Gut morphology and rate of digesta passage through the gut in captive giant white-tailed rats (Uromys caudimaculatus) were investigated. Rate of passage was measured using a solute marker (Co-EDTA), a marker of large particles (Cr-mordanted plant cell walls) and spores of the ectomycorrhizal fungus Pisolithus spp. The mean retention time (MRT) of fungal spores in the whole gut (48.4 ± 6.0 h), was long in comparison to that found in other rodents of similar body mass and was intermediate to MRT of the solute marker (45.4 ± 8.8 h) and the large particle marker (55.5 ± 7.2 h). Thus, retention of spores is likely to be little affected by being free or attached to pieces of ingested fruiting bodies. The stomach is unilocular and hemiglandular and contains a large fundic diverticulum lined entirely by non-glandular squamous epithelium. The significantly longer MRT for the large particle marker than the solute marker suggests that some selective retention of particles takes place, probably in the fundic diverticulum of the stomach. We suggest that the large fundic diverticulum may function in storage and possibly increased digestive efficiency of starchy food items, and in retaining spores, especially when still attached to fruiting bodies.

The Neyveli lignite is one of the largest brown coal field of India, Cuddalore district of Tamil Nadu. The lignite it is one of tertiary formation found in the Neyveli, So far many mega and micro fossils reported from this formation. The Neyveli lignite well preserved and recognizable entities are mainly woody and non-woody tissues of different angiosperm plants, spore and pollen, cuticles of leaves, resins, fungal spores and fungal fruiting bodies. The present study is about the charcoalified angiospermic wood is identified as Hopenium pondicherriensis (Dipterocarpaceae). This is a first report of Hopenium pondicherriensis from the Neyveli formation.

AbstractThe dry-rot fungus Serpula lacrymans causes enormous structural damage by decaying construction timber thereby resulting in tremendous financial loss. Dry-rot fungi decompose cellulose and hemicellulose and, if the wood remains wet, are often accompanied by a succession of bacteria and other fungi. Bacterial-fungal interactions have considerable impact on all interaction partners ranging from antagonistic to beneficial relationships. However, little is known about possible interaction partners of S. lacrymans. Here we show that S. lacrymans has many co-existing, mainly Gram-positive bacteria. By investigating differences in the bacterial community associated with fruiting bodies, mycelia and rhizomorphs, we provide evidence of preferential colonization of S. lacrymans tissues by certain bacterial phyla. Bacteria isolated from fruiting bodies and mycelia were dominated by Firmicutes, while bacteria isolated from rhizomorphs were dominated by Proteobacteria. Actinobacteria and Bacteroidetes were found in lower abundances. In situ fluorescence hybridization (FISH) analysis revealed that bacteria were not present biofilm-like, but occurred as independent cells, sometimes also attached to fungal spores. In co-culture, single bacterial isolates caused growth inhibition of S. lacrymans and vice versa. Additionally, certain bacteria induced pigment production in the fungus. Our results provide first insights for a better understanding of the holobiont S. lacrymans and give hints that bacteria are able to influence the behavior, e.g. growth and secondary metabolite production, of S. lacrymans in culture.ImportanceSerpula lacrymans is a very effective dry-rot causing fungus, specialized in degradation of coniferous timber in houses. The initial colonization is favored by water damage, and after establishment, the fungus starts to destruct cellulose and hemicellulose. It is among the most feared wood-rotting fungi in the built environment as the remediation of S. lacrymans damaged buildings is expensive and tedious. After improper renovation, the possibility of a recolonization by S. lacrymans is likely. As bacteria influence fungal establishment on wood, the need to investigate the bacterial community associated with S. lacrymans is apparent. The significance of our research is in identifying and characterizing bacteria associated with S. lacrymans. This will allow the assessment of their influence on fungal life style, leading to a broader understanding of the properties that make S. lacrymans so extraordinarily aggressive at decaying wood compared to other indoor wood destroyers.
