 has been considered a variety, but in 2071 the spores are smooth, while in 

 this they are minutely warted or spiny. 



2069. L. laeunosum Bull, (from the pits or depressions on the stem ; 



lacuna, a hole or cavity) a. 



Pe. subglobose, passing into a long stout stem, covered with small

 with small lacunae. Cap. and Spores olive-brown. 



Woods. Autumn, if X 4J in. 



2070. L. pyriforme Schaeff. (from its pear-like shape ; pyrus, a pear, 

 forma, shape) a b c. Subumbonate. 



Pe. thin, flaccid, at first covered with minute pointed warts, 



brown, stoma small, torn, base sometimes forming a Col., 



slightly cellular. Cap. and Spores olive. 



Commonly ccespitose, often held together by coarse strands of white Myc. 

 On the ground in fields and woods, on rotten stumps and branches, 

 pollards, oak. July-Nov. if x 2\ in. Col. not a permanent character. 



2071. L. perlatum Pers. (from the great width of the peridium in 



comparison with the slender stem ; per/atus, very wide) a b c . 

 Pe. subglobose or flattened, often passing into a somewhat 

 slender stem, umbonate, often plicate below, at first covered 

 with stout obtuse short spines, base sometimes forming a Col., 

 pale brownish-salmon, stoma small. St. slightly spongy- 

 cellular and in section convex above. Cap. and Spores 

 olivaceous. 



Woods, thickets, amongst trees, firs. Sept. -Nov. i\ x 5 in. Col. not a 

 permanent character. Sometimes made a var. of 2068, or 2068 is some- 

 times made a var. of this, but the spores are different. 



2072. L. molle Pers. (from its softness or soft scurfy surface ; mollis, 



soft). 



Turbinate, base broad, abrupt. Pe. papyraceous, at first furfura- 



ceous, collapsing, umber to olive, stoma small, irregular. Cap. 



collapsing, ochreous-olive. Sterile base well developed, slightly 



spongy-cellular. 



On the ground, woods, oak. if x 2^ in. Differing from 2068 in the 

 smooth spores. 



2072a. L. erueiatum Rost. (from the somewhat cross-shaped spines 

 of the cortex) a. 

 Pe. subglobose to broadly pyriform, narrowed below into a short 

 stout sterile stem-like base, ij-ij in. high by f-ij in. broad. 

 Cor. whitish, formed of groups of minute, more or less 

 pyramidal spines, breaking away in large flakes and exposing 

 the inner yellowish-brown minutely granulated peridium ; 

 dehiscence by a small irregularly torn apical stoma. Gl. 

 umber. Spores globose, smooth, almost hyaline, 5-6 /x in diam. ;
