Lithophytes are plants that grow in or on rocks. They can be classified as either epilithic or endolithic; epilithic lithophytes grow on the surfaces of rocks, while endolithic lithophytes grow in the crevices of rocks. Lithophytes can also be classified as being either obligate or facultative. Obligate lithophytes grow solely on rocks, while facultative lithophytes will grow partially on a rock and on another substrate simultaneously.
The Pertusariaceae are a family of lichen-forming fungi in the order Pertusariales.
Lasioloma is a genus of lichenized fungi in the family Pilocarpaceae. The genus was circumscribed by Swedish lichenologist Rolf Santesson in 1952, with Lasioloma arachnoideum assigned as the type species. Found predominantly in tropical rainforests, genus Lasioloma contains both foliicolous (leaf-dwelling) and corticolous (bark-dwelling) species. The foliicolous species are distinguished by their woolly prothallus, a thallus that ranges from dispersed to continuous, and a hairy apothecial margin. In contrast, corticolous species typically do not have a woolly prothallus, and their thalli are usually continuous, or unbroken. Regardless of the substrate they inhabit, all known Lasioloma species are characterized by the production of campylidia and branched conidia.
Badimiella is a genus of lichen-forming fungi in the family Pilocarpaceae. It has two species of foliicolous (leaf-dwelling) lichens.
Coccomyces is a genus of fungi in the family Rhytismataceae.
Calenia is a genus of lichen-forming fungi within the family Gomphillaceae.
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.
Tricharia vainioi is a species of foliicolous lichen in the family Gomphillaceae. It is widely distributed, having been recorded in Africa, Asia, Australia, Central and South America.
Rolf Santesson (1916–2013) was a Swedish lichenologist and university lecturer. He was awarded the Acharius Medal in 1992 for his lifetime contributions to lichenology.
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.
Bapalmuia serusiauxiana is a species of foliicolous lichen in the family Pilocarpaceae. Found in the Democratic Republic of the Congo, it was described as a new species in 2014 by Dries Van den Broeck, Robert Lücking, and Damien Ertz. The type specimen was collected in Mbangi, about 20 km (12 mi) upstream of Lisala, on the left bank of the Congo River. There, it was found growing on leaves in an old secondary forest. The specific epithet honours Belgian lichenologist Emmanuël Sérusiaux, "an outstanding figure in foliicolous lichen research, especially in tropical Africa".
Strigulaceae is a family of lichen-forming fungi, one of two families in the order Strigulales. Recent (2020) molecular analysis of the type genus, Strigula, has led to a reallocation of the foliicolous species into six genera that correspond to well-delimited clades with diagnostic phenotype features.
Mazosia lueckingii is a species of foliicolous (leaf-dwelling) lichen in the family Roccellaceae. Found in India, it was formally described as a new species in 2008 by Krishna Pal Singh and Athokpam Pinokiyo. The type specimen was collected by the first author in the Darjeeling district at an altitude of 1,200 m (3,900 ft), where it was found growing on dicotyledon leaves. The lichen has a verrucose (warty) thallus with brown, hairless verrucae, a black hypothallus, and ascospores that measure 34–45 by 4–7 μm with 4 or five septa. The specific epithet lueckingii honours German-born lichenologist Robert Lücking, who, according to the authors, "has made remarkable contributions to the taxonomy and ecology of foliicolous lichens".
Thelenella indica is a species of foliicolous (leaf-dwelling) lichen in the family Thelenellaceae. Found in India, it was formally described as a new species in 2006 by Athokpam Pinokiyo and Krishna Pal Singh. The type specimen was collected by the first author in a tropical forest along the Assam-Linzey road in the East Sikkim district; here it was found growing on the leaves of a small Schima wallichii tree. It appears to be endemic to the Sikkim region of India.
Phylloblastia is a genus of foliicolous (leaf-dwelling) lichens in the family Verrucariaceae. The genus was circumscribed in 1921 by Finnish lichenologist Edvard August Vainio, with Phylloblastia dolichospora assigned as the type species.
Phylloblastia bielczykiae is a species of foliicolous (leaf-dwelling) lichen in the family Verrucariaceae. Found in Bolivia, it was formally described as a new species in 2008 by lichenologists Adam Flakus and Robert Lücking. The type specimen was collected near lake Copaiba ; there, in an isolated island of lowland Amazon rainforest along a savanna, it was found growing on the leaves of a vascular plant. It is only known from the type locality. The species epithet honours the Polish lichenologist Urszula Bielczyk.
Porina weghiana is a rare species of foliicolous (leaf-dwelling) lichen in the family Porinaceae. Found in the Democratic Republic of the Congo, it was formally described as new to science in 2014 by Dries Van den Broeck, Robert Lücking, and Damien Ertz. The type specimen was collected in the valley of Loika at an altitude of 350 m (1,150 ft), where it was found growing on palm tree leaves along the river. It is only known to occur in the type locality. It resembles Porina ornata in appearance but differs in having disc-shaped isidia, yellow perithecia lacking apical appendages, and ascospores that are smaller and have fewer septa. The species epithet is named after the first author's girlfriend, Micheline Wegh.
Tenuitholiascus is a fungal genus in the monotypic family Tenuitholiascaceae, itself in the order Strigulales. The genus contains a single species, Tenuitholiascus porinoides, a foliicolous (leaf-dwelling) lichen found in China.
Robert Lücking is a German lichenologist. He earned his master's and PhD from the University of Ulm, focusing on the taxonomy, ecology, and biodiversity of foliicolous lichens. He has received numerous awards for his work, including the Mason E. Hale Award for his doctoral thesis, the Augustin Pyramus de Candolle prize for his monograph, and the Tuckerman Award twice for his publications in The Bryologist. Since 2015, he has been serving as the curator of lichens, fungi, and bryophytes at the Berlin Botanical Garden and Botanical Museum, and several lichen species and a genus have been named in his honour.
Podotara is a fungal genus in the family Pilocarpaceae. It is a monotypic genus, containing the single species Podotara pilophoriformis, an uncommon foliicolous (leaf-dwelling), crustose lichen that grows on Podocarpus totara, a species of podocarp tree endemic to New Zealand. Both the genus and the species were proposed in 1996.
