Tiina Randlane (born 10 September 1953) is an Estonian mycologist and lichenologist. [1]
Randlane was born in Tallinn and completed her undergraduate studies at Tartu State University, graduating cum laude in 1977. She pursued further education at the same institution, obtaining her candidate's degree in 1986. Her thesis explored the lichen flora of Estonia's western islands. Randlane's professional journey at the University of Tartu began in 1975 when she started as a technician. She has maintained her affiliation with the university throughout her career, progressing to her current position as an associate professor. [2]
Randlane's research primarily concentrates on lichen taxonomy and ecology. Her publication record includes close to a hundred scientific papers and book chapters. One of her notable contributions is spearheading the development of a comprehensive global taxonomic database for cetrarioid lichens. A significant portion of her work has been dedicated to studying the lichen biodiversity of Estonia and the broader Baltic region. [2]
Throughout her career, Randlane has been instrumental in compiling Estonia's Red Data Books and subsequent Red Lists of Lichens. She served on the editorial board of Folia Cryptogamica Estonica for over two decades, from 1996 to 2020. In 2020, she took on the role of associate editor for the journal The Lichenologist . [2]
Beyond her research endeavors, Randlane has played a pivotal role in shaping Estonian lichenology. Her engaging lectures and field courses have inspired numerous students, fostering a new generation of lichen enthusiasts. She has also been committed to making lichen knowledge accessible to the public, co-authoring a multilingual series on Estonian macrolichens for a general audience. Randlane has contributed significantly to the development of online educational resources covering Estonian lichens, mosses, and vascular plants. Additionally, she has been actively involved in expanding the lichen herbarium at the University of Tartu, adding nearly 7,000 specimens that she collected and identified. [2]
Randlane's contributions have been recognised with several accolades from the University of Tartu. She received the university medal in 2003, followed by the medal of honour a decade later in 2013. In 2021, she was awarded a special medal commemorating "100 semesters at the University of Tartu". Her efforts in science communication were acknowledged in 2010 when interactive online identification guides she helped develop won the top prize for innovative science popularisation in Estonia. In recognition of her significant contributions to the field, the 60th issue of Folia Cryptogamica Estonica was dedicated to Randlane on the occasion of her 70th birthday. [2] The lichen species Pyxine tiinae , [3] Leptogium tiinae , [4] and Lepraria tiinae were named in her honour in this issue. [5]
Calenia is a genus of lichen-forming fungi within the family Gomphillaceae.
Parmelia asiatica is a species of corticolous (bark-dwelling) foliose lichen in the family Parmeliaceae. It was described as new to science in 2011 by lichenologists Ana Crespo and Pradeep Divakar, based on specimens from Yunnan, China. Since then, its known distribution has expanded to include various regions of Russia, parts of North America, and as of 2024, European Russia. The species is found in the forests of temperate and boreal climates, growing on the bark of various tree species. Parmelia asiatica is distinguished by its small thallus with narrow, more or less linear lobes, soralia that appear at the ends of the lobes, marginal linear pseudocyphellae, and a chemical composition that includes atranorin, salazinic acid, and consalazinic acid. While similar to other Parmelia species, it can be differentiated from them by its morphological and chemical characteristics.
Melaspilea is a genus of lichen-forming and lichenicolous fungi in the family Melaspileaceae. The genus was circumscribed by Finnish lichenologist William Nylander in 1857.
Muellerella lichenicola is a species of lichenicolous fungus in the family Verrucariaceae. It was first formally described as a new species in 1826 by Søren Christian Sommerfelt, as Sphaeria lichenicola. David Leslie Hawksworth transferred it to the genus Muellerella in 1979.
Lichenopeltella cetrariae is a species of fungus belonging to the class Dothideomycetes. It has been found growing on Cetraria aculeata in Hrútey near Blönduós, Iceland and on Cetraria laevigata in Bulgan district, Mongolia and Toyama prefecture, Japan. In Japan, it has also been reported growing on Flavocetraria cucullata in Yamanashi prefecture and Nagano prefecture.
