Locus	Cultural Requirements	Link Group	Type
eas	IIR. Linked to rip-1 (1/151), trp-3 (0/71), and fl (1/52) (PB). (967)Conidia and aerial hyphae are readily wetted by water; in contrast, those of wild type are hydrophobic. Resembles csp mutants in that conidia do not readily become airborne, but differs from csp mutants in that conidia do not remain joined in the proconidial chains (967). Rodlets are lacking from the surface of conidia (75). Conidiating cultures can be scored by adding a drop of water to the culture, by tapping an inverted slant (967), or by transferring conidia to liquid (PB). Not scorable in combination with fl. Somewhat sensitive to high osmotic pressure (PB). A class of slow-growing progeny is produced from crosses heterozygous or homozygous for eas(811).	IIR	B
trp-4	IVR. Between his-5 (3 to 7%) and leu-2 (1 to 2%) (633, 991). (47). Uses tryptophan or indole (750). Deficient in anthranilate phosphoribosyl transferase (1126) (Fig. 11). Scorable by blue fluorescence (anthranilate) in medium under long-wave UV after 2 to 5 days of growth on minimal medium plus indole (10 µg /ml), 34°C. Initial stocks of the first trp-4 mutant were inhibited by suboptimal concentrations of tryptophan (750), but derivatives have been obtained that are free of this problem (909).	IVR	B
