Placomaronea lambii is a species of saxicolous (rock-dwelling) lichen in the family Candelariaceae. It occurs at high altitudes in Argentina, Ecuador, and Peru, where it grows on acidic rocks in open habitats.[1]
Taxonomy
The lichen was first scientifically described as a new species in 1965 by Finnish lichenologist Rainar Hakulinen, who placed it in the genus Candelariella.[2] Rolf Santesson transferred it to Placomaronea in 1974.[3] The species epithet lambi honours polar explorer and lichenologist Elke Mackenzie (formerly Lamb),[4] who collected the type specimen from the Tafí del Valle (Tucumán Province, Argentina, in 1947. There, in an alpine pasture at an altitude of 3,100 m (10,200 ft), it was found growing on a block of schistose rock.[1]
Description
Placomaronea lambii has a distinct rosette-like form, comprising numerous brownish-yellow [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] that can be multi-lobed and overlapping. The thallus has a dull brownish-yellow hue, while its reproductive structures, or apothecia, stand out with a darker yellow [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] and the pycnidia (asexual spores) appear as darker yellow to slightly brownish depressions or bumps. Its [[Glossary of lichen terms#{{biology:{1}}}|{{Biology:{1}}}]] are narrowly ellipsoid to nearly oblong, and typically measure 9.0–12.0 long by 3.0–4.5 µm wide.[1]
