In Anglia ex ipsa planitie ultra 600" (2000 p. angl.) alt. 
ascendit, ubique pulchre fertilis ; locis planis (Castle Howard 
Park, Yorkshire ; Blackdown, Sussex ; etc.), semper fere Bra- 
chyodo trichode et Marsupella Funckit consociala; in montibus 
(Oxendale, 800 ped. ; Bow Fell, 2000 ped.; etc.), cum #. 
alpina , M. Funckii var., M. Stableri, M. crenulata Gottsche, 
cœterisque immixtam legit cl. STABLER. In monte Riesenge- 
 birge Germaniæ, inter specimina a cl. LiwpricuT lecla et sub 
n° 648 in G. ei Rab. Hep. Eur, distributa inveniuntur eliam 
M. adusta (Nees), M. olivacea et Brachyodus trichodes. FE 
M. adusta (Nees, fide Limpr.) stirps rigidior est, colore 
 magis olivaceo-badio quam adusto, Caulis est ramosior 
_ sæpiusque innovando-prolifer; folia densa ovalia oblongave 
_ (nec late ovata et subquadrata), fissura apicali solum ad 
+2 neque ad +— +, protracta, reti spissiore et opaco ; 
mi fertiles clavato-fusiformes; perianthium normaliter
