Abstract

We report a rare case of non-dermatophytic onychomycosis of the toenail caused by Phoma macrostoma. Was studied the biological properties of the strain isolated in Kazakhstan. P. macrostoma forms pink colonies, the reverzum is pink-orange. The mycelium is colorless, septate. The appearance of growth tubes from pycnidospores occurs within 12 hours, mycelial growth and branching after 18 hours, the appearance of pycnids is 48 hours. The saccharolytic and urease activity of the strain is low.
