C. citrina occurs on Distichlis spicata (L.) Greene in the Texcoco region of central Mexico (Pazoutova et al., 1998). Sclerotia are brown to gray, 4-12 X 1-2 nun. Stipes are pale yellow with lemon yellow capitula (Fig. 3a). Capitula are 1 -1.2 mm and papillate. Perithecia are 238-350 X 92-146 p.m. Ascospores are 78-136 X 0.45-0.6 pm. Conidia are elliptical, 3.65-7.2 X 2.5—2.1 pm (Fig. If). The sclerotia contain no traces of clavines or lysergic acid or its peptide derivatives.

Walker (personal communication) found no alkaloids in C. phalaridis sclerotia. Similarly, HPLC analysis at the Inst. Microbiology CAS, Prague failed to detect alkaloids at the ppm level. Preliminary results confirmed the presence of a group of unknown metabolites. No alkaloids were also detected in the sclerotia of new species of ergot C. citrina from Distichlis spicata (Pazoutova et ai, in press).
