This study aims to clarify the systematics and phylogeny of Entyloma on Eryngium (Apiaceae) with molecular and morphological data. Eleven species from Eryngium are discussed herein. Copyright 2014 by The Mycological Society of America. Four of them are described as new taxa: E. carmeli sp. nov. on Eryngium falcatum, E. eryngii-cretici sp. nov. on Eryngium creticum, E. eryngii-maritimi sp. nov. on Eryngium maritimum and E. ho-chunkii sp. nov. on Eryngium yuccifolium. Analysis of the internal transcribed spacer (ITS) region of rDNA is presented and supports the polyphyly of Entyloma on Eryngium. Key words: Entylomataceae, host diversity, phytopathogen, smut fungi, taxonomy INTRODUCTION Entyloma de Bary comprises more than 160 species of smut fungi that are found on all continents except Antarctica (Vánky 2011). It is characterized by the formation of sori embedded in the tissue of the vegetative parts of dicotyledonous plants, which look like dense white spots or rarely pustules and galls. The characteristic features of this genus include mostly hyaline, solitary or crowded teliospores, which germinate with Tilletia-like basidia, simple host-parasite interaction apparatus and simple septal pores with two membrane cups (de Bary 1874, Bauer et al. 1997, Vánky 2011). Due to minimal morphology and limited taxonomically valuable characters, the systematics of this group is dependent on host taxonomy. More than 70 Entyloma species are found on Asteraceae and more than 10 on each of Apiaceae, Papaveraceae, Ranunculaceae and Scrophulariaceae (Begerow et al. 2002, Vanky 2011). Almost half of the species parasitizing umbellifers (Apiaceae) have been described on Eryngium L. hosts. The first species from this group was E. eryngii on Eryngium campestre L., described as Physoderma eryngii Corda (Corda 1839) and transferred to the genus Entyloma when it was created by de Bary (1874). Additional species were described from North Africa; they are E. eryngii-dichotomi Maire on Eryngium dichotomum Desf. (Maire 1917), E. eryngii-tricuspidati Maire on Eryngium tricuspidatum L. (Maire 1919) and E. maroccanum Maire on Eryngium maroccanum Pitard (Maire 1937), from Europe; they are E. eryngii-alpini Vánky on Eryngium alpinum L. (Vánky 2009) and E. eryngii-plani Cif. on Eryngium planum L. (Ciferri 1924). Entyloma argentinense Speg. on Eryngium nudicaule Lam. was described from South America (Spegazzini 1925). Eryngium is a large genus in subfamily Saniculoideae with approximately 250 species distributed worldwide (Wollf 1913, Wörz 2005). Taxonomically Eryngium is divided into two subgenera: Monocotyloidea for species from the Americas and Eryngium for species from Eurasia. Molecular phylogenetic studies support this infrageneric classification and reveal three strongly supported additional clades within Monocotyloidea, the so-called “South American species”, “Mexican” and “Eastern USA” (Calviño et al. 2008, 2010). Species of Entyloma have been reported on a number of members of subgenus Eryngium and on species from the “South American” clade of Monocotyloidea (Vánky 2009, 2011). Of note, no Entyloma species have been reported on “Mexican” and “Eastern USA” Eryngium species. Moreover, there are only several records of Entyloma on North American Eryngium aquaticum L. (Anonymous 1960), Eryngium yuccifolium Michx. (Clinton 1902, Gilman and Archer 1929, Green 1942, Fischer 1953) and on South American Eryngium nudicaule (Spegazzini 1925) from the “South American” clade, which most likely is due to incomplete sampling. In the most recent treatment of Entyloma on Eryngium, Vánky (2009) assumed that the radiation and speciation in this group was high and that each Eryngium species possesses its own Entyloma parasite. Taking into account this hypothesis, several records from different parts of the world do not correspond to any known Entyloma species. Most were reported as E. eryngii. Specimens have been reported on Eryngium aquaticum (Anonymous 1960) and Eryngium yuccifolium (Gilman and Archer 1929, Greene 1942, Fischer 1953, Zundel 1953) from North America, on Eryngium amethystinum L. from Slovenia (Voss 1889–1892), on Eryngium macrocalyx Schrenk from Kazakhstan and Uzbekistan (Ramazanova et al. 1987), and on Eryngium maritimum L. from France and Scotland (Ainsworth and Sampson 1950, Viennot-Bourgin 1956). Reports also exist of E. eryngii-tricuspidati on Eryngium