Pannaria minutiphylla is a species of lichen in the family Pannariaceae, [1] described as a new species in 2013 by Arve Elvebakk. The species is similar to Pannaria phyllidiata , but can be distinguished by its smaller phyllidia and ascospores that are elongated to ellipsoid.

Taxonomy

Pannaria minutiphylla was formally described by Arve Elvebakk in 2013. The specific epithet minutiphylla refers to the species' numerous small phyllidia . [2] [2]

Description

The lichen has a foliose (leafy) thallus, that is either corticolous (bark-dwelling), foliicolous (leaf-dwelling), or occasionally saxicolous (rock-dwelling). It forms rosettes of 3–15 cm (1+3165+78 in) in diameter. The lobes are irregularly to somewhat dichotomously branched. These lobes are discrete in peripheral parts of the thallus, and imbricate towards the centre. The upper surface of the thallus is pale greyish-green when fresh and dry, turning salad-green when moist, and gradually turning chestnut brown after storage. The upper cortex is 25–40  μm thick. Phyllidia are common along the margins, and the photobiont layer is composed of more or less spherical cells. The medulla is mostly white, with a dark brown lower part. [2]

Apothecia are absent, sparse, or common, with a rufous-brown disc . The hymenium is colourless and intensely IKI+ blue. Proper ascospores are hyaline, non-septate, and regularly elongate to ellipsoid. [2]

Chemistry

The species tests negative for UV, C, K, KC, and Pd spot test reactions. Thin-layer chromatography reveals the presence of vicanicin as a major compound, along with 3–4 unidentified terpenoids. High-performance liquid chromatography also indicates vicanicin as a major compound, with occasional trace amounts of norvicanicin. [2]

Distribution and habitat

Pannaria minutiphylla is common in Victoria and Tasmania, Australia. In New Zealand, it is widespread throughout both the North and South Islands, and also found in the Auckland Islands and Campbell Island. The species grows on trunks of various phorophytes and occasionally on rocks or leaves. [2]

Pannaria is a genus of lichen-forming fungi in the family Pannariaceae. The widespread genus contains an estimated 51 species, found primarily in tropical regions.

Pannaria phyllidiata is a species of lichen in the family Pannariaceae. Known from Australia, it was described as new to science in 2011. It is characterised by its unique phyllidia and distinct distribution.

Gibbosporina is a genus of 13 species of foliose lichens in the family Pannariaceae. It contains species that molecular phylogenetic analysis clustered together in a clade previously referred to as the "Physma"-group. Despite their morphological differences, this group shares several uniting characteristics. They have ring-like excipular margins around the thallus; strongly amyloid internal ascus structures; well-developed perispores that feature irregular gibbae, but not verrucae ; lacks secondary compounds than can be detected by thin-layer chromatography; and have tropical distributions.

Scytinium is a genus of lichen-forming fungi in the family Collemataceae. It has 49 species. These lichens are typically found on basic rocks, soil, and trees, occasionally in association with mosses. Despite the morphological and ecological diversity within Scytinium, its species share similar ascospore features, such as shape and septation, as well as a small to medium-sized thallus with at least a partial cortex.

<i>Lecidea tessellata</i> Species of lichen

Lecidea tessellata is a species of saxicolous (rock-dwelling), crustose lichen in the family Lecideaceae. It was formally described as a species in 1819 by German botanist Heinrich Flörke. In northern North America, it is common and widely distributed, growing on non-calcareous rocks. It also occurs in Afghanistan, China, Nepal, Europe, and Russian Asia. In India, it has been recorded only from the alpine Western Himalayas at an altitude of 3,450 m (11,320 ft). Its southern distribution extends to James Ross Island, where it is locally common.

