Talaromyces oumae-annae Visagie, N. Yilmaz, Seifert & Samson, in Visagie, Hirooka, Tanney, Whitfield, Mwange, Meijer, Amend, Seifert & Samson, Stud. Mycol. 78: 130 (2014) Index Fungorum registration number: 809187 Colonies on PDA covered half the 9 cm plate in 2 weeks at 28–30 0 C, rapidly growing, greenish grey with a white margin, reverse pale orange with a white margin, circular, margin entire, appearance smooth, velvety, flat, slightly raised at the center, white exudate at the center, dense sporulation (Figure 1e.). Conidiophore 85–240 μm (x̄=183) in length and 2.5–3.5 μm (x̄=3.2) in width, hyaline, septate, simple branching phialides flask-shaped, Conidia 3–3.5 μm (x̄=3.3), round or ellipsoidal, single-celled. Notes: The isolate MZ 277272 from this study was similar to Talaromyces oumae- annae of accession number HQ829146 (identity: 548/556, gaps: 4/556). Determination of the quality of seeds The seed coat of most Arachis hypogea seeds was covered with black powdery mass (Figure 6a). Discolorations were observed in few seeds of Vigna radiata and Vigna sinensis (Figure 6c, d). Most of the seeds of Oryza sativa had tiny holes or cracks in them (Figure 6b). According to the observations made, certain varieties contained some abnormal seedlings. The seedlings of Arachis hypogea were normal whereas Vigna radiata and Vigna sinensis had 30% and 10% of the abnormal seedlings with a distinctly short shoot, root and cut-off hypocotyl restricting further growth (Figure 7.). The germination percentage of Arachis hypogea was 20%. No germination was recorded from the seeds of Oryza sativa. Hence, the germination percentage and vigor index could not be calculated. The germination percentage of both Vigna radiata and Vigna sinensis was 100. The seedlings of Arachis hypogea, Vigna radiata and Vigna sinensis showed a vigor index of 585, 2155.5, and 2909, respectively. Seed germination percentages and the vigor indices are summarized in Table 2. ; Published as part of Ganeshalingam, Archchana & Daranagama, ...
