Some lichens from the vicinity of Ribeiro Frio (Madeira, Macaronesia) Ivan PIšút Institute of Botany, Slovak academy of Sciences, Dúbravská cesta 14 SK- 845 23 Bratislava, ivan.pisut@savba.sk Pišút I.: Some lichens from the vicinity of Ribeiro Frio (Madeira, Macaronesia). acta Mycol. 44 (2): 179–184, 2009. a list of 49 lichens recently collected in the vicinity of Ribeiro Frio in Madeira is given. the species Ramalina nodosa and Peltigera neckeri are probably new to the island. Collections of Cladonia stereoclada, Hypogymnia madeirensis, Megalospora maderensis, Peltigera degenii and Phlyctis agelaea are interesting as well. Key words: lichenized fungi, Madeira, Portugal IntRoDuCtIon Madeira is a Portuguese island in the atlantic ocean, 900 km SW of Portugal and 660 km nnW of the Canary Islands (Fig. 1). In winter 2002 and 2003 I had an op- portunity to study lichens at some localities during my short holidays in Madeira (Pišút 2004). In 2008 and 2009 I visited the island again and studied the lichens of the laurel forests near the habitation of Ribeiro Frio situated below Poiso, a moun- tain transition in the northern part of the island on the road between Funchal and Santana. In 2008 I studied the lichens along the levada between Ribeiro Frio and Portello (1), in 2009 on the levada between Ribeiro Frio and Balcões (2) and in the laurel forest above the habitation (3). the material is preserved in my herbarium and in lichen collections of the Institute of Botany, Slovak academy of Sciences, Bratislava (Sav). aCta MYCoLoGICa vol. 44 (2): 179–184 2009 Dedicated with pleasure to Professor Krystyna Czyżewska not only for her significant contribution to the knowledge and conservation of Polish lichens, but also for her activities in cooperation networks of Central European lichenologists 180 I. Pišút ReSuLtS anD DISCuSSIon Data on 49 lichen species are presented. the species Ramalina nodosa and Peltigera neckeri are probably new to the island; other findings, e.g., Cladonia stereoclada, Hy- pogymnia madeirensis and Megalospora maderensis, are also interesting. Byssoloma leucoblepharum (Nyl.) Vain. − on leaves of Laurus azorica above Ribeiro Frio, alt. ca 920 m (3). B. subdiscordans (Nyl.) P. Jameson − on leaves of Laurus azorica 2 km east of Ribei- ro Frio, alt. ca 830 m (1); on leaves of Laurus azorica and Ilex canariensis above Ribeiro Frio, alt. ca 900 m (3). Cetrelia olivetorum (Nyl.) W. L. Culb. & Ch. F. Culb. − on tree bark (Lauraceae) ca 1 km east of Ribeiro Frio, alt. 850 m (1). Cladonia rangiformis Hoffm. − among mosses on basaltic rocks, ca 2 km eastwards, alt. 830 m, and near Ribeiro Frio, alt. 880 m, 2008 (1); C. stereoclada des Abb. − on mossy basaltic rocks ca l km, alt. ca 850 m, and on earth ca 2 km, alt. ca 830 m, east of Ribeiro Frio (1); on mossy basaltic rocks above Ribeiro Frio, alt. ca 900 and 920 m (3), sparse. this Macaronesian endemic species was described by des abbayes (1946) from the Faial island in the archipelago of the azores. He characterized it as follows: “Cette intéressante espèce est incontestament voisine de Cl. furcata, notamment par ses réactions et ses conidanges. Mais elle en est distincte par ses podétions beacoup plus ténus, semi-pellucides, et surtout par sa couche chondroïde formant un axe plein, et lorsque´elle est creuse, toujours très épaisse par suite de l´exigüité de la cavité centrale”. C. stereoclada was recorded in Madeira by tavares (1952) for the first time (4 localities on mossy earth at alt. 828−1000 m) and in the Canaries by Østhagen and Krog (1976). Fig. 1. Sketch map of Madeira. areas above 1000 m altitude within the internal line. adapted from arvidsson and Wall (1985). Some lichens from Ribeiro 181 Degelia plumbea (Lightf.) P. M. Jørg. & P. James − on humid basaltic rocks and on tree bark (Lauraceae) 2 km east of Ribeiro Frio, alt. 830 m (1). Fellhanera bouteillei (Desm.) Vězda − on leaves of Laurus azorica 2 km eastwards, alt. ca 830 m (1), and above Ribeiro Frio, alt. ca 920 m (3). Heterodermia leucomelos (L.) Poelt − on branches and the bark of various laurels and on mossy basaltic rocks, alt. 850-880 m (1), on the bark of various Lauraceae, alt. 900 m; abundant (3). Hypogymnia madeirensis (Tav.) Hawks. − on dry branches of a deciduous tree (Lau- raceae) ca 2 km east of Ribeiro Frio, alt. ca 830 m (1). My specimen lacks soredia, contains a few stalked apothecia and its medulla is PD−. H. madeirensis shows some superficial similarity to H. tavaresii, but the latter is larger and its medulla reacts PD+ bright yellow (Hawksworth 1973). tavares (1952) recorded this spe- cies (as Parmelia madeirensis) from its locus classicus (“Inter Queimadas et Cal- derario verde, ad ramos Ericae circ. 900 m s. m. 9−VIII−1951”). Hypotrachyna endochlora (Leight.) Hale − on Ocotea foetens bark ca 1 km east of Ribeiro Frio, alt. ca 850 m (1). From Madeira for the first time recorded by arvidsson and Wall (1985) in Ribeiro Frio; H. laevigata (Sm.) Hale - on mossy basaltic rocks ca 2 km east of Ribeiro Frio, alt ca 830 m (1).

Probably already recorded by tavares (1964, as H. taylorensis). H. pulvinata is absent in Madeira in Hafellner´s check- list (1995), but it occurs there according to Schumm (2008). the only difference between H. pulvinata and H. taylorensis is the upper surface of older specimens of the latter with occasional irregular white abraded areas. they are probably symptoms of altering according to Schumm (l.c.). RemaRk. If both species are identical, the binom Parmelia pulvinata Fée 1824 has priority against Parmelia taylorensis M. e. Mitsch. 1961; H. rockii (Zahlbr.)

Megalospora maderensis (Krempelh.) Sipman − on the bark of Ocotea foetens ca 1 km east of Ribeiro Frio, alt. ca 850 m (1). this rare endemic species in Madeira is characterized with by bacillar spores, the presence of clearly thickened edges around the spore septa and the presence of 182 I. Pišút usnic acid (Sipman 1983). It occurs at elevations from 850 to 1000 m on bark and rock (tavares 1952, as Bombyliospora amplificans var. maderensis). Nephroma foliolatum P. James & F. J.
