Summary A case of an autochthonous toenail infection caused by Hendersonula toruloidea is presented. H. toruloidea was characterized by thick, branching septate brown‐walled hyphae of a non‐dermatophyte in microscopic tissue mounts in 25 % Na0H with 5 % glycerol. Cultures grew out on Littman's agar and Sabouraud peptone glucose agar plus chloramphenicol, but only if cycloheximide was not present. In vitro, the H. toruloidea isolate was characterized by copious 1‐to 2‐celled hyaline to dark‐brown arthroconidia deriving from the fragmentation of aerial hyphae. It is likely that more infections due to H. toruloidea will be diagnosed if cycloheximide‐free media are routinely used in the isolation of organisms from suspected dermatophyte infections.
