Ceratocystis coerulescens is an ascomycete fungus and the causal agent of sapstreak disease in sugar maple trees. There is debate about whether it is one species or two; the second being Ceratocystis virescens. For simplicity, this page will refer to this pathogen as one species. It is also known by its anamorph name Endoconidiophora virescens.Host and SymptomsThis fungus is often found as a saprophyte on logs of woody species. It causes sapstreak disease in just one host species: Acer saccharum, commonly known as the sugar maple or rock maple. Symptoms include a sparse crown, dieback, dwarfed leaves, and cankers. Infected trees may die suddenly or languish for 2–4 years. The symptom most characteristic of sapstreak disease is yellowish-green stained wood that is also very moist. Once the wood is cut and dries, the stains turn light brown, so they're difficult to see and diagnose at that point.Disease CycleAs an ascomycete, Ceratocystis coerulescens produces ascospores encased as groups of eight in asci. The asci are protected by a perithecium, a flask-shaped ascocarp, in which the pathogen overwinters. Ascospores are the sexual spores and are far less common than the asexual spores known as conidia. The conidia form on conidiophores without a sporocarp. C. coerulescens has two mating types referred to as Mat-1 and Mat-2, but it is not a strictly heterothalic species. The Mat-1 type is self-sterile and must cross with Mat-2 to produce perithecia. However, the Mat-2 type is self-fertile and half of the progeny from a Mat-2 selfing are Mat-1.EnvironmentSapstreak disease has occurred only in North America and primarily in sugar bushes, stands of Acer saccharum that are tapped for maple sap. There has been a single report of it in Ontario, Canada; and cases in the U.S. have been from California, Michigan, Minnesota, New York, North Carolina, Vermont, and Wisconsin. As with all fungi, it requires a moist environment to sporulate.PathogenesisCeratocystis coerulescens enters its host through wounds, especially wounds in buttress roots and lower trunk. All diseased trees have been found to have man-made wounds from tapping and/or driving and dragging logs over them. Therefore it’s believed that the trees successfully combat the pathogen when it enters wounds higher up made by animals, insects, or weather. Sapstreak disease is commonly associated with the presence of opportunistic fungi Armillaria and/or Xylaria.ImportanceSapstreak threatens maple syrup production primarily, but also ruins the wood for making lumber. The economic and environmental damage due to this pathogen is currently meager. Most instances have occurred after incautious logging and have been well contained. Usually a single tree or a small group is affected.ManagementThe best way to manage this disease is to prevent it by avoiding injuries to the roots and lower stems of sugar maples. This can be accomplished by using the same, well-placed trails every year through the sugar bush and by using tubing systems instead of buckets to collect sap. When infection does occur, the tree should be cut down and the wood promptly removed to reduce inoculum.

The Elm sphinx, (Ceratomia amyntor), sometimes called the Four-horned Sphinx, is a North American species of moth in the Sphingidae family. It has a wingspan of 3¼ - 4½ inches (8.2 - 11.5 cm). As the name suggests, the larvae (caterpillars) feed on elm trees (Ulmus), but they can also be found feeding on birch (Betula), basswood (Tilia), and cherry (Prunus). When the caterpillars are ready, they crawl to the bottom of the host tree, where they crawl underneath the soil and pupate and may overwinter underground if late enough into the year. Vegetable growers should be aware of this larvae due to its insatiable appetite. One of these larvae are capable in devouring huge amounts of plant's foliage and even succulent stems.

Ceratophyllus coahuilensis

The Ceratolasmatidae are a family of harvestmen with eleven described species.The monophyly of this family is questionable; it is composed of three possibly monophyletic groups:Ceratolasma and Acuclavella are four to six millimeters long, with moderately short legs and short pedipalps. These two genera are closely related to Ischyropsalis (Ischyropsalididae).Hesperonemastoma species range from one to two millimeters in body length. They have similarities Nemastoma, which occurs in the Old World (hespero = "west" alludes to the occurrence in the New World). It seems to be more closely related to Taracus (Sabaconidae) than to Ceratolasma.Crosbycus has a body length of less than one millimeter. The pedipalps are long and very thin. Its moderately long legs are densely covered with setae, spikes and trichomes. Crosbycus should possibly be placed in its own family.

