The Mycologic Flora of the Miaiiii Valley, Ohio. 93 



Genus II. — Exidia, Fr. 



Funj;^! distended with jelly, tremulous, somewhat marginate, 

 papillose; a colored gelatinous stratum inclosing the sporophores, 

 the spicules of which are erumpent only at the apex. 



1. E. TRUNCATA, Fr. Soft, distended with jelly, disk truncate- 

 plane, glandular, black, shining, at length cavernous, punctate- 

 scabrous underneath; stipe very short; spores oblong, curved, 

 .012-. 014 mm. in length. 



On oak branches; common. An inch or less in height and 

 breadth. When dry very thin and intensely black, the glands 

 seldom apparent. 



2. E. GLANDULOSA, Bull. Effuscd, nearly plane, thick, undulate, 

 becoming black, spiculose with conic papilla, the underside ciner- 

 eous and somewhat tomentose; spores oblong, curved, .012-. 014 x 

 .005 mm. 



On old trunks and branches; very common. Extremely vari- 

 able in form and size; usually rather flattened and effused, some- 

 times for several inches. Sometimes becoming pallid on the 

 underside or inside of trunks away from the light The papillae 

 can be plainly seen with a common lens. In England it is called 

 "Witch's Butter." . 



Genus III. — NtEMATelia, Fr. 



Fungi consisting of a firm fleshy nucleus, inclosed by a thick 

 gelatinous stratum, fibrous- floccose within, the whole surface 

 covered by the sporophores. 



I. N. NUCLEATA, Schw. Effuscd, plane, somewhat gyrose and 

 undulate, white, then rufescent; the nucleus small, hard, white 

 spores oblong, curved, .010 mm. in length. 



On old trunks of Acer sacchariniim under the bark and erumpent 

 from the cracks: common. Effused sometimes for several inches, 

 folded and wrinkled. The gelatinous portion shrinks to a mere 

 membrane in drying, leaving the white grains, as large as mustard 

 seed, quite conspicuous. This seems different from the European 

 species which are termed " solid, not collapsing by dryness." 



Genus IV. — Dacrymyces, Nees. 



Fuiigi gelatinous, homogeneous, traversed within by septate 

 fibers; conidia moniliform-concatenate; sporophores at the apex of 

 the filaments, clavate, two-forked when fully grown ; spores 

 septate.
