Notes on the rhizomorphs and mating system of Xeromphalina campanella

Xeromphalina campanella (Batsch: Fr.) Kuehner & Maire is a common mushroom in northern coniferous forests, most often found fruiting in large clusters on old, well-decayed conifer stumps and logs. Although the taxonomy of Xeromphalina has been discussed, there is little information on the general biology of the genus. Here we summarize the information on decay, rhizomorph morphology and spread of X. campanella .
