1S6 THE AGARICACEAE OF MICHIGAN 



Ionia ruMcunda Pk. is doubtless H. Russula in spite of the argument 

 for its autonomy by E. M. Williams in the Plant World, Vol. 4, p. 

 9, 1901. H. erubescens Fr. is similarly colored, but consistently of 

 a different habit, long stemmed and narrow-capped. - The latter 

 species as I saw it in Sweden, seems to me to be quite distinct. 



164. Hygrophorus pudorinus Fr. (Edible) 



Syst. Myc, 1821.

PILEUS 2-10 cm. broad, firm, convex-campanulate, subexpanded, 

 obtuse, viscid when moist, pale tan color, pinkish-buff or tinged in- 

 carnate, glabrous, even, margin at first involute and minutely 

 downy. FLESH compact, thick, white or tinged flesh-color. GILLS 

 acuminate-subdecurrent, subdistant, thickish, narrow, sometimes 

 forked, interspaces venose, usually connected at the stem by a nar- 

 row border, trama of divergent hyphae. STEM 3-8 cm. long, 5-20 

 mm. thick, stout, compact, solid, dry, equal or tapering downward, 

 white, buff or incarnate-tinged, floccose-scabrons at apex, floccose- 

 fibrillose or glabrescent downwards. SPORES cylindric-elliptical, 

 smooth, 6-9x3.5-5 micr. BASIDIA slender, 45-50x6-7 niicr., 4- 

 spored. ODOE and TASTE mild. Edible. 



Gregarious to caespitose. On the ground, often among grass, 

 in hemlock or frondose woods or thickets. Ann Arbor, Detroit, 

 New Richmond. September-November. Frequent. 



This is a variable species with us as regards size and coloration. 

 Late in the season a small form appears (form minor) which has 

 always a white stem, and forms considerable patches in oak woods. 

 It is possible that this form is H. arbustivus Fr. In the typical 

 and luxuriant specimens of H. pudorinus the stem is tinged flesh- 

 color to pale isabelline. Occasional specimens are larger than the 

 sizes given above, which are made to include form minor. All of 

 these are delicious food.
