6 Clavarias of the United States and Canada 



In addition to the genera above mentioned and those discussed 

 under the genus Clavaria, there have been several others proposed. 

 Patouillard in his Essai taxonomique Hymen., p. 44, 1900, has got 

 these together in convenient form and adequately defined them. 

 For convenience I give below his descriptions of the genera now 

 accepted by him, but not treated by me, and not yet fully accepted 

 by mycologists. 



Ceratclla (Quel.) Pat. Hymen. Eur., p. 157. 1887. ( Used as 

 a sub-genus or group name by Quelet in Enchiridion, p. 222. 

 1886) : 



"Waxy or tough, filiform, simple or branched, sessile or stipi- 

 tate, ending in a point. Hymenium surrounding the middle part 

 of the plant, lacking at the base and at the top. Flesh formed of 

 parallel, not very numerous hyphae, septate, often encrusted with 

 calcium. Basidia as in Pistillaria; cystidia pointed, projecting, 

 delicate, small; spores hyaline, smooth. Small species, reviving 

 when moistened, growing in colonies on vegetable debris. Ex- 

 amples are C. aciilcata, C. Queletii, C. Hclcnac, C. macrospora, C. 

 acuminata." [All as Pistillaria in Sacc. Syll. 6: 758, and 11 : 142. 

 If this genus is accepted difficulties will arise with other species 

 now included in Clavaria. For example, C. vemalis has a conspicu- 

 ous sterile tip, which is usually covered with crystals in the dry 

 state. Other well known species of Clavaria, as C. aurantio-cinna- 

 barina, C. filipes, and sometimes C. hck'cola, have sterile tips which 

 in drying shrink less and take a different color, appearing like 

 little caps set on the ends of the clubs] . 



PistiUina Quel. Compt. Rend. Assoc. Fr., 1880, p. 671. 1881. 

 (Sphacrula Pat. Tab. Fung., fasc. 1, p. 27. 1883). 



"Receptacle quite small, erect or hanging, slightly tough, 

 formed from a cylindrical stem, glabrous or tomentose, enlarged 

 at the top into a convex disk covered by the hymenium and some- 

 times edged with hairs. Flesh filamentous as in Pistillaria. Ba- 

 sidia with 2-4 sterigmata. Spores hyaline, ovoid, smooth." 



Here belong P. hyalina, P. bruiuicola, P. capitata. [All as Pis- 

 tillaria in Sacc. Syll. 6: 759. This genus seems to me to belong 

 very doubtfully in the Clavariaceae, but probably to be related to 

 Cyphclla in the Thelcphoraceae].
