Bryoria is a genus of lichenized fungi in the family Parmeliaceae. Many members of this genus are known as horsehair lichens. [2] The genus has a widespread distribution, especially in boreal and cool temperate areas.

Taxonomy

Bryoria was circumscribed in 1977 by lichenologists Irwin Brodo and David Hawksworth, with Bryoria trichodes as the type species. [3]

Molecular studies by Velmala et al. (2014) [4] and Boluda et al. (2019) [5] showed that several North American Bryoria taxa, including B. pikei (formerly identified as North American "B. capillaris"), B. pseudofuscescens , B. friabilis, and B. inactiva, belong to a single genetic clade with minimal genetic variation. While these taxa were originally distinguished by their secondary metabolites, ecology, and geographic distributions, DNA analysis did not support maintaining them as separate species. However, Bruce McCune and Daphne Stone (2022) noted that these chemical variants have distinct ecological preferences – for instance, B. friabilis is associated with inland wet forests and is common at low elevations in western Oregon and Washington, while B. pseudofuscescens dominates at higher elevations in the Cascades. To preserve this valuable ecological information while reflecting genetic reality, these taxa were reclassified as varieties of B. pseudofuscescens, distinguished by their chemical composition: var. pseudofuscescens (norstictic acid), var. friabilis (gyrophoric acid), var. inactiva (acid-deficient), and var. pikei (alectorialic acid). [6]

Description

Bryoria species are fruticose, slender and hair-like, tending to grow hanging (pendent) or like a small bush. They range in colour from dark brown to pale greyish brown to grey in some species. Ascospores are colourless, ellipsoid, numbering eight per ascus. [7]

Other hair-like lichens that may be confused with Bryoria include dark brown species of Bryocaulon , Nodobryoria , Pseudephebe , Alectoria , or Cetraria . [7]

Habitat and distribution

Found almost exclusively on conifers, or on tundra soil, [7] Bryoria collectively has a widespread distribution, especially in boreal and cool temperate areas. [8]

Ecology

Studies have shown that species in the genus Bryoria, characterized by their dark melanic pigments, show distinct ecological preferences compared to pale yellow-green usnic acid-containing hair lichens. Research on coniferous forests in British Columbia demonstrated that Bryoria species strongly favor sun-exposed, well-ventilated locations, particularly dominating south-facing slopes and upper canopy positions. This distribution pattern reflects an evolutionary specialization where melanic pigments provide crucial protection against high light exposure, allowing these lichens to thrive in dry, sun-exposed environments while shielding their photobionts from radiation damage. The melanin in their cortex effectively absorbs most incident solar radiation, enabling Bryoria species to tolerate temperatures up to 70 °C (158 °F) when desiccated. This adaptation contrasts with usnic acid-containing hair lichens, which typically prefer more shaded and humid conditions. The strong correlation between Bryoria abundance and canopy openness suggests that these lichens are particularly well-adapted to early-successional forest conditions where light exposure is high. [9]

<span class="mw-page-title-main">Parmeliaceae</span> Family of lichens

The Parmeliaceae is a large and diverse family of Lecanoromycetes. With over 2700 species in 71 genera, it is the largest family of lichen-forming fungi. The most speciose genera in the family are the well-known groups: Xanthoparmelia, Usnea, Parmotrema, and Hypotrachyna.

<i>Pseudephebe</i> Genus of fungi

Pseudephebe is a genus of fruticose lichens in the family Parmeliaceae. It contains three species that grow on rocks.

<i>Hypogymnia</i> Genus of lichens

Hypogymnia is a genus of foliose lichens in the family Parmeliaceae. They are commonly known as tube lichens, bone lichens, or pillow lichens. Most species lack rhizines that are otherwise common in members of the Parmeliaceae, and have swollen lobes that are usually hollow. Other common characteristics are relatively small spores and the presence of physodic acid and related lichen products. The lichens usually grow on the bark and wood of coniferous trees.

