Líquenes y hongos liquenícolas de la Serranía de Ronda (Málaga-Cádiz), sur de España
2017
As a result of a field trip organised by the Spanish Lichen Society in Serranía de Ronda, south Spain, a catalogue of 360 taxa is presented (336 lichens, 24 lichenicolous fungi). The list includes three new records for the Iberian Peninsula: Arthonia paretinaria, Micarea myriocarpa and Niesslia keissleri, 51new ones for the Autonomous Andalusian Community, and three and 81 new ones for the province of Cádiz and of Málaga, respectively. After these results, the total updated number of the province of Málaga rises to 556 lichens and lichenicolous fungi. The best represented lichen genus is Cladonia (18) with the most species, unlike Lecanora (15), Pertusaria (12), Physconia (12) and Collema (…
Diversidad liquénica asociada a fenómenos post-incendio en los alcornocales valenciano-castellonenses.
2001
FOS, S., CALATAYUD, A. & BARRENO, E. 2001. Lichen diversity associated with post-fire colonization in the Valenciano-castellonense cork-oak forests. Bot. Complutensis 25: 103113. 103 Simón Fos et al. Diversidad liquénica asociada a fenómenos post-incendio... The post-fire colonization of the burned barks of cork-oaks (Quercus suber L.) by epiphytic lichens affected by fire episodes has been studied in different areas of the Valenciano-castellonense cork-oak forests (Asplenio onopteridis-Querco suberis sigmetum). These forests, which have been affected by fires of different intensity, are located in Espadán and Calderona mountains and in the Desierto de Las Palmas and differ with respect…
Clinical features of oral lichen planus. A retrospective study of 65 cases
2010
Objectives: To describe the clinical features of patients diagnosed with oral lichen planus (OLP) and to establish the prevalence of its malignant transformation in our setting. Study design: A retrospective study was made of 65 patients clinically and histologically diagnosed with OLP in the Service of Oral Surgery (Dental Clinic of the University of Barcelona, Spain) in the period 1990-2005. A descriptive and bivariate statistical analysis was made. Results: The mean patient age was 59 years (SD ± 14.9). Most of the patients (61%) were women, and the most frequent location of the lesions was the buccal mucosa (90.8%). White forms of OLP were noted in 66% of the cases, and 46.2% of the pat…

Four lichen species new to Spain
2003
Se presentan cuatro nuevas citas de líquenes de España, concretamente Aspicilia ruceniuro, Lecanora stenotropa, Vezdaea leprosa y Xanthoparmelia plitii. Las especies probablemente no son raras pero habían sido obviadas, bien por ser inconspicuas bien por ser similares morfológicamente a otras especies. Four species of Lichens are reported as new to Spain, namely Aspicilia moenium, Lecanora stenotropa, Vezdaea leprosa aud Xanthoparmelia plitii. The species are probably not rare, but overlooked, since they are either inconspicuous or morphologically similar to other species. Eva.Barreno@uv.es

Bacterial communities associated with the lichen Ramalina farinacea (L.) Ach.: composition, biodiversity and biotechnological potential
2017
Los líquenes son un ejemplo clásico de asociación simbiótica autosuficiente, compuesta por, al menos, un hongo filamentoso (micobionte, heterótrofo) y cianobacterias y/o algas verdes unicelulares (fotobiontes, fotosintéticos). Se desarrollan gracias a la combinación adecuada de hongos y algas y/o cianobacterias, y sus talos son los fenotipos resultantes (holobiontes). Dicha asociación les permite colonizar y crecer en ambientes diversos y extremos que no podrían habitar los simbiontes de forma independiente. Estudios recientes, mediante aproximaciones ómicas, han revelado la gran abundancia y diversidad de las comunidades bacterianas asociadas a los líquenes. Estos estudios han cambiado la …
