Cinnabar is the more stable form, and is a structure akin to that of HgO: each Hg center has two short Hg−S bonds (each 2.36 Å), and four longer Hg···S contacts (with 3.10, 3.10, 3.30 and 3.30 Å separations). In addition, HgS is found in a black, non-cinnabar polymorph (metacinnabar) that has the zincblende structure. [5]
Cinnabar moth (Tyria jacobaeae) caterpillar feeding on a Senecio. The seed of common groundsel is a good green food for canaries and finches and it is available all year round. [9] Senecio vulgaris seed has been found in the droppings of sparrows, and seedlings have been raised from the excreta of various birds. Seed has also been found in cow ...
The moth is named after the red mineral cinnabar because of the red patches on its predominantly black wings. The species was first described by Carl Linnaeus in his 1758 10th edition of Systema Naturae. Cinnabar moths are about 20 mm (0.79 in) long and have a wingspan of 32–42 mm (1.3–1.7 in).
The appearance of the fruit bodies has been compared to amphibian eggs [34] or "small red tomato[es] surrounded by jelly". [35] They consist of a bright red, globose head atop a net-like stipe, covered in a thick gelatinous layer. [23] These fruit bodies are initially hypogeous, [22] but emerge from the ground as the stipe continues to expand. [34]
The seeds are 4–5 mm (0.16–0.20 in) in diameter and weigh on average 68 mg. [5] The berries exude a deep red resin, known as dragon's blood. [6] Like other monocotyledons, such as palms, the dragon's blood tree grows from the tip of the stem, with the long, stiff leaves borne in dense rosettes at the end. It branches at maturity to produce ...
Groundcover of Vinca major. Groundcover or ground cover is any plant that grows low over an area of ground, which protects the topsoil from erosion and drought.In a terrestrial ecosystem, the ground cover forms the layer of vegetation below the shrub layer known as the herbaceous layer, and provides habitats and concealments for (especially fossorial) terrestrial fauna.
Cystodermella cinnabarina is found fruiting in coniferous and deciduous forests, [11] on ground among moss, grass and litter. Being a saprotrophic fungus, it decays dead organic matter. It has been recorded under pine (Pinus nigra, Pinus pinea), oak, spruce (Picea orientalis), fir (Abies cephalonica) and chestnut (Castanea sativa) in Greece and ...
It is a type of plant known as a clubmoss, which is within one of the three main divisions of living vascular plants. It was formerly included in the superspecies Diphasiastrum complanatum. For many years, this species was known as Lycopodium flabelliforme or Lycopodium digitatum. [2] [3]
