Lecanoraceae
The Lecanoraceae are a family of lichen A lichen ( , ) is a hybrid colony (biology), colony of algae or cyanobacteria living symbiotically among hypha, filaments of multiple fungus species, along with yeasts and bacteria embedded in the cortex or "skin", in a mutualism (biology), m ...ized fungi in the order Lecanorales. Species of this family have a widespread distribution. Taxonomy Lecanoraceae was circumscribed by German lichenologist Gustav Wilhelm Körber in 1855.

Lecidella
''Lecidella'' is a genus of crustose lichens in the family Lecanoraceae. Taxonomy ''Lecidella'' was circumscription (taxonomy), circumscribed by German lichenologist Gustav Wilhelm Körber in 1855. It was not widely used until more than a century later, when Hannes Hertel recognized it first as a subgenus of ''Lecidea'', and then a couple of year after as a distinct genus. A phylogenetic analysis of the genus using 11 species (mostly from China) found that ''Lecidella'' species fall into three major clades, which were proposed as three informal groups: ''Lecidella stigmatea'' group, ''L. elaeochroma'' group and'' L. enteroleucella'' group. Description ''Lecidella'' species have a thallus that is crustose lichen, crustose, and , meaning that it resembles the genus ''Biatora''–having a proper exciple, which is not coal-black (, but coloured or blackening. It has eight-spored ascus, asci of the ''Lecidella'' type. The ascospores are and hyaline, while the conidia are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bryonora
''Bryonora'' is a genus of lichen-forming fungi in the family Lecanoraceae. These lichens typically grow on soil, mosses, plant debris, or rocks in arctic or alpine environments. The genus was circumscribed in 1983 by lichenologist Josef Poelt, with '' Bryonora castanea'' assigned as the type species. Taxonomy Phylogenetic studies have confirmed ''Bryonora''s placement within the Lecanoraceae. The genus ''Bryodina'', previously considered separate, is now treated as a synonym of ''Bryonora'' based on molecular evidence. As of 2022, the genus comprises 15 accepted species. Recent taxonomic changes include the description of a new species, '' Bryonora microlepis'', and the transfer of ''Lecanora castaneoides'' to ''Bryonora'' as ''B. castaneoides''. Description ''Bryonora'' species exhibit various thallus types, including crustose (forming a crust-like layer), (composed of small, scale-like structures), and (somewhat shrub-like). The reproductive structures, called apot ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Palicella
''Palicella'' is a genus of crustose lichens in the family Lecanoraceae. It contains six species. Taxonomy The genus was circumscribed in 2014 by lichenologists Pamela Rodriguez-De Flakus and Christian Printzen to accommodate the type species, '' Palicella glaucopa'' (formerly placed in the genus ''Lecidea''), and two closely related species, ''P. filamentosa'' and ''P. schizochromatica''. Molecular analyses of these lichens revealed a monophyletic clade that is sister to representatives from two Lecanoraceae genera, '' Lecanora symmicta'' and '' Pyrrhospora quernea''. Two additional species were transferred to ''Palicella'' from ''Lecanora'' in 2019. Description ''Palicella'' species have biatorine apothecia, which are often darkened (by the pigment known as ), an (a saucer-shaped rim around the hymenium) consisting of radiating, narrow hyphae with elongated lumina, and a hymenium with branched and sparsely anastomosed paraphyses. Other microscopic characteristics inc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Myriolecis
''Myriolecis'' is a genus of lichen in the family Lecanoraceae. It was originally circumscribed in 1909 by Frederic E. Clements with '' Myriolecis sambuci'' as the type species. The genus was later reinstated to accommodate the ''Lecanora disperse'' group and ''Arctopeltis''. Molecular phylogenetic data showed that this group of species formed a clade that is genetically distinct from ''Lecanora ''Lecanora'' is a genus of lichen commonly called rim lichens.Field Guide to California Lichens, Stephen Sharnoff, Yale University Press, 2014, Lichens in the genus '' Squamarina'' are also called rim lichens.

