Abstract
The presence or absence of an iodine reactive ascus tip has been applied inconsistently in Hemiphacidiaceae. The genera Hemiphacidium (I-) and Sarcotrochila (I+) have been differentiated based on the reaction despite a high degree of morphological and ecological similarity, while in the genus Rhabdocline, the iodine reaction has been used to differentiate species and circumscribe subspecies. Molecular phylogenetic analyses indicate that currently recognized subspecies of R. weirii are non-monophyletic while those of R. pseudotsugae form distinct sister lineages. The polyphyly of R. weirii suggests that the presence or absence of an I+ ascus pore is not a good predictor of species circumscriptions. To de-emphasize the importance of the iodine reaction in classification within Hemiphacidiaceae and to promulgate a classification more consistent with relationships revealed by molecular phylogenetics, we propose that Hemiphacidium be synonymized under Sarcotrochila and that subspecies of Rhabdocline pseudotsugae and R. weirii be raised to species rank. The following new combinations are proposed: Sarcotrochila longispora, S. plana, S. convexa, Rhabdocline oblonga, R. obovata, and R. epiphylla.
