OMPHALIA FLAVIDA 



411 



" Very minute, yellowish ; pileus thin, membranaceous, hemi- 

 spheric-campanulate, depressed or subumbilicate in the centre, then 

 more or less flattened, glabrous, radially striate, 1-5-2 -5 mm. in 

 diameter, with an acute margin ; stipe setiform, straight, thin, of 

 the same colour, very minutely velvety, about 1-1-5 cm. long,^ 



Fig. 207. — Ornphnlia flavida. Plan of under side of the pileus of an 

 expanded fruit-body, to show the arrangement of the gills. The 

 fniit-body was removed from a Bryophyllum leaf which had been 

 inoculated with gemmae 40 days previously. Drawn by A. H. R. 

 Buller and Ruth Macrae. Magnification, about 15. 



0-25 mm. thick, the base not swollen. Gills few, rather distant, 

 yellowish, somewhat waxy, triangular, attenuated at each end, 



1 Maublanc and Range], in their general description of the fungus {loc. cit., 

 p. 43), give the height of the fruit-body as about 1 cm. (hautd'environun centimetre), 

 but in their diagnosis they say the stipe is " circ. 1 • 5-3 mm. longo." This discrepancy 

 seems to be due to a misprint in the diagnosis, as the authors' illustration shows the 

 fruit-body a little more than 1 cm. high. Ashby {loc. cit., p. 327) states that the 

 fruit-body is 1-1 • 5 cm. high, and my experience is the same as his. I have therefore 

 emended the diagnosis of Maublanc and Rangel by substituting 1-1-5 cm. for 

 1-5-3 mm. Ashby gives the width of the pileus as 2-3 • 5 mm.
