Fungi-orchid relationships have been studied mainly in terrestrial orchids. The present work deals with diversity andbiological role of the fungi associated to the epiphytic orchid Laelia speciosa through molecular evidence. ITS sequences confi rmedfungal presence in roots, capsules, seeds and in vitro seedlings. None of the fungi found formed characteristic pelotons, sowe do not assume they are mycorrhizal. We identifi ed 18 taxa of fungi belonging to eight known genera (Alternaria, Curvularia,Cylindrocarpon, Fusarium, Myrmecridium, Neonectria, Penicillium, and Tetracladium) and unknown species of Atractiellales,Helotiales, Hypocreales, Lasiosphaeriaceae, Nectriaceae, Sordariomycetes, and Tricholomataceae. From these, we infer the biologyof nine parasites, four saprobes, and two endophytes. One of the fungi, a Helotiales species, was able to colonize all orchidtissues, including seeds and in vitro seedlings, so, even if all precautions were taken, “axenic culture” of L. speciosa is a diffi culttask. There is a considerable diversity of fungi within L. speciosa organs. Endophytic fungi interact with the whole plant of L.speciosa along its life cycle.

Molecular evidence reveals fungi associated within the epiphytic orchid Laelia speciosa (HBK) Schltr.
