30. Lactarius chrysorheus Fr. 



Plates 25 and 40. 



Cap up to 8 cm. broad, deeply depressed in center, often quite 

 irregular and aborted on one side, margin strongly incurved until 

 maturity and then not at all incurved, faintly or hardly at all tomen- 

 tose when young, smooth afterwards, or tomentose on very margin 

 nearly to maturity; surface viscid, quite smooth, pale maize-yellow 

 or even lighter with faint zones of a dotted appearance. Flesh about 

 5 mm. thick near stem, soft but rather rigid and brittle ; milk sparse, 

 white, then greenish-yellow (about sulphur-yellow), very acrid and 

 with a very disagreeable fishy taste, which is entirely different from 

 the taste of any of our other species. The odor is similar, but not so 

 strong. 



Gills crowded, slightly decurrent, only 2-4 mm. wide, whitish when 

 young, turning a rather light creamy buff, with a tint of pink in edge 

 view. 



Stem about 2.5-5 cm. long, 1.3-1.8 cm. broad at cap, tapering down- 

 ward, whitish or colored like the cap, smooth, pruinose at top, marked 

 by numerous, irregular, scrobiculate spots that are scarcely or not at 

 all darker than the rest, hollow in center. 



Spores (of No. 1838) white or faintly creamy, subspherical, 

 warted, 5.8-6.3 x 5.8-7.2/*. 



The distinctions between this species and L. theiogalus are not con- 

 spicuous. The gills in the former are lighter, and the zones on the 

 cap are made up of dots, also the milk is more peppery and with a 

 very bad fishy taste. The spores also afford a means of distinction ; 

 in L. chrysorheus they are essentially white, in L. theiogalus they are 

 distinctly cinnamon.
