Chaenotheca brachypoda is a species of lichen in the family Coniocybaceae. It was first described in 1816 by Erik Acharius as Coniocybe brachypoda. Leif Tibell transferred it to the genus Chaenotheca in 1987. [2]
Chaenotheca is a genus of lichenized fungi within the family Coniocybaceae. The sexual reproduction structures are a mass of loose ascospores that are enclosed by a cup shaped exciple sitting on top of a tiny stalk, having the appearance of a dressmaker's pin, hence the common name pin lichen. Genus members are also commonly called needle lichens. Photobiont partners for Chaenotheca include members of the algae genera Symbiochloris, Trebouxia, Trentepohlia, and Tritostichococcus.
Calicium is a genus of leprose lichens. It is in the family Caliciaceae, and has 40 species.
Polyblastia is a genus of lichenized fungi in the family Verrucariaceae. As of 2020, it consists of about 40 species combined with about 50 orphaned species. The main difference with the genus Verrucaria is related to spores, which are muriform in Polyblastia.
Microcalicium is a genus of lichen-forming fungi in the order Pertusariales. It is the only genus in the monotypic family Microcaliciaceae. These taxa were circumscribed by the Finnish lichenologist Edvard August Vainio in 1927, with Microcalicium disseminatum assigned as the type species.
Tylophoron is a genus of lichen-forming fungi in the family Arthoniaceae. The genus was circumscribed in 1862 by the Finnish lichenologist William Nylander.
Chaenothecopsis is a genus of about 40 species of pin lichens in the family Mycocaliciaceae.
Phaeocalicium is a genus of fungi in the family Mycocaliciaceae. The genus was circumscribed in 1970 by German lichenologist Alexander Schmidt, with Phaeocalicium praecedens assigned as the type species.
Stenocybe is a genus of fungi in the family Mycocaliciaceae. It has 14 species.

Ficus brachypoda is a tree in the family Moraceae native to northern Australia. It is a banyan of the genus Ficus which contains around 750 species worldwide in warm climates, including the edible fig.
Lichens are symbiotic organisms made up of multiple species: a fungus, one or more photobionts and sometimes a yeast. They are regularly grouped by their external appearance – a characteristic known as their growth form. This form, which is based on the appearance of vegetative part of the lichen, varies depending on the species and the environmental conditions it faces. Those who study lichens (lichenologists) have described a dozen of these forms: areolate, byssoid, calicioid, cladoniform, crustose, filamentous, foliose, fruticose, gelatinous, leprose, placoidioid and squamulose. Traditionally, crustose (flat), foliose (leafy) and fruticose (shrubby) are considered to be the three main forms. In addition to these more formalised, traditional growth types, there are a handful of informal types named for their resemblance to the lichens of specific genera. These include alectorioid, catapyrenioid, cetrarioid, hypogymnioid, parmelioid and usneoid.
Circinaria is a genus of crustose lichens in the family Megasporaceae. It was circumscribed by Johann Heinrich Friedrich Link in 1809.
Rolf Santesson (1916–2013) was a Swedish lichenologist and university lecturer. He was awarded the Acharius Medal in 1992 for his lifetime contributions to lichenology.
Leif Tibell is a Swedish lichenologist and Emeritus Professor at the University of Uppsala. He is known for his expertise on calicioid lichens. He was awarded the Acharius Medal in 2012 for lifetime achievements in lichenology.
Chaenotheca chlorella is a species of lichen belonging to the family Coniocybaceae.
Chaenotheca cinerea is a species of pin lichen in the family Coniocybaceae. It was first described in 1800 by Christiaan Hendrik Persoon as Calicium cinereum. Leif Tibell transferred it to the genus Chaenotheca in 1987.
Atla is a genus of crustose lichens in the family Verrucariaceae. It has nine species that grow on rocks or on soil.
Chaenothecopsis kilimanjaroensis is a species of lichenicolous (lichen-dwelling) pin lichen in the family Mycocaliciaceae. Found in the cloud forests of Tanzania, it was described as a new species in 2019. These tiny lichens have a short stalk, which can be either single or formed in aggregates on the same thallus. The stalks are medium brown at the base and become translucent in water. This species has unique spores, which contain a single septum, are arranged in a single row in the ascus, and have a surface ornamented with elongated, blister-like structures.
Xylopsora canopeorum is a squamulose (scaly), corticolous (bark-dwelling) lichen species in the family Umbilicariaceae. Discovered in the canopies of Sequoia sempervirens in California, United States, it was formally described as new to science in 2018. It is endemic to the central coastal region of California, living within the unique ecosystems of Big Basin Redwoods State Park and Armstrong Redwoods State Natural Reserve, areas known for their ancient coast redwood forests. The lichen evolves from a crust-like to scale-like form, developing into coral-like crusts as it matures, complemented by distinctive flat, black reproductive discs. This species has varying greyish-green to medium brown coloration and occasionally forms soralia, which release powdery reproductive propagules called soredia. Xylopsora canopeorum is distinguished from closely related species by its smaller, partly coral-like squamules (scales), the occurrence of soralia on its surface, and in some specimens, the presence of both thamnolic and friesiic acids within the thallus.
Chaenotheca papuensis is a species of crustose lichen in the family Coniocybaceae. Found in Papua New Guinea, it was formally described as a new species in 2003 by the lichenologists André Aptroot and Leif Tibell. The type specimen was collected by Aptroot in 1995 from the Owen Stanley Range, at an elevation of about 2,100 m (6,900 ft); there, in the remote mountain village Myola, it was found growing on the bark of huts and on wood.
