paler towards the base, minutely tomentose, debiscing by a small dentate 

 mouth. Threads of capillitium flaccid, sterile stratum obsolete ; spores 

 pale reddish ochre, globose, echinulate, 4 /j, diam. 



Peridium 1 in. or more m diam. On rotten trunks- Cuba. 



78. L. Vittadinii Mass., nov. sp. — Globose, sessile ; peridium rigid, 

 woolly, mouth small, irregular, rufous when dry. Capillitium dense, 

 threads tirm, flexuous, about equal in thickness to diameter of spores, 

 sterile base obsolete. Spores brownish olive, globose, strongly echinulate, 

 4 fi diam. 



Sent by Yittadini to the Eev. M. J. Berkeley as L. defossum, along 

 with auother specimen which was the true L. defossum, as described 

 by Vittadini. A striking illustration of the worthlessness of external 

 characters alone in the discrimination of species. 



About 2/3 in. across. Italy. 



79. L. suhincarnatum, Peck, N.Y. Nat. Hist. Mus. Bot. Eeport 

 (24tli). — Peridium globose, rarely either depressed or obovate, gregarious 

 or caespitose, sessile, with but little cellular tissue at the base, covered with 

 minute nearly uniform pyramidal or sabspinulose at length deciduous 

 warts, pinkish brown, the denuded peridium whitish or cinereous, minutely 

 reticulate-pitted; capillitium and spores greenish yellow, then dingy, 

 olivaceous, columella present ; spores miimtely rough, 0*000 16-0*000 18 

 in. in diameter (= about 4-5 /a). 



From 1/2 to 1 in. broad. Sometimes has white fibrous roots like 

 L. pijriforme. 



Prostrate trunks, old stumps, &c., in woods. Common. Aug.-Oct. 

 United States. 



III. Spores globose, smooth, purple, lilac, or various shades of brown. 



80. L. pusio, B. & C, Cuban Fungi, No. 503, Journ. Linn. Soc, 

 X. 844. — Globose, smooth, thick, corrugated when dry, mycelium forming 

 a dense fibrous rooting mass. Capillitium dense, threads often two to 

 three times thicker than diameter of spores, firm, tapering, sterile base 

 obsolete ; s]5ores purple-umber, globose, smooth, from 2-3 fM diam. 



About 1/3 in. diam. On rotten wood, into which the mycelium 

 penetrates deeply. Cuba. 



81. L. Astrocanji, Berk. & Cke., Brazil Fungi, Journ. Linn. Soc, 

 XV. 393. — Sessile, globose, attached by a broad base, brown, minutely 

 granulate, dehiscing by a small subrotund mouth. Threads of capil- 

 litium slender, collapsing, sterile base almost obsolete ; spores dirty 

 ochre, eventually assuming a hlac tinge, smooth, globose, 3 fx diam. 



From 1/4—1/2 in. across. On petioles of Astrocarijum. Brazil. 



82. L. Emodense, Berk., in Hook. Journ., vi. 172 (1854).— Ovate, 

 passing into a very short stem, peridium minutely furfuraceo-squamulose, 

 rufous, dehiscing by a large irregularly torn mouth ; root of long white 

 branched fibres. Threads of capillitium branched, axils acute, varying 

 in thickness, flexuous, basal barren stratum obsolete; spores brownish 

 umber, globose, smooth, 4 /i diam. 



About 1 in. high, 3/4 in. thick. On the ground, sometimes growing 

 in clusters. Sikkim Himalayas (9-10,000 ft.), E. Nepaul (9000 ft.).
