Phenologie des Basidiomycetes lignicoles de l'ile de Laing (Papouasie Nouvelle-Guinee)

In the framework of a study of wood-inhabiting fungi on Laing Island, a small coral island located on the northern coast of Papua New Guinea, we have established a phenological table of the 96 taxa of encountered Basidiomycetes. Within six species presenting large phenological amplitude, two groups can be distinguished. On the one hand a group of species (Hexagonia tenuis, Polyporus philippinensis and Microporus xanthopus) with narrow ecological amplitude restricted to dense vegetation cover and thus growing in an environment buffered against desiccation and on the other hand a group of species (Pycnoporus sanguineus, Schizophyllum commune and Trametes scabrosa) with a very large ecological amplitude very resistant to desiccation. Furthermore, a large number of species are found too sporadically in order to draw some conclusions concerning their phenology.