creticumWebb. from Greece and Israel (Rayss and Zwirn 1944, Pantidou 1973) and, as found recently by the lead author, on Eryngium falcatum Delar. from Israel. Therefore, a critical revision of this group is necessary. To date, only two species of Entyloma on Eryngium (i.e. E. eryngii on Eryngium campestre and E. eryngii-plani on Eryngium planum) have been used in molecular phylogenetic studies (Begerow et al. 2002). The aim of this study is to critically analyze known Entyloma species on Eryngium hosts based on morphological and molecular phylogenetic data using recent collections in the analysis where possible. This work includes an ITS phylogeny of some Entyloma on Eryngium with focus on the Israeli specimens on Eryngium creticum and Eryngium falcatum and describes four species that are proposed as new. An identification key is provided for Entyloma species on Eryngium. MATERIALS AND METHODS Specimen sampling and documentation.—Specimens in this study are summarized (TABLE I). Herbarium samples are deposited in BPI, DAOM, FT, G, HAI, K, KRAM, MICH, NY, WIS and WSP. Nomenclatural novelties are registered in MycoBank (Crous et al. 2004). The hologenetype concept follows the proposal of Chakrabarty (2010). Morphological examination.—Sorus and spore characteristics were studied with dried herbarium material. Specimens were examined by light microscopy (LM). The characters assessed included: (i) sorus characters—shape, size, color, position on the leaves (abaxial, adaxial, amphigenous); (ii) spore morphology—the average length of spores, the average width, spore wall thickness, thickness of the outer layer, thickness of the inner layer, character of spore wall—even or uneven, color of spore matrix, color of outer layer of the spore wall; (iii) anamorph (if present)—position on the leaves (abaxial, adaxial, amphigenous), color. Micrographs of sori were taken with a Discovery 20 stereo microscope and AxioCam digital camera (Carl Zeiss Microscopy, Thornwood, New York) imaging system or Carl Zeiss Stemi D 4 stereo microscope. For LM, small pieces of leaf tissue with sori were mounted in 90% lactic acid on a microscope slide, several drops of distilled water were added, the slide was heated to the boiling point and cooled. The softened sori were cut in long pieces and squashed with a lancet, covered, gently heated to boiling point to eliminate air bubbles and examined under a Carl Zeiss Axiostar and a Carl Zeiss Axioplan2 compound light microscope imaging system at 1000× magnification. LM photographs were taken with a Canon Power Shot G10 and an AxioCam digital camera. At least 50 spores were measured from each collection, and the variation is presented as a range, with extreme values given in parentheses. In the descriptions, mean and standard deviations (SD) were calculated from spores measured in all specimens and provided after the spore sizes. DNA extraction and sequencing.—The majority of sequences were obtained from GenBank with seven additional sequences generated for this analysis (TABLE I). Genomic DNA was isolated from sori removed from herbarium specimens and lysed in 1.5 mL tubes for 1 min with a FastPrep 24 (MP Biomedicals, Irvine, California.). Tubes were incubated in a water bath 5 h at 55 C, and DNA was extracted with DNeasy Plant Mini Kit (QIAGEN Inc., Valencia, California) following the manufacturer's instructions. All amplifications were performed in 20 mL aliquots on a GeneAmp 9700 thermal-cycler (Applied Biosystems, Foster City, California). ITS5 or ITS1 were used as the forward primer and ITS4 as the reverse primer (White et al. 1990). Standard cycling parameters with an annealing temperature of 57 C were used for amplification. PCR products were purified with ExoSAP-IT (USB, Cleveland, Ohio) according to the manufacturer's instructions and amplified with respective forward and reverse PCR primers with the BigDye 3.1 terminator kit (Applied Biosystems). Those products were sequenced on an ABI 3100 automated DNA sequencer. Phylogenetic analysis.