Plate 13 (p. 150) ' 



SepuUaria Longii. Upper figure, a vertical view of a cluster of apothecia 

 which make their appearance as a series of holes in the surface of the ground. 

 Lower figure, a section through such a cluster, giving some idea of the sub- 

 terranean habits of the species. At the left, a drawing of an ascus with spores 

 and a paraphysis. In the center, a portion of the mycelium which clothes 

 the outside of the apothecia and binds the soil together. 



Plate 14 (p. 160) 



Upper figure (1). Photograph of several apothecia of Patella albida, 

 made by Dr. F. E. Clements under the name of Lachnea chaetoloma. Upper 

 right-hand corner, sketch of a section through one of the apothecia, showing 

 general form of cup, also drawings of hairs from outside of apothecia. Lower 

 left-hand corner, drawing of an ascus with spores. 



Lower figure (2). Patella scutellata. Several apothecia on the bark 

 of a dead stump. Above, a sketch of a section through an apothecium. 

 Right, a drawing of a hair from outside of apothecium. Lefc, a drawing of 

 an ascus with spores and a paraphysis with its enlarged tip. 



Plate 15 (p. 176) 



Upper figure (1). Patella gregaria. Photograph of group of apothecia, 

 showing natural habitat under pine trees. Right, drawings of hairs from out- 

 side of apothecia. Left, drawing of a portion of an ascus with spores and a 

 paraphysis. 



Lower figure (2). Patella melaloma. Photograph of a group of apo- 

 thecia, showing natural habitat on charcoal. Right, drawing of portion of 

 an ascus with spores and a paraphysis. Left, cluster of club-shaped hairs 

 from outside of apothecia. 



Plate 16 (p. 180) 



Wynnea americana. Photograph of a sclerotium with a branched apo- 

 thecium. Right, drawing of a portion of an ascus with spores, showing the 

 longitudinal striations. Left, an isolated spore showing its unequal-sided 

 character. Above, sketch of the end of an ascus, showing the eccentricity of 

 the ascostome. 



Plate 17 (p. 184) 



Upper figure (1). Phillipsia gigantea. Three apothecia photographed 

 from dried specimens but about natural size. Also drawing of a portion of 

 an ascus with spores and a paraphysis. 



Central figure (2). Phillipsia domingensis. Several apothecia on a 

 dead stick. Spores apparently identical with those of the preceding. 



Lower figure (3). Cookeina Colensoi. Photograph of a number of 

 apothecia on moss-covered bark, made from dried specimens, which, however, 

 shrink little in drying. Left, drawing of a portion of an ascus with spores, 

 showing characteristic striations. Also the tip of a paraphysis.
