Graphidales Genera
Graphidales is an order (biology), order of lichen-forming fungi in the class Lecanoromycetes. It contains 6 family (biology), families, about 81 genus, 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. History The Graphidales were introduced in a 1884 publication by Frigyes Ákos Hazslinszky in Magyar Birodalom Zuzmó-Flórája on page 216 as family Graphideae. In 1907, they were established as an Order (biology), order by American botanist Charles Edwin Bessey, Bessey (1845–1915), 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. Sherwood in 1977 proposed to maintain a distinction between the Graphidales with mostly lichenised members and the Ostropales which included mostl ...

Pallidogramme Chrysenteron
''Pallidogramme'' is a genus of lichen-forming fungi in the family Graphidaceae. It has 8 species of corticolous lichen, corticolous (bark-dwelling), crustose lichens. Taxonomy ''Pallidogramme'' was proposed in 2008 by the lichenologists Bettina Staiger, Klaus Kalb, and Robert Lücking, as a replacement name for ''Leucogramma'' . 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, ''Leucogramma'' , 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 Homonym (biology), homonymy with ''Leucogramma'' a name with unknown taxonomy (biology), taxonomic affinity. As a result, a new name was deemed necessary to avoid confusion and maintain nomenclatural clarity. Description The defining features of genus ''Pallidogramme'' include a crustose lichen, cr ...

Crustose
Crustose is a Habit (biology), habit of some types of algae and lichens in which the organism grows tightly appressed to a substrate, forming a biological layer. ''Crustose'' adheres very closely to the Substrate (biology), substrates at all points. ''Crustose'' is found on Rock (geology), rocks and Bark (botany), tree bark. Some species of marine algae of the Rhodophyta, in particular members of the Order (biology), order Corallinales, Family (biology), family Corallinaceae, subfamily Melobesioideae with cell walls containing calcium carbonate grow to great depths in the intertidal zone, forming crusts on various substrates. The substrate can be rocks throughout the intertidal zone, or, as in the case of the Corallinales, reef-building coral reef, corals, and other living organisms including plants, such as mangroves and animals such as shelled molluscs. The coralline red algae are major members of coral reef communities, cementing the corals together with their crusts. Among the ...

Green Algae
The green algae (: green alga) are a group of chlorophyll-containing autotrophic eukaryotes consisting of the phylum Prasinodermophyta and its unnamed sister group that contains the Chlorophyta and Charophyta/ Streptophyta. The land plants ( Embryophytes) have emerged deep within the charophytes as a sister of the Zygnematophyceae. Since the realization that the Embryophytes emerged within the green algae, some authors are starting to include them. The completed clade that includes both green algae and embryophytes is monophyletic and is referred to as the clade Viridiplantae and as the kingdom Plantae. The green algae include unicellular and colonial flagellates, most with two flagella per cell, as well as various colonial, coccoid (spherical), and filamentous forms, and macroscopic, multicellular seaweeds. There are about 22,000 species of green algae, many of which live most of their lives as single cells, while other species form coenobia (colonies), long filaments ...
