NuMMULARiA pusiLLA, Sacc. \ Hedwigia, XXYIII., p. 127, 

 Stromata very small for the genus, strictly applanate, blackish, 

 elliptical oblong or sinuous, 2 mm. -diameter, or 4 to 5 by 2 mm., 

 scarcely -5 mm. -thick, soon becoming superficial by the seceding 

 periderm ; everywhere fertile, blackish, somewhat shining, with a 

 rectangular margin, the periphery vertical ; disk smooth ; ostioles 

 punctiform, somewhat crowded, with the small not prominent 

 margin visible only under a lense ; perithecia parallelly crowded 

 together, roundly oblong, often unequal, \ mm. high and \ mm. 

 thick ; asci cylindrical (soon nearly absorbed) ; sporidia 8, broadly 

 fusiform, rather straight, somewhat pointed at each end, 18 to 22 

 by 6 ■z* in diameter, variously guttate, fuliginous. On dead 

 branches of Bursaria spinosa, at Callington. It seems to be- 

 allied to JV. cydisea, Mont., Syll. Pyr., I., p. 370, to iV. microsticta, 

 Mont., Syll. Pyr., I., p. 371, to iV. scutata,, B. t C, Syll. Addit., 

 p. 57, and to Hyjoox. stigmoides ; but well distinguished by the 

 form and small size of the non-pruinose stromata, by the largish 

 non-caudate sporidia, kc 



Septoria Bromi, Sacc, Syll. Sphaeropt, p. 562. Perithecia, 

 150 u broad, widely perforate ; sporules tortuous, continuous 

 40 to 50 by 1 to 1-5 u. Differs from >S'. KoelericE by the peri- 

 thecia three times larger, the spots obsolete. On the sheaths 

 and leaves of grasses at Murray Bridge. 



Pleurotus ch^tophyllus, Sacc, Hedwigia, XXVIII., p. 125. 

 Dimidiate, obovate-spathulate, thin, very shortly stipitate, with 

 acute at length rather straight margin, densely shortly white- 

 tomentose ; stipe rather thick, rugulose ; lamellae narrow, very 

 crowded, generally entire, colour from white to tan, reaching the 

 stipe, everywhere roughened (under a lense) with small fusiform 

 (cystid) subochraceous setulse, 30 to 40 by 12 to 15 u; spores 

 elliptic-reniform, hyaline, 5 by 3 w, smooth. On branches in South 

 Australia. Pileus with stipe, 15 to 20 mm. long, 12 to 14 mm. 

 wide, stipe 3 mm. thick. The cuticle under the hair blackens in 

 drying. Allied to P. limjndioides, Karst., Sacc, Syll. Y., p. 365,, 

 but the lamellae are setulose, not conjoined, everywhere narrow, 

 spores reniform, &c.