Ceratocystis wilsonii

Ceratogymna cylindricus

Ceratophaga vastella, or the horn moth, belongs to the clothes moth family Tineidae and is noted for its larva's ability to feed on keratin from the horns and hooves of dead ungulates, and occasionally on dried fruit or mushrooms. Keratin, a protein which makes up skin, hair, nails and feathers, is extremely resistant to proteolysis by the enzymes from specialised micro-organisms such as fungi and bacteria.Ceratophaga vastella is widespread in the Afrotropic ecozone. Thus far there are 16 described species in the genus, with 12 found in Africa, three in Asia and one, C. vicinella, from the Americas, which feeds on the shells of Gopherus polyphemus, a tortoise from the southeastern United States, but also feeds on the horns of cattle in the US.Larvae are cream-coloured and thick-set, with brown head and tip of abdomen. Usually the larval cases are noticed on the surface of old horns. The adult moth is a typical tineid, having a conspicuous tuft of yellow hair on the head. Other Tineidae share C. vastella's diet of keratin, dried animal hides and wool - C. ethadopa (Meyr.), Monopis rejectella (Wlk.), Tinea pellionella and Tineola bisselliella.According to the entomologist Thomas de Grey (1843-1919), the larvae of this species may occasionally be found in the horns of living animals.Mr. Haliday made some remarks on two pairs of antelope's horns, exhibited to the meeting by J. M. Neligan, M.D. These horns belonging, one pair to Oreas canna (pi. i., fig. 3), the other to Kobus ellipsiprymnus were brought home from the Gambia by J. Fitzgibbon, Esq., M.D., who lately purchased them from some natives in the market at Macarthy's Island, being struck with their appearance, as they were perforated by grubs enclosed in cases which projected abundantly from the surface of the horns, although these were taken from freshly-killed animals, the blood not having dried up on them when brought to market. The most remarkable point was the evidence that the horns had been thus infested while the animal was yet living which bore them. As the fibrous substance of the horn undergoes little or no change at the death of the animal, there seems to be no reason why the moth should not deposit its eggs when the living animal is at rest, nor why the larva should not penetrate the horn; but the question must be considered to be "sub judice".Zeller and Roland Trimen expressed their doubts about larvae feeding off the horn of a living animal and were supported in this view by Lieutenant Colonel the Hon. Wenman Coke, a soldier and hunter. Thomas de Grey also writes: "I have in my own collection a pair of horns of Kobus ellipsiprymnus, which are bored by the larvae of this species, the substance of the horn itself being visibly perforated in several places up to one-fourth from the base". This is a clear suggestion that the larvae do not confine themselves to keratin, but will also venture into the bony part of the horn.

Ceratodontes (From Greek keras (κέρας) (genitive keratos, κέρατος) meaning "horn" and from Ancient Greek ὀδούς (odoús) meaning "tooth") are structures consisting of Keratin, located in the mouth cavity, which functionally serve as teeth. They develop, unlike osseous teeth, through cornification from the epithelium of the oral mucosa.They occur in several forms:Conical Ceratodontes occur with CyclostomataPlate-shaped Ceratodontes occur among some mammals, who lost their osseous teeth. For example, they occur among platypodes, sirenians, and baleen whales.Rhamphotheca, which cover the jaw-bone, occur with anomodonts, turtles, and birds (beaks).

Ceratophora plutelliformis

Huntiella moniliformis is a saprobic fungal species that was previously accommodated in the Ceratocystis genus. Due to morphological, molecular and ecological differences, it was recently allocated to the newly described Huntiella genus. Species belonging to this genus typically do not cause disease on plants with the exception of H. bhutanensis. These species are almost always found on freshly cut timber or wounded trees.The MAT locus and sexual strategy of H. moniliformis was recently elucidated. Unlike its close relatives that are heterothallic, H. moniliformis exhibits a homothallic sexual strategy. It harbours only the MAT1-2-1 gene at its MAT locus and is thus an example of a unisexually reproducing species. Such species are able to produce sexual progeny even in the absence of typically essential mating genes.

Ceratophaga is a genus of moths belonging to the family Tineidae. There are currently 16 described species. Most species (12) are found in Africa with three found in Asia and one, C. vicinella, found in the southeastern United States.The larvae of most tineids (e.g. clothes moths) have adapted to feeding on non-herbaceous material, but Ceratophaga are especially remarkable in that they feed, apparently exclusively, on solid keratin from dead vertebrates. For most species this means the horns and hooves of ungulates but the North American C. vicinella feeds on the shells of the tortoise Gopherus polyphemus.

Ceratomia catalpae

Ceratophorus longipedicellata

Ceratopetalum gummiferum, the New South Wales Christmas bush, is a tall shrub or small tree popular in cultivation due to its sepals that turn bright red-pink at around Christmas time. The petals are actually small and white - it is the sepals that enlarge to about 12mm after the flower sets fruit and starts to dry out.The specific name gummiferum alludes to the large amounts of gum that is discharged from cut bark.

Ceratoperidinium margalefii, also known as Ceratoperidinium yeye, is a species of dinoflagellates. This species has two flagella.

Ceratomyrmex ellenbergeri

Ceratophaga vicinella is a species of moth belonging to the family Tineidae. It has a restricted range in the southeastern United States, mainly in Florida and Mississippi.This species appears to be in decline, almost certainly because the gopher tortoise (Gopherus polyphemus) is under threat; the moth relies on the tortoise in a unique way. All Ceratophaga larvae feed, uniquely among Lepidoptera, on solid keratin. Most species feed on the horns and hooves of dead ungulates but C. vicinella feeds exclusively on the shells of dead gopher tortoises.The larvae of C. vicinella, whitish with a dark brown head, feed gregariously on the keratin shells and construct a mass of silk tubes on the underside which act as anchors, penetrating the soil to a depth of 10 cm, possibly also serving to protect the larvae from temperature extremes and parasitoids. They feed, and eventually pupate, within the protection of these tubes.The adult is a fairly typical tineid, blackish brown with a tiny white spot on each forewing and a prominent tuft of cream-colored hair on the head.
