398 REV. J. M. CR0MBIE ON AUSTRALIAN LICHENS. 



On rocks, Table Mt., sterile. Coll. Br. no, 525 5, 8. n. fifoy- 



phophorus ? 



JNylander (I. c.) observes that the systematic place of this pe- 

 culiar plant is very doubtful, on account of only young apo- 

 thecia being present and no spermogones being visible in the 

 specimen seen by him from the Murray River, Australia, s. n. 

 Parmelia semiviridis, Mull. 



5. PSOROMA nYPNORUM (Ilffill.). 



On the sides of rocks, Table Mt. A very fragmentary speci- 

 men with only three apothecia present ; but it seems quite iden- 

 tical with the European plant. Coll. Br. no. 554, s. n. Lichen 

 hypnorum. 



G. PSOROMA SPHINCTRINUM (Mtlt.). 



On trunks and branches of trees, Derwent River : fertile. 

 Coll. Br. no. 533 a, s. n. Lichen dendrosmce similis. 



Var. leprolema, Nyh y L. Campbell, p. 3. 

 Along with the preceding (b), fertile. 



7. Psoroma asperellum (Hmp.) y Nyl. " Thallus squamulis 

 albido-pallescentibus minutis constans crenatis subdispersis (vel 

 passim imbricatis) ; apothecia pallido-rufescentia (latit. circa 1 

 millim.), margine thallino fere crenato (vel subintegro) cincta; 

 sporje longit. 0012-0016 millim., crassit. 0'008-0'009 millim. 

 G-elatina hymenia iodo vinose fulvo-rubescens (pnecedente caeru- 

 lescentia Isevi)." — Nyl. Syn. t. ii. p. 24. 



On the bark of trees, sides of Table Mt. Coll. Br. no. 547, 

 8. n. Lichen ascendens. Recorded also from the Cape of Good 

 Hope. 



8. Psoroma soccatum (H. Br.)> sp. n. Thallus pallidus vel 

 subflavido-albidus (K — ), squamulosus, squamulis adnatis varie 

 lobulatis (latit. circiter 0*5 millim.), ssepe in granula sorediosa dis- 

 solutis, hypothallus niger ; apothecia testaceo-rufa (latit. circiter 

 1 millim.), margine thallino crenato cincta ; sporse longit. 015- 

 0*017 millim., crassit. 0010-0011 millim. Iodo gelatina hyme- 

 nialis cserulescens, deinde vinose violaceo-rubens (thecse pnesertim 

 tinctse). 



This is an easily distinguished species, with the squamules 

 or less scattered or subimbricate on a black continuous hypo-
