Geographic distribution of Sarcoporia polyspora and S-longitubulata sp nov.

DNA study of Sarcoporia polyspora (= Parmastomyces transmutans) revealed only negligible sequence differences between conifer-dwelling specimens with cartilaginous layer in the context from USA, Brazil, Europe, and Far East Asia, but a very different sequence from three resupinate and hardwood-bound collections without such a layer and with slightly narrower and pale brown spores from USA and Madeira Islands. This fungus, found also among historical USA collections of S. polyspora in the BPI herbarium, is described here as Sarcoporia longitubulata. The phylogenetic position of Sarcoporia is discussed.
