(1998):
Phylogenetic relationships of some cetrarioid species in British Columbia with notes on Tuckermannopsis,
Folia Cryptogamica Estonica,
32: 113–122
Phylogenetic relationships of seven cetrarioid lichens – Ahtiana sphaerosporella, Esslingeriana idahoensis, Kaernefeltia
merrillii, Tuckermannopsis americana, T. platyphylla, T. subalpina and Vulpicida canadensis – occurring in British Columbia are
analysed together with seven other cetrarioid species using parsimony analysis. The phylogenetic hypothesis based on ITS
sequences suggest that ascus characters cannot be used as characters to distinguish genera within cetrarioid lichens but
pycnoconidial …