—The chromatographic outputs were assembled and edited into consensus sequences with Sequencher 4.5 for Windows. The consensus sequences were aligned in MAFFT 6 (Katoh et al. 2002, Katoh and Toh 2008) under default settings. Ambiguously aligned regions were recorded with GBlocks 091.b (Castresana, 2000) and excluded from the analyses. MAXTREES were unlimited, branches of zero length and ambiguously aligned regions were excluded from the analyses. PAUP 40b10 (Swofford 2002) was used to conduct the parsimony analysis. Trees were inferred with the heuristic search options that were collapsed and all multiple parsimonious trees were saved. Descriptive tree statistics for parsimony (tree length [TL], consistency index [CI], retention index [RI], relative consistency index [RC] and homoplasy index [HI]) were calculated for trees generated under different optimality criteria. Bootstrap analysis (Hill and Bull 1993) was based on 1000 replications. Bayesian analysis using a Monte Carlo Markov chain (MCMC) technique was implemented in MrBayes 3.1.2 (Huelsenbek and Ronquist 2001, Ronquist and Huelsenbek 2003). Four MCMC chains were run simultaneously, starting from random trees, for 1 000 000 generations. Trees were sampled every 100th generation for a total of 10 000 trees. The first 2000 trees were discarded as burn-in of each analysis. Posterior probabilities (Rannala and Yang 1996) were determined from a majority-rule consensus tree generated with the remaining 8000 trees. This analysis was done four times, starting from different random trees to ensure that trees from the same tree space were being sampled during each analysis. Clades supported with a minimum of 95% Bayesian posterior probabilities are considered well supported. Trees were rooted with Entyloma atlanticum Massenot as in Begerow et al. (2002). RESULTS Morphology.—Morphological characters for Entyloma spp. on Eryngium are summarized (TABLE II). The main complication in taxonomic work with Entyloma is that it has few meaningful morphological characters that can be used in species delimitation. Therefore we chose 14 characters that can be easily accessed with light microscopy for evaluation of taxonomic utility. Spore size overlapped among all species with the exception of E. eryngii with larger spores and E. eryngii-maritimi with smaller spores. Spore wall thickness was a more useful criterion for species delimitation than spore length and width and varied 0.8– 1.5 µm in E. maroccanum to 2.5–7 µm in E. eryngii. Sorus color, size, position and structure were different in all species (TABLE II). Anamorphs were found on lesions of E. eryngii-plani, E. eryngii-alpini, E. maroccanum, E. carmeli and E. eryngii-tricuspidati and were most abundant on the latter species. We were unable to obtain specimens of E. argentinense and E. maroccanum; therefore, all of the information on those two species was taken from sources in the literature. Phylogenetic analysis.—The ITS dataset consisted of 36 ingroup and one outgroup taxa. The alignment was deposited in TreeBASE 14656 and contained 655 characters. Of those characters 477 were invariable, 82 variable but parsimony uninformative and 96 parsimony informative. The different runs of Bayesian and the MP analyses yielded consistent topologies. A representative tree generated from the Bayesian analysis is presented to illustrate the results (FIG 1). One clade (BP below 70, PP = 87) containing all species on Apiaceae (E. eryngii, E. carmeli, E. eryngii-plani, E. eryngii-cretici, E. magocsyanum Bubák) grouped together with other species on Asterids. Of note, E. calceolariae Lagerh., a parasite on Calceolaria L. (Calceolariaceae, Lamiales), also was clustered in the clade with the species on Apiaceae. Within this clade were isolates of E. eryngii (PP = 98%), E. carmeli (PP = 100%) and E. eryngii-cretici (PP = 100%). Moreover, E. eryngii-plani and E. carmeli were clustered together with E. magocsyanum from Tordylium cordatum Poir., forming three separate lineages. TAXONOMY Entyloma argentinense (Speg.)

Notes: The most striking character of E. carmeli is the dark brown, flat sori. This species differs from other Eurasian species of Entyloma on Eryngium section Plana by thicker spore walls. Of interest, the holotypes of E. carmeli and E. eryngii-cretici were found less than 100 m from each other, occupying different ecological niches (i.e. humid, shady forest for the former species and dry, rocky slopes for the latter species). Entyloma carmeli differs from E. eryngii-cretici by slightly larger spores (av. 13.5 vs. 12.0 µm) and thicker spore walls (1.5–4 vs. 1.5–2.5 µm). In addition, an outer spore layer of E. carmeli is yellowish brown and of E. eryngii-cretici is pale golden yellow. Entyloma eryngii (Corda) de Bary, Bot.

