Abstract

An ascomycetous fungus was collected from twigs of oriental plane tree (Platanus orientalis L.) from forest park of Kerman in April 2008 that was identified Preussia typharum (Sacc.) Cain [CAIN, R.F. 1961. Studies of coprophilous ascomycetes. Can. J. Bot. 39: 1633-1666; VALLDOSERA, M. & GUARRO, J. 1990. Estudiossobre hongos coprófilos aislados en Espana. XV. El ġénero Preussia (Sporormiella). Bol. Soc. Micol. Madrid 14: 81-94]. This is the first report of this fungus from Iran. A description of the fungus is given bellow:Ascocarps scattered, partly immersed in the bark, brown when young turning to black at maturity, globose to subglobose, shining, glabrous, non-ostiolate, splitting irregularly, without definite cleavage area, 250–350 mm in diam. (Fig. 11 A); peridium thin, membranous, dark-brown with shades of light red, consisting of thick-walled, angular (textura angularis) to isodiametric (textura epidermoidea), 5–7.5 mm cells (Fig. 11 B); asci vary in shape from cylindrical-clavate, 50–60 × 15.5–19.5 mm, to broadly clavate, 43–50 × 26–30 mm, 8-spored, with long stipes measuring 30–48 × 2.5–4.5 mm, lying in a parallel layer attached at the base of ascocarps, with crozier at base, bitunicate with thick and persistent wall when young, evanescent when mature, but not elongating in water to discharge ascospores (Fig. 11 C-E); ascospores crowded in a partially overlapping fascicle lying parallel with ascus, arranged tri-seriate at above and bi- or uni-seriate at below or rarely bi- or tri-seriate at the whole length of cylindrical-clavate asci and tri- or four-seriate at the whole length of broadly clavate asci, 4-celled, fusiform-cylindrical, 27–30 × 7.5–9 mm, deeply constricted at transverse septa, easily separable at all septa, straight or rarely slightly curved, smooth, hyaline at first, then olivaceous brown to light brown, finally very dark brown and opaque at maturity, with a large guttule when mounted in water (Fig. 11 F), mainly with parallel to oblique, rarely diagonal germ slit, sometimes with a kink near the middle (Fig. 11 H), end-cells distinctively longer than mid-cells with slightly to distinctively attenuated ends (conical to sub-conical), measuring 8.5–10.3 × 6.5–8 mm, mid-cells globose to distinctively barrel-shaped, measuring 7–8.5 × 8–8.5 mm (Fig. 11 G).Closest species to P. typharum is P. fleischhakii (Auersw.) Cain (CAIN 1961, VALLDOSERA & GUARRO 1990), which resembles P. typharum in ascocarps, peridium, asci and ascospores characteristics, is distinguished from that by possessing asci with very short stipes (reaching 10–14 mm in length), longer and narrower ascospores (26–35 × 6.5–7.5 mm), with narrower end-cells, measuring 8–10 × 6–7 mm and shorter and wider mid-cells, measuring 5.5–7.5 × 6–7.5 mm.
