Estimating the Phanerozoic history of the Ascomycota lineages: combining fossil and molecular data.
The phylum Ascomycota is by far the largest group in the fungal kingdom. Ecologically important mutualistic associations such as mycorrhizae and lichens have evolved in this group, which are regardedExpand

Lichen Guilds Share Related Cyanobacterial Symbionts
Lichen symbioses represent a major way of life among the Fungi. Almost one-fifth of all known fungal species are lichenized, and about 1500 species of lichens contain cyanobacterial photobionts, mostExpand

Cyanobacteria produce a high variety of hepatotoxic peptides in lichen symbiosis
Lichens are symbiotic associations between fungi and photosynthetic algae or cyanobacteria. Microcystins are potent toxins that are responsible for the poisoning of both humans and animals. TheseExpand

Discovery of Rare and Highly Toxic Microcystins from Lichen-Associated Cyanobacterium Nostoc sp. Strain IO-102-I
ABSTRACT The production of hepatotoxic cyclic heptapeptides, microcystins, is almost exclusively reported from planktonic cyanobacteria. Here we show that a terrestrial cyanobacterium Nostoc sp.Expand

Cyanobiont specificity in some Nostoc‐containing lichens and in a Peltigera aphthosa photosymbiodeme
The cyanobacterial symbionts in some Nostoc-containing lichens were investigated using the nucleotide sequence of the highly variable cyanobacterial tRNALeu (UAA) intron. When comparing differentExpand

Spatial patterns of photobiont diversity in some Nostoc-containing lichens
Patterns of photobiont diversity were examined in some Nostoc-containing lichens using the nucleotide sequence of the cyanobacterial tRNALeu (UAA) intron. Lichen specimens collected in northwesternExpand

Amber fossils of sooty moulds
Sooty moulds are saprophytic ascomycetes with brown hyphae, often forming extensive subicula on living plant surfaces. These fungi growon plant exudates and honeydewsecreted by sap sucking insectsExpand
