430 BRITISH FUNGI 



Craterellus 



Pileus deeply funnel-shaped, substance thin, pliant ; 113'menium 

 external, slighth' wrinkled. 



Superficially resembling some species of CivitJiaycUus, but dis- 

 tinguished by the absence of distinct gills. 



* Funnel-shaped ; hollow to the base of the stem. 



C. cornucopioides (PL XXXII, fig. i). — Very deeply funnel- 

 shaped, hollow to the base, thin, smoky black, minutely scaly 

 inside, edge turned over and wavy ; h\'menium grey, indistinctly 

 wrinkled, 2-4 in. high. 



On the ground in woods. Usually in dense clusters. Must be 

 carefully distinguished from Cantharellus cinereus, which has more 

 distinctly marked gills. In spite of its uninviting appearance, this 

 is one of the best of edible fungi. 



C. lutescens. — Deeply funnel-shaped, edge wavy, brown ; stem 

 hollow, smooth, yellow ; hymenium yellow, with branch- 

 ing, slightly raised veins. Stem 1-3 in. long, pileus 1-4 in. 

 across. 



On the ground in woods. Smell quite strong, resembling spirits 

 of wine. Cantharellus tubceformis is somewhat similar in appearance 

 to the present species, but has distinct gill lines. 



** Funnel-shaped ; stem stuffed. 



C. sinuosus. — Funnel-shaped, greyish brown, downy, edge wavy ; 

 stem pale yellow, stuffed, up to i in. high ; hymenium greyish, 

 with branching veins. 



Smell strong, musky. Pileus |-i in. high and broad. 



*** Irregularly top-shaped ; solid. 



C. clavatus. — Irregularly top-shaped, solid, pale dingy yellow ; 

 lu'menium almost e\'en, dingy purple. 



On the ground in woods. Pileus ii-2| in. across. 



EXOBASIDIUM 



Fungi parasitic on living plants, leaves more especially, which 

 become deformed. The whole of the vegetative portion of the 

 fungus is buried in the substance of the host, the fruit of the fungus 

 appearing on the surface of the leaf as a delicate bloom. 



E. vaccina. — Forming variously shaped fleshy patches on the 

 part attacked ; hymenium appearing on flesh-coloured patches on 

 the under-surface of the leaves, which become covered with a white 

 bloom. 



On living lea\'es of Vaccinimn myrtillus. Red or purple patches on 

 the upper-surface of the leaves indicate the presence of the fungus. 

 The parasite occurs on other species of Vacciniitm, also on species 

 of Andromeda and of Acrostaphylos, in various parts of Europe, and 

 may yet be found on other hosts in this country.