Adelolecia
''Adelolecia'' is a genus of crustose lichens in the family Lecanoraceae. These rock-dwelling lichens form thin crusts made up of small angular patches, typically reaching about 12 cm across with distinctive black, round fruiting bodies that sit directly on the surface. The genus includes four species found in mountainous and arctic regions, where they grow on various types of rock and are distinguished by chemical compounds (lichen products) that produce colourful diagnostic reactions when tested with laboratory solutions. Taxonomy The genus was circumscribed by Hannes Hertel and Josef Hafellner in 1984. The genus was formerly classified in the family Ramalinaceae, but molecular phylogenetic analysis showed it to belong to the Lecanoraceae. Description ''Adelolecia'' forms a thin crust on rock, either lying on the surface in tiny, angular islands () or growing within the upper grain of the stone itself. Colonies can reach about 12 cm across but lack a darker frin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Glaucomaria
''Glaucomaria'' is a genus of lichen-forming fungi in the family Lecanoraceae. It has seven species. The genus was circumscribed by Maurice Choisy in 1929. It contains crustose lichens formerly placed in the ''Lecanora rupicola'' species complex as defined by several previous authors. Description ''Glaucomaria'' is characterised by a crust-like (crustose) thallus, which is sometimes spread out with a radiating pattern (). The colour of the thallus ranges from white-yellowish green to pale grey. The apothecia (fruiting bodies) initially grow attached () and can become slightly raised () or nearly stalked (substipitate). These apothecia feature a heavily powdery () that reacts to the C spot test to produce an intense lemon-yellow colour. The margin of the apothecia is persistent, sometimes being pushed aside (finally excluded), and occasionally surrounded by a black, wavy () ring. The outer layer of the apothecia () typically has a cortex (containing hyphal fragments and dead, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pulvinora
''Pulvinora'' is a small genus of saxicolous (rock-dwelling), crustose lichens in the family Lecanoraceae. It has two species. The genus was circumscribed in 2021 by Evgeny Davydov and Lidia Yakovchenko to contain two species formerly in the '' Lecanora pringlei'' species group. The type species of the genus, '' P. stereothallina'', occurs in the Altai Mountains (Russia), while '' P. pringlei'' is found in North America. Description ''Pulvinora'' species have asci similar to those found in genus ''Lecanora''. Their apothecia are ''mycolecanorine'', meaning they are lecanorine (and so have a thalline margin with an intact cortex), but without photobiont cells in the thalline exciple. The apothecia eventually become convex with an algal layer that is pushed below the hypothecium. The form of the thallus is pulvinate (resembling tiny cushions), with squamules (scales) at the tips of pale brownish, branched structures similar to pseudopodetia A podetium (plural: podetia) ...

Josef Hafellner
Josef Hafellner (1951– ) is an Austrian mycologist and lichenologist. He was awarded the Acharius Medal in 2016 for his lifetime contributions to lichenology. Before his retirement, he was a professor at the Karl-Franzens-Universität in Graz. Hafellner started developing an interest in lichens while he was a student at this institution, studying under Josef Poelt. He earned a master's degree in 1975 and a PhD in 1978, defending a doctoral thesis about the genus '' Karschia''. In 2003, Hafellner received his habilitation. By this time, he had studied with French lichenologist André Bellemère (1927–2014) at Saint-Cloud, where he learned techniques of transmission electron microscopy and how their application in studying asci could be used in lichen systematics. His 1984 work ''Studien in Richtung einer natürlicheren Gliederung der Sammelfamilien Lecanoraceae und Lecideaceae'' has been described as "probably the single most influential publication in lichen systematics in ...

Bryodina
''Bryodina'' is a genus of two species of crustose lichens in the family Lecanoraceae. It was circumscribed by Austrian lichenologist Josef Hafellner in 2001 as a segregate of the large genus ''Lecanora''. It is distinguished from the morphologically similar genus ''Bryonora'' by the clearly separated hypothecium and excipulum, and by the thin-walled ascospore In fungi, an ascospore is the sexual spore formed inside an ascus—the sac-like cell that defines the division Ascomycota, the largest and most diverse Division (botany), division of fungi.

Japewia
''Japewia'' is a genus of lichen-forming fungi in the family Lecanoraceae. The genus was circumscribed in 1990 by the Norwegian lichenologist Tor Tønsberg, who assigned '' J. tornoënsis'' as the type species. The new genus is named in honour of Peter Wilfred James, a notable lichenologist, with ''Japewia'' being derived from the first letters of his initials (Ja) and his surname (Pe) followed by a typical Latin suffix (-wia). Description ''Japewia'' species incorporate green algae from the order Chlorococcales into their structure. The main body of the lichen, the thallus, is crust-like and firmly attached to the surface it grows on. The apothecia (fruiting bodies) are typically attached to the thallus and can either have a distinct margin or lack one. These apothecia are (simple and cup-shaped) and chestnut-coloured. The paraphyses (sterile filamentous cells in the apothecia) and the (the outer layer surrounding the apothecia) have hyphae (fungal filaments) that are ...