Lepraria incana is a species of dust lichen in the family Stereocaulaceae. First described scientifically by Johann Jacob Dillenius in 1741, and then formally by Carl Linnaeus in 1753, it is the type species of the genus Lepraria. The thallus of this species is green to greyish-green, and powdery – as if made of tiny granules. These granules are soredia, which are asexual reproductive structures. Like most members of genus Lepraria, the lichen has few distinguishing features, lacking both a medulla and sexual reproductive structures (apothecia). Chemically, the lichen is characterised by the presence of the secondary chemicals known as divaricatic acid and zeorin.
Parmelia fraudans is a species of foliose lichen in the family Parmeliaceae. It is found in Europe and North America, where it grows on rocks.
Lepraria salazinica is a species of rock-dwelling, leprose lichen in the family Stereocaulaceae. It is found in the eastern United States.
Candelariella aggregata is a species of lichen in the family Candelariaceae. It is found in western North America, Mongolia, and Switzerland where it grows on mosses and plant debris.
Candelaria pacifica is a widely distributed corticolous (bark-dwelling), leprose lichen. It was formally described as a species in 2011.
Endococcus hafellneri is a species of lichenicolous (lichen-eating) fungus in the family Verrucariaceae. It is found in North Asia and the Russian Far East, Estonia, and Japan, where it grows on the lobes of the lichens Flavocetraria cucullata and Cetraria islandica.
Bacidina pycnidiata is a species of crustose lichen in the family Ramalinaceae. It is widely distributed in Europe and North Asia. It is characterised by its whitish or cream-coloured pycnidia with long and ostiolar necks.
Lichenopeltella coppinsii is a species of lichenicolous fungus belonging to the class Dothideomycetes. It was described in 1999. It is known to infect Verrucaria muralis and has been reported from the British Isles, Ukraine, and Moshchny Island in the Baltic sea.
Xanthoparmelia angustiphylla is a foliose lichen that belongs to the genus Xanthoparmelia.
Cetraria laevigata is a species of ground-dwelling, fruticose (bushy) lichen in the family Parmeliaceae. It was formally described as a new species by Russian lichenologist Kseniya Aleksandrovna Rassadina in 1943. In North America, it is commonly known as the striped Iceland lichen.
Calogaya arnoldii is a species of saxicolous (rock-dwelling), crustose lichen that is common and widespread in Europe and Asia. It is in the family Teloschistaceae. It was first formally described as a new species in 1876 by Hugh Algernon Weddell, as a species of Lecanora. After being transferred to Caloplaca in 1915, it was considered as a member of that genus for nearly a century. Molecular phylogenetic studies showed Caloplaca to be polyphyletic, and it was divided up into several smaller genera in 2013. Calogaya arnoldii was one of eight species transferred to the newly circumscribed Calogaya by Ulf Arup, Patrik Frödén, and Ulrik Søchting. The lichen is part of a species complex with complicated taxonomy, and in which intermediate phenotypes are frequently observed, making it difficult to reliably distinguish them. Calogaya saxicola is one such similar species, and it has often been confused with C, arnoldii in areas where they co-occur, as the differences between them are subtle.
Flavoplaca arcis is a species of saxicolous (rock-dwelling), crustose to squamulose (scaley) lichen in the family Teloschistaceae. Although widely distributed in Northern, Central, and Western Europe, it is not commonly encountered.
Xanthoria calcicola is a species of saxicolous and corticolous, crustose lichen in the family Teloschistaceae.
Peltigera castanea is a species of terricolous and muscicolous, foliose lichen in the family Peltigeraceae. Described as a new species in 2003, it is part of the taxonomically challenging species complex centred around Peltigera didactyla. Recognised based on phylogenetic studies that highlighted its unique genetic markers, P. castanea is distinguished by its dark, chestnut-coloured upper surface, which inspired its vernacular name, chestnut pelt lichen. Its known distribution includes North America, Asia, Europe (Estonia), Greenland, and the Antarctic. The conservation status of Peltigera castanea varies regionally, from being critically imperiled in British Columbia and Yukon to critically endangered in Estonia due to significant habitat degradation and restricted population size.
Lecanora perpruinosa is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecanoraceae. It occurs in Northern Europe, Estonia, Turkey, Russia, and Canada, where it grows on calcareous rocks.
