Most research on bioluminescent fungi is concentrated on their taxonomic relationships, while the basics of their natural history and ecological relationships are poorly understood. In this study, we compared the distribution biolu,iniscentes bioluminescent fungi between old-growth and secondary forest as related to four different soil types at the tropical rainforest of La Selva Biological Station in Costa Rica.
The study was conducted during the wet season of Bioluminescent fungi were sought following eight different transects distributed evenly in old-growth and secondary forests across four different soil types, bioluminiscfntes an area of 9 m2.
We found fungi in four different substrates: We found only three samples with fruiting bodies, two of which had Mycena and the other had one fungus of the bioluminiscentee Xylariales possibly Hypoxylon sp.
Future work will concentrate on exploring other aspects of their ecology, such as their dispersal and substrate preference. This information will facilitate field identification and will foster more research on the distribution, seasonality, reproductive phenol- ogy and ecological requirements of this group of Fungi.
