BEY. J. M. CEOMBTE ON THE LICHENS OF 



rfi 



this is a proper species, as shown by the thalline reactions, viz. 



-K + (medulla fl. rubr.). Not previously distinguished by lichenists. 

 F. 43. Lichenoides platyphyllum, marginibus crinitis, p. 149, 



= Paemelia cobniculans, Nyl. in hb. Horsfield ? Of this there 

 is only a small sterile fragment (atypical) in hb. Dill., which 

 though agreeing in the Nylanderian reactions with this species, 

 K(CaCl)+ reddish, is necessarily somewhat doubtful. Eeferred 

 by Fries to P. hottentotta. 



F. 44. Lichenoides hypotropa f. parmata, Nyl. in lift. Spores 

 0009-0-011 millim. long, 0-007-0-008 millim. thick. The speci- 

 men in hb. Dill. i 3 evidently a portion of the original one in hb. 

 Buddie. Hitherto not distinguished by authors from P. pi 

 rata, to which it has been referred. 



F. 45. Lichenoides hispidum majus et rigidius, scutellis nigris, 

 p. 150. A = Phtscia ciliaeis (L.). Fertile. B, C=f. mela- 

 nosticta, Ach. With spermogones. D=f. agbiopa, Ach., a 

 young state. Some of the apothecia in the type have, as will be 

 seen from the figure, the margin proliferous and the laciniolae 

 fimbriated (f. actinota, Ach.). 



F. 46. Lichenoides hispidum minus et tenerius, scutellis nisris , 

 p. 152. A, B = Phtscia leptalea, Ach. (A =young and sterile 

 state). C, E = Putscia tenella {Scop.). D = Ph. leptalea 

 saxicole, with thallus and apothecia less evolute. Figs. C, E, have 

 not sufficiently been distinguished from the others. 



F. 47. Lichenoides quod Lichen pulraonarius minimus, arbori- 

 bus innascens, ad margines radicatus, superne cinereo-fuscus, in- 

 terne anthracinus, receptaculis florum fuscis, Mich., p. 15_, 

 Phtscia obscuba, var. chloantha (Ach.). Of this there is no 

 specimen in hb. Dill. Identified by Fries in Index Dill.' 



F^ 49. Lichenoides ceratophyllon obtusius et minus ramosum, 

 p. 151. A, B= Paemelia phtsodes (L.), of which A is fertile. 

 C = P. phtsodes, var. labbosa, Ach. Sterile. D = Paemelia 

 centbifuga (L.). Of this there is only a small and not very cha- 

 racteristic specimen, though fertile. Hitherto not determined. 



Division II. Species with the scutellse sessile and closely 



adnascent to the leaves. 

 Subdivision I. Leaves narrower or broader, scutelke (with a 



few exceptions) unicolorous. 

 Tab. XXI., Dill. Hist. Muse. 

 F. 50. Lichenoides angustifolium planum, crinibus nigris, p. 156,
