fimbriate. Hymeniuni on the even spots and sides of the branches, 

 papillose. 



Growing on mosses, grasses, etc., and running over leaves. 

 There is no constant form ; it is to be recognized by its whitish color 

 and the awl-shaped or fringed branches and lobes. 



13. T. SPICULOS.'^, Fr. Effused, byssine then fleshy, incrust- 

 ing, brownish-purple; the border spiculose-branched ; the apices 

 penicillate, whitish. 



Ascending the stems of herbs, 'in humid places; rare. Of a 

 brownish color, effused, throwing out here and there radiating 

 subulate spicules. 



14. T. SEBACEA, Pers. Effused, fleshy-waxy, hardening, 

 incrusting, tuberculose or stalactitious, whitish, with a similar 

 border. Hymenium collapsing, flocculose-pruinose. 



Incrusting various substances ; common. Various in form, 

 white, the border not fringed or penicillate. 



Genus III. — Lachnocladium, Lev. 



Pileus coriaceous, tough, repeatedly branched; the branches 

 slender or filiform, tomentose. Hymenium amj)higenous. 



Fungi slender and much branched, epixylous or terrestrial. 



1. L. SEMiVESiiTUM, B. & C. Coriaceous, pale or sordid 

 brown, tomentose. Pileus much branched from a slender s'ipe of 

 variable length, expanded at the angles; the branches filiform, 

 straight, somewhat fasciculate, glabrous at the lips and jjaler in 

 color. 



On rotten leaves and sticks in the ground ; rare. Pileus i -2^ 

 inches in height, more or less flattened or expanded at the points of 

 branching, the branches straight and slender, pubescent or finely 

 tomentose, glabrate with age. 



2. L. isncHENERi, B. &C. Coriaceous, pale brown, densely 

 tomentose. Pileus arising from a dense tomentum, repeatedly 

 irregularly forked and branched ; the branches very slender and 

 flexuous, with paler tips. 



On old leaves and sticks; common. Pileus ^-i inch in length, 

 the branches very delicate, filiform and flexuous. The tomentum 

 at the base is sometimes an " orbicular villous patch," sometimes 

 an effused patch of mycelium of considerable extent, out of which 

 arise several stems ; it is often distributed in i)atches over the stem 

 and branches even to the extremities. I think L. subsiiiiilc, Berk., 

 can hardly be separated from this species.
