Myceliophthora fergusii （Klopotek） van Oorschot, Persoonia 9: 406. 1977.
Description：
Colonies on YpSs grow rapidly, reaching 76 mm at 40°C in 3 days; irregularly scattering in groups, floccose or powdery; The color shows white at first, Seashell Pink, then turn to Pinkish Buff; reverse Cinnamon-Buff.
Hyphae smooth-walled, septate. Fertile hypae unbranched or irregularly side branched up to 5.8 μm in width. Blastic conidia pale yellowish green, born terminal or laterally on fertile hyphae, sessile or 1-3 conidia grown on ampulliform swelling on short protrusions; conidia globose to subglobose, (4.5-7.5 μm), ovoid to elliptical (5-8 × 5.6-9.5 μm) ovoid to elliptical (5-8 × 5.6-9.5 μm) with smooth at young, few slightly roughed at maturity.
No teleomorph was found in present study.

Temperature tests: The optimum temperature of growth and conidium production is be-tween 35°C and 50°C. The minimum temperature is 25°C (Table(2).)
It is a thermophilic fungus (Table 2) and new record from Taiwan. M. fergusii has a known teleomorph: Corynascus thermophilus (Fergus & Sinden) Klopotek, but teleomorph stage of this isolate has not been observed. Morphology of M. fergusii is similar to M. ther-mophila, but have the following differences: (1) conidial wall of M. fergusii are smooth (van Oorschot, 1980), while M. thermophila are smooth at young, and predominately warty structure at maturity. (2) the fertile hyphae of M. fergusii are wider than those of M. ther-mophila. M. fergusii are up to 6 μm and M. thermophila are < 4 μm (Klopotek, 1974, 1976; van Oorschot, 1980).
