corticula, indiscretum, minute papillosum, pilosum et coloratum. Hymenium 

 quod fungi cavitatis paries est, albidum, ex fibris seu filamentis constans long- 

 issime linearibus, subdiscretis aut vix cohserentibus, parallele e receptaculo 

 prodeuntibus, inaequalibus sterilibusque (paraphysibus), nee non et utriculis 

 immistis paucioribus crassis longe cylindricis obtusis, in filum longum deorsum 

 desinentibus, ascis soil, seu thecis octosporis. Sporae uniseriatae, sphaericae 

 aut ellipticae, leves, pellucidse, dilute coloratae; nucleo oleoso, tandem 

 homogeneo nee partito.

Minute, reddish brown, subrotund, cavernous without exterior opening, 

 minutely and closely papillose; gleba compact, white; asci cylindrical, obtuse, 

 175 /i in length, 8-spored; spores globose, hyaline and unequally papillose, 

 25 /i in diam . 



Type, No. 98, Harkness Coll. 



Under Libocedrus., Alta, Placer County, Calif., May.

Genea Vitt., Monog. Tub., p. 27. 



Common integument warty, with an aperture at the apex. Hymenium 

 waved and sinuated, but not forming an intricate mass. Asci cylindrical. 

 Sporidia globose [or subglobose.] (Berk. Outlines Brit. Fung., p. 378.) 



56. Genea compacta, sp. no v. 



Plate XLIII, Figs. loa-io^. 



Minute, i cm. in diam., irregularly stellate, color light brown, verrucose, dis- 

 tinct base with branching filaments; gleba white, irregularly cavernous; asci 

 cylindrical, stipitate, 270^1 in length, 8-spored; spores ellipsoidal, verrucose, 

 25 x 18 /x. The fungus is exceedingly rare. The filaments composing the 

 paraphyses are septate, extremely delicate, and of unusual length and wavy. 



Type, No. 86, Harkness Coll. 



Found in the forest, Mt. Tamalpais, Marin County, 

 Calif., April. 



The verrucosity consists in the surface of the spore being 

 covered with small, round, knob-like projections, about 

 sixteen being found in the circumference.
