S ummary Details are presented of ectomycorrhizas in seventeen genera of tropical angiospermous trees from six families. Mycorrhizas of Intsia, Melaleuca, Monotes, Neea, Tristania and Vateria are figured for the first time. Overall, the tropical mycorrhizas are of a smaller diameter than is typical for those of temperate angiosperm trees but the sheaths are thicker and the fungus can form up to about 80% by weight of the dual organ. Our observations do not support the notion of a higher degree of host/fungus specificity in the tropics than in the temperate zones.
