A continuación, se realiza su respectiva descripción: basidioma estipitado, lignicola, principalmente gregario, en ocasiones solitario o cespitado, no higrofano, píleo de 5 a 7 cm de diámetro, hemisférico en un principio, luego pasa a ser plano convexo con el centro umbonado, orbicular (vista apical). Margen recto, entero y ligeramente ondulado, de superficie glabra, viscida y brillosa, que luego pasa a ser seca y opaca, de color rojo que tiende a oscurecerse con el tiempo, con escamas blancas y fasciculadas en el margen, originadas por restos del velo universal. Himenio con lamelas y lamélulas, se encuentran próximas entre sí (apretadas), adnadas a ligeramente uncinadas, anchas, de borde liso, lamélulas atenuadas, de color café claro principio, después gris violáceo y finalmente púrpura negruzco, arista entera, blanquecina. Contexto homegeneo y hueco. Esporada de color marron oscuro.
Estípite de 4-8 cm de largo x 0.4-0.5 cm de ancho, cilíndrico, central, sub-bulboso y con tomento basal con cordones miceliares (rizomorfos), de color blanco con zonas de color naranja rojizo que se intensifica con el tiempo, de superficie pruinosa. Se engrosa ligeramente hacia la base. En algunos ejemplares se logra observar un anillo en banda (rudimentario) adherido al estípite, delgado y efimero. De consistencia fibrosa. Sin olor o sabor apreciable. Basidiosporas elipsoidales, lisas, de paredes gruesas, con poro germinal.
El trabajo de microscopia se realizó con un Microscopio Zeiss de Luz Halogena 6v 30w y reactivos rojo congo, melzer e hidróxido de potasio (KOH) 5%. Se observan basidios tetraspóricos, claviformes de 31 x 8 µm, basidiosporas elipsoidales no amiloides, de color marrón a rojo oscuro, superficie lisa, ligeramente apiculadas, con poro germinativo evidente (0,8 a 1 µm). Cistidios fusiformes, de 35,7 x 12,7 µm en general se observan hifas paralelas y presencia de fíbulas.

Otras consideraciones de la especie: respecto al valor nutricional no se reconoce alguna propiedad, sin olor o sabor destacable. Su comestibilidad no está especificada o se le reporta como "desconocido" (Courtecuisse, Duhem, 2007; Arora, 1986; Desjardin, Wood, Stevens, 2014; Trudell &Ammirati, 2009; Gerhardt y Grzyby, 2006). Por otra parte, los análisis de Anastos et al. (2008) sugieren que L. ceres contiene psilocibina en cantidades relativamente grandes (9,700-9,900 mg/kg peso seco).
Tomando como referencia los registros de los autores y los consolidados en la plataforma iNaturalista y gbif.org, la especie ha sido observada en Cota Cundinamarca, Engativá Bogotá D.C., Humedales del noroccidente de Bogotá (Humedal La Conejera, Humedal Cordoba, Humedal Tibabuyes, Humedal Torca-guaymaral), Humedal Santa Maria del Lago, Jardín Botánico José Celestino Mutis Bogotá D.C., Parque El Virrey Bogotá D.C., Parque La Florida Cundinamarca,Villamaría Caldas.

so instead of calling the number on the side of the machine worth several thousands of dollars, jeff and pat decided to just open it up and fix it themselves. 2 days later, we found it was a blown fuse.....they are happy they saved money. i still think we should have called an expert.
Polyacrylamide is a polymer composed of acrylamide subunits (-ch2chconh2 -). It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N'-methylenebisacrylamide. In the cross-linked form, the probability for the existence of the monomer is further reduced. It is highly water-absorbent, Soft glue is formed when hydrated., used in such applications as polyacrylamide gel electrophoresis, and also be called as ghost crystals when cross-linked, in manufacturing soft contact lenses. In the straight-chain form, it is also used as a thickener and suspending agent. Recently, it 's used as a subdermal filler for aesthetic facial surgery (see Aquamid).

2.Introduction of Nano Lift
Anti-aging focus on eye care products, 73% of the eye care products have claimed to be anti-aging. 62% of eye care products have claimed they can reduce wrinkles and fine lines
NanoLift is composed by plectranthus barbatus root extract and synthetic peptide acetyl dipeptide-1 cetyl ester combined with nanotechnology, which has fast penetration and efficiency. Significant improvement in wrinkles can be observed immediately after using.
The chemical compositions of plectranthus barbatus is diverse and has been
isolated from roots and overground parts, including terpenoids, flavones, sterols, volatile oils, etc. Nano Lift used the root extract of plectranthus barbatus.
Acetyl dipeptide-1 cetyl ester has very good stimulation effect on the synthesis of elastin. In vitro research, Nano Lift has bounced deposition of elastin fiber and elastin to 94% in the extracellular matrix. Nano Lift acts on each stage of elastic tissue formation. Elastic tissue does not only have elastic proteins, but also made up of a variety of proteins.
Features of Nano Lift
1. Nano Lift has good thermal, pH and shear stability, easy to use.
2. Nano Lift has significantly improved the stability and bioavailability.
3. Nano Lift can greatly enhance the absorption.
4. Nano Lift is 100 % water soluble and 100% oil soluble (amphipathy) with wide range of application.
5. The raw material of Nano Lift meet the FDA GRAS standard
