As a result of collections made in 61 locations during the year 2018, the number of Cladonia taxa is enlarged to 42, and ten new records of Cladonia are provided to Montenegro, Cladonia cariosa, C. coccifera, C. cyathomorpha, C. digitata, C. diversa, C. homosekikaica, C. imbricarica, C. merochlorophaea, C. novochlorophaea and C. subulata. The distribution of many taxa previously known for the territory is extended. The chemical variation and the distribution of each species are discussed. Key words.

Como consecuencia de la recolección en 61 localidades efectuada en 2018, se amplía a 42 taxones del género Cladonia, además se aportan diez especies nuevas para Montenegro, Cladonia cariosa, C. coccifera, C. cyathomorpha, C. digitata, C. diversa, C. homosekikaica, C. imbricarica, C. merochlorophaea, C. novochlorophaea y C. subulata. Se amplía la distribución de muchos de los taxones citados con anterioridad para el territorio. Se discute la variabilidad química y la distribución de cada una de las especies encontradas.
