Tryblidiopsis pinastri (Leotiomycetes, Rhytismatales) was described from Picea abies in Europe and was also thought to occur on North American Picea. However, previously published sequences of Picea foliar endophytes from Eastern Canada suggested the presence of at least two cryptic Tryblidiopsis species, distinct from T. pinastri and other known species. Our subsequent sampling of Tryblidiopsis ascomata from dead attached Picea glauca branches resulted in the collection of a putatively undescribed species previously isolated as a P. glauca endophyte. Morphological evidence combined with phylogenetic analyses based on nuclear ribosomal internal transcribed spacer (ITS) and large subunit ribosomal (LSU) DNA sequences support the distinctiveness of this species, described here as T. magnesii.
