Piptocephalis tieghemiana Matruchot, Bull. Soc. Mycol. France 16: 58-64. 1900.

 Description: Colonies growing on Mucor sp. on CMA at 24℃ at first hyaline becoming Buff at maturity. Sporophores arising from the media, erect or ascending; main stalks 6.5-10 μm wide, becoming distantly septate in age; this and the lower portion of the fertile branch system becoming distinctly longitudinally striate in age; the fertile branch system consisting of up to 7 successive dichotomies; branches of primary dichotomies often relatively short, 12.5-44 × 5-10 μm, each giving rise to long branches up to 200 μm long, becoming distantly septate; septa simple; penultimate branches 5-16 × 2-4 μm; ultimate branches 5-14 × 1.2-2.5 μm; head-cells deciduous, globose or obconical, 4-4.5 × 4-5 μm, bearing 20-30 merosporangia; merosporangia 6.8-7 × 2-3(-3.5) μm, containing 2 spores; spores bullet shaped, smooth-walled, 4-5 × 2-3 μm; spore-heads remaining dry at maturity. Zygospores not observed.

D94032401, parasitized on Mucor sp, isolated from mouse dung, Sindian, Taipei County, March, 2005.

 Note: This fungus is identified as P. tieghemiana based on the following distinguished characters: spore heads remaining dry when mature; deciduous, small, globose head cells; 2-spored merosporangia and dichotomously branching fertile system. The closely related species P. lepidula (Marchal) R. K. Benjamin differs in the mode of distal spore formation which is budding from the basal one (Gr?fenhan, 1998; Zycha, 1996).
