Cove in South Australia. As an anomaly, a specimen of one Geaster showed 

 the presence of two mouths. 



Polystictus cinnabarinus, Jacq. On dead wood. A widely distributed species 

 probably occurring throughout Australia. 



Polyporus (Hexagona) decipiens, Berk. On dead wood of Casuarina 

 stricta, Ait., near the summit of the tallest peak. Spores pallid brown, 17'5 to 

 19X8 to 95 /x. Associated with these typical specimens, but growing from the 

 upper surfaces of the logs, were sessile, or nearly completely sessile, nummular 

 round or oval polypores, the largest 18X15 mm., the others 11 mm. or less in 

 size. The substance was thin, the upper surface marked with shallow rather 

 hexagonal honeycomb-like pits, varying in diameter in different specimens from 

 about 1 to 3 mm. The size of the orifices was considerably larger than in typical 

 H. decipiens. The colour also was a dark cinnamon-brown, in contrast to the 

 greyish-brown of the normal hymenial surface. The spores, however, were of 

 the pallid brown colour of those of H. decipiens and obliquely elliptical to 

 rather mummy-shaped. Their size was somewhat larger than in the case of 

 the normal plants, being 22'5X9'5 /x. I have no doubt that these were merely 

 abnormal examples of H. decipiens, growing in an unusual situation, the upper 

 surface -of a fallen log. 



Corticiuni sp. A milk-white Corticinm, found on a fallen log, seems close 

 to C lacteum, Fr. Waxy-membranaceous. effused, but the edge not fibrillose, 

 flesh slightly isabelline, spores not seen. 



Polysaccuni pisocarpiiim, Fr., var. tuberosum. Globose, 2 5 cm. in diameter, 

 surface now pallid, spores rough, 8 to 9 /x. 



Lycoperdon polymorphum, Vitt. Sterile base definite, of small cells. Moder- 

 ately developed root. Spores yellow-brown, smooth or slightly rough, 5 fx; 

 capillitium brown, branching, ends blunt, 2'5 to 5 yu, in diameter. 



Catastoma sp. A single battered specimen was obtained. Exoperidium 

 ill-defined, mouth not now recognizable, gleba "Front's Brown" (Ridgway, 

 pi. XV.). Spores yellow-brown, smooth, pedicles not seen, spherical to slightly 

 irregular or slightly oval, 4 to 6 |U,; capillitium brown, 2 to 3'5 ju, in diameter, 

 usually: in short lengths with blunt ends and with occasional knob-like 

 thickenings. 



Geaster minimus, Schw. Under Casuarina, etc., near the summit of the 

 tallest peak ; the other Geasters were found in the same situation. Spores dark 

 brown, slightly rough, 6 /x. 



Geaster fornicatus, Batt. A number of typical specimens were found 

 amongst' the leaf -mould near Casuarinas, etc. The mould was permeated through 

 and through with the white mycelium which bound the particles together so that 

 it could be lifted in considerable masses. Spores dark brown, very slightly 

 rough, 6 fx. 



Geaster saccatus, Fr. Some badly damaged old specimens appear to belong 

 to this species. 



Geaster sp. Exoperidium not incurved, divided beyond the middle into 

 about 9 to 11 narrow acute lobes. Endoperidium dark coloured, now smooth; 

 mouth sulcate, scarcely protruding. Gleba dark purplish-brown. Spores very 

 dark brown, rough, 65 ju,.