It differs from all the other species by the formation of pustulate, cracked, sometimes bullate sori, generally larger spores and thick, uneven spore walls. Specimens from Eryngium hosts were reported under this name over the past century. Thus, it was reported on Eryngium ampelostrathum from Slovenia (Voss 1889–1892), Eryngium aquaticum from Iowa (Anonymous 1960), Eryngium macrocalyx from Kazakhstan and Uzbekistan (Ramazanova et al. 1987) and on Eryngium yuccifolium from Iowa and Wisconsin (Clinton 1902, Gilman and Archer 1929, Greene 1942, Fischer 1953, Zundel 1953). All specimens on the latter host belong to a different species, E. ho-chunkii, described in this paper. It is not possible to determine whether other specimens belong to E. eryngii without morphological examination. Unfortunately we were not able to locate those collections in any of the major world herbaria. Nevertheless, in that the respective hosts of these taxa belong to different sections of Eryngium (i.e. Panniculata for E. aquaticum, Halobia for Eryngium macrocalyx), it is likely that those collections represent undescribed species of Entyloma. It should be noted that Entyloma on North American Sanicula L. species have been reported as E. eryngii (Fischer 1953, Ellett 1959). Entyloma saniculae Peck, another species complex, also occurs on Sanicula species (Savchenko et al. in prep). Therefore, all collections of Entyloma eryngii on Sanicula need reexamination. Entyloma eryngii-alpini Vánky, Mycotaxon 110:304 (2009); Fig. 2d–f Sori in leaves forming roundish or polyangular, amphigenous, flat, gregarious spots, initially yellowish white and later yellowish brown, 0.2–2 mm diam or larger when confluent. Anamorph rarely present on the abaxial side of the leaves, not abundant, white.

Bolay, G 00111418. Notes: Entyloma eryngii-alpini differs from E. eryngii, the species to which it was first attributed by Servazzi (1950), in sorus and spore morphology. There are subtle differences between E. eryngii-alpini and another European species, E. eryngii-plani, in the color of young sori, which are yellowish white in the former species and greenish yellow in the latter. Another difference is the position of anamorph, which is amphigenous in E. eryngii-alpini and adaxial in E. eryngii-plani. Furthermore, Eryngium alpinum and Eryngium planum belong to different sections of Eryngium and were in different clades in the phylogentic analysis by Calviño et al. (2008).

Notes: Entyloma eryngii-cretici differs from Entyloma eryngii in sorus and spore morphology. It differs from all of the other species with hosts belonging to section Plana—E. carmeli, E. eryngii-dichotomi, E. eryngii-plani, E. eryngii-tricuspidati—by the absence of anamorph, from E. eryngii-dichotomi by thicker spore walls, 1.5–2.5(3) µm vs 1–1.5 µm, and from E. carmeli by the color of sori. In addition, species from section Plana for which sequences were available—E. carmeli, E. eryngii-cretici, E. eryngii-plani—did not form a monophyletic group in the phylogenetic analysis (FIG 1). Thus far, Entyloma on Eryngium creticum have been reported from Israel (Rays and Zwirn 1944, Savchenko et al. 2010) as E. eryngii or Entyloma sp. and from Greece (Pantidou 1973) as E. eryngii. This smut is probably widespread in the eastern Mediterranean but is overlooked. Entyloma eryngii-dichotomi Maire, Bull. Soc. Hist. Nat. Afr.

Wróblewski, BPI 175293 (as E. eryngii). Notes: Entyloma eryngii-plani differs from E. eryngii in having smaller spores, thinner spore walls and flat sori. It is similar to E. eryngii-cretici but has a slightly different color of spore matrix and an adaxial anamorph, while the latter species has no known anamorph. Furthermore, in the phylogenetic analysis, the sequence of E. eryngii-plani was in a different lineage from E. carmeli and E. eryngii-cretici, another species on hosts from section Plana. Entyloma eryngii-plani was reported from Germany to Siberia and is likely to have a wide distribution in temperate regions of Europe and Asia. Entyloma eryngii-tricuspidati Maire, Bull. Soc. Hist.

Notes: Maire (1919) and Vánky (2009) noted that Entyloma eryngii-tricuspidati differs from E. eryngii-dichotomi by the absence of an anamorphic stage. However, there is also a consistent difference in the spore wall thickness, which is 2–2.5 µm in E. eryngiitricuspidati and 1–2 µm in E. eryngii-dichotomi. So far Entyloma eryngii-tricuspidati is known only from Algeria. Entyloma ho-chunkii Savchenko, Carris, Castl., Heluta, Wasser & Nevo, sp. nov.

Notes: This smut was reported first from Iowa by Clinton (1902) as E. eryngii, and at that time it was the only known Entyloma species on Eryngium. Later H.C. Green (1942) collected several specimens in Wisconsin and, following Clinton's species concept, attributed them to the European species E. eryngii. However, Entyloma ho-chunkii is the only Entyloma species found on North American Eryngium hosts. In addition to a different geographic distribution, it differs from all of the other species by linear, not circular or polygonal, sori, smaller spores and host belonging to a different section of the genus. Entyloma ho-chunkii looks similar to E. eryngii-maritimi in terms of the small, hyaline spores. Nevertheless, the spores of the latter are smaller (av. 7.6 × 8.3 vs. 9.6 × 10.5), with an uneven spore wall thickness, while the spore walls of E. ho-chunkii are consistently uniform in thickness.

