Phytcia excelsior Strn. (p. 40). „Thallus orbicular, to 1 — 2 in. wide 

 Teddish or ciunabar-coloured, beneath concolorous or paler, with long linear- 

 laciniate (K purpurasant) prostrate segments, flat or rather convex width about 

 0,6 mm ; dichotomous or towards the apex many times divided and ascendent, 

 on all sJdes lengthily and very densely fibrillose ; apothecia concolorous, 

 rather prominent, marginate, the margins often paler and somewhat spinulose 

 below; spores 8, colourless , oblong or rarely ellipsoid, polari-bilocolar, the 

 tubulns very shortly or not at all joined, 13—17 X 6— 8 i"i paraphyses 

 distinct , with citrine apices , sprinkled with granules. Hymenium 

 with J coerulesant. — This is evidently quite distinct from any of 

 many forms of Physcia chrysophthalma. On bark, New-Guinea. u 



P annaria pannosa var. accolens Strn. (p. 40). „Similiar to 

 P. pannosa Sw. ; but the thallus more lead-coloured, and the mature spores 

 brownish. Spores 8, simple, allipsoid, epispore duplex, 14 — 18 X 7 — 10 p ; para- 

 physes scarcely separable, with brownish clavate apices ; hypothecium colourless. 

 On bark, New-Guinea." 



Lecidea subcoerulea Strn. (p. 40). „Thallus thin, continous, pallide 

 or pale greeuish; apothecia brown, 0,4 — 0,8 mm, girdled with a rather 

 prominent, whitish, entire margin ; sporae solitary, colourless, oblong, divided 

 into tricke-like cellules, 60—90 X 12—18 p ; paraphyses distinct, filiform, 

 slender, few, branched towards the apex, which is faintly coloured and a 

 little club-shaped; hypothecium a sordid blue, finally fulvescent, subtended by 

 a bluish continuous Stratum. The hypothecium has a bluish (not purplish) 

 tint in younger apothecia, which changes to a dirty greenish colour, and this 

 ultimately becomes fulvescent. The continuous blue Stratum beneath the 

 hypothecium is also peculiar. Hymenium, especially the thecae, coerulescent 

 with J, the paraphyses scarcely tinted, while the spores (under the same 

 reagent) are flavescent. On bark, New-Guinea." 



Verf. macht noch darauf aufmerksam, dass seine Pyxine 

 obscurior, in Proceed. Roy. Soc. of Victoria. 1881 beschrieben, 

 möglicherweise eine Buellia sei.

Collema hypolasium Strn. .(p. 484). „Similar to C. reflectans Nyl„ 

 but obscure, and the epithallus not cellulose, and beneath the thallus densely 

 and closely tomentose or velvety. Spores 8, in saccate thecae, ellipsoid, simple, 

 halionate, 16—20 X 7,5—10 /u. On bark." 



Collema Gwytheri Strn. (p. 484). „Thallus obscurely olivaceous or 

 nigro-viresceut , appressed, membranaceous, lobate, with ascending lobules, 

 margins somewhat crisp and crenate ; beneath aimost concolorous and nude. 

 Apothecia brownish-red, flat, with a thin entire thalline ring. Spores 8, colour- 

 less, aimost cylindrical or arcuate, 7—10 usually 8 nucleate. Epispore scarcely 

 visible, 25—35 X about 3 p. Hym. with J conrulescent. Gonimia encatenate 

 small. On pranches of trees."

 imbricate lacinia, margins crenulate and sinuose-lobate, bluish-black, shortly and 

 sparingly covered with black fibrils. Medulla with (K — C — ). Apothecia 

 brown, 2 — 4 mm wide, flat, margins often crenulate. Spores 8, colourless, simple,
