  Oyster fungi \emph{Pleurotus djamor} generate actin potential like spikes of
electrical potential. The trains of spikes might manifest propagation of
growing mycelium in a substrate, transportation of nutrients and metabolites
and communication processes in the mycelium network. The spiking activity of
the mycelium networks is highly variable compared to neural activity and
therefore can not be analysed by standard tools from neuroscience. We propose
original techniques for detecting and classifying the spiking activity of
fungi. Using these techniques, we analyse the information-theoretic complexity
of the fungal electrical activity. The results can pave ways for future
research on sensorial fusion and decision making of fungi.
