GENERA AND SPECIES OF MUSHROOMS 



Gills broad; rounded near stem or base; radiating from a 

 lateral (marginal) hairy spot; whitish when young, turning 

 brownish-rusty when old. 



Stem very short or absent. 



Spores rusty-colored; elliptic; often with a nucleus; .0003 

 to .0004 inch by .0002 to .00025 inch in diameter. 



A pretty species. The cuticle (peel) is separable and is 

 tenacious though it has a jelly-like appearance. Specimens 

 dried in their place of growth are not rare. Peck. 



Crepidotus malachius; soft-skinned crepidotus. Species 

 47. Figure 17. 



On damp, decaying wood in woods or shaded places. Much 

 decayed, mossy trunks of trees constitute a favorite habitat; 

 scattered; in groups or with the caps overlapping; June to 

 September. 



Cap fleshy, thicker on the margin, and at the base; circular, 

 kidney-shaped or wedge-shaped; convex or nearly plane; 

 smooth or hairy at the base; water-soaked in appearance when 

 moist (hygrophanous) ; watery-white and mth faint radial 

 lines (striations) on the margin when moist, white when dry; 

 flesh white; i to 2>^ inches broad. 



Gills thin; close together; rounded near the stem or base; 

 white or whitish, becoming rusty when old. 



Stem absent or very short; placed at the margin of the 

 cap. 



Spores rusty; globular; .00025 to .0003 inch in dia- 

 meter. 



In wet weather it has a water-soaked appearance. As the 

 moisture escapes, the cap becomes a clearer white. The mois- 

 ture disappears from the thickest part of the cap first, the 

 thinnest part last. The species may be distinguished from 

 other white and closely resembling forms by its smoother cap 

 and globular spores. Peck.