Entyloma sp. on Eryngium macrocalyx Sori in leaves forming circular or polyangular, amphigenous, flat, thickened, yellowish brown, pinkish purple spots, 0.5–2 mm diam. Anamorph absent. Spores crowded, densely packed, globose, subglobose, ovoid, subpolyhedrally irregular, 15 × (7)9–18(21) µm diam. Spore wall two-layered, uneven, 1–2(4) µm thick. Outer layer yellowish, brown, smooth. Host range: Eryngium macrocalyx section Halobia. Notes: This smut has been reported as E. eryngii from Kazakhstan and Uzbekistan (Ramazanova et al. 1987). We were not able to obtain specimens for microscopic examination, but according to the original description it possesses some clear differences from all known species of Entyloma on Eryngium: It differs from E. eryngii by the morphology of sori and thinner spore walls, has larger spores than any of the remaining species of Entyloma on Eryngium and has a unique sorus color. Therefore it is treated here as a separate taxon without formal description. DISCUSSION Macro- and micromorphological study, combined with phylogenetic analyses, revealed a greater amount of diversity among Entyloma species on Eryngium than was reflected in the existing treatments (Vánky 2009, 2011). Eleven species now are recognized: E. argentinense and E. ho-chunkii from the Americas; E. carmeli, E. eryngii, E. eryngiialpini, E. eryngii-cretici, E. eryngii-maritimi and E. eryngii-plani from Eurasia; E. eryngiidichotomi, E. eryngii-tricuspidati and E. maroccanum from Africa. The speciation of Entyloma on Eryngium is clearly related to the evolutionary relationships of the hosts. Indeed, high speciation is not rare among smut fungi and was reported for Microbotryum Lév. (Freeman et al. 2002; Lutz et al. 2005, 2008; le Gac et al. 2007; Denchev et al. 2008; Devier et al. 2010), Antherospora R. Bauer et al. (Bauer et al. 2008, Piątek et al. 2013), Tilletia Syd. & P. Syd. (Castlebury and Carris 1999; Carris et al. 2007) and Anthracoidea Bref. (Savchenko et al. 2013). It might seem surprising that more than half of the Entyloma species recognized occur on members of section Plana, but it is noteworthy that this section was found to be heterogeneous (Calviño et al. 2008, 2010). Our phylogenetic analyses demonstrate that all Entyloma species on Apiaceae clustered within the Apiaceae clade, sharing a common ancestor with other groups of Entyloma on Asterids. The distribution in the phylogenetic topology does not suggest monophyly for the species on Eryngium, in that E. magocsyanum from Tordylium Tourn. ex L., another genus of Apiaceae, also occurred within this clade. Eryngium and Todylium belong to different subfamilies and it was proved by molecular phylogeny (Downie et al. 2000). Therefore, the possible close relationship between E. magocsyanum and Entyloma on Eryngium may be explained by a recent host shift. Moreover, E. calceolariae clusters in the same subgroup. In this case, the host is not a member of Apiaceae or a closely related family and instead belongs to Lamiales. Such a distribution could be explained by host jumps, which are not rare in smut fungi (Begerow et al. 2002, 2004). Two species from Israel, E. carmeli and E. eryngii-cretici, are not closely related, and there is a 12 bp difference in the ITS nucleotide sequences between the specimens infecting Eryngium falcatum and Eryngium creticum. Furthermore, according to our data, E. carmeli is possibly more closely related to E. magocsyanum and E. eryngii-plani than to E. eryngiicretici. Even so, their hosts belong to the same section and both species grow in the same region. Hence, it does not appear that geographical isolation played a role in the evolutionary history of these species. However, our observations revealed that they grow in different habitats and therefore ecological sympatric speciation may have occurred in this case. In conclusion, our data reveal a strong correlation of these parasites with their respective hosts. We accept seven described species of Entyloma on Eryngium and describe four new species based on molecular and/or morphological data and hosts from different sections. Our results provide an additional resource for accurate species identification. The fact that there are only two species from the Americas where a second center of speciation of Eryngium occured (Calviño et al. 2008, 2010) makes it clear that additional collections in that region might lead to recognition of greater diversity within the genus.
