of thf eleuieat;, and tlie abundance of spores, and discrepancies 

 occur In tlie various descriptious published, as to the presence of 

 cystidia. Scbrenk mentioned " bhmt cvstidia " projecting but 



little over tlie surface of tlie lijmenium. Hedgcock and Long 

 describe for F. juniferiniis " cystidia few, nearly colourless, 

 100 X 20 [X, pointed, somewliat encrusted," and for F. Earlei no 

 cystidia, while Lloyd*, who examined part of the type specimen 

 of F. jmiijyeiiiii/s, states that no cystidia are present. In the 

 sjtecimens at Kew, the hymenium consists of young and mature 

 basiilia, the latter with 2 4 sterigmata, and between these are 

 occasional sterile bodies of varying size (Text-fig. h). These are 

 hyaline, very thin-walled, sniooth, cylindrical or somewhat 

 fusiform, projecting very little, 7 ,u wide ixnd up to 25 /x long. 

 Without an examination of the type material, it is not possible 

 to sav whether these may be von Schrenk's cystidia . No large 

 cystidia like those described by Hedgcock and Long are present. 

 The distribution of the fungus, as at present known, is peculiar. 

 In the Inited States F. juniperinus has been recorded from 

 Tennessee, Kentucky and Maryland, and F. Earlei from Texas, 

 New Mexico, Arizona and Colorado. Llovdf has recorded it from 

 Rus&ia. and has pointed out* that F. Dcmidoffii (Lev.) Sacc, 

 described on Junipems c.rceha from llussia, was probablv the 

 same species. Tlie new record from East Africa gives a third 

 widelv separated locality. The fungus does not as vet appear to 

 have been recorded from any other part of the world, and even 



«Iiere tonnd, the sporophoies seem to be as a rule but sparingly 

 produced. . i o .?
