theii" margins. Pocletia aVjoufc 2 mm. high, '60 mm. thick, 

 olivaceous, thallino-corticate and sub-granuloso asperulate, 

 or often towards the apex decorticate and somewhat rose- 

 coloured, monocephalous. Apothecia about equally broad 

 with the podetia ; the whole of the apothecium at first 

 rosello fuscescent and very widely truncato obconical and 

 plane, but soon fuscous and convex. Spores not fully 

 evolved. Prof. J. Mueller in Ratisbon Flora. 



Genus 3. — Thysanothecium, Berk, and Mont. 



Thallus partly horizontal, granulose or squamose, and 

 partly podetiiform, often expanding at the apex, variousl}'' 

 divided. Apothecia thin, ])ale or rufous, darker or lighter, 

 terminating the terete podetium or covering the upper 

 surface of the frond-like podetium. Spores small, ellipsoid, 

 simple. 



1. T. hyaliuum, Tajdor. 



Thallus pale yellow or pale lurid, lobato granulose or 

 squamose ; podetia various in size (1 to 12 mm. high, -5 to 

 2 mm. thick), sulcato rugose, sometimes squamulose below ; 

 apex dilated on one side (J to 10 mm. broad). Apothecia 

 pallid or carneo-rufescent, or fusco rufus, forming a thin 

 stratum on the upper surface of the apex. Spores 8 in the 

 thecEe, ellipsoid, simple, -006 to "008 x -0035 (Nyl.) 



Hab. on earth or decayed and generally burnt wood, 

 common ; Kew, Box Hill, Youyangs, Cobden, Mordialloc, 

 Cheltenham, Oakleigh, Ringwood, Lilydale, M.atfia. 



Form squamulosum, Wilson. — Thallus yellow, more or 

 less sordid or lurid, squamulose, squamules thick, either 

 depressed and lobate, or somewhat ascending podetiiform, 

 swollen upwards and briefly ramose. Apothecia cephaloid, 

 sessile on the squamules and podetia, minute, crowded, not 

 fully evolved. 



Hab. on poor soil, Trentham (coll. by Mi-s. Martin), Kew, 

 Sandringham. Possibly a ncM^ species. 



Form intortum, Wilson.— Thallus yellow, squamulose, 

 podetia compressed and dilated, lobulate, apices crispate and 

 intorted. Apothecia as in the typical form. Spores not full}^ 

 evolved.
