Meliola cladotricha, Lev. — Branch-haired Meliola. 

 (Plate XXVIII., fig.s. 21-23.) 



Hypophyllous. Spots roughly orbicular, black with brownish 

 tinge, velvety, 4-6 mm. diameter, often confluent. Mycelium of 

 dark brown, thick-walled, septate filaments, branching antler-like, 

 ultimate branches tapering and more transparent, up to 9 /x broad. 

 Perithec.ia in groups at the centre of the spots, black, globose, 

 fully }r mm. in diameter, and covered with numerous, rigid, usually 

 curved or flexuous, simple, septate, brown appendages. Asci 

 oblong or elongated- elliptical, 4-8 spored, sessile, 66-112 x 26-37 fi. 

 Spo7'idia at first colourless, then yellowish-green, finall}- brown, 

 elongated-ellipsoid, triseptate, 43-47 x 17 /x. 



On leaves of Eugenia sj:). August. Richmond River, N.S.W. 

 (Baker, 8). 



The colourless sporidia are stained canary-yellow with potassium- 

 iodide iodine, and both coloured and colourless may be together 

 in the same ascus. The mycelium radiates at the circumference 

 of the spot in the form of distinct, seal-brown, branching fila- 

 ments, and the denser darker centre bears the globose perithecia 

 in groups.

Clay-coloured Botrytis. 



(Plates XXVII , figs. 14-17; xxviii., figs. 18-20.) 



Gregarious, firm, orbicular, tubercular, sometimes confluent ; 

 clayey-brown, rather large but variable in size; from 2 mm. to 

 1 cm. in diameter. Conidiophores densely compacted, collectively 

 dark brown, individually almost hyaline, straight, septate, 

 repeatedly laterally branched, and towards apex usually branched 

 in a tri-radiate manner, contents finely granular, about 4^ fj. 

 broad. Conidia produced terminally, pale yellowish to colourless, 

 continuous, elongated-oval to ovate, 9^-11x4-5^ fj.. Young 

 tubercles are of firm consistency and black in section, but magni- 

 fied the sections show light and dark coloured layers; old tubercles
