IV. Scores smooth, globose, brownish olive, olive, or various shades 



of yellow. 



30. L. elatum Mass., nov. sp. — Stipitate, peridium globose, sub- 

 umbonate, thin, with a few evanescent furfuraceous squamules, lacunose 

 below ; stem elongated, equal, cellular, lacunose. Capillitium dense, 

 persistent, continuous with the copious cellular base, threads lax, thinner 

 than diameter of spores, sparingly branched, firm ; spores ferruginous- 

 olive, globose, smooth, shortly pedicellate, 5 fju diam. Plate XIII. figs. 

 13-15. 



In Herb. Berk, placed with L. saccatum, probably without examina- 

 tion. Allied to L. perlatum. 



Peridium 2 in. across, stem 6 in. long, 2/3 in. thick, reddish ochre 

 when dry. On the ground. New England. 



31. L. 'perlatum, Pers. Syn., p. 145. — Peridium variable, subglobose 

 with an elongated stem, subglobose or depressed and nearly sessile, um- 

 bonate, ochraceous or dirty brown, at first covered with spinose warts, 

 which are smaller downwards, disappearing with age, mouth small, torn, 

 at apex of umbo. Capillitium continuous with the convex cellular 

 sterile base and forming a columella, threads rarely branched, about 

 equal in thickness to diameter of spores, flexuous; spores olivaceous, 

 globose, smooth, 4 ^ diam. — L. perlatum, Barla, pi. 46, f. 8. L. 

 gemmatum, Fr. S. M., iii. 36. Sverig. Svamp., tab. Ixxiii. Fl. Dan., 

 MCXL. Krombh., t. 30, f. 6. Cke. Hdbk., 1088 (including L. gemma- 

 tum). Palist, Crypt. FL, t. 23. L. constelJatum, Sturm, t. 7 ? L. 

 lacunosum,.'^vXi., t. 52 ? L. hirtum, Bull., t. 340 ? L. perlatum, Vitt. 

 Mon., 194. Allied to L. gemmatum, but readily distinguished by the 

 umbonate mouth and distinct columella. The peridium is often plicate 

 below, and the stem more or less lacunose. Often occurs in pairs from 

 the same base. 



In woods, especially of oak. Summer and autumn. Europe. 



32. L gemmatum, Batsch, Elench., p. 147. — Stipitate, subglobose, 

 depressed above, or lens shaped, obtuse, with prominent spinose warts of 

 various sizes, which eventually fall off, leaving the surface smooth and 

 shining, dehiscing by a small opening ; stem stout, tapering downwards. 

 Capillitium continuous with the well-developed cellular sterile base, 

 threads lax, rarely branching, axils acute, tapering; spores olivaceous 

 umber, globose, smooth, 4 yu. diam. — L. gemmatum, Hussey, i. pi. 54. 

 Sci. Gossip, Dec. 1866. Eng. Flor., 304 (including L. perlatum). 

 Karst. Myc. Fenn., iii. 361 (including L. perlatum). Cke. Hdbk., 

 1088 (including L. perlatum). L. gemmatum /3 perlatum, Fr. y. M., 

 iii. 37. Utraria gemmata. Quel. Champ. Jur. et Vosg., p. 358. 



Peridium 1-2 in. diam. Amongst grass, &c., in woods and shady 

 places. 



There is a form in Herb. Berk, from Sikkim Himalayas with the 

 peridium fusiform, in some of the specimens elongated and not much 

 thicker than the stem, but it agrees with the present species in the 

 capillitium and spores, and is connected with the typical form by 

 transitional states from various countries.
