266 FUNGI. 



whilst little circular violet-brown patches, zoned exter- 

 nally, and turning crimson when wounded, present plants 

 of the Bloody Stereum (S. sanguinolentum, Plate 

 XVIII., fig. 19, right corner of the plate). 



The Hymenochsete group is characterised by stiff 



bristles. The rusty species (H. rubiginosa, Plate XVIII, 



fig. 10) grows on posts and pales, is of a rich burnt 



siena colour, and looks like a folded piece of worsted 



velvet. 



In the Corticium group the Hymenium is swelled 

 when moist, and often fringed with tiny hairs around the 

 edge. The Purple Corticium (C. cseYxileum.,PlateXVIII, 

 fig. 9) looks like a morsel of rich blue velvet when moist, 

 but it becomes duller when dry. The Oak Corticium 

 (C. quercinuni) is brownish lilac, and is very common 

 on dead or aged oak branches, the patch measuring from 

 one to three inches in length. The Elder Corticium, 

 (C. sambuci) is Avhite and very thin, it grows on Elder 

 stumps, cracking with the inequalities of the bark. All 

 these species are very common, the localities where we 

 have found them are too numerous to mention. 



A group of minute and elegant fungi form the 

 Cyphella group, they are cup shaped, and often pendulous, 

 somewhat resembling Cantherellse in their veined 

 Hymenium. Near Eichmond in Yorkshire I found the 

 little moss Cyphella (C. Muscigena, Plate XVIII, fig. 

 3) growing upon one of the large Feather mosses ; this 

 is the only species which we have any of us found. 



We now come to the fifth order, that of Clavarise, or 

 Club-fungi, characterised by having the Hymenium 

 upon the Club, up to its very summit. The true Clavariae
