122 Clavarias of the United States and Canada 



the dried state, but have much longer spores. Maire considers 

 C. sangitinea the same as C. flava in sense of Fries and describes 

 it as having red stains with spores 4-5 x9-12[x (Bull. Soc. Myc. 

 Fr. 27:450. 1911). 



In England neither Berkeley nor his successors have recognized 

 C. flava and it may be our plant that they refer to C. aurea. Plants 

 from Europe at the N. Y. Bot. Garden labelled C. flava have been 

 examined. One from Karsten (Finland) has spores like ours, 

 3.8-4.5 x 7.8-1 0\k. One from de Thumen (Bohemia) has some- 

 what larger spores, 3.7-5 x 9-1 2\x. Both look like our plant in 

 the dry state, as does also the one from Saccardo. We have re- 

 ceived a good collection of this from Juel (Upsala) with spores 

 like ours, minutely rough, 3.7-4.2 x 7.5-10[/.. In the Curtis 

 Herbarium is a collection from South Carolina by Curtis and one 

 from the Schweinitz Herbarium. Both look like our plant and 

 have similar spores, in the former they are 3 x 7.5-8[/., and in the 

 latter, 3.8 x 7.5(x. Another plant in the Curtis Herbarium from 

 Society Hill, S. C, labelled C. stricta is also this (spores 

 3 x 7.5-8[x). In the Schweinitz Herbarium in Philadelphia plants 

 from Salem, N. C, and Bethlehem, Pa., are the same. Peck, At- 

 kinson, Mcllvaine, and Hard have also interpreted the species in 

 the same way. It would seem that the American representative 

 of C. flava is a form with somewhat smaller spores. 



Juel (see citation under C. cristata) finds the basidia to be 

 4-spored with the nuclear spindles apical and transverse. He says 

 the species is very similar microscopically to what he considers C. 

 aurea, from which it differs only in the smaller, less warty and 

 paler spores. The spores of both are uninucleate.
