stem sparingly beset with radicles, sparingly branched, branches 

 irregularly pinnate ; leaves patent, secund, narrowly elongate, 

 lanceolate, not narrowed to the base, narrowly acuminate ; nerve 

 thin, extending to the middle of the leaf; the margin plane, 

 areolae narrowly hexagonal-linear, broader and shorter at the 

 extreme base, the primordial utricle not conspicuous ; inflorescence 

 monoecious ; parichajtial leaves erecto-patent, leaves few, pale, 

 suddenly acuminate, entire, nerveless ; capsule oval, yellowish, 

 arcuate, constricted below the mouth when dry and after the lid 

 has fallen ; annulus (?) ; teeth of the peristome narrowly lanceo- 

 late, densely articulated, orange coloured at the base, paler above, 

 teeth nearly entire, ciliae binate or ternate nodulose. 



Observations. — From Rhyncostegium teneUum, which it closely re- 

 sembles in appearance, it is distinguished by its delicate habit, by 

 the nerve not extending beyond the middle of the leaf, and by the 

 rough fruit stalk; from Rhi/nch. curvisetum (Brid.), Lindberg {Rh. 

 Teesdalii, Br. eur. et Schpr. Syn. p. pte. ; Hijp. rigiduluin, Bruch.,) 

 by the base of the leaf not being narrowed, and of a longer lancet- 

 shape, by the accuminate apex, by the thinner nerve, and by the 

 areolation of the leaves. 



Hab. — Iglesias, in Sardinia (Fr. Mull.), Sierra de Palma, near 

 Algesiras, in Spain (R. Fritze). E. M. H. 



REVISION OF GEOGLOSSUM. 

 £i/ M. C. Cooke 



The species of Geoglossum enumerated in the " Handbook," at 

 pp. 662, are imperfectly described in so far as the fruit is con- 

 cerned. The following revision of these characters will therefore 

 be noted by those who are in possession of that work, 



1856. Geoglossum viride. P.— Asci cylindrico clavate ; sporidia 

 narrowly elliptical, or somewhat lanceolate, obtuse at the ends, 

 hyaline, simple (-03 X "01 m.m.) ; paraphyses linear, scarcely 

 thickened at the tips. 



1957. Geoglossum olivaceum. P.— Asci cylindrico-clavate ; spo- 

 , ridia narrowly elliptical, obtuse at the ends, hyaline, simple (-025 



X '008 m.m.) ; paraphyses linear, scarcely incrassated. 



1958. Geoglossum glutinosum. P. — Asci cylindrico-clavate ; spo- 

 ridia cylindrical, straight or curved, 3-septate, brown (-08 m.m. 

 long) ; paraphyses filiform, with pyriform tips. 



1959. Geoglossum viscosum. P. — Asci cylindrico-clavate ; spo- 

 ridia cylindrical, straight or slightly curved, 3-septate, brown 

 (•09--01 m.m. long) ; paraphyses filiform, globose at the tips, not 

 septate.
