tenuated towards their extremities, and about six in a 

 whorl. On the decaying stems of herbaceous plants, in 

 white mouldy patches. (PI. V., fig. 10.) 



374. FRUIT MOULD \Mticor mucedo). Common on 

 decaying fruit. The structure is similar to the next, ex- 

 cept that the threads are not branched. Ultimately the 

 mould turns blackish. 



375. BRANCHED MOULD (Mucor ramosus). The 

 threads in this mould bear at theii tips sporangia, or spore- 

 cells, which contain numerous sporidia ; the cells at length 

 burst, and the spores are set free. It is common on de- 

 caying fungi, and the threads are very much branched at 

 their extremities. 



376. DOG'S MOULD (Mucor caninus) is common in 

 damp weather on the dung of cats and dogs. The threads 

 are unb ranched, and the heads are at first white, be- 

 coming yellowish or rusty brown. 



377. GOLDEN MOULD (Sepedoniuin chrysospermutii). 

 The interior of rotting Boleti, when broken, are often seen 

 to have become of a bright yellow colour, from the 

 globose rough spores which occupy the whole substance 

 of the pileus of the Boletus. It is very common in winter. 

 (PI. V., fig. 44.) 



378. MAPLE BLIGHT ( Unanula btcornis). This singular 

 fungus covers the leaves so that they appear as if white- 

 washed. On the entangled threads, globose dark-coloured 

 conceptacles are produced, each surrounded by numerous 

 appendages or processes which are forked and recurved. 

 (PL V, fig. 39.) 



379. HAZEL BLIGHT (Phyllactinia guttata). This has 

 something of the character of the preceding; but the 

 mycelium is less profuse, so that it is sometimes scarcely 

 to be distinguished by the naked eye. The appendages 

 of the conceptacles are few, straight, and awl-shaped. 



380. BERBERRY BLIGHT (Microsphceria Berberidis}. 

 On leaves of the berberry. The conceptacles are small, 

 and surrounded by from five to ten appendages, which 

 are divided and subdivided at their apices in a forked 

 manner. (PI. V., fig. 42.)