Fuscopannaria rugosa is a species of corticolous (bark-dwelling), lichen in the family Pannariaceae. It is found in Hubei and Guanxi in China, where it grows in mountainous forests. Fuscopannaria rugosa is identifiable by its foliose-squamulose thallus, which has longitudinal wrinkles on the upper surface. It also has a distinct hypothallus, a relatively thick algal layer, and a cortex made up of thick-walled cells in both the thalline and apothecial structures. It produces simple, hyaline ascospores that have a smooth, pointed tip at their apex.

Astrothelium xanthosuperbum is a species of corticolous (bark-dwelling) lichen in the family Trypetheliaceae. It is found in Rondônia, Brazil. The species is characterized by its large muriform ascospores and is similar in appearance to Astrothelium disjunctum.

Fissurina amyloidea is a little-known species of script lichen in the family Graphidaceae. It is found in the primary rainforests of Rondônia, Brazil. It is characterized by its weakly carbonizedlirellae and thick-walled, strongly amyloid ascospores. Despite its superficial similarity to Fissurina subfurfuracea, F. amyloidea exhibits unique anatomical features that set it apart from other species within the genus.

Acanthotrema kalbii is a species of corticolous (bark-dwelling) lichen in the family Graphidaceae. First classified as a new species in 2012, the lichen is found in Costa Rica, where it grows in partially shaded areas of disturbed primary forest within the montane rainforest zone. This lichen stands out from its close relative, A. brasilianum, primarily due to the internal structure of its larger ascospores. The inaugural specimen of A. kalbii used for the species' formal description, was located on tree bark in a montane rainforest in the Las Tablas Protected Zone. The lichen is recognisable by its grey-green thallus, which varies from smooth to uneven and produces slender isidia, tiny outgrowths, up to 2 mm in length.

Catenarina desolata is a species of lichen in the family Teloschistaceae. It was formally described as a new species in 2014 by lichenologists Ulrik Søchting, Majbrit Søgaard, and Arve Elvebakk. It is predominantly found in the southernmost parts of Chile, with some instances in Antarctica and the Kerguelen Islands. Characterised by its dark reddish-brown to almost purple apothecia, this species of lichen was originally thought to be lichenicolous, meaning it grows on other lichens, particularly Aspicilia species. The later discovery non-lichen-dwelling examples from James Ross Island in the Antarctic Peninsula suggests that it is not exclusively lichenicolous. Its distinctive secondary compound, 7-chlorocatenarin, sets it apart from other lichens in the region.

Enterographa rotundata is a species of corticolous (bark-dwelling) crustose lichen in the family Roccellaceae. This species was discovered in Brazil, growing on the smooth bark of trees in the Brazilian Caatinga forest. It has round apothecia, a feature that sets it apart from most of its kind.

<i>Fissurina alligatorensis</i> Species of lichen

Fissurina alligatorensis is a species of corticolous (bark-dwelling) crustose lichen in the family Graphidaceae. Characteristics of the lichen include its lack of secondary compounds and an ecorticate thallus. Its habitat is centred around the Alligator River National Wildlife Refuge in North Carolina, USA, and it has a preference for soft-barked trees. While it can easily be confused with other Fissurina species, there are specific characters that distinguish it, such as its violet ascospores and its lirellate fruiting bodies.

Thalloloma rubromarginatum is a little-known species of corticolous (bark-dwelling) script lichen in the family Graphidaceae. This lichen stands out from its counterparts within its genus, most notably Thalloloma haemographum, due to its corticate thallus and the presence of norstictic acid. Thalloloma rubromarginatum is found in the Sierra palm forests of Puerto Rico.

Zeroviella esfahanensis is a species of saxicolous (rock-dwelling) foliose lichen in the family Teloschistaceae. It is found in various locations across the Palearctic realm, having been recorded in Europe, Asia, and North Africa, where it grows in alpine and cold desert areas.

Astrothelium miniannulare is a species of crustose lichen in the family Trypetheliaceae, characterized by its corticolous (bark-dwelling) habitat and presence of lichexanthone. Characteristics of the lichen include the whitish ring around its ostiole and the presence of three septa in the ascospores.
