Macro-fungi from different places of   Mazandaran and Tehran provinces, collected since 1982-2000, identified. An account of 16 Coprinus species, namely, Coprinus picaceus, C. cinereus, C. lagopus, C. lagopides, C. macrocephalus, C. brunneofibrillosus, C. subimpatiens, C. angulatus, C. niveus, C. ephemeroides, C. comatus, C. flocculosus, C. scobicola, C. disseminatus, C. plicatilis and C. patou...

First, the enzyme reacts with one peroxide equivalent resulting in oxidation of the haem iron to the oxyferryl, Fe(IV-0), centre and an organic radical, R', where R' is either the porphyrin or an amino acid-centred radical. Next, Compound I oxidizes one substrate molecule to give a substrate radical and Compound 11. Finally, Compound I1 is reduced by a second substrate molecule to the resting, ...

Patterns of mating and mitochondrial DNA (mtDNA) inheritance were investigated for the Basidiomycete, Coprinus cinereus in order to better understand the relationship of reproductive biology and mtDNA evolution in fungi. Results showed that the unique mating system of basidiomycetes can lead to the formation of mitochondrial mosaics (i.e., colonies composed of sectors differing in mtDNA). Mitoc...

Removal of large segments of the apical part of the stipe of Coprinus cinereus (extending to about half its length) affected neither the ability of the stipe to show gravitropic bending nor its ability to compensate the curvature so induced and adjust to the vertical. However, gravitropic reaction time was directly proportional to the amount of stipe removed. Application of lateral loads of up ...

A hymenial cell initial was binucleate in Coprinus cinereus but uninucleate in Volvariella bombycina. Paraphyses and facial cystidia remained binucleate in C. cinereus, but marginal cystidia were the apical cells of branches from the multinucleate gill trama. becoming swollen when gills pulled away from their connection to the stipe, and were multinucleate. In V. bombycina. all mature cystidia ...

Mathematical models which imitate plant gravitropic responses were used to compare plant and fungal gravitropism with kinetic data from the agarics Coprinus cinereus and Flammulina velutipes. Similarities were: bending depends on differential growth; growth of the organ is most intensive just behind the apex; gravitropisms exhibit a substantial time delay. Differences were: the agaric stem apex...

In this study, decolorization of the diazo dye, Reactive Black 5 (RB5) in a Coprinus cinereus peroxidase-catalyzed reaction has been investigated. A bisubstate kinetic model for the reaction rate based on the Ping-Pong mechanism was assumed for the enzymatic decolorization. Experiment...
