Biology:Pannaria

From HandWiki

Pannaria is a genus of lichen-forming fungi in the family Pannariaceae.[1] These lichens form leaf-like, scaly, or crusty patches that typically arrange themselves in loose rosettes on tree bark in humid forests. Most species partner with nitrogen-fixing cyanobacteria, though some contain green algae instead. The genus was established in 1828 and now includes about 80 recognized species found worldwide, particularly in tropical and subtropical regions.

Description

Pannaria forms a thallus that can be leaf-like (foliose), a mosaic of tiny scales (squamulose), or a thin crust (crustose). Many species arrange their lobes in loose rosettes and, unlike several related genera, they rarely develop the blue-black felt ([[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]) seen beneath other cyanobacterial lichens. The upper surface ranges from grey-blue to deep brown-black and may carry a light dusting of frost-like crystals ([[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]). Most species partner with the filamentous cyanobacterium Nostoc, but members of the Pannaria sphinctrina group instead contain green algal cells.[2]

The lichen's sexual fruiting bodies are sessile apothecia whose red-brown to black [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] are framed by a persistent rim of thallus tissue. That rim has two zones: an outer layer of tightly packed, brick-like cells and an inner layer that is looser and packed with [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] cells. A thin, pale [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] of [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] cells surrounds the hymenium. The asci hold eight ascospores, show no blue reaction to potassium–iodide stain (K/I–) and lack the amyloid plug found in many related taxa. Their spores are colourless, single-celled, ellipsoidal and often end in one or two small points; the outer wall is finely warted or ridged.[2]

Asexual reproduction is limited to scattered pycnidia that release straight, rod-shaped conidia. Thin-layer chromatography usually detects no secondary metabolites, though some species contain pannarin, which produces an orange-red colour with the para-phenylenediamine (Pd) spot test.[2]

Photobiont

Like most members of the Pannariaceae, species of Pannaria partner with filamentous, nitrogen-fixing cyanobacteria belonging to the genus Nostoc. A multilocus survey of 37 thalli representing 21 species showed that these [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] are drawn from two broad Nostoc lineages previously known as the "Nephroma guild" and the "Peltigera guild"; the Pannaria sequences are scattered across both, with a gradual transition between them.[3]

Host choice is flexible. [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] (cyanobacteria-only) and [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] (cyanobacteria plus green-algal) species do not segregate cleanly by [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]]: some tripartite southern-hemisphere taxa share identical Nostoc strains with corticolous (bark-dwelling) bipartite species from both hemispheres, whereas other Pannaria species show marked selectivity, keeping to a narrow subset of strains. This breadth of associations contrasts with the tighter photobiont fidelity reported for genera such as Nephroma and Peltigera.[3]

Ecology

Species of Pannaria grow mainly as epiphytes on the bark of trees in sheltered, humid forests. They are encountered far less often on shaded rocks or on thin, moss-covered soil, where the micro-climate is similarly cool and moist.[2]
