The adenyl cyclase and phosphodiesterase metabolizing adenosine 3',5'-cyclic monophosphate (cyclic AMP) were detected in mycelia of strains of Coprinus macrorhizus which form fruiting bodies, but not in those of strains which do not form fruiting bodies. The adenyl cyclase synthesized cyclic AMP from adenosine triphosphate. The phosphodiesterase degr[UNK]ded cyclic AMP to adenosine-5'-monophosp...

We have examined the stability of duplicated DNA sequences in the sexual phase of the life cycle of the basidiomycete fungus, Coprinus cinereus. We observed premeiotic de novo methylation in haploid nuclei containing either a triplication, a tandem duplication, or an ectopic duplication. Methylation changes were not observed in unique sequences. Repeated sequences underwent methylation changes ...

Coprinus comatus, also called chicken drumstick mushroom, is currently commercially available in China. Hot water and ethanolic extracts were prepared from cap and stipe of C. comatus fruit bodies and their antioxidant properties were studied. Ethanolic extract from stipe showed high antioxidant activity (80.6%) at 1 mg/mL. Reducing power of hot water extracts from cap was 1.653 at 10 mg/mL. Ex...

This study was conducted by trapping airborne fungal spores inside and outside 15 residences in Kitchener-Waterloo, Ontario, Canada, monthly from December 199 1 to September 1993. The dominant fungal propagules recorded indoors were Cludosporium (38.8%),Aspergillus/Penicillium (1 9.8%), Leptosphaeria (7.9%), unidentified basidiospores (6.5%), unidentified ascospores (2.8%), Ganoderma (2.6%), Al...
