Pallidogramme is a genus of lichen-forming fungi in the family Graphidaceae. [2] It has 8 species of corticolous (bark-dwelling), crustose lichens.
Pallidogramme was proposed in 2008 by lichenologists Betsy Staiger, Klaus Kalb, and Robert Lücking, as a replacement name for LeucogrammaA.Massal. The justification for this change originated from the previously established Hemithecium subgen. Leucogramma by Staiger in 2002. There was, however, a pre-existing generic name, LeucogrammaA.Massal., which was based on the same species as Staiger's subgenus, Hemithecium chrysenteron. Both of these names were unusable at the genus level due to their homonymy with LeucogrammaG.Mey. a name with unknown taxonomic affinity. As a result, a new name was deemed necessary to avoid confusion and maintain nomenclatural clarity. [3]
The defining features of genus Pallidogramme include a crust-like, bark-dwelling thallus, fully formed labia, a predominantly inspersed hymenium, and an exciple which is non- carbonized , displaying a spectrum of colours from pale yellowish-brown to reddish-brown, accompanied by internal striations. Moreover, it possesses ascospores that range in colour from pale brown to brown, and that turn reddish-brown when stained with iodine (I+). [4]
Pallidogramme indica was proposed as a new species from India in 2009, [8] but it was not published validly; [9] a similar situation occurs with the proposed Pallidogramme undulatolirellataA.Dube & Makhija. [10]
Former Pallidogramme species:
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.
Platythecium is a genus of lichen-forming fungi in the family Graphidaceae. It contains an estimated 27 species.
Platygramme is a genus of lichen-forming fungi in the family Graphidaceae consisting of about 30 species. The genus was circumscribed by Antoine Laurent Apollinaire Fée in 1874.
Graphis is a genus of lichen-forming fungi in the family Graphidaceae.
Fissurina is a genus of lichenized fungi in the family Graphidaceae. It has about 160 species, most of which are found in tropical regions.
Diorygma is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Franz Gerhard Eschweiler in 1824. Species of the genus are widely distributed in tropical and subtropical regions of the world.
Carbacanthographis is a genus of corticolous (bark-dwelling) lichens in the family Graphidaceae. The genus was circumscribed by German lichenologists Bettina Staiger and Klaus Kalb in 2002. An updated worldwide key to the genus was published in 2022 that added 17 new species.
Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909.
Acanthotrema is a genus of lichens in the family Graphidaceae. The genus was circumscribed by German lichenologist Andreas Frisch in 2006, with Acanthotrema brasilianum assigned as the type species. Acanthotrema species are commonly found in rainforests ranging from lowland to montane environments.
André Aptroot is a Dutch mycologist and lichenologist.
Allographa is a genus of script lichens in the family Graphidaceae. It has nearly 200 species. Formally circumscribed in 1824 by François Fulgis Chevallier, Allographa was formerly included in Graphis, but was upgraded to generic status in 2018 by lichenologists Klaus Kalb and Robert Lücking.
Kalbographa is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2007 by lichenologist Robert Lücking with Kalbographa caracasana assigned as the type species. The genus name honours German lichenologist Klaus Kalb.
Rhabdodiscus is a genus of script lichens in the family Graphidaceae. It has 36 species.
Henricus (Harrie) Johannes Maria Sipman is a Dutch lichenologist. He specialises in tropical and subtropical lichens, and has authored or co-authored more than 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.
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.
Graphidales is an order of lichen-forming fungi in the class Lecanoromycetes. It contains 6 families, about 81 genera and about 2,228 species. Family Graphidaceae are the largest crustose family within Graphidales order comprising more than 2000 species, which are widely distributed in tropical and subtropical regions of the world.
Leiorreuma is a genus of script lichens in the family Graphidaceae. It has 18 species. The genus was circumscribed by Franz Gerhard Eschweiler in 1824, with Leiorreuma hepaticum assigned as the type species.
Graphis flavovirens is a species of script lichen in the family Graphidaceae. Found in the Andaman Islands, it was formally described as a new species in 2005 by Urmila Makhija and Bharati Adawadkar. The type specimen was collected from Parlobjig. The species epithet "flavovirens", which combines the Latin words for yellow and green, refers to the colour of the thallus. Its ascomata are in the form of conspicuous lirellae: they are long and black, with a branching pattern ranging from simple to radiately and profusely branched; this particular branching pattern is known as the centrifuga-morph. G. flavovirens produces ellipsoidal ascospores that have from 3 to 9 transverse septa and measure 16–42 by 4–8 μm. G. flavovirens contains two lichen products: stictic acid and constictic acid.
Graphis palmicola is a species of script lichen in the family Graphidaceae. Found on the Nicobar Islands, it was formally described as a new species in 2005 by Urmila Makhija and Bharati Adawadkar. The type specimen was collected from a beach forest in Katchal Island, where it was found growing on a coconut tree. The species epithet, which combines the Latin Palma and cola ("exists"), refers to its host. The ascomata of the lichen are in the form of lirellae, which are elongated and irregularly branched; this particular branching pattern is known as the handelii-morph.
