SPORE-DISCHARGE IN THE GENUS CALOCERA 191 



classification given at the beginning of this Chapter, is included 

 in the Tremellineae. The fruit-bodies of Calocera resemble those 

 of Clavaria very closely in form ; and there are few beginners in 

 mycology who, on first finding such a species as Calocera viscosa, 

 do not mistake it for a Clavaria. Unbranched species of Calocera, 

 e.g. C. cornea, correspond to unbranched Clavariae, and branched

species, e.g. C. viscosa, to branched Clavariae. Calocera differs 

 from Clavaria, however, in that it is subgelatinous, becomes horny 

 on drying, revives in wet weather after having been dried, and in 

 that its basidia possess a distinctive form. The basidium of Calo- 

 cera, instead of being clavate and bearing four slender sterigmata 

 and as many spores, is cylindrical and bifurcated into two long and 

 thick arms or sterigmata which penetrate the gelatinous matrix, 

 just as in a Tremella, and bear aerially one spore each. 



The fruit-bodies of Calocera cornea (Fig. 68) are often found 

 growing out from the sides and tops of old logs, tree stumps, etc. 

 They are slenderly clavate in form and usually unbranched. Just
