Despite being among the earliest fungi recognized from amber, these microfossils have received virtually no attention for the past 100 years. Our recent findings of similar fungal inclusions from Baltic and Bitterfeld amber have revealed that these fungi constituted an abundant, but poorly understood component of these Paleogene amber forests. Here we elucidate the morphology and growth mode of these enigmatic fungi and show that they are clearly distinguished from the moniliform hyphae of capnodialean sooty moulds (Ascomycota, Capnodiales), that they also do not correspond with the extant genus Torula, and cannot with confidence be assigned to any extant genus of dematiaceous hyphomycetes. The life cycle of the fungi involved transitions from vegetative hyphae to conidial states producing non-randomly disarticulating chains of multi-cellular phragmoconidia. We provide an emended description of these fungi and suggest a new fossil genus Casparyotorula that comprises three anamorphic species, Casparyotorula globulifera (Caspary) comb. nov., Casparyotoruia heteromorpha (Caspary) comb. nov., and Caspcnyotorula arnoldii sp. nov.

Various physical and chemical techniques have been used to identify and profile different plant resins and have then been applied to fossilized resins (ambers), to try to detect their parent plant affinities and understand the process of polymerization, with varying levels of success. Here we focus on resins produced from today's most resinous conifer family, the Araucariaceae, which are thought to be the parent plants of some of the Southern Hemisphere's fossil resin deposits. Fourier transform infrared (FTIR) spectra of the resins of closely related Araucariaceae species were examined to test whether they could be distinguished at genus and species level and whether the results could then be used to infer the parent plant of a New Zealand amber. The resin FTIR spectra are distinguishable from each other, and the three Araucaria species sampled produced similar FTIR spectra, to which Wollemia resin is most similar. Interspecific variability of the FTIR spectra is greatest in the three Agathis species tested. The New Zealand amber sample is similar in key shared features with the resin samples, but it does differ from the extant resin samples in key distinguishing features, nonetheless it is most similar to the resin of Agathis australis in this dataset. However on comparison with previously published FTIR spectra of similar aged amber and older (Eocene) resinites both found in coals from New Zealand and fresh Agathis australis resin, our amber has some features that imply a relatively immature resin, which was not expected from an amber of the Miocene age."],["dc.identifier.doi","10.7717/peerj.1067"],["dc.identifier.pmid","26157631"],["dc.identifier.purl","https://resolver.sub.uni-goettingen.de/purl?gs-1/13603"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/15275"],["dc.language.iso","en"],["dc.notes.intern","Merged from goescholar"],["dc.notes.status","final"],["dc.relation.eissn","2167-8359"],["dc.rights","CC BY 4.0"],["dc.rights.uri","https://creativecommons.org/licenses/by/4.0/"],["dc.title","Species-level determination of closely related araucarian resins using FTIR spectroscopy and its implications for the provenance of New Zealand amber"],["dc.type","journal_article"],["dc.type.internalPublication","unknown"],["dc.type.version","published_version"],["dspace.entity.type","Publication"]]

Bieb., Viscaceae) are hemiparasites with complex roles in nature. They are one of the most severe pests in northern hemisphere conifer forests, but they also enhance the structural complexity and species diversity of the forests. Here, we describe the first pre-Miocene macrofossils of dwarf mistletoes. The fossils from Eocene Baltic amber provide new insights into the morphological evolution of the Arceuthobium lineage and its paleobiogeography. METHODS: The amber inclusions were investigated with light microscopy and compared with extant Viscaceae and to historic descriptions of lost Baltic amber fossils with affinities to Viscaceae. KEY RESULTS: Six fossil species of the A rceuthobium lineage, A. johnianum comb. nov.,A. mengeanum comb. nov., A. conwentzii sp. nov., A. groehnii sp. nov., A. viscoides comb. nov. and A. obovatum sp. nov., occurred in source forests of Baltic amber, representing the oldest macrofossil evidence of dwarf mistletoes. They share morphological features of their bracts, internodes, fruits, and stomata with extant Arceuthobium. Differences from extant dwarf mistletoes, such as the perianth merosity, the nonfusion of squamate bracts and presence of oblanceolate expanded leaves, indicate their affiliation to an ancient lineage of the genus. CONCLUSIONS: The occurrence of six species of dwarf mistletoes in a single amber deposit suggests A rceuthobium was a keystone taxon of the Baltic amber source area. As in extant conifer forests, they probably influenced the structural complexity of the forest, not only leading to more open woodlands but also increasing species diversity, at least at a microhabitat scale."],["dc.identifier.doi","10.3732/ajb.1600390"],["dc.identifier.isi","000402016000009"],["dc.identifier.pmid","28533204"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/42621"],["dc.language.iso","en"],["dc.notes.status","final"],["dc.notes.submitter","PUB_WoS_Import"],["dc.relation.issn","1537-2197"],["dc.relation.issn","0002-9122"],["dc.title","Diverse early dwarf mistletoes (Arceuthobium), ecological keystones of the Eocene Baltic amber biota"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dspace.entity.type","Publication"]]
