abstract = {Molecular phylogenies inferred from the nuclear small subunit rRNA gene (nuSSU), nuclear
large subunit rRNA gene D1/D2 region (nuLSU), and ITS-5.8S rRNA gene (ITS) indicated
that five cultures of the lichenized hyphomycete Dictyocatenulata alba isolated from Japan
form a monophyletic clade with high bootstrap support, and a close relationship to the
Ostropomycetidae (Lecanoromycetes, Pezizomycotina, Ascomycota). Insertion sequences
were found in the nuSSU of all isolates (e.g., nine insertions in the strain JCM 5358), some of
which were group I introns. Five new insertion positions were found among the D. alba
isolates. Using BLAST, none of the insertion sequences of D. alba were closely related to
those of fungi or other organisms deposited in public DNA databases. Insertion positions were
similar in some isolates, and two positions were common to all isolates. Although all
phylogenetic analyses based on nuSSU, nuLSU, and ITS revealed the monophyly of D. alba,
the isolates were divided into two (in the nuSSU tree) or three (in the nuLSU and ITS trees)
groups. Based on the phylogenetic analyses and the intron-exon structures, the five isolates
identified as D. alba belong to three cryptic species and therefore D. alba should be
considered a species complex. The very slow-growing, tough agar colonies of the isolates, the
occurrence of the species on both slightly lichenized and non-lichenized surfaces of trees, or
pebbles (rarely on soil), suggest that the members of the D. alba complex may be lichenized.
The photobiont was not clearly identified in this study.}
