Cc/nin'fi ///'(isrc/is prefers a sandy soil ; it grows in low depressions in 

 the ground which are filled with water after rain and which after some 

 time dry up. Also on alpine marshes. At suitable places it covers con- 

 siderable areas, growing in dense clusters. 



It is decidedly an alpine plant, being found much more frequently and 

 better developed c)n the mountains than in the lowlands. It is common on 

 the mountains in our whole country. But it also descends to lower alti- 

 tudes, even in Southern Norway, e. g. Abildsjo near Kristiania. Not recor- 

 ded from the west and south coast. 



Apothecia are not rare. 



Se\eral varieties have been proposed of this species.' Want of suffi- 

 cient material for comparison prevented me from accurately determining 

 our specimens. So riiuch can, however, safely be stated that by far the 

 greater part of the Norwegian material belongs to var. Delisei (Borr.) Wain. 

 There was nothing comparable to var. dilatata Wain., nor to var. rhizo- 

 pliora Wain. But several specimens from Northern Norway approach very 

 much to var. fastigiata (Del.) Wain, and can probably be referred to this 

 variety. Nylander as well as Wainio emphasizes its likeness \x\i\\ C. crispa, 

 our only specimen (Finnish, leg. et det. Lang) has broad, rounded, litde 

 incise laciniae, and bears ä great resemblance to a platvna-ïovïn of C. islandica. 



In very shady positions it acquires a paler colour, occasionally also a 

 very narrowly laciniate thallus, even resembling that of a Cladonia (e. g. 

 C. sqiimnosa). I have found such specimens on the bottom of the 'Jutul- 

 hugget, a deep canon-like formation in Østerdalen, Eastern Norway. They 

 almost look like a distinct variety.

 omnino incoloratus vel parte exteriore p. p. obscuratus, hyphis perpendi- 

 cularibus, septatis, v^alde pachydermaticis, luniinibus fere exclusis, formatus, 

 cortex infrahypothecialis 50 — 60 \x altus, hyphis minus distincte perpendi- 

 cularibus et minus pachydermaticis formatus. HN'phae medulläres 5 — 6 [x 

 crassae, ramosae, non adspersae. Gonidia strato crasso continue sub cortice 

 infrahypotheciali inclusa, in medulla praeterea fere desunt. Hypothecium

 nium angustum, 50 — 55 \x altum, non inspersum, superne flavo-fuscescens,
