SUMMARY
A new species of Gliocephalotrichum, G. cylindrosporum Wiley & Simmons, is described on the basis of isolates from Thailand soil and decayed vegetation. Two new combinations are proposed as G. simplex (J. Meyer) Wiley & Simmons (syn. Cylindrocladium simplex J. Meyer) and G. microchlamydosporum (J. Meyer) Wiley & Simmons (syn. C. simplex var. microchlamydosporum J. Meyer).
