TAILIEUCHUNG - Mycorrhiza between Kobresia bellardii (All.) Degel and Terfezia boudieri Chatin
Desert truffles collected from the Tarom region in Iran were investigated in the laboratory. According to microscopic and macroscopic studies, the species was identified as Terfezia boudieri Chatin. Field and laboratory studies showed that Kobresia bellardii (All.) Degel has ectomycorrhizal associations with Terfezia boudieri in the study area. | Turk J Bot 32 (2008) 17-23 © TÜB‹TAK Research Article Mycorrhiza between Kobresia bellardii (All.)

According to microscopic and macroscopic studies, the species was identified as Terfezia boudieri Chatin. Field and laboratory studies showed that Kobresia bellardii (All.) Degel has ectomycorrhizal associations with Terfezia boudieri in the study area. Key Words: Terfezia, mycorrhizal associations, sedges Introduction Kobresia bellardii (All.) Degel is a monocotyledonous angiosperm herbaceous plant species with a wide geographical distribution, and is found in relatively snowfree habitats (Atherine et al., 1979; Massicotte et al., 1998). It is a particularly successful species in the alpine meadows of the Front Range and strongly dominates plant cover in many sites that are not extremely wind exposed, such as fell fields, or buried under snow in winter (Atherine et al., 1979). Willard (1963) noted that young Kobresia plants were rarely found and that some meadows may have taken as long as 1000 years to develop to their present state, usually forming up to 55% of the plant cover (Willard, 1963; Atherine et al., 1979). Most macrofungi species that produce macroscopic hypogeous sporocarps are ectomycorrhizal, with Basidiomycetes or Ascomycetes (Miller et al., 1999) commonly referred to as truffles. Truffles are hypogeous fruit bodies produced by many genera of macrofungi belonging to the class Ascomycetes. Among these, Terfezia and Tuber (Tuberaceae) are classified in different taxa of the Pezizales (Norman & Egger, 1999; Percudani et al., 1999; Bejerano et al., 2004). Fungi belonging to the family Pezizaceae form either terfeziatype ectomycorrhiza or .
