Heiomasia
''Heiomasia'' is a genus of corticolous (bark-dwelling), crustose lichens in the family Graphidaceae. It has five species. Taxonomy The genus was circumscribed in 2010 by Matthew Nelsen, Robert Lücking and Eimy Rivas Plata, with '' Heiomasia sipmanii'' assigned as the type species. This species, found in Thailand and the Philippines, was first described as ''Herpothallon sipmanii''. Molecular phylogenetic analysis showed that it, along with another then-undescribed species, '' H. seaveyorum'', formed a clade with a distinct lineage in the Graphidaceae, and so ''Heiomasia'' was created to contain them. The genus name honours Harrie Sipman, "recognizing his substantial contributions to tropical lichenology". The name is constructed from letters of his full name: Henricus Johannes Maria Sipman (with the "J" changed to "I"). Description ''Heiomasia'' species have pale green to whitish thalli that are effuse (spread out) and byssoid (wispy, like cotton), and often have a white ...

Harrie Sipman
Henricus (Harrie) Johannes Maria Sipman (born 1945) 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. Life and career Sipman was born in 1945 in Sittard, Netherlands. He attended Utrecht University, where he studied botany. Sipman was appointed to the Herbarium and the Institute for Systematic Botany from 1972 to 1982, where his focus was on lichenology and bryology. During this time, some of his research publications dealt with taxa from the lichen genera ''Cladonia'' and ''Stereocaulon'', and on the Musci '' Anisothecium staphylinum'', ''Campylopus'' and ''Ephemerum''. His supervisor was Robbert Gradstein (nl). He earned his PhD in 1983 after defending a thesis on the family Megalosporaceae, later published as a monograph in the ''Bibliotheca L ...

Graphidaceae
The Graphidaceae are a family of lichens in the order Ostropales. Distribution and ecology The vast majority of Graphidaceae species are restricted to the tropics. Most Graphidaceae species are epiphytic (i.e. they grow only on plants). Genera A recent (2020) estimates places 31 genera and about 990 species in Graphidaceae. The following list indicates the genus name, the taxonomic authority, year of publication, and the number of species: *''Acanthothecis'' – 5 spp. *''Acanthotrema'' – 1 sp. *''Aggregatorygma'' – 1 sp. *''Allographa'' – 183 spp. *''Amazonotrema'' – 1 sp. *'' Ampliotrema'' – 1 sp. *'' Anomalographis'' – 2 spp. *''Anomomorpha'' – 8 spp. *''Astrochapsa'' – 29 spp. *'' Austrotrema'' – 3 spp. *'' Borinquenotrema'' – 1 sp. *'' Byssotrema'' – 1 sp. *''Carbacanthographis'' – 22 spp. *''Chapsa'' – 51 spp. *''Chroodiscus'' – 17 spp. *'' Clandestinotrema'' – 17 spp. *'' Compositrema'' – 4 spp. *'' Corticorygma'' – 1 ...

Arthoniales
The Arthoniales is the second largest order of mainly crustose lichens, but fruticose lichens are present as well. The order contains around 1500 species, while the largest order with lichenized fungi, the Lecanorales, contains more than 14000 species. Classification The Arthoniales is one of two orders of the class Arthoniomycetes within the phylum Ascomycota. The order includes seven families ( Andreiomycetacae, Arthoniaceae, Chrysotrichaceae, Lecanographaceae, Opegraphaceae, Roccellaceae and Roccellographaceae). Lecanographaceae, Roccellographaceae, Opegraphaceae and Roccellaceae are well-supported families within Arthoniales, and they were circumscribed in 2011. Andreiomycetaceae was described as a new family by Hodkinson and Lendemer in 2013. The Arthoniales is the sister group to Dothideomycetes. Figure 1.

Cryptothecia
''Cryptothecia'' is a genus of white to greenish crustose lichens that grow on bark, wood, or leaves. in tropical or subtropical areas worldwide. It has a conspicuous prothallus that develops around its periphery which can be bright red in some species, hence the common name wreath lichen. The main vegetative body (thallus) lacks a cortex (ecorticate and is often immersed in the substrate or byssoid (whispy, like teased wool). The medulla is white, well defined, and often peppered with calcium oxalate crystals. Ascomata are not well defined, being cushions of soft white mycelium immersed in the medullary tissue, hence the name from the Greek ''krypto'' = "to conceal" and ''theke'' = "a container or sheath". There are about 45 described species in the genus according to one source, and 75 species according to another. The genus is in the family Arthoniaceae. It contains '' Trentepohlia'', a green alga, as its photobiont partner. Two species have been described in North America.Br ...

Herpothallon
''Herpothallon'' is a genus of crustose lichens in the family Arthoniaceae. It has about 50 species. Taxonomy The genus was circumscribed in 1930 by German lichenologist Friedrich Tobler, with ''Herpothallon sanguineum'' assigned as the type species. Tobler erroneously believed that the fungus was a member of the Basidiomycota. After it was recognized as an ascolichen, it was referred to either ''Chiodecton'' (family Roccellaceae) or ''Cryptothecia'' (family Arthoniaceae). In 2009, ''Herpothallon'' was resurrected following a publication by André Aptroot, Göran Thor, Robert Lücking, and John Elix, in which they recognized 29 species worldwide. The type species is now known as ''Herpothallon rubrocinctum'', or in the vernacular as the "Christmas lichen". Description ''Herpothallon'' is characterized by the byssoid (a wispy or cottony texture) prothallus (i.e., the first purely fungal layer upon which an algae-containing thallus develops) and hypothallus (i.e., a growth of u ...

Robert Lücking
Robert Lücking (born 1964) is a German lichenologist. He is a leading expert on foliicolous lichens–lichens that live on leaves. Life and career Born in Ulm in 1964, Lücking earned both his master's (1990) and PhD degree (1994) at the University of Ulm. Both degrees concerned the taxonomy, ecology, and biodiversity of foliicolous lichens. His graduate supervisor was mycologist and bryologist Sieghard Winkler, who had previously studied epiphyllous (upper leaf-dwelling) fungi in El Salvador and Colombia. In 1996 Lücking was awarded the Mason E. Hale award for an "outstanding doctoral thesis presented by a candidate on a lichenological theme". His thesis was titled ''Foliikole Flechten und ihre Mikrohabitatpraferenzen in einem tropischen Regenwald in Costa Rica'' ("Foliicolous lichens and their microhabitat preferences in a tropical rainforest in Costa Rica"). In this work, Lücking recorded 177 foliicolous lichen species from the shrub layer in a Costa Rican tropical forest. L ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
