"Plants simple, solitary or in gioups of 3-7, 2-4 cm. high, 

 fragile, bright rose-pink; taste and smell none. Clubs slender, 

 cylindrical or compressed, equal or tapering upwards, smooth, 

 solid, 2-5 mm. thick, apex blunt or pointed. Stem fairly distinct, 

 paler, sometimes yellowish. Flesh whitish, deep rose beneath the 

 hymenium. Internal structure of frequently septate, irregular 

 hyphae, 7-\2\k in diameter, semi-parenchymatous in transverse 

 section; crystals sometimes present. Basidia conspicuous, 35-40 

 x 7-10[x, granular or guttulate, sterigmata 4, erect. Spores copi- 

 ous, smooth, hyaline, ovoid or broadly elliptical, 7-10x 5-6[/.. 

 Amongst grass, moss, etc. Rare. . . . Easily distinguished from 

 other British species by the bright, rose-pink colour." 



See under C. helveola for remarks on C. incarnata which may 

 be the same as C. rosea. 



It is not known which of the above interpretations is repre- 

 sented by the illustrations by Krombholz and Winter given below. 



On account of the confusion involved in the publication of C. 

 rosea and C. Swartsii, it is well to explain that Swartz first used 

 the name C. rosea in Acta Holm, (see above) as a manuscript 

 name of Dalman's for a species which the latter intended to de- 

 scribe. Swartz says (translation) : "Herr Dalman who has seen 

 the greater part of these species growing in Westergotland has 

 also communicated to me information about a new species which 

 he has found, which he intends to describe under the name of C. 

 rosea; it is shorter with entirely white foot. Clubs bent but not 

 twisted, rose and yellow color at top." Later Dalman (J. W., not 

 Olaus, as given by Lindau and Sydow) published as C. Swartsii 

 a plate in Svensk Botanik (see above). This was evidently the 

 publication referred to by Swartz. Still later Fries (Obs. Myc. 

 2: 290, pi. 5, fig. 2. 1818) described the plant more fully and ac- 

 cepted Dalman's name C. rosea as published in Swartz's work. 

 He did not, however, refer here to C. Szvartsii as a synonym, but 

 did so in his later work.
