Piptocephalis curvata Baijal & B. S. Mehrotra, Zentralbl. Baktedol. Parasitenk. Infektionskrankh. Hyg. 2. Abt. 122: 181-184. Figs. 1-18. 1968.
Description：
Aerial mycelium fine, hyaline. Sporophores growing from vegetative mycelium, erector ascending, hyaline, smooth, becoming septate in age; main stalk simple, 10-62.5 μm high, narrowest at the base, gradually enlarging upward to about 4.5-5.8 μm wide, forming fertile branch system on top, which consisting of 3 to 6 successive dichotomies; ultimate branches mostly curved, (5-)10-25 × 1.5-2.5 μm; penultimate branches 15-22.5(-50) × 2.0-3.8 μm; head-cells deciduous, hyaline, with stalks, usually furrowed to form 4 lobes on top, each lobe studded with 3-4 projections bearing up to 16 merosporangia per head, 5.0-6.5(-8) μm diam; merosporangia 2-spored, initially oblongly ellipsoidal, later the apical spore blown out to form a ± cylindrical merosporangium with a circumscissile restriction,10-13 μm long; spores barrel-shaped to ellipsoidal with blunt ends, two distinct oil droplets visible inside, smooth-walled, becoming brownish, 5-7 × 2-2.5 μm; spore-heads forming a liquid droplet at maturity. Zygospores not observed.
Specimens：
Symg0108, parasitized on Backusella circinella, isolated from soil, Yangmingshan, Taipei, Jan. 2001.
The fungus is characterized by: Firstly, the curvature ultimate branches of sporophores; secondly, the fertile successive dichotomies; thirdly, the lobed head cells and then, the 2-spored merosporangia (Grafenhan, 1998).
