Box 7, FI-00014 University of Helsinki, Finland Abstract — The third, updated electronic version of the world list of cetrarioid lichens (http://esamba.bo.bg.ut.ee/checklist/cetrarioid/home.php) contains more than 570 names representing 149 accepted species. It is based on a FileMaker powered database, allowing users to view data in different sets and to perform searches. The list presents new information about the phylogenetic status of accepted taxa, and about the type materials for most of the names. A concise list of the cetrarioid lichens displayed below includes all the currently accepted 25 genera and 149 species which are now or have earlier been considered to be cetrarioid; taxa belonging to the monophyletic cetrarioid core group (17 genera and 101 species) are pointed out. A new combination Nephromopsis sikkimensis is proposed and some nomenclatural details discussed. Cetraria / database / Nephromopsis sikkimensis / nomenclature / Parmeliaceae / phylogenetic status INTRODUCTION ‘Cetrarioid lichens’ is a colloquial term used for indicating a morphological group of taxa within Parmeliaceae (Lecanorales, Ascomycota), the largest family of lichen-forming fungi with circa 2700 species and 80 genera. The group is defined by an erect foliose or subfruticose growth form of the thallus being loosely attached to the substrate, presence of marginal apothecia and pycnidia, and production of the Cetraria-type lichenan (Elix, 1993; Kärnefelt et al., 1992; Randlane & Saag, 1993, 1998a; Randlane et al., 1997). The cetrarioid group as a whole has been proved to be polyphyletic while a core group of it represents a strongly supported clade comprising the majority of cetrarioid genera, and, in addition, a few representatives from another morphological group, parmelioid, within the family (Nelsen et al., 2011; Thell et al., 2009). Some genera which have been morphologically identified as cetrarioid, belong phylogenetically, however, to the parmelioid * Corresponding author : Tiina Randlane. doi/ 10.782/crym.v34.iss1.2013.79 80 T. Randlane, A. Saag, A. Thell et al. core group (Amo de Paz et al., 2011; Blanco et al., 2006; Crespo et al., 2007, 2010). Thus, the common terminology can be easily misinterpreted, and it is essential to distinguish between the colloquial terms ‘cetrarioid (or parmelioid) lichens’ denoting polyphyletic groups of taxa delimited according to the “gross morphology”, and the phrases ‘cetrarioid (or parmelioid) core group (or clade)’ indicating certain phylogenetically delimited lineages. The investigation of cetrarioid lichens started historically in 1803, with the description of the genus Cetraria by Erik Acharius, followed by the gradual increase of the genus from 8 species up to 76 (Rassadina, 1950), and then the continuous splitting of it into over 20 segregates – based mainly on phenotypic traits, including morphological and chemical characters – during three decades, in 19601990s (Kärnefelt, 1979; Randlane & Saag, 1998a). The process of recombining cetrarioid taxa in other genera or synonymizing the names is still in progress, now predominately derived from the phylogenetic DNA analyses (Mark et al., 2012; Nelsen et al., 2011; Thell et al., 2005, 2007). In the group of cetrarioid lichens, nearly one hundred new names had been proposed during the past half-century, while numerous earlier names have turned into synonyms. Understandably this causes frequent misunderstandings and errors in use of the names of those lichens. To contribute to the better knowledge of cetrarioid group of lichens and being inspired by a manuscript “List of epithets in the parmelioid genera” prepared and distributed by Mason E. Hale in 1989, we compiled a similar list of epithets for the cetrarioid species. In its first, printed version (Randlane & Saag, 1993), over 200 species epithets were introduced in alphabetical order representing 120 cetrarioid species. For each epithet the accepted generic location and valid name was indicated. Altogether 36 species were pointed out as taxa with unacceptable generic location or insufficient information available. In the second printed version (Randlane et al., 1997) and its electronic updates from 2000 and 2002 (http://www.eseis.ut.ee/synonyms/cetraria.html) nearly 500 epithets representing 138 accepted species in 23 genera were listed. As a novelty compared to the first version, bibliographical data were provided for each combination. Altogether 17 species were specified as poorly studied and/or inadequately located. During the last ten years no updates for this checklist have been provided. The present, third version of the world list of cetrarioid lichens contains 572 names representing 149 accepted species. Its full edition is presented in electronic form, as it is based on a database, allowing users to view data in different sets and to perform searches. The list offers new information about the phylogenetic status of accepted taxa (e.g., whether they belong to the cetrarioid core group or not), and about the type materials for most of the names. RESULTS Functioning of the electronic checklist and the users’ interface. The third world list of cetrarioid lichens (Randlane et al., 2013 – last update on 20 January 2013) is freely accessible at the web portal eSEIS, an Estonian information system of lichens (http://www.eseis.ut.ee/index_en.html); both the computer version (http://esamba.bo.bg.ut.ee/checklist/cetrarioid) and smartphone version (http:// esamba.bo.bg.ut.ee/checklist/cetrarioid-mob) are available. The list is based on a FileMaker powered database and the web interface uses PHP programming language. It has been tested with all major web browsers, including Google Chrome, Internet Explorer, Mozilla Firefox, and Safari on various operating systems. 