164 Clavarias of the United States and Canada 



Chapel Hill as we have found it here only a few times. See under 

 C. apiculata for comparison with that species. 



Unfortunately there is nothing in Persoon's herbarium that 

 can be taken as the type of C. stricta. There are two sheets, 

 each of which is labelled with a question. One is from North 

 America ("Am. Bor."), and is the same as our C. stricta. The 

 other is from Europe (?), grew on earth, and is very doubtful. 

 Clavaria syringarum is well represented by what may be consid- 

 ered as the types. There are three plants collected under Syringa, 

 apparently by Persoon himself. They look exactly like C. stricta 

 and have the same spores, minutely rough, 3.5-4.8 x 6.3-9jj.. He 

 says the species is like C. stricta but "differs in growth on earth 

 under Syringa and in the spongy tuberous base," adding that it 

 has a taste of bitter almonds. The species is not mentioned by 

 Fries. 



Clavaria Icucotcphra is represented in the Curtis Herbarium by 

 the co-type from Hillsboro, N. C. (No. 6362). It is in very bad 

 condition, but the spores are exactly like those of C. stricta, 

 3.7-4A x 7.4-8.9[jl, ochraceous. There is also a plant at Kew under 

 the same type number and with the same appearance and spores, 

 3.8-5 x 7.5-9.3(1.. As the description is not at variance we are con- 

 sidering them the same. For some reason we have been unable to 

 find at Albany the type of C. densissima Pk. (Bull. Torr. Bot. Club 

 30: 98. 1903), but from the description and from the photo of the 

 type given by Burt (1. c, pi. 1, fig. 5) we see no reason to think 

 that it is anything but C. stricta. 



After a careful study of the co-type and authentic specimens of 

 Lachnocladium Michcneri B. & C. (Grevillea 1: 161. 1873), it is 

 impossible for us to say with certainty what the species really is. 

 Slides made by us by scraping the co-type ( Curtis Herbarium ; 

 Curtis No. 3534, Michener No. 479) show no spores ('?), but a 

 slide of this made by Farlow and now with it shows a large num- 

 ber of spores which are like those of C. stricta, slightly rough, 

 about 3-4 x 8-9[x. From slides of No. 3534 sent us by Dr. Farlow 

 and recently by Dr. Dodge we find that the hymenium is 38-50[j. 

 thick, deep yellow in section; basidia about 5.5[x thick; threads of 

 flesh 3-5. 5{jl thick and almost parallel in longitudinal sections. We 

 have not been able to find any spores like those of C. byssiscda
