Exempel på hur man kan använda COLLARETTES i en mening

• The egg is elongate and tapers towards both ends, and surrounded by helically twisted collarettes, with one end (the beak) having a tendril.
• They display a conspicuous right-handed spiral of collarettes around the body, and in some cases, the pedicle, resulting in a rhomboidal pattern when flattened during fossilisation.
• Prior to analysis by scanning electron microscope, the conidiogenous cells were observed to form from non-annelated phialides and phialides without collarettes.
• The production of slimy, orange- to salmon-colored colonies on short adelophialides (phialides lacking a basal septum) with cylindrical collarettes can be quite distinct, with ventricose phialide formations less frequent.
• Conidiophores bearing one-celled conidia like those produced by Rhinocladiella, branched chains of one-celled conidia arising from erect conidiophores like those produced by Cladosporium, and flask-shaped phialides having flared collarettes and balls of one-celled conidia like those produced by Phialophora may also be present.
• Conidiogenesis occurs at inconspicuous loci along hyphae; a basipetal (chain of conidia in which new spores are formed at the base) succession of blastically produced conidia leave behind conspicuous collarettes that are remnants of the initial outer wall of the conidia; these accumulate centripetally to form a multi-layered collarette appearing similar to annellations (Goh & Hyde 1998).
• Conioscypha (the sole genus in the Conioscyphales) is generally characterised by aseptate, dark brown conidia and a unique mode of blastic conidiogenesis, when conidia are born in cyathiform (in the form of a cup, a little widened at the top) to doliiform (shaped like a barrel or cask) blastic conidiogenous cells surrounded by hyaline (transparent), cup-like collarettes with a multilamellar (having (or affecting) multiple lamellae) structure (Shearer & Motta 1973).
