Contributions to an epiphytic lichen flora of northwest North America: I. Eight new species from British Columbia inland rain forests

• Recent surveys of the inland rain forests of British Columbia and adjacentregions have brought to light an unexpectedly rich epiphytic lichen flora, including severalspecies apparently new to science. In the first of a series of papers, we describe eight speciesdiscovered during these surveys as new: Absconditella amabilis T. Sprib. (Ostropales),Bacidina contecta S. Ekman & T. Sprib., Biatora aureolepra T. Sprib. & Tønsberg, Biatoraligni-mollis T. Sprib. & Printzen (all Lecanorales), Collema coniophilum Goward(Peltigerales), Pertusaria diluta C. Bjo¨rk, G. Thor & T. Wheeler (Pertusariales), Schaereriabrunnea C. Bjo¨rk, T. Sprib. & T. Wheeler (Ostropomycetidae incertae sedis) andScoliciosporum abietinum T. Sprib. (Lecanorales). We also call attention to a ninth species,Bacidina sp. A, a poorly known and possibly undescribed colonizer of moribundcyanolichens. A majority of the above species appear to be confined to old-growth forests,while two (Biatora ligni-mollis and Schaereria brunnea) are currently known only from‘‘antique’’ forests older than about 500 years. Many additional undescribed epiphyticlichens are known from inland rain forests, underscoring the need for further baselinebiodiversity research in light of its ongoing disappearance as a result of resource extraction.In addition to the eight new species, we report Absconditella celata as new to NorthAmerica, Absconditella lignicola as new to Canada and Montana, Bacidina chloroticula asnew to British Columbia and Gyalideopsis piceicola as new to Montana.
