THE SAXICOLOUS SPECIES OF THE GENERA RINODINA AND RINODINELLA LACKINGSPOT-TEST REACTIONS IN THE IBERIAN PENINSULA

The morphology, anatomy, chemistry, ecology and distribution of twenty Iberian saxicolous Rinodina and Rinodinella species lacking spot test reactions are discussed, namely Rinodina bischoffii, R. calcarea, R. cana, R. castanomela, R. dubyana, R. gennarii, R. guzzinii, R. immerse , R. insularis, R. interpolata, R. lecanorina, R. luridata, R. milvina , R. obnascens, R. parasitica, R. rinodinoides, R. teichophila, R. tun icata, Rinodinella controversa and R. dubyanoides. ''Buellia'' parvula of uncertain taxonomic position is also included. New data on Rinodin a sicula and R. epimilvina, two species containing secondary lichen co mpounds, are also provided. Rinodina iodes s. lat. is a synonym of R. luridata, R. orcularia of R. bischoffii and R. orculariopsis of R. sic ula. The new combination Rinodina bischoffii var. castanomelodes is pr oposed. Rinodina interpolata, R. parasitica and R. sicula are reported for the first time from the area studied. A special note on the hithe rto misunderstood Rinodina amoldii is given. Some illustrations and a key to the species are included.
