| description | A very thin crustose Codium, occurring in the southern part of the Gulf of California and along the tropical Pacific coast of Mexico southward to Panama, Colombia, and the Galapagos Islands, is described as a new species, C. picturatum F.F. Pedroche et P.C. Silva. Its anatomy is very different from that of other crustose species, including C. hubbsii Dawson and C. setchellii Gardner, two members of the C. adhaerens group known from Pacific Mexico. In that group, daughter utricles are produced by budding from parent utricles, resulting in clusters that are easily separated by dissection. In C. picturatum daughter utricles are formed at the end of filaments produced by parent utricles, as in erect, branched thalli, but with most filaments being shortened, some to the point that daughter utricles are borne directly on the parent utricle. The medullary filaments are tortuous and closely branched, so that dissection of the thallus is difficult. |

Pedroche et P.C. Silva, que crece desde la parte sur del Golfo de California a lo largo de la costa tropical del Pacífico mexicano, Panamá, Colombia y las Islas Galápagos. Anatómicamente es muy diferente del resto de las especies costrosas, incluyendo C. hubbsii Dawson y C. setchelli Gardner, dos miembros pertenecientes al grupo de C. adhaerens conocidos con anterioridad para el Pacífico de México. En estas especies, utrículos hijos se producen por gemación de los utrículos parentales y forman agrupamientos que son fáciles de separar por disección. En C. picturatum, los utrículos hijos se forman en el extremo de filamentos producidos por los parentales, como ocurre en las especies de talos erectos y ramificados, pero la mayoría de los filamentos se encuentran acortados a tal punto que los utrículos hijos nacen directamente sobre el que los origina. Los filamentos medulares son tortuosos y ramificados cercanamente, lo que dificulta la disección del talo.
