  • 21 January 1999
TLDR
This is a taxonomic revision of the corticolous and lignicolous taxa of the genera Bacidia and Bacidina in the continental United States and Canada and describes nine new taxa, including two newly described species.
Most species of Lepraria and Leproloma form a monophyletic group closely related to Stereocaulon
TLDR
The phylogenetic position of members of the entirely asexually reproducing lichen-forming genera Lepraria and Leproloma was investigated using sequence data from the ITS1-5.8S-ITS2 and small subunit (SSU) nuclear ribosomal DNA and results indicate that most species currently referred to Leprechauns form a single monophyletic group.
Extended phylogeny and a revised generic classification of the Pannariaceae (Peltigerales, Ascomycota)
TLDR
A revised generic classification for the Pannariaceae is proposed, accepting 30 genera, based on the phylogeny, previously published phylogenies, as well as available morphological and chemical data.
High performance thin layer chromatography (HPTLC), an improved technique for screening lichen substances.

Molecular systematics and character evolution in the lichen family Ramalinaceae (Ascomycota: Lecanorales)
The Ramalinaceae is the fourth-largest family of lichenized ascomycetes with 42 genera and 913 species exhibiting considerable morphological variation. Historically, generic boundaries in the Ramal
PCR OPTIMIZATION AND TROUBLESHOOTING, WITH SPECIAL REFERENCE TO THE AMPLIFICATION OF RIBOSOMAL DNA IN LICHENIZED FUNGI
TLDR
Nested PCR is described and a protocol that has been shown to work well for the amplification of ribosomal genes in ascomycetes is described, claiming that DNA extracts of lichenized fungi, contrary to many other organism groups, are often contaminated by other fungi.
Disintegration of the Micareaceae (lichenized Ascomycota): a molecular phylogeny based on mitochondrial rDNA sequences.
TLDR
It is suggested that the Micareaceae is reduced to synonymy with the Pilocarpaceae, which also includes the Ectolechiaceae, and that Micarea may have to be divided into a series of smaller genera in the future.
Phylogeography of Cavernularia hultenii: evidence of slow genetic drift in a widely disjunct lichen
TLDR
Mismatch distributions indicate exponential population growth, probably during postglacial invasion of C. hultenii into formerly glaciated areas of western North America and the presence of one southern and at least one northern glacial refugium in South Central Alaska is inferred.
Molecular phylogeny of the Bacidiaceae (Lecanorales, lichenized Ascomycota)
TLDR
The phylogeny of the family Bacidiaceae was investigated using 65 nuclear ITS1-5,8S-ITS2 ribosomal DNA sequences, which suggests that the Bacidia beckhausii and B. sabuletorum groups are unrelated to Bacidia s.
The limitations of ancestral state reconstruction and the evolution of the ascus in the Lecanorales (lichenized Ascomycota).
TLDR
This investigation explored the outcomes of a variety of methods for reconstructing discrete ancestral state in the ascus apex of the Lecanorales, a group containing the majority of lichen-forming ascomycetes, and designed a novel method for assessing the suitable number of discrete gamma categories which relies on the effect on phylogeny estimates rather than on likelihoods.
