The known host for Ptechetelium cyatheae is the tree fern Cyathea stuebelii.[2] The fungus parasitizes host leaves, producing basidiocarps as small whitish patches that emerge through the stomata. Microscopically, the basidia are auricularioid (tubular with lateral septa) and emerge from thick-walled probasidia. The species has seldom been collected and is only known from Bolivia and Ecuador.[2]
