This sing'iilar form occurs in compact tufts, sometimes very closely
appressed to the substratum, and is probably only a stunted condition of
the type. I t resembles the following species, but is distinguished by the
fibrillose and subfasciculate branches, and by the reaction of the medulla
with iodine. I t is never seen fertile.

Tbougli regarded as a variety of S. coralloides, this is distinguished by
the smaller and densely cæspitose tballus, the fastigiate efibrillose
branches, and the chemical reactions, though that with K i.s but little
visible in darker-coloured tballi. I t is usually pulvinate, and even when
best developed scarcely an inch in height, frequently glaucous towai’ds the
apices and lurid near the base of the brandies, occasionally reddish,
suffused on the surface with peroxide of iron. The apothecia are less
regularly globose than in the preceding species, the fertile branches being
more or less protruded. I t is most frequently sterile. The spermogones
are common, wdth spermatia ohlongo-cyliudrieal, very minute, 0,003 mm.
long, about 0,001 mm. thick.
Hab. On mossy (also nalied) rocks and boulders in upland, subalpine,

This tribe, as observed by Nylander (Syn.
i V, 174), is composed of genera differing considerably
in the thallus and apothecia. The
affinity of these genera, however, seems to be
with lach other in t h i s Series, rather than
with the Lecanorei or Lecideei, m which, toi
the most part, they have been variously placed
by authors.
