Taxonomy

The lichen was formally described in 2018 by Manuela Dal-Forno, Bibiana Moncada, and Robert Lücking. It has previously been included in the broadly defined concept of Sticta damicornis , but various molecular phylogenetic studies showed that there were multiple distinct cryptic species included under this name. [1] S. aongstroemii was actually first described by Johannes Müller Argoviensis in 1881 as S. laciniata var. trichophora, based on collections made from Minas Gerais and Rio de Janeiro. [2] However, the varietal epithet trichophora has been used as the species epithet for an unrelated species of Sticta by Edvard August Vainio in 1913, so Müller's usage is "blocked", and thus the replacement name, Sticta aongstroemii was proposed. The new epithet honours Swedish bryologist Johan Ångström, who collected the type specimen. [1]

Description

Sticta aongstroemii is distinguished from other green algal-partnering Sticta species because of its unique characteristics. These include lobes with parallel edges that are laciniate (edges of the lobes having many fine, finger-like projections) and have tips that range from rounded to tapering. Additionally, it has densely packed marginal apothecia that are contrasting with the noticeable, whitish cyphellae . Moreover, Sticta aongstroemii has a branching pattern that is anisotomous (a branching pattern where the lobes grow at different angles) and the lobes are growing at an angle of approximately 45–60°. Furthermore, it has a thin but distinct, dark brown lower tomentum . [1]

<i>Sticta</i> Genus of lichens

Sticta is a genus of lichens in the family Peltigeraceae. The genus has a widespread distribution, especially in tropical areas, and includes about 114 species. These lichens have a leafy appearance, and are colored brown or black. Sticta species with cyanobacteria as photobionts can fix nitrogen from the atmosphere, and due to their relative abundance and high turnover, they contribute appreciably to the rainforest ecosystem. They are commonly called spotted felt lichens.

Cora hirsuta is a species of basidiolichen in the family Hygrophoraceae. Found in the páramo region near Bogotá at over 3,000 m (9,800 ft) elevation, it was described as new to science in 2011. The lichen, characterised by its distinctively hairy upper surface and smaller lobes, thrives in a variety of habitats, including soil, bryophytes, and as epiphytes on trees.

The specific epithet hafecesweorthensis refers to Hafecesweorthe, an early Anglo-Saxon name for Hawksworth in Yorkshire, and an indirect tribute to mycologist David Leslie Hawksworth. The lichen is only known from its type locality in the Bosques Peña de Santa Bárbara Natural Reserve in Cundinamarca. Here it occurs in wet subpáramo and subandine cloud forest at altitudes between 2,500 and 3,000 m. The lichen grows on the ground, between other lichens and bryophytes.

Found in Costa Rica, it was formally described as a new species in 2016 by Manuela Dal Forno, José Luis Chaves, and Robert Lücking. The specific epithet paraminor refers to its close relationship with Cora minor. Cora paraminor is known to occur only at the type locality at the Los Santos Forest Reserve in Cerro de la Muerte. Here it grows in mountainous forest as an epiphyte, on the twigs and branches of trees. Its phylogenetically distinct namesake, C. minor, is also found in Costa Rica, but in Chirripó National Park. The authors suggest this may represent an example of allopatric speciation resulting from geographic isolation of these two species caused by the two isolated, highest-altitude Costa Rican mountain peaks.

Similar species include Cora canari, C. hafecesweorthensis, and C. imi.

Cora cyphellifera is a species of basidiolichen in the family Hygrophoraceae. Found in northern Ecuador, it was formally described as a new species in 2013 by Manuela Dal-Forno, Frank Bungartz, and Robert Lücking. The type specimen was collected near the entrance to the Alto Choco Reserve at an elevation of 2,053 m (6,736 ft). Here, in open, disturbed forest patches, the lichen grows as an epiphyte on tree branches and twigs, forming foliose, light bluish-green thalli up to 15 cm (6 in) across, and comprising 20 to 30 semicircular lobes in each thallus. Cora cyphellifera is only known to occur at the type locality, which is a montane rainforest. The specific epithet refers to the unusual cyphelloid structure of the thallus; this characteristic is otherwise unknown in the genus Cora. According to the authors, "it almost looks like the lichenized thallus is parasitized by a non-lichenized, cyphelloid mushroom".

Yoshimuriella peltigera is a species of corticolous (bark-dwelling), foliose lichen in the family Peltigeraceae. It occurs in neotropical mountainous rainforests.