3rd world list of cetrarioid lichens 81 The current database model enables users to perform different operations: (a) view data in different sets; (b) perform simple search by different fields (e.g. names of accepted species, current status of the name, phylogenetic status of accepted taxa, type information, etc.); (c) perform complex search when indicating certain states in more than one field; (d) sorting according to certain fields – lists compiled by functions ‘Find’ or ‘Find All’ can be sorted by clicking the header of any column on the list. More detailed instructions (together with screenshots of the users’ interface) for using the electronic third world list of cetrarioid lichens are available in Saag et al. (2013). List of accepted taxa, including bibliographic and type information. The checklist includes all currently accepted genera and species which have ever been considered cetrarioid, 25 genera and 149 species altogether. The names of genera which belong to the monophyletic cetrarioid core group (Nelsen et al., 2011) are in BOLD CAPITALS; other included genera do not belong to this core group but have traditionally been treated as ‘cetrarioid’. The name of the type species of each genus is in bold. The names of species which have no phylogenetically satisfactory generic position according to the latest DNA analyses of the cetrarioid core group (Thell et al., 2009; Nelsen et al., 2011) are marked with an asterisk (*). The names of species which have not been examined or which are too insufficiently investigated (could be synonyms or belong to genera outside of the cetrarioid core group), are marked with a question mark (?) on the list. The full list of epithets which have been applied to these species, containing 572 records, is available online. AHTIANA Goward, Bryologist 88: 370. 1986 [1985] * A. aurescens (Tuck.) Randlane & A.

Knowledge about the shortage in information would help to improve the situation. Nomenclatural issues (1) The name Tuckneraria sikkimensis Divakar & Upreti turned out to be formally inadequate, therefore a new combination for this taxon is proposed below. Nephromopsis sikkimensis (Divakar & Upreti) Randlane & Saag, comb. nov. MycoBank: MB 803356. Basionym: Tuckneraria sikkimensis Divakar & Upreti in Bot. J. Linn. Soc. 150: 249. 2006. Type: India, Sikkim, Yumthang; Upreti, Chatterjee & Divakar 04-004112; 2004 (LWG, holotype). The genus Tuckneraria Randlane & A. Thell was submitted in 1994 as a segregate from Nephromopsis, mainly based on anatomical characters in the reproductive structures, such as spherical shape of ascospores and traits of exciple and asci, but also on a character in gross morphology, the presence of cilia 3rd world list of cetrarioid lichens 91 (Randlane et al., 1994; Randlane & Saag, 1998b). The species T. sikkimensis was described in 2006 within Tuckneraria (Divakar & Upreti, 2006), although a year earlier this entire genus had been synonymized with Nephromopsis based on a three-locus phylogenetic analysis (Thell et al., 2005). The authors of the new species discussed its taxonomic position and accepted that the citriform shape of pycnoconidia caused doubts for its generic position, and referred to the necessity of molecular approach in solving the problem (Divakar & Upreti, 2006). Our attempts to obtain DNA sequences from the isotype material (LWG) have not been successful, but we still propose to transfer this species to Nephromopsis, for the time being, as the name Tuckneraria sikkimensis is not acceptable any longer. The species is very rare and has been collected only twice in North Sikkim, India, so far. (2) Some minor changes in the author citation are introduced in cases when a name had been ascribed to another person by the publishing author. Lichenologists and botanists have not paid sufficient attention to the changes made in Article 46 in the Melbourne Code (McNeill et al., 2012) in recent decades. Art. 46.4 clearly states: “When the epithet of a validly published name is taken up from and attributed to the author of a different binary designation that has not been validly published, only the author of the validly published name is to be cited”. When this rule is followed, the following changes of author citations may be accepted: • Cetraria australiensis Kärnefelt, not C. australiensis W.A. Weber ex Kärnefelt; • Cetrariella delisei (Schaer.) Kärnefelt & A.Thell, not C. delisei (Bory ex Schaer.) Kärnefelt & A. Thell; • Cetrariella fastigiata (Nyl.) Kärnefelt & A. Thell, not C. fastigiata (Delise ex Nyl.) Kärnefelt & A. Thell. In these cases the validating authors themselves ascribed the names (erroneously) to other persons because they had used the cited epithet – but in a different taxonomic position. For example, Coelocaulon australiense