Apotheciaare small, spherical, terminal or lateral, sometimes are solitary 
but oftener are crowded together at the end of the podetium ; the disk is a 
dark, reddish brown, with no margin. 
Found on rocks in the mountains of New England as well as those of the 
Stereocaulon paschale (L.) Fr. Fig. i. 
Primary thallus, as in 5 . coralloides , 
usually wanting. Podetia long, rather lax 
and slender, much branched and covered 
with squamulous, crenate, dark gray 
granules which are smaller than in S. 
coralloides. Along the podetia are fre- 
quently bare spots showing the broken 
cortical layer and the white medullary tis- 
sue inside. 
Apothecia are at or near the apices of 
the podetia: they are rather small, very 
numerous with a flat, dark brown disk. 
S. paschale is found on rocks and is a very handsome species. It grows 
in round, thick mats; the podetia are decumbent when dry, almost erect 
when moist. It is sometimes very abundant on rocks in cleared land on 
mountain slopes; is said to grow abundantly on volcanic lava. 
Stereocaulon tomentosum (Fr.) Th. Fr. Primary thallus distinct and 
granular. Podetia large, solitary or loosely caespitose, covered with 
crowded gray granules which are very tomentose. At the base the podetia 
are bare, especially on the under side. 
Apothecia very small, terminal or lateral, disk dark brown, convex, 
becoming subglobose. 
Found on the earth in mountainous regions, 
S. tomentosum (Fr.) Th. Fr. var. alpinum Th. Fr. This is a small 
alpine form of S. tomentosum. The thallus is small, the podetia compressed 
and erect, not very tomentose, the granules are light gray, almost white 
and very powdery. 
Apothecia usually terminal and rather large, with a dark reddish brown, 
convex disk. 
Found on the ground or on boulders in alpine or sub-alpine districts. 
Stereocaulon condensatum Hoffm. Fig. 
2. Primary thallus very small and warty, 
podetia very short, prostrate, with short 
branches which are covered with very 
crowded, powdery granules ; these are from 
light to dark gray in color. The primary 
thallus often forms a granulose crust and the 
podetia almost disappear. 
Apothecia terminal and in a close cluster, 
the disk convex, dark, reddish brown. 
Found on the earth in upland districts, 
more frequently on or near the sea coast.