<i>Melanohalea</i> Genus of lichen

Melanohalea is a genus of foliose lichens in the family Parmeliaceae. It contains 30 mostly Northern Hemisphere species that grow on bark or on wood. The genus is characterised by the presence of pseudocyphellae, usually on warts or on the tips of isidia, a non-pored epicortex and a medulla containing depsidones or lacking secondary metabolites. Melanohalea was circumscribed in 2004 as a segregate of the morphologically similar genus Melanelia, which was created in 1978 for certain brown Parmelia species. The methods used to estimate the evolutionary history of Melanohalea suggest that its diversification primarily occurred during the Miocene and Pliocene epochs.

<i>Melanelixia</i> Genus of fungi

Melanelixia is a genus of foliose lichens in the family Parmeliaceae. It contains 15 Northern Hemisphere species that grow on bark or on wood. The genus is characterized by a pored or fenestrate epicortex, and the production of lecanoric acid as the primary chemical constituent of the medulla. Melanelixia was circumscribed in 2004 as a segregate of the related genus Melanelia.

<i>Nodobryoria</i> Genus of lichens

Nodobryoria is a genus of medium to large, reddish-brown lichens that are hair-like to shrubby in shape and grow on conifer trees. The genus contains three species, distributed in North America and Greenland, which were previously included in the genus Bryoria. Nodobryoria is similar in appearance to Bryoria, but is differentiated because it does not contain the polysaccharide lichenin, and it has a unique cortex composed of interlocking cells that look like pieces of a jigsaw puzzle when viewed under a light microscope.

<i>Gowardia</i> Genus of fungi

Gowardia is a genus of medium-sized, greyish hair lichens in the family Parmeliaceae. It is a circumpolar genus, mainly restricted to arctic-alpine habitats in northern Canada, Europe, and Russia.

Bryoria hengduanensis is a species of lichen of the genus Bryoria. It was described as new to science in 2003 by lichenologists Li-Song Wang and Hiroshi Harada. It is found in the Hengduan Mountains of southern China, where it grows on twigs and branches in coniferous forests at elevations of 3,000–4,000 metres (9,800–13,100 ft). The Hengduan Mountains is a region of high Bryoria biodiversity, as 24 species are known from this area.

Teuvo ("Ted") Tapio Ahti is a Finnish botanist and lichenologist who has made significant contributions to the taxonomy and biogeography of lichens.

His research output spans more than seven decades, comprising over 450 scientific publications across lichenology, mycology, and botanical science.

<i>Pseudephebe pubescens</i> Species of lichen

Pseudephebe pubescens, also known as 'fine rock wool', is a temperate alpine lichen. It is a member of the genus Pseudephebe, a lichen group characterized by dense mats of brown to near-black "hairs".

Melanohalea zopheroa is a species of lichen in the family Parmeliaceae. It was first formally described in 1977 by Ted Esslinger as Parmelia zopheroa. A year later, he transferred it to the new genus Melanelia, which he created to contain the brown Parmeliae species. In 2004, after early molecular phylogenetic evidence showed that Melanelia was not monophyletic, Melanohalea was circumscribed by lichenologists Oscar Blanco, Ana Crespo, Pradeep K. Divakar, Esslinger, David L. Hawksworth and H. Thorsten Lumbsch, and M. zopheroa was transferred to it. The lichen has a disjunct distribution, as it is found in South America (Chile) and in New Zealand.

<i>Melanohalea elegantula</i> Species of lichen in the family Parmeliaceae

Melanohalea elegantula, commonly known as the elegant camouflage lichen, is a species of lichen in the family Parmeliaceae. It was first described by Alexander Zahlbruckner in 1894 as Parmelia aspidota var. elegantula. Hungarian lichenologist Ödön Szatala promoted it to full species status, as Parmelia elegantula, in 1930. Ted Esslinger transferred it to the genus Melanelia in 1978. Finally, it was assigned to the newly circumscribed genus Melanohalea in 2004.

Sulcaria spiralifera is a species of fruticose lichen in the family Parmeliaceae. First described in 1977 as a species of Bryoria, it was transferred to the genus Sulcaria in 2014 based on DNA analysis. The species comprises two chemical variants now recognized as varieties: the typical variety and var. pseudocapillaris, which differ in their chemical composition and spot test reactions. It is found in the northwestern United States, where it grows as an epiphyte, hanging from a variety of tree species in open or shaded maritime forests. The lichen is characterized by its pendulous brown thallus with spiral-arranged white pores (pseudocyphellae) on its surface, extending 4–12 cm in length.
