Trichothelium is a genus of lichen-forming fungi in the family Porinaceae. It has an estimated 40 species. The genus was circumscribed by the Swiss lichenologist Johannes Müller Argoviensis in 1885, with Trichothelium epiphyllum assigned as the type species.
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.
Byssoloma is a genus of leaf-dwelling lichens in the family Pilocarpaceae.
Badimiella is a genus of lichen-forming fungi in the family Pilocarpaceae. It has two species of foliicolous (leaf-dwelling) lichens.
Tapellaria is a genus of leaf-dwelling lichens in the family Pilocarpaceae. The genus was circumscribed by lichenologist Johannes Müller Argoviensis in 1890, with Tapellaria herpetospora assigned as the type species.
Coccomyces is a genus of fungi in the family Rhytismataceae.
Coccomyces dentatus is a species of fungus in the family Rhytismataceae. A widespread species, particularly in temperate areas, it colonizes the dead fallen leaves of vascular plants, particularly oak and chestnut. The fungus apothecia, which form in the epidermal layer of the leaf host, resemble dark hexagonal spots scattered on a multi-colored mosaic pattern bounded by thin black lines. When mature, the apothecia open by triangular flaps to release spores. The anamorph form of C. dentatus is Tricladiopsis flagelliformis. Lookalike species can be distinguished by the shape of the apothecia, or by microscopic characteristics.
A foliicolous lichen is a lichen which grows on the surfaces of living leaves of vascular plants, usually inhabiting the upper surface (epiphyllous) but sometimes also the lower surface (hypophyllous). Foliicolous lichens largely occur in tropical environments and of the over 800 foliicolous lichens accepted over 600 of these are known from the tropics. Unlike most lichens which are common in humid but cool and temperate climates, these tropical lichens are more suited to the higher temperatures and lower light levels present beneath the rainforest canopy, where they are involved in the nutrient cycle and water retention. Chlorophyta are common photosynthetic partner phycobionts of epiphyllous lichens.
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.
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".
Asterina stipitipodia is a species of fungus in the family Asterinaceae, first described by Marie Leonore Farr in 1987. It was originally found on the leaves of Dilleniaceae species in Brazil, South America,
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.
Robert Lücking is a German lichenologist, known for his extensive research on foliicolous lichens and his significant contributions to the taxonomy, ecology, and biodiversity of fungi and lichens. He earned his master's and PhD from the University of Ulm, focusing on 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 scientific journal The Bryologist.
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.
Enterographa bella is a species of foliicolous (leaf-dwelling) lichen in the family Roccellaceae. The lichen is characterised by its orange-brown, often wavy lirellae. Its photobiont partner is from the green algal genus Phycopeltis.
