St. Mus. 25: 83), this being probably C. botrytis, but later he 

 gave a new name, C. botrytoidcs (above cited), to a plant with 

 short, roughish spores (the real C. botrytis) and referred the 

 species with long, smooth spores (C. rufcsccns) to C. botrytis 

 (Rept. N. Y. St. Mus. 48: 309. 1894. The colored figures, pi. 39, 

 figs. 5-7, are doubtful.) Many of Peck's plants in the Albany 

 Herbarium labelled C. botrytis are really C. rufcsccns. The latter 

 species can be easily distinguished by the tips being a light wine 

 color (pinkish purple), not at all the deep, clear, rosy pink of this; 

 and also by the less brittle texture, bitterish taste and quite differ- 

 ent spores. 



That we have referred the correct plant to C. botrytis does not 

 seem doubtful if we accept the interpretation of C. rufcsccns as 

 expressed by Fries, Krombholz, Britzelmayr, Rolland, and others. 

 Schaeffer's plate 288, on which C. rufcsccns is based, shows a 

 plant with more dull red tips than the clearer pink-red tips of his 

 plate 176 (upper fig.), on which Persoon based his C. botrytis. 

 In Persoon's herbarium there is nothing authentic under this 

 name. There is one plant and a fragment labelled C. botrytis 

 with a question. They are not typical looking, but the spores 

 are about like those of our plants, 4-5.5 x 8-10{i, and are certainly 

 not those of C. rufcsccns (C. botrytis of Maire and others). 

 Bresadola seems to have confused this species and C. rufcsccns, 

 in some cases certainly reversing them, as shown by both the ap- 

 pearance of the plants and the spores. For example, one plant 

 examined in his herbarium, labelled C. botrytis, has spores lon- 

 gitudinally striate, 4-5.5 x ll-16[x, which agrees with our C. rufcs- 

 ccns. Britzelmayr's figure of C. rufcsccns (Clavariei, fig. 16) 

 shows a yellowish plant with dull brown tips ("reddish to brown- 

 ish-red," he says), and Krombholz's fine and unmistakable colored 

 figures (pi. 53, figs. 1-3) of C. botrytis, to which Fries refers, 

 should establish the species definitely. Clavaria acroporphyrea 

 Schaeff. may be this, but the tips are shown and described as 

 purplish and it may be C. rufcsccns. 



British authors, as Stevenson (British Fungi) and Cotton and 

 Wakefield, do not recognize C. rufcsccns, and have evidently in- 

 cluded it under C. botrytis. The C. botrytis of the latter authors 

 (Trans. Brit. Myc. Soc. 6: 172. 1919) is quite a different plant 

 from ours if the spores be considered the distinguishing charac-
