1 Introduction he present article is a contribution to the study of the spe- cies composition and distribution of the operculate disco- mycetes (Pezizales) in Bulgaria. Data on 16 species are given. hree of them are reported for the first time from the country, viz. Otidea propinquata, Peziza depressa, and Pseudoplectania sphagnophila. New localities are reported for 13 other spe- cies. Among them Helvella ephippium, Octospora humosa, and Trichophaea hybrida are rare species (Breitenbach & Kränzlin 1984; Dennis 1978) and are reported for the second time in Bulgaria. he new species for Bulgaria are presented with concise description and are illustrated. he same is also done for the rare species, which were previously reported with chorological data only (Aleksandrov 1971; Hinkova & Fakirova 1970). Material and Methods he investigated specimens were collected from a few floris- tic regions of Bulgaria in 2000. Macroscopic features of fresh specimens were recorded within several hours of collection. Specimens were air dried and packaged in paper bags. Asci, ascospores, and paraphyses were observed and measured af- ter rehydrating of dried material in tap water. Squash mounts were made in iodized lactophenol. Twenty spores from each specimen were measured. All the specimens cited in the paper are kept in the Mycological Collection of the Institute of Botany, Bulgarian Academy of Sciences (SOMF). Determination, nomencla- ture, and taxonomy of the species are in accordance with Breitenbach & Kränzlin (1984), Dennis (1978), and Dissing (2000). List of species New species for Bulgaria Otidea propinquata (P. Karst.) Harmaja, Karstenia 15: 32, 1976. (Fig. 4) Apothecia superficial, gregarious (in groups of 4-5), cup- shaped, 2-2.5 cm in diam, short-stipitate, outside glabrous, ochraceous or brownish; hymenium concolorous; stipe 1.2 cm wide, 0.5 cm high, tomentose, white. Asci 220-300 × 15- 17.5 µm, cylindrical, apex rounded, not blued by iodine, 8- spored. Ascospores (16−) 17.5-20 × 10-11 (−12.5) µm, el- lipsoidal, unicellular, biguttulate, uniseriate in the ascus, hyaline. Paraphyses cylindrical, septate, apices hooked, often forked, 2.5-3 µm wide.
