118 AUSTRALIAN FUNGI, 



slightly or not at all constricted at septa, straight or bent, 40-70 x 7- 

 Sfx. Conidia obclavate, olivaceous to pale fuliginous, transverse 

 septa up to 19-20, deeply constricted, with long pale-coloured 

 septate beak and body of sporidium muriformly divided, 100-160 

 X 16-25/x. 



Sydney, N.S.W.; on Carnation; August, 1903 (R. T. Baker). 



The exceedingly long spore of this species is very characteristic, 

 deeply constricted at the septa, and may either be comparatively 

 slender or bulging considerably. Sepfoyna dianthi also occurred 

 on the leaves. This species is after the type of A. solani (E. <fe M.), 

 Jones ik Grout, in which the spore may be more than twice as long, 

 but the transverse septa are fewer and less constricted, and the 

 longitudinal septa are few or lacking. 



Amphich^ta, n.g. 



Acervuli beneath the epidermis, often erumpent, disc- or 

 cushion-shaped, black. Sporules elongated, with two or more 

 transverse septa, at least partially coloured, and with one seta at 

 each end; basidia hyaline, filiform. 



The genus Pestalozzia was originally divided into the three 

 subgenera, Eu-Pestalozzia with sporules partly coloured and two 

 or more apical setae; Monochcetia with only one apical seta, and 

 Pestalozzina with the sporules entirely hyaline. The two latter 

 are now raised to the rank of genera, and JIo7iochcetia, Sacc, 

 corresponds to this new genus, onl}^ there is no basal seta to the 

 spore. In Cryj^tostictis, Fckl., the spores are similar to those of 

 Amphichceta, but they are enclosed in a perithecium. 



62. Amphich^ta daviesi^, n.sp. 



Pustules black, erumpent, subgregarious, sometimes confluent, 

 on both surfaces of leaves and on stems. Sporules fusoid, 4- 

 septate, hardly constricted at septum, 3 median cells coloured, 

 2 terminal hyaline, crested with one hair up to 20/a long, with 

 another usually shorter hair springing obliquely from basal cell 

 near to junction with stalk, 20-26 x 7-8/x; basidia hyaline, filiform.
