Caloplaca peregrina Samp., a species described from Portugal in 1917, and only known from the type localities, is synonymized with Caloplaca pellodella (Nyl.) Hasse. KEYWORDS. Caloplaca pellodella, Caloplaca peregrina, synonym, Portugal. ^ Gonçalo Sampaio (1865–1937) was the greatest Portuguese lichenologist of the beginning of the 20th century, as indicated by his 14 research articles on lichens, published between 1916 and 1924. These works are of paramount importance because the existing lichen records for Portugal prior to his time were scarce. Also, Sampaio started an important lichen collection as a result of his field trips, and this is now part of the reference collections of the herbarium at the Universidade do Porto (PO). Sampaio authored 103 new names of lichens, comprising one new genus, 60 new species, 14 new infraspecific taxa, 25 new combinations and two nomina nova (Paz-Bermúdez et al. 2002). However, most of the taxa described by Sampaio have not stood the test of time and have been synonymized by other authors. To date, of the 60 new species, only eight are in current use: Lecania badiella, Lemmopsis affinis, ^ ^ Lobaria mollisima (¼Erioderma mollisimum (Samp.) Du Rietz), Physma hispanicum (¼Lempholemma hispanicum (Samp.) Zahlbr.), Ramalina portuensis, Rinodina confinis, R. confragosa (Ach.) Körb var. olivieri (¼Rinodina santorinensis Steiner var. olivieri (Samp.) H. Mayrhofer & Sattler) and Rinodina lesdainii. Furthermore, there are about 20 taxa that can be referred as nomina inquirenda, because the type specimens are too small to be studied in detail. Among the species accepted in the Iberian checklist by Llimona and Hladun (2001) is Caloplaca peregrina Samp. This species was described by Sampaio (Sampaio 1917a) and later was transferred by him to Lecanora (Sampaio 1917b); the sole floristic or descriptive work dealing with this taxon since that time is by Clauzade and Roux (1985). These authors included the taxon in the genus Caloplaca on the basis of the original description as they were unable to find THE BRYOLOGIST 109(2), pp. 185–187 Copyright Ó2006 by the American Bryological and Lichenological Society, Inc. 0007-2745/06/$0.45/0 186 the bryologist 109(2): 2006 material elsewhere. These three bibliographic references are mentioned by Llimona and Hladun (2001). Clauzade and Roux (1985) included C. peregrina in the section Gyalolechia. In this group the species are characterized by spores with a small axial connexion between the cells (, 3 lm), and this in compliance with Sampaio’s description of the species in 1917, yet differs from his annotations on the type sheet and with our own observations of the type. Caloplaca pellodella (Nyl.) Hasse was described by Nylander as a species of Lecanora (in Hasse 1898). In Hasse’s publication, he included a series of new species mainly found in southern California and described by Nylander. Later, Hasse (1913) transferred the species into the genus Caloplaca. MATERIAL AND METHODS We re-examined type specimens of Caloplaca peregrina deposited in PO as well as additional material from the herbaria BCC and MIN. Some recent collections in SANT were also examined for comparative purposes. Several standard European floras and a few specific papers were used for identification. The specimens were studied microscopically, and identified by their anatomical, morphological and chemical characters. RESULTS Caloplaca pellodella (Nyl.)

Thallus consisting of thick lobulate areoles, grayish-green to olive, 6 raised or, more rarely, areolate, pale gray, and 6 shiny depending on the thickness of a dead upper layer of 5–10 lm covering the thallus; upper cortex thick, 25–50 lm. Both necrotic layer and cortex becoming thinner towards the tips of the lobes. Apothecia 0.25–1.1 mm, rarely immersed when young, but clearly sessile when mature, with a distinct thalline margin, becoming thinner and slightly sinuose with age. Disc yellow in the light gray thalli to dark orange or buff in material with darker thalli. Hymenium colorless, 55–80 lm, hypothecium also colorless and the parathecium consisting of elongate cells. Ascospores 8/ascus, polarilocular and colorless, (n ¼ 30) 8.75–13.25 3 5– 6.25 lm, septum 2.5–3.75(

Distribution. Known from various countries in the Mediterranean region as well as the U.S.A., China, India and the Canary Islands (Wetmore 1996). DISCUSSION Tavares (1961) previously synonymized C. peregrina with C. conglomerata, although he had not examined type material; this synonymy was overlooked by later authors. Furthermore, C. conglomerata was more recently synonymized with C. pellodella by Wetmore (1996). According to this author, the European collections referred to as C. conglomerata can be separated from North American collections by the smaller lobules and Paz-Bermúdez et al.: Caloplaca peregrina thinner necrotic layer and cortex. However, material re-examined for this study showed that these characters can vary and there is not a clear distinction between the European and North American taxa. The species, though, can be recognized easily by its sublobulate thallus, the presence of a necrotic layer, thick cortex and the type of cellular tissue of the parathecium. Material collected by Sampaio, and subsequently by us, was on river margins, yet we were unable to find a correlation between the degree of areolation and thallus color and the distance from the water. 187 Hasse, H.E. 1898.
