ELAPHOMY'CES, Nees.— A genus of 

 Tuberacei (Ascomjcetous Fungi) consist- 

 ing of subterraneous truffle-like plants, with 

 a "vvarty or hairy rind, not bursting sponta- 

 neously, but divided into little chambers 

 internally by intersecting plates of sporife- 

 rous tissue. The spores are formed in sacs 

 (asci) {tig. 185), from four to eight in each, 

 ai'ising fi-om branched anastomosing fila- 

 ments {capiUitium). Three species are 

 found in this country : — E, anthracinus, 

 Vitt., in clayey ground; E. granulatus, 

 growing in heathy groimd ; and E. muri- 

 catus, Fr. {E. variegatus, Vitt., Tulasne), 

 attached to the rootlets of beeches. L. and 

 C. Tulasne have carefully analyzed this 

 genus.

ELASTIC LIGAMENTS.— These are 



yellowish strong bands, consisting of elastic 

 or yellow fibrous tissue, with a small quan- 

 tity of connective tissue. They are met with 

 connecting the arches of the vertebrae (liga- 



menta subflava), in the stylo-hyoid and in- 

 ternal lateral ligaments of the jaw, and the

ligamentum nuchae, or 'paxy-waxy,' of ani- 

 mals. They contain but few vessels, and 

 no nerves. The elastic fibres (fig. 187) are 

 from 1-7500 to 1-3500" in breadth, slightly 

 flattened (fig. 186), mixed with still finer 

 and some coarser elastic fibres, formino; a 

 dense network, taking a general direction 

 parallel to the long axis of the spine. Be- 

 tween these fibres are loose undulating
