72 Clavarias of the United States and Canada 



Brit. Myc. Soc. 3: 184. 1909). As Persoon himself considers C. 

 grisea and C. cinerea as synonyms of C. fuliginea (Myc. Europ., 

 p. 166) we are safe in disposing of it here. Clavaria fuliginea 

 as determined in the Schweinitz Herbarium is C. cinerea, with 

 spores 6.5 x 7. 5 p.. In the Curtis Herbarium plants so labelled are 

 C. amethystinoides. Fries considers C. trichopus a synonym of C. 

 cristata, and plants in Bresadola's herbarium (Cavelante) so de- 

 termined are a form of C. cristata with spores subspherical, 

 5.5-7.4 x 6-8;/.; basidia 5.5-6.2fj. thick with two sterigmata. Clav- 

 aria albida in Bresadola's herbarium is also C. cristata, with spores 

 oval to subspherical, 6-7.5 x 7.5-9[/.. We have received also two 

 collections from Romell (Sweden) labelled C. albida which are the 

 same. The white form often swollen upward, such as ours from 

 Redding, Conn., is the one that is at times referred to C. coral- 

 loides by European botanists, as Romell. The C. coralloidcs of 

 Persoon's herbarium is a large branched plant that might pass for 

 a highly developed form of C. Krombholsii except for the spores, 

 which are so different as to exclude it. They are subelliptic, 

 slightly rough, 4-4.8 x 10.5-13|i. That Fries's idea of C. macropus 

 Pers. is the Krombhohii form of C. cristata is shown by a good 

 collection by him (Upsala) at Kew (spores smooth, oval, 

 6.6-7 x 8-8. 5{a). This is also the disposition of the species by 

 Bresadola. In his herbarium is a plant so named which is easily 

 seen to be a small form of C. rugosa, with spores "8-9 x 7.5-8.5[a." 

 The species is not represented in Persoon's herbarium, and so 

 must remain doubtful. If the C. dicJwtoma Godey distributed by 

 Roumeguere as No. 31 15 of his Fungi Gallici exsiccati is authentic, 

 the name is a synonym of C. cristata. An example at Kew is like 

 the latter in appearance and has the same spores, 5-6.5 x 6.3-7 Aiu. 

 However, Bourdot and Maire (Bull. Soc. Myc. Fr. 36: 72. 1920) 

 give the spores as smaller, 3.5-4 x 4.5-5(1. Otherwise their de- 

 scription does not exclude a form of C. cristata. Saccardo pro- 

 posed the name C. Schaefferi to represent C. lilacina Fr. and C. 

 purpurea Schaeff. He gives the spores of the plant he had in 

 mind as 8-10 x 6-8(jl, which show it to be the purplish form of C. 

 cristata. Schaeffer's plate looks so much like what we are calling 

 C. amethystina that it would be so referred with confidence except 

 for the large spores figured on the same plate. Clavaria coliformis 

 Boud. (Bull. Soc. Myc. Fr. 33: 11, pi. 3, fig. 2. 1917) is probably
