Babos, Margit: Mycological examination of sawdust depots in Hungary
In one cattle-pen (Csévharaszt) it was possible to examine sawdust mixed with cattle-dung, occurring In forest environment. Here a maBS of coprophilous, littercolous and wood decaying fungi could be found together. The size of the fruit bodies was also large, and also those species grew in groups - large groups - of which this is not characteristic. Gigantism and increased grouping can rather frequently be experienced with fungi living on sawdust, but these two phenomena were even more increased in the case of sawdust with dung. In the course of the examinations the importance, in relation of the decaying of wood matter, of the fungi species living on sawdust could be demonstrated very well. The mycelium mass of the frequent and characteristic species' is very great. The dense mycelium interlacing can be seen not only in the areas below the fruit bodies but the mycelium mass also appears from the sagging footprints. The same can be seen if the planks are lifted. The rate of mycelium growth of certain species can be also extremely high. This can be the reason why the fruit bodies appear very shortly (2-4 weeks) after burning of the sawdust even if burning took place through a thick layer (e.g. at Nyírmeggyes: Pluteus patricius; at Budakeszi: Volvariella volvacea) . The humification of mixed sawdust consisting of frondose and coniferous species, is quick. In certain places, the period of site observations was limited by that the carting out of fresh sawdust was stopped, and following this, the wood waste became decayed during 2-5 years to such an extent that the plantage growing on it could cover it. Usually, however, it was not the original plantage that appeared on it again but nitrophilous weed plants of human size (Artemisia vulgaris. Urtica dioica , Lactuca serriola . etc.) covered the decayed sawdust heaps. At depressions in moorlands, however, the reed (Phragmites communis) can become dominant again. The terrain becoming overgrown with grass could be seen only in on site. List of species concerning the localities Ascomycetes Peziza echinospora Karst.-Budakeszi. 16.05.1979.
