitan distribution, most Graphidaceae species occur in tropical regions, and typically grow on bark.
Punctonora is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed in 1997 by lichenologist André Aptroot, with Punctonora nigropulvinata assigned as the type species. A second species was added to the genus in 2018.
Traponora is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed in 2009 by Dutch lichenologist André Aptroot, with the Papua New Guinean Traponora asterella assigned as the type, and at that time, only species. Four newly described species were added to the genus in a 2009 publication, a species formerly in Pyrrhospora was transferred to the genus in 2017, and a new species from Australia added in 2018. Traponora lichens are predominantly from Australasia, with all species but one known to occur in Papua New Guinea.
Hippocrepidea is a genus of fungi in the family Gomphillaceae. This is a monotypic genus, containing the single species Hippocrepidea nigra.
André Aptroot is a Dutch mycologist and lichenologist. His primary research focus is on biodiversity, particularly tropical lichens, encompassing systematics, floristic surveys, and taxonomic reviews. A prolific researcher, he has published more than 500 scientific papers and described hundreds of new fungal and lichen species.
Hypotrachyna lueckingii is a species of corticolous (bark-dwelling), foliose lichen in the family Parmeliaceae. It is only known to occur at high elevations on the Cordillera de Talamanca in Costa Rica.
Aderkomyces thailandicus is a species of corticolous (bark-dwelling), crustose lichen in the family Gomphillaceae. Found in the lower montane rainforests of Thailand, it was described as new to science in 2011.
Byssoloma spinulosum is a species of foliicolous) (leaf-dwelling) lichen in the family Pilocarpaceae. Found in Papua New Guinea, it was described as new to science in 2011. It is characterized by its unique beaked pycnidia that are predominantly developed along the margins of living leaves.
Malmideaceae is a family of crustose and corticolous lichens in the order Lecanorales. It contains eight genera and about 70 species.
Neoprotoparmelia is a genus of crustose lichens that was created in 2018. It contains 24 tropical and subtropical species that mostly grow on bark. Neoprotoparmelia is in the subfamily Protoparmelioideae of the family Parmeliaceae, along with the morphologically similar genera Protoparmelia and Maronina.
Emmanuël Sérusiaux is a Belgian lichenologist. His career, spanning more than four decades, has combined both lichenology research and political aspects of nature conservation. He spent several periods working as a researcher at the National Fund for Scientific Research and the University of Liège, the latter in which he accepted a faculty position as professor and head of the Plant Taxonomy and Conservation Biology unit. Sérusiaux also served for three non-consecutive appointments as Deputy Chief of Staff in the Government of Wallonia. He retired from both his academic and political positions in 2019.
Coenogonium is a genus of filamentous lichens in the monotypic family Coenogoniaceae. It has about 90 species. Most species are leaf-dwelling or grow on bark, although a few are known to grow on rocks under certain conditions, and some are restricted to growth on termite nests. The genus was circumscribed in 1820 by German naturalist Christian Gottfried Ehrenberg.
Neoprotoparmelia capitata is a species of corticolous (bark-dwelling) and crustose lichen in the family Parmeliaceae. It is found in eastern North America.
Henricus (Harrie) Johannes Maria Sipman is a retired Dutch lichenologist who specialised in tropical and subtropical lichens and authored or co-authored over 250 scientific publications. He was the curator of the lichen herbarium at the Berlin Botanical Garden and Botanical Museum from 1983 until his retirement in 2010.
Alyxoria viridipruinosa is a species of corticolous (bark-dwelling) and lignicolous (wood-dwelling) lichen in the family Lecanographaceae. It is found in Europe, where it grows on hardwood trees.
Pertusaria thailandica is a species of corticolous (bark-dwelling), crustose lichen in the family Pertusariaceae. Found in Thailand, it was formally described as a new species in 2005 by Sureeporn Jariangprasert. The type specimen was collected by the author from Doi Suthep–Pui National Park at an altitude of 1,100 m (3,600 ft), where it was found growing on the bark of Cinchona. The species epithet combines the country of the type locality with the Latin suffix -ensis.
Ionaspis is a genus of lichen-forming fungi in the family Hymeneliaceae. It contains six species of saxicolous (rock-dwelling), crustose lichens. The genus was originally circumscribed in 1871 by Theodor Magnus Fries. He segregated the genus from Aspicilia based on the presence of Trentepohlia rather than Trebouxia as the photobiont partner.
Megalotremis is a genus of lichen-forming fungi in the family Monoblastiaceae. It has 16 species. The genus was circumscribed by Dutch lichenologist André Aptroot in 1991, with Megalotremis verrucosa assigned as the type species. Megalotremis is a pyrenolichen genus, meaning its species have perithecioid ascocarps: spherical or flask-shaped, sessile or partly immersed in the thallus, with a single opening (ostiole) and enclosed by a distinct wall.
Gassicurtia omiae is a species of corticolous (bark-dwelling), crustose lichen in the family Caliciaceae. Found in Thailand, it was formally described as a new species in 2009 by lichenologist Klaus Kalb. The species epithet omiae honours Mrs. W. Saipunkaew ("Om"), who assisted the author as a guide and discovered the species in the field. Gassicurtia omiae is the first species of Gassicurtia with a sorediate thallus and the first that produces the lichen product 6-O-methylarthothelin.
Phaeographopsis is a genus of script lichens in the family Graphidaceae. It has three species.
