AUSTRALIAN FUNGI. 
company with Aster omella). Asci globose, with a small basal 
apiculus. Sporidia elliptical, uniseptate, constricted at the 
septum, hyaline, 11-20 X 8 p (possibly acquiring colour when 
mature). 
On living leaves of Trema aspera. Zandina, Queensland. 
(Bailey, 902.) 
Asteromella epitrema, Cooke. 
Spots on the upper surface, black, somewhat orbicular or con- 
fluent, bearing a mycelium of brown jointed threads. Perithecia 
minute, subglobose, membranaceous, seated on the mycelium. 
Sporules numerous, somewhat fusiform, or narrowly elliptical, 
continuous, guttulate, hyaline, 10-12 x 3 p. 
On living leaves of Trema aspera. Zandina, Queensland. 
(Bailey, 902.) 
In company with Dimerosporium parvulum . 
Piggotia substellata, Cooke. 
On the under surface, forming small somewhat orbicular stellate 
black patches (1-2 m.m. diam.), composed of the confluent, 
flattened perithecia, which are sometimes distinct, seated on rather 
larger tawny spots. Sporules cylindrical, straight, obtuse at the 
ends (8x1 p), hyaline, on longer simple basidia. 
On leaves of Eucalyptus. Victoria. (Mrs. Martin, 744.) 
Leptothyrium aristatum, Cooke. 
Perithecia scattered, superficial, scutate, orbicular, submem- 
branaceous, radiately cellular, dark brown (y 1 ^ m.m.). Sporules 
cylindrical, strongly curved, obtuse at the ends, with an oblique 
hyaline bristle at one end, equal in length to the sporule, hyaline, 
14-15 X 2-3 p. 
On dead leaves of Eucalyptus. Victoria. (Mrs. Martin, 752.) 
Stagonospora orbicularis, Cooke. 
Forming small orbicular pallid spots (5 m.m. diam.) on either 
surface, circumscribed by a brown line. Perithecia few (3 to 5) in 
the centre of the spots, covered by the cuticle, which is at length 
cracked, globose depressed, black. Sporules fusiform, acute at 
the ends, curved, 3-5 septate, constricted at the septa, hyaline, 
60-70 x 8 p. 
On dead leaves of Eucalyptus. Victoria. (Mrs. Martin, 740, 
768.) 
Stilbospora foliorum, Cooke. 
Epiphyllous. Pustules on orbicular paler spots, splitting the 
cuticle, with three or four orifices, through which the sporules 
escape. Stroma flattened, conidia broadly elliptical, a little 
narrowed towards each extremity, three septate, not constricted, 
olive brown, becoming nearly opaque (22 x 8-9 p). 
On dead leaves of Eucalyptus . Victoria. (Mrs. Martin, 
132.)
