The enigmatic hyphomycete Torula sensu Caspary revisited
No full textAbout 130 years ago Robert Caspary described fossil fungi resembling the extant anamorphic genus Torula Persoon (Ascomycota,Pezizomycotina) from two pieces of Eocene Baltic amber. 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.

Noninvasive ¹³C-octanoic acid breath test shows delayed gastric emptying in patients with amyotrophic lateral sclerosis
No full textAmyotrophic lateral sclerosis (ALS) is a fatal neurodegenerative disorder characterized by progressive loss of motor neurons. However, ALS has been recognized to also involve non-motor systems. Subclinical involvement of the autonomic system in ALS has been described. The recently developed C-13-octanoic acid breath test allows the noninvasive measurement of gastric emptying. With this new technique we investigated 18 patients with ALS and 14 healthy volunteers. None of the patients had diabetes mellitus or other disorders known to cause autonomic dysfunction. The participants received a solid standard test meal labeled with C-13-octanoic acid. Breath samples were taken at 15-min intervals for 5 h and were analyzed for (CO2)-C-13 by isotope selective nondispersive infrared spectrometry. Gastric emptying peak time (t(peak)) and emptying half time (t(1/2)) were determined. All healthy volunteers displayed normal gastric emptying with a mean emptying t(1/2) of 138 +/- 34 (range 68-172) min. Gastric emptying was delayed (t(1/2) > 160 min) in 15 of 18 patients with ALS. Emptying t(1/2) in ALS patients was 218 +/- 48 (range 126-278) min (p < 0.001). These results are compatible with autonomic involvement in patients with ALS, causing delayed gastric emptying of solids and encouraging the theory that ALS is a multisystem disease rather than a disease of the motor neurons only
Caspary’s fungi from Baltic amber : historic specimens and new evidence
No full textAmber is a valuable source of Mesozoic and Cenozoic fossil fungi. The earliest amber-preserved fungi were described in the nineteenth and early twentieth centuries from Eocene Baltic amber. In 1907, Richard Klebs summarized the legacy of Robert Caspary based on his specimens, research notes and publications. This treatise contains descriptions and illustrations of 13 morphologies of fossil fungi which have not been investigated since. We managed to locate six of Caspary’s amber specimens and imaged and re-investigated the fossil fungi within. We provide amended descriptions of these six specimens, select new specimens from historic and recent collections which are probably conspecific with five fossils that appear to have been lost, and finally also describe and evaluate five newly found fossil fungi from Baltic amber. The fungi belong to the phylum Ascomycota (Subkingdom Dikarya). Only two of Caspary’s fungi can be confidently assigned to modern genera, Metacapnodium (Metacapnodiaceae) and Calicium (Caliciaceae). The new combination Calicium succini (Caspary) Rikkinen & A. R. Schmidt is made. The fossils originally placed in Acremonium, Cetraria, Gonatobotrys, Ramularia, Stilbum and Torula cannot be assigned to these genera, and should not be used as minimum age constrains for the respective lineages.Peer reviewe
The sporophyte of the Paleogene liverwort Frullania varians Caspary
No full textWe document the sporophyte of the extinct Frullania varians based on an inclusion in Late Oligocene Bitterfeld amber from Germany. The sporophyte consists of a short, ca. 45 µm thick seta that exceeds the perianth only slightly; the elongate-ovate, acute valves of the opened capsule are about 225 µm long, curved backwards and consist of an epidermal and an internal layer. Cell walls of both layers possess nodulose trigones. Several trumpet-shaped, unispiral elaters are fixed to the upper third of the internal valve layer. They have a length of ca. 150 µm and a diameter of 15–18 µm. A subglobose structure of 19 µm diameter is interpreted as a degraded spore. Fossil elaters and spores as well as capsule wall details of Frullaniaceae are described for the first time.doi:10.1002/mmng.20120000
