On the hymenium of Lactarius deliciosus. Whitfield and Merry- 
hill Common, near Hereford, 1874; Coed Coch, Oct., 1880. 
This is quite distinct from Hypomyces torminosus , with which it 
seems to be confounded by some Continental fungologists. It is 
thicker, more fleshy, and, especially in the earlier stages, frosted 
over with white meal.

in amount and colour.

At first forming a thin white floccose web upon the gills of the 
Lactarius, which gradually becomes pale yellow, then honey- 
coloured, and eventually, when the specimen dries, assuming a 
chocolate-brown hue.

5. Hypomyces xosellus, Tul. Conidia : Flocci aggregate, branched, 
white, branchlets numerous, 3-6, verticellate, bearing terminal 
conidia, which are hyaline, cylindrico-oblong, obtuse ; 2 or more, 
usually 3, septate ; ’025 to ’035 mm. long by *01 to *013 mm.

Perithecia gregarious, emerging from a thin subiculum of an 
open texture, which is at first white, then rose-coloured ; spheroid-
