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, [2] which are widely distributed in tropical and subtropical regions of the world. [3]
The Graphidales were introduced in a 1884 publication by Frigyes Ákos Hazslinszky in Magyar Birodalom Zuzmó-Flórája on page 216 as family Graphideae. [1] In 1907, they were established as an order by American botanist Bessey (1845–1915), [4] [5] [6]
When the order was introduced, it contained just two families, the Graphidaceae and Thelotremataceae who were both mainly tropical based and each family had about 800–1000 species. [7]
Sherwood in 1977 proposed to maintain a distinction between the Graphidales with mostly lichenised members and the Ostropales which included mostly non-lichenised fungi, based on different spore septation types. [8]
Molecular data by Winka et al. in 1998, supported a close relationship between the two groups of species. [9] [10]
The Graphidales were then included in the Ostropales order (Lecanoromycetes) for a long time (Staiger 2002; [11] Kalb et al. 2004; [12] Hibbett et al. 2007; [13] Lumbsch et al. 2007; [14] Kirk et al. 2008; [15] Baloch et al. 2010; [16] Rivas Plata and Lumbsch 2011; [17] Rivas Plata et al. 2012; [18] Lumbsch et al. 2014; [19] Lücking et al. 2017; [20] Wijayawardene et al. 2018). [21]
In 2004, the phylogenetic relationships of class Lecanoromycetes were examined by using mitochondrial small subunit ribosomal DNA sequencing which found that orders Graphidales and Ostropales were monophyletic. [22]
Using molecular data (partial DNA sequencing) in 2012, it was also shown that Graphidaceae and Thelotremataceae were non-monophyletic and consequently Thelotremataceae was included in Graphidaceae as a synonym. [23] Graphidaceae also included subfamilies Fissurinoideae and Graphidoideae. [24] [25]
However, Kraichak et al. in 2018, [26] ranked Graphidales as a separate order based on a temporal approach, and accepted five families; Diploschistaceae, Fissurinaceae, Gomphillaceae, Graphidaceae and Thelotremataceae. [27] [28] Wijayawardene et al. 2020 agreed but also added family Redonographaceae to the order, [2] Other authors have agreed on the use of reinstated order of Graphidales. [3] [29] [30] [31]
Most species in the order are lichens which have a thallus (vegetative tissue) which is crustose and ascocarps (fruiting body) which are apothecioid (cup-shaped). [32] [33]
The Graphidaceae are mostly epiphytic lichens with trentepohlioid photobiont (i.e., filamentous, multicellular green algae from genus Trentepohlia ), [34] and graphidoid, distoseptate (forming a layer) ascospores. [35] [36]
Family Gomphillaceae was originally based on a single species, Gomphillus calycioides (Watson, 1929), which is an unusual taxon growing over bryophytes. [37]
It includes a common asexual fungus Lawreya glyphidiphila (Teratosphaeriaceae family) which is described as growing on lichenized fungi Glyphis scyphulifera (Graphidaceae family). [29]
They are mainly found in warmer regions living on bark. [32] Genera in the order of Graphidales has been found worldwide, [38] from North America (including Florida, [29] [39] ), South America (including Venezuela, [40] Costa Rica, [41] and Guianas, [42] ), Africa (including Kenya, [43] and South Africa, [44] ), Asia (including China, [31] [45] Vietnam, [46] Sri Lanka, [47] India, [3] [48] and Thailand, [49] ) Australia, [50] [51] and also New Zealand. [5] [52]
Species of family Gomphillaceae are found in north-eastern Brazil, Mexico, Guatemala, Costa Rica, Panama and Cuba. [37]
This is a list of the families and genera contained within the Graphidales, based on a 2020 review and summary of ascomycete classification. [2] Following the taxon name is the taxonomic authority, year of publication, and (for genera) the number or estimated number of 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.
Gymnographopsis is a genus of lichen-forming fungi in the family Redonographaceae.
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.
Acanthothecis is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed by Frederick Edward Clements in 1909.
Chapsa is a genus of lichens in the family Graphidaceae. The genus was circumscribed by Italian lichenologist Abramo Bartolommeo Massalongo in 1860.
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.
Thelotrema is a genus of lichen-forming fungi in the family Graphidaceae, the family to which all taxa in the former Thelotremataceae now belong.
Astrochapsa is a genus of lichen-forming fungi in the subfamily Graphidoideae of the family Graphidaceae. It has 28 species. The genus was circumscribed by Sittiporn Parnmen, Robert Lücking, and H. Thorsten Lumbsch in 2012, with Astrochapsa astroidea assigned as the type species. It was segregated from the genus Chapsa, from which it differs in having a more frequently densely corticate thallus, an apothecial margin that is mostly recurved, and the almost exclusively subdistoseptate, non-amyloid ascospores.
Wirthiotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2010 by Eimy Rivas Plata, Klaus Kalb, Andreas Frisch, and H. Thorsten Lumbsch, with Wirthiotrema glaucopallens assigned as the type species. Wirthiotrema contains species that were formerly considered part of the Thelotrema glaucopallens species group. The genus name honours lichenologist Volkmar Wirth, "for his numerous outstanding contributions to lichenology".
Rhabdodiscus is a genus of script lichens in the family Graphidaceae. It has 36 species.
Schizotrema is a genus of lichen-forming fungi in the family Graphidaceae. The genus was circumscribed in 2009 by Armin Mangold and H. Thorsten Lumbsch.
Pseudochapsa is a genus of lichen-forming fungi in the family Graphidaceae. It has 19 species. It was circumscribed in 2012 by Sittiporn Parnmen, Robert Lücking, and Helge Thorsten Lumbsch, with Pseudochapsa dilatata as the type species. Pseudochapsa differs from Chapsa it that its excipulum is typically brown. Additionally, its ascospores are mostly discoseptate and amyloid. The generic name combines the Greek pseudo ("false") with the genus name Chapsa.
Cruentotrema is a genus of corticolous (bark-dwelling) lichens in the family Graphidaceae. It has seven species.
Clandestinotrema is a genus of lichen-forming fungi in the family Graphidaceae. It has 17 species. They typically inhabit montane and cloud forest at higher elevations in the tropics.
Topeliopsis acutispora is a species of crustose lichen in the family Graphidaceae. It is found in New South Wales and southern Queensland (Australia), where it grows on bryophytes.
Gintarasia is a genus of lichen-forming fungi in the family Graphidaceae. It has seven species, all of which are found in Australia. Gintarasia species are corticolous (bark-dwelling), crustose lichens with a thelotremoid form.
Pycnotrema is a small genus of lichen-forming fungi in the family Graphidaceae. Its two species are characterised by their small, rounded apothecial pores.
Glaucotrema is a genus of lichen-forming fungi in the family Graphidaceae. It has five species.
