Abstract
Cladonia gracilis subsp. gracilis and Cladonia uncialis subsp. biuncialis are newly recorded to Toledo province. Furthermore, the distribution of C. macilenta and C. diversa is extended in this province. The habitats and distribution of these species in the Iberian Peninsula are discussed.
Highlights
The genus Cladonia is one of the most relevant genera of terricolous macrolichens
Up to date 73 species of Cladonia are known to grow in the Iberian Peninsula
Most of the diversity concentrates in the Eurosiberian region; as regards the Mediterranean region, the supramediterranean belt, along with some humid enclaves with a submediterranean climate, harbour most of the genus diversity
Summary
The diversity and distribution in the Iberian Peninsula of the species within this genus is well studied (Burgaz & Ahti 1991, 1994, 2009; Burgaz et al 1999). Up to date 73 species of Cladonia are known to grow in the Iberian Peninsula. The lichenized mycota of Toledo province has been relatively well studied (Martínez et al 1993; Vázquez & Burgaz 1996; Aragón & Martínez 1997; Aragón et al 2001, 2006), especially the epiphytic lichen forming fungi. Sixteen species of the genus Cladonia have been reported. The eastern massifs of Montes de Toledo range, namely Rocigalgo and Chorito, are the most studied in detail. The western sector, where Sevilleja and Altamira ranges lie, has been less explored. In some humid enclaves of the Sierra de Sevilleja, a few patches of relict forests from the Tertiary are preserved, with Taxus baccata L. and Prunus lusitanica L., while the Sierra de Altamira still retains some well preserved Quercus pyrenaica Willd. oakwoods
