Remarks 
Two forms of this species were described by 
Cairns and Zibrowius (1997), one having a flat 
base, the other a concave base (see New Records). 
Off Western Australia the flat-based form was 
found at a shallower depth (304-450 m) than the 
concave-based form (452-720 m). 
Distribution 
Western Australia: continental slope of 
northwestern coast from south of Scott Reef to Port 
Hedland; 304-720 m; 8.4°-10.7°C; always reported 
on a soft/mud substrate. Elsewhere: Indo-West 
Pacific (widespread from southwestern Indian 
Ocean to Kermadec Ridge, including Japan); 245- 
2000 m (Cairns and Zibrowius 1997).

Lady: stn RW96-29, 1, NTM C8088; stn RW96-31, 
1, NTM C8091. 
Remarks 
Fungiacyathus fragilis is similar to the previous 
species but can be distinguished by lacking 
paliform lobes (P2) and having much lower septal 
lobes. It is compared to all other species in the 
subgenus by Cairns (in press. Table 3). The 
specimen from Lady stn RW96-31 is 52 mm in 
calicular diameter, the largest known corallum of 
this species. 
Distribution 
Western Australia: continental slope of 
northwestern coast between Browse and Cartier 
Islands; 400-420 m. Elsewhere: cold temperate 
New Zealand; cold temperate North Atlantic; 
Hawaiian Islands; 285-2200 m (Cairns 1995).
