The alectorioid lichens form a morphological group in Parmeliaceae the phylogenetic relationships<br />
of wich are still unclear; the concept we are using here includes Alectoria, Bryocaulon, Bryoria,<br />
Nodobryoria, Oropogon, Pseudephebe and Sulcaria. The species are fruticose, from erect to pendent<br />
and with cylindrical thalli, a hard cortex, and a lax medulla. Most species in the group usually lack sexual<br />
structures and morphological variability is scarce. Moreover, in some groups, as in Bryoria, species<br />
have high intraspecific variability and there are not uncomonly cases where one single specimen shows<br />
intermediate characters of several species. We are focusing this investigation in the section Implexae<br />
of this genus including Bryoria chalybeiformis, B. capillaris, B. glabra, B. implexa, B. fuscescens, B.<br />
lanestris and B. subcana.<br />
In this contribution we present a multigenic phylogenetic reconstruction using ITS, LSU<br />
nrDNA, SSU mtDNA, and single copy protein coding gene MCM7 of more than 50 species.<br />
Preliminary results reveal: (a) the alectorioid lichens are split into two independent lineages, (b)<br />
the genera are monophyletic, and (c) within Bryoria sect Implexae the most common European<br />
taxa are conspecific.<br />
