The Afy.voiiiyrrfrs of the I\fianii I'allcy, Ohio. 131 



1. LiCKA VARIABILIS, Sclirad. Plasinodiocarp not much 

 elongated, usually scattered, sometimes closer and confluent, 

 somewhat depressed, the surface uneven or a little roughened 

 and not shining, reddish-brown or blackish in color; the wall 

 a thin, firm pellucid membrane, covered by a dense outer layer 

 of thick brown or blackish scales, rupturing irregularly. 

 Spores in mass pale ochraceous, globose or oval, even or 

 nearly so, 13-16 mic. in diameter. 



Growing on old wood. Plasmodiocarp 1-1.5 mm. in length, 

 though sometimes 'confluent and longer. The wall is thick 

 and rough, not at all shining. It is evidently the species of 

 Schweinitz referred to by Fries under this name. 



2. LiCEA IviNDHKiMERi, Berk. vSporangia sessile, regular, 

 globose, gregarious, scattered or sometimes crowded, dark 

 bay in color, smooth and shining ; the wall a thin membrane 

 with a yellow-brown outer layer, opaque, rupturing irregu- 

 larly. Spores in mass bright bay, globose, minutely warted, 

 opaque, 5-6 mic. in diameter. 



Growing on herbaceous stems sent from Texas. Sporangia 

 about .4 mm. in diameter. The bright bay mass of spores 

 within will serve to distinguish the species. The thin brown 

 wall appears dark bay with the inclosed spores. 



3. lyiCEA BiFORis, Morgan, n. sp. Sporangia regular, com- 

 pressed, sessile on a narrow base, gregarious ; the wall thin, 

 firm, smooth, yellow-brown in color and nearly opaque, with 

 minute scattered granules on the inner surface, at maturity 

 opening along the upper edge into two equal parts, which 

 remain persistent by the base. Spores yellow-brown in mass, 

 globose or oval, even, 9-12 mic. in diameter. See Plate III, 

 Fig. I. 



Growing on the inside bark of Liriodendron. Sporangia 

 .25-. 40 mm. in length, shaped exactly like a bivalve shell and 

 opening in a similar manner. I have also received specimens 

 of this curious species from Prof. J. Dearness, London, Canada. 



4. LiCEA PUvSiLLA, Schrad. Sporangia regular, sessile, 

 hemispheric, the base depressed, gregarious, chestnut-brown, 

 shining; the wall thin, smooth, dark-colored and nearly 

 opaque, dehiscent at the apex into regular segments. Spores 

 in the mass blackish-brown, globose, even, 16-18 mic. in 

 diameter.
