La presencia de acúmulos minerales masivos ha sido observada en tejidos de diversas especies de musgos. Se ha estudiado la morfología de estas mineralizaciones con microscopia electrónica de barrido (MEB) y de transmisión (MET); así como su composición mineralógica, a través de análisis de difracción de rayos X (XRD), tanto locales, empleando sondas acopladas a MEB y MET, como generales. Los resultados permiten concluir que la deposición mineral masiva en los tejidos es un fenómeno generalizado en musgos. Se han identificado tres tipos morfológicos de depósitos: acúmulos minerales amorfos, granulaciones cristalinas y mineralizaciones aciculares. Aunque el mecanismo de biomineralización no ha sido investigado, los estudios mineralógicos comparativos parecen apoyar la hipótesis de una toma pasiva a corta distancia de minerales en disolución procedentes del substrato, que en el interior de los tejidos precipitan en formas metaestables. Por último, se discuten las posibles ventajas que la presencia de estos depósitos masivos pueden reportar a los musgos. We have observed the presence of massive mineral accumulations in the tissues of diverse moss species. The morphology of these mineralizations was observed using SEM and TEM, and their mineral composition was studied by means of X–ray diffraction analyses, both local, using X-ray probes coupled to SEM and TEM, or general. The results allow us to conclude that massive mineral deposition is a generalized phenomenon in mosses. We have identified three morphological types of deposits: amorphous mineral crusts, crystalline granulations and acicular biomineralizations. Although the mechanism of biomineralization has not been investigated, our mineralogical comparative studies support the hypothesis of a passive uptake at short distance of mineral solutes from the substrate. These minerals would precipitate later in the tissues as metastable forms. Finally, we discuss the possible advantages of the presence of these massive deposits for mosses.
