Piptocephalis fimbriata M. J. Richardson & Leadbeater, Trans. Brit. Mycol. Soc. 58: 205-215. Figs. 1-3. 1972.

 Description: Sporophores growing from mycelium in agar media, ascending, later prostrate, hyaline, remaining smooth or becoming slightly striated and septate in age; main stalk simple, up to 1.5 cm long, about 3.0-4.2 μm wide, forming fertile branch system on top, which consisting up to 5 successive dichotomies, ultimate branches15-35(-52) × 1.5-2.0 μm; penultimate branches 15-22.5(-50) × 2.0-3.8 μm; head-cells deciduous, hyaline, studded with projections bearing 11(-26) merosporangia per head, 5-6.5(-8) μm diam, lysing at maturity to leave a ragged fringe at the tip of the sporophores; merosporangia (2-)3-4(-5) spored, 12-14.5 × 1.8-2.2 μm ; spores cylindrical with two truncate ends or round at one end, (4-)4.5-5 × 2 μm, distinct oil droplets usually present, smooth-walled; spore-heads forming a liquid droplet at maturity. Zygospores not observed.

 Note: This fungus bears the distinguished characteristics of P. fimbriata in having fertile, dichotomously branching sporophores; head cells smaller than 7 μm in diam which are lysing at maturity, leaving small fringe at the tip of sporophores, and the ultimate branches usually longer than the penultimate branches (Grafenhan, 1998; Kirk, 1978). However, the long main sporophores of this isolate which is up to 1.5 cm is reported for the first time in this paper.
