Cladonia incrassata
e. incrassata is a suboceanic species distributed in Burope,
eastern parts of North Anerica and East Asia (Trass l-958,
Thomson L967, Ahti L977) . Closest to Finland it has been
found from South Scandinavia (Alnborn 1948, Santesson 1984)
and Estonia (Trass 1958 ) . This species rtas discovered as new
to Finland from a drained peat bog on the south coast by the
author Ahti in L979 (Kulckonen & Koponen L980, Rassi et al-.
1986). This is still the only known locality of g. incrassata
in Finland (Fig. 1) .
C. -incrassata grows often in large patch€sr which are easily
recogrnized by small (2-10 nm high), simple, areolatecorticate
podetia with red hlmenia. Basal sqfuamules are
small, yellowish-green above, pale below and usually
abundantly sorediate at the margins. When sterile g.
incrassata is easily overlooked or misidentified aq g.
digitata or g. cenotea, the two conmon species in similar
habitats. The chemistry of g. incrassata is, howev€Er
distinct: it contains usnic, didlmic and sqluamatic acids as
the major aromatic substances; rhodocladonic (hymenia),
condidlmic, subdialmic and barbatic acids are f ound as
accessory (Huovinen et al. 1989).
The habitat of c. incrassata in Finland is typical for the
