2. Phillipsia gigantea Seaver, sp. nov. (Plate 17, fig. 1.) 

 Apothecia occurring singly or in clusters of 3 or 4 each with 



their bases more or less fused together, the individual apothecia 

 infundibuliform, tapering below into a rather thick, stem-like 

 base, elongated on one side or nearly symmetrical, the margin 

 often more or less lobed, reaching a diameter of 4 6 cm. and a 

 depth of 3-4 cm., externally nearly white or with a pinkish 

 tinge which is somewhat darker below, delicately tomentose, 

 the substance tough so that the apothecia maintain their form 

 fairly well in drying; hymenium bright-purple or purplish-red, 

 splitting into numerous vein-like markings when dry; stem thick, 

 often reaching a length of 1-2 cm. but not clearly defined; asci 

 cylindric above, rounded at the apex, with the operculum 

 opening a little to one side of the center, gradually tapering 

 below into a stem-like base, reaching a length of 500 ^ and a 

 diameter of 17-18 m at the broadest point, 8-spored, but often 

 with only four or five of the spores developed; spores 1-seriate, 

 ellipsoid, unequal-sided with the ends bluntly attenuated, con- 

 taining two oil-drops which often merge into one, longitudinally 

 marked with light and dark bands, 12-14 X 25-27 m, hyaline; 

 paraphyses very slender, reaching a diameter of 2-3 n at their 

 apices. 



On decaying wood of some monocotyledon. 



Type locality: Castleton Gardens, Jamaica.

(Frontispiece.) 



Apothecia orbicular or nearly so, subsessile, reaching a

 brick-reddish, the substance thin (about 1-2 mm., not thick or 

 corky as in other species) ; asci cylindric or subcylindric, reaching 

 a length of 300 /x and a diameter of 14 fx, 8-spored ; spores ellipsoid,
