“…Other studies confirmed the species status of previously synonymized taxa, e.g. Punctelia jeckeri (P. ulophylla, Crespo et al 2004b;Thell et al 2005) or Parmotrema pseudoreticulatum (Divakar et al 2005a). However, there are exceptions.…”

“…Cryptic lineages have been reported in various, unrelated groups of fungi, including the Cladia aggregata group (Parnmen 2011), the genus Letharia (Kroken and Taylor 2001), the Parmelina tiliacea aggr. , the Parmotrema reticulatum group (Divakar et al 2005a), and the Rhizoplaca melanophthalma complex (Leavitt et al 2011c). Further, there is evidence for the presence of cryptic lineages in tropical Porina spp.…”

Goodbye morphology? A paradigm shift in the delimitation of species in lichenized fungi

Accurate species delimitations are crucial for ecological and conservation studies, assessments of biotic diversity, and identifying factors driving diversification. Estimates suggest that the vast majority of fungal species are currently unknown. Although many undescribed fungal taxa are expected to be indentified within understudied groups and from underexplored areas, mounting evidence suggests a substantial number of unrecognized fungal species are likely hidden within traditional phenotypebased species in lichen-forming fungi. Molecular genetics has revolutionized our ability to assess traditional species concepts and provides additional tools for robust species delimitation. In general, lichens display few taxonomically usefully characters; therefore molecular data have gained great importance in delimiting fungal species in lichen symbioses. As a result, the taxonomic value of phenotypical characters is now much better understood, and in many cases previously overlooked characters have been identified supporting molecular-based species circumscriptions. Although in some cases molecular research has verified traditional hypotheses, most studies repeatedly show that our current interpretation of morphological and chemical characters is inadequate to accurately characterize diversity. Here we report on the role of molecular data in understanding species-level diversity in lichenized fungi by reviewing current literature, focusing primarily on Ascomycota. While finding and applying the appropriate character sets and analytical tools remains one of the greatest challenges to empirical species delimitation in lichen-forming fungi, the available literature indicates that the inclusion of molecular data in species circumscription is crucial to establish robust hypotheses of species boundaries in this important group of fungi.

“…For example, several cases have been detected in the Parmeliaceae, where the presence of cryptic species is not restricted to any particular mode of reproduction. Cryptic lineages have been reported in apotheciate taxa such as Parmelina quercina (Argüello & al., 2007), the isidiate Parmelia saxatilis (Crespo & al., 2002;Molina & al., 2004) and the sorediate Parmotrema reticulatum (Divakar & al., 2005b). It should be noted that, although available studies are unequivocal in revealing cryptic lineages within lichen morphospecies, the lack of molecular markers with greater resolution tends to limit studies in some groups of lichens.…”

ResumenCrespo, A. & Pérez-Ortega, S. 2009. Especies crípticas y pares de especies en líquenes: una discusión sobre la relación entre la filogenia molecular y los caracteres morfológicos. Anales Jard. Bot. Madrid 66S1: 71-81 (en inglés).Como en otras disciplinas, el impacto producido por la filogenia molecular en el conocimiento de los hongos liquenizados ha producido avances y cambios conceptuales importantes. Esto ha sido especialmente cierto en la sistemática y ha afectado de una manera muy notable en aspectos relacionados con la delimitación de las especies. En muchos casos los datos moleculares han verificado las hipótesis tradicionalmente aceptadas en relación con la definición y el reconocimiento de especies, pero en otros han producido conflictos con el concepto morfológico todavía en uso. Este trabajo trata de los recientes progresos en dos direcciones principales: (i) las especies crípticas, es decir, dos o más linajes independientes que exhiben o aparentan una morfología similar; y (ii) los pares de especies, que son especies con morfología similar pero que exhiben diferentes modos de reproducción. Ambos conceptos tienen en común la falta de correlación entre datos filogenéticos y morfológicos, al menos en lo que se refiere a los caracteres normalmente utilizados en la sistemática de líquenes. Hemos analizado la literatura disponible sobre especies crípticas y pares de especies, centrando los ejemplos preferentemente en la familia Parmeliaceae (Lecanoromycetes, Ascomycota). En los hongos liquenizados, los datos moleculares han demostrado reiteradamente la existencia de especies crípticas, pero los investigadores han sido a menudo muy prudentes a la hora de reconocer como tales los nuevos táxones que se vislumbran. De hecho, las investigaciones se han esforzado en la observación cuidadosa de caracteres morfológicos informativos o de caracteres ecológicos o geográficos; ello está proporcionando un buen apoyo para un sólido planteamiento biológico que va parejo al reconocimiento formal de las especies crípticas. Al contrario, en el caso de los pares de especies, raro es el par de especies, entre los estudiados, en que se haya podido confirmar que realmente se trata de linajes independientes. Por As with most disciplines in biology, molecular genetics has revolutionized our understanding of lichenized fungi. Nowhere has this been more true than in systematics, especially in the delimitation of species. In many cases, molecular research has verified long-standing hypotheses, but in others, results appear to conflict with existing morphological species concepts. This work reports on recent progress regarding two main issues: (i) cryptic species, i.e., two or more independent lineages exhibiting similar morphology; and (ii) species pairs, two species with similar morphology but exhibiting different reproductive modes. Both concepts have in common a lack of correlation between phylogenetic and morphological data, at least for characters normally used in lichen systematics. We review the available literature on...
