118 MINOR PRODUCTS OF PHILIPPINE FORESTS 



with gills 2 millimeters deep, free, crowded, obtuse, remaining 

 a long time pale and then turning dark first at their edges. 

 The spores are dark brown and 8 by 4.5 microns. Cystidia are 

 wanting. The stipe is about 9 centimeters high, and 5 millime- 

 ters thick or a little more at the base. It is white or brownish- 

 smooth, hollow, and without an annulus. No odor is observed 

 and the taste is mild. They are eaten by the Bagobos, who call 

 them ligbuk. The fungi grow terrestrial in the forest. 



COPRINUS CONFERTUS Copel. 



Coprinus confertus is gregarious and caespitose, varying great- 

 ly with the weather. The pilous is fleshy, conical, and when 

 grown in dry weather it is very thick. Oppressed, whitish, 

 cottony flakes cover the cap, the margin of which is entire or 

 cleft a few times. During rainy weather, it is thinner and 

 clothed with an evanescent, silky net, and is grayish black, 

 striate, with a tawny or stramineous disk, and lacerate margins. 

 The gills are grayish-black, crowded, lanceolate, free, but close. 

 The spores are ovate, truncate, black, and measure 14 to 16 

 by 7.5 to 9 microns. The stipe is white, smooth, hollow, 

 and in dry weather turbinate, 2.5 centimeters high, 1.5 centi- 

 meters thick, but when rainy it is as much as 16 centimeters 

 high, and 6 to 15 millimeters thick. The base may be slightly 

 subbulbose and has a strong radical cord. The fungus grows 

 on horse manure. (Fig. 9.) 



COPRINUS DELIQUESCENS (Bull.) Fr. 



Coprimes deliquescens has a submembranaceous pileus, which 

 is ovato-campanulate, then expanded, being 8 to 11 centimeters 

 broad, and 4 to 5 centimeters high. It is subrepand, broadly 

 striate, smooth, with a top studded with innate papillae. The 

 stem is hollow, corticate, smooth, and 11 centimeters long, 4 

 to 8 millimeters thick, at length remote, and linear. The spores 

 are lurid black and 12 by 8 microns. This species grows on old 

 stumps. 



COPRINUS FLOS-LACTUS Graflf.^ 



Coprinus flos-lactus grows solitary to gregarious. The pileus 

 is hemispheric, with age becoming flatly expanded: It is 2.5 

 to 4 centimeters in diameter, a light creamy brown and rem- 

 nants of a universal veil remain as a few scattered floccose 

 ■ scales. It is sulcate with the margin entire at first, but later 

 splitting. While young the cap is crisp and brittle, crumbling
