THE FRUCTIFICATION

septate hypha, proceeding as an assurgent branch from the 



mycelium. In its upper portion it produces, at intervals, 



branches one, two, or three, at the same level, and these again 



produce branchlets in whorls of three. Each branchlet is 



surmounted by an ovate conidium, or sometimes two or even 



three together. This, therefore, is a mould, 



with somewhat of a dendroid habit, with 



verticellate branches and . branchlets pro- 

 ducing terminal naked conidia. Take as 



another example the common mould, Peni- 



cillium glaucum, or any other Penicillium 



(Fig. 31): the erect carpophore divides at the 



apex into a cluster of short branches, and 



each branch is terminated, not by a single 



conidium, but a series of conidia, attached 



end to end in a chain, each conidium falling 



away successively as it attains maturity. 



In other genera the carpophore is very 



short and unbranched, either terminating in 



a single spore or in a chain of spores, but 



the principle is the same — that of naked conidia borne direct 



by the carpophore, without receptacle. 



We can only recognise in the Uredines 

 a modification of the same principle, which 

 is most strongly manifest in Phragmidium 

 (Fig. 32). The teleutospores consist of an 

 elongated simple carpophore, surmounted by 

 a multiseptate spore-body, and there is no 

 receptacle. It is similarly manifest in 

 Uromyces and Puccinia, for the teleutospores 

 have a distinct pedicel, which bears the 

 fruit and is the carpophore. In some 

 other genera it is less manifest, whilst in 

 Aeoidium and Raestelia the distinct recep- 

 tacle is of the cup -shaped series, ope a 

 above. 



In all the instances given in this 



chapter we have denominated the bearer of the fructification 



by the general term of " carpophore." This is by no means 



Conidiophore 

 of Penicillium.