W.A. Weber. as “n. sp.” was already published, but not validly so, by Weber (1975) in his exsiccata list and on labels. Kärnefelt, describing Cetraria australiensis, pointed this out (Kärnefelt, 1979: 67) but considered the name Coelocaulon australiense unpublished. The situation is similar to that described in the Melbourne Code in Art. 46.4. Ex. 24 (McNeill et al., 2012). (3) The effective publication date of Ming-Jou Lai’s important articles on Hypogymnia and on cetrarioid lichens in Quarterly Journal of Taiwan Museum vol. 33(3,4), pp. 209–214 and 215–229 (Lai, 1981a, b), accordingly, is usually miscited as “December 1980”, as written on the paper copies of the journal. These articles were actually distributed in January 1981. Article 29.1 in the Melbourne Code (McNeill et al., 2012) clearly states: “Publication is effected, under this Code, by distribution of printed matter (through sale, exchange, or gift) to the general public or at least to scientific institutions...”. The cited papers by Lai were parts of his Ph.D. thesis, and the opponent, Prof. Pekka Isoviita, pointed out the correct dates during the defence on 25 September 1981 at the University of Helsinki, Finland. The publication date was investigated in detail because a new genus, Ahtia M.J. Lai was published in the latter article with Sticta wallichiana as type, and almost simultaneously (“December 1, 1980”) Syo Kurokawa published the new genus Cetrariopsis Kurok. with the same lichen as type. Then it turned out that Cetrariopsis was published more than 1 month earlier and Ahtia fell into synonymy, which is widely accepted. However, the erroneous publication date is usually cited in later papers by Lai and others. 92 T. Randlane, A. Saag, A. Thell et al. Stage of phylogenetic studies (1) Polyphyletic group of taxa, the so-called ‘cetrarioid lichens', which has been delimited according to the gross morphology (Elix, 1993; Kärnefelt et al., 1992; Randlane & Saag, 1993; Randlane et al., 1997), currently includes 149 species from 25 genera. The monophyletic cetrarioid core group, defined by the phylogenetic analyses (Nelsen et al., 2011; Thell et al., 2009), includes 101 species from 17 genera, Ahtiana, Allocetraria, Arctocetraria, Cetraria, Cetrariella, Cetreliopsis, Dactylina, Esslingeriana, Flavocetraria, Kaernefeltia, Masonhalea, Melanelia, Nephromopsis, Tuckermanella, Tuckermannopsis, Usnocetraria, and Vulpicida. In the future, the confusion would be minimized if the phrase ‘cetrarioid lichens’ were to be used to refer to these genera only. The remaining eight genera (Asahinea, Bryocaulon, Cetrelia, Coelopogon, Cornicularia, Himantormia, Parmotrema, and Platismatia), which had earlier also been denoted as ‘cetrarioids’, belong phylogenetically either to the parmelioid core group (e.g. Cetrelia and Parmotrema) or to other, non-parmelioid groups with uncertain affinities within Parmeliaceae (Amo de Paz et al., 2011; Crespo et al., 2007). (2) 6 species formally accepted in the cetrarioid core group are known only by the original description or have only been superficially examined, meaning that these names could be synonyms of other species or these taxa may belong to other genera, i.e. drop out of the cetrarioid core group. These taxa are: Cetraria dermatoidea, C. nova-zealandiae, C. peruviana, C. subscutata, C. xizangensis, and Nephromopsis hengduanensis. (3) 9 species have currently a generic position which is not satisfactory according to molecular phylogenetic analyses (Nelsen et al., 2011; Thell et al., 2009), still, they have not been converted to any other genus because it is not convincingly clear where they belong. These taxa are: Ahtiana aurescens, A. pallidula, Cetraria annae, C. obtusata, C. sepincola, C. subalpina, Flavocetraria minuscula, Nephromopsis ornata, and Tuckermannopsis platyphylla. (4) For 29 species from the cetrarioid core group, DNA has not yet been studied and phylogenetic analyses performed. This means that the generic position of these taxa has not been confirmed and may, theoretically, change in future. The list of such taxa can be obtained from the digital checklist (http://esamba.bo.bg.ut.ee/checklist/cetrarioid), by performing a search in the field ‘Phylogenetic status of accepted taxa’, when choosing the option ‘cetrarioid core, DNA not studied’. (5) Some cetrariod genera, e.g. Melanelia, Nephromopsis and Tuckermannopsis, have gone through considerable changes concerning their delimitation. For example, genus Melanelia contained 37 species when described (Esslinger, 1978); after separating Melanelixia O. Blanco, A. Crespo, Divakar, Essl., D. Hawksw. & Lumbsch, Melanohalea O. Blanco, A. Crespo, Divakar, Essl., D. Hawksw. & Lumbsch (Blanco et al., 2004), Emodomelanelia Divakar & A. Crespo (Crespo et al., 2010) and Montanelia Divakar, A. Crespo, Wedin & Essl. (Divakar et al., 2012), all of which appear as members of the parmelioid core group, Melanelia s.s. includes 4 species that belong to the cetrarioid core group. The genus Cetraria, formally containing 23 species altogether, still needs further studies – 5 included species are poorly known, 4 species require revison of the generic position and 3 (Cetraria nepalensis, Cetraria rassadinae and C. steppae) of the 14 accepted species lack DNA studies.
