Fig. 1. 50 in Parmotrema clavuliferum and P. reticulatum are independent species
Fig. 1. 50% majorityrule consensus tree of the molecular phylogenetic relationships in Parmotrema clavuliferum and P. reticulatum, based on 15,000 trees from the B/MCMC treesampling procedure and from the dataset of nu ITS and mt SSU sequences. Branches that were strongly supported in all three analyses (i.e., PP ≥ 0.95 in the B/MCMC analysis and ≥ 70% in both bootstrap values of the ML and MP) are indicated in solid bold line. Numbers on branches indicate bootstrap values of ML (left), MP (middle), and B/MCMC posterior probabilities (right).
Data from: Parmotrema internexum (Lecanorales: Parmeliaceae): an overlooked macrolichen in southeastern North America highlights the value of basic biodiversity research
Parmotrema internexum is shown to be a morphologically, chemically and phylogenetically distinct species whose occurrence in North America has been previously overlooked and largely based on misidentifications. Prior accounts of the species being similar to P. crinitum but differing in having an adnate thallus, few marginal cilia, and in producing norlobaridone in addition to the stictic acid complex, are confirmed. An extensive review of the taxon, including the use of the name P. internexum in the literature, is provided. Taxonomic treatments of P. crinitum and P. internexum are also provided and both species are illustrated.
Data from: The Parmotrema acid test: a look at species delineation in the P. perforatum group 40 y later
Parmotrema perforatum and its relatives form a morphologically distinctive group of species, most of which are common and endemic to eastern North America. Species delimitation in this ecologically important group was the subject of extensive inquiry before the advent of molecular systematics and computationally intensive niche modeling. As part of a large-scale lichen biodiversity inventory of the Mid-Atlantic Coastal Plain, we used ITS sequence data to examine the utility of characters (morphological, chemical, reproductive, ecological) in circumscribing four species in this group (P. hypoleucinum, P. hypotropum, P. perforatum, P. subrigidum). We found that P. hypoleucinum and P. subrigidum as currently circumscribed are monophyletic and the latter comprises two chemotypes differing in the presence or absence of norstictic acid in addition to alectoronic acid. The sequences of P. hypotropum and P. perforatum, which are chemically identical species and differ only in reproductive mode, were intermixed in a single, well-supported clade. The two chemotypes of P. subrigidum are partially allopatric and their sequences are > 99% identical. Nonetheless, niche modeling suggests they occupy significantly different ecological niches. These results provide a new perspective on much-debated questions on species circumscription in lichens and suggest new avenues for genetic, ecological and systematic research.
