A thicker form, more hoof-shaped, with a dark brown crust on^ the older 
portion and a. rounded pallid grevish-lirown edge, with the tube orifices inoie 
irregular and a little larger (to d in 1 mm.) occurs with us (Mount Lofty, 
National Park, Kuitpo — May, .hme, October). 
Dr C Gr Lloyd distinguishes P. J^crttpo.^ius Er. from P. gilvu.^i by its being 
excessively rough with little tubercles and granules, but doubts whether it can 
be maintiiined even as a form. Some of our s})ecimons could be considered as 
P. scnipo.nis. 
P. lic-hnoides Montague is, according to Lloyd, a very thin form of P. gilvus, 
almost like Polyntictus. AVe have specimens he has identified from Narrabri and 
Milson Island in New South Wales but have not met with it in South Australia. 
Polyporus gilvus is a common species and, with its related forms, can readily 
be recognised bv the usually bracket sha])e, the rougli granular to strigose brown 
upper surface, the tough gilvous (yellow ochre to buckthorn brown) context, the 
rather small brown orifices and 'microscopically by the colourless spores and 
brown setae. 
.108. Polyporus subcontigua Clel. et Rodw. (S^th, here from the resemblance 
fo Poria contigua Pers.). — Sometimes forming small ungulate Foines-like brackets, 
occasionally when the attachment is narrowed almost stalked, 5 'mm. in size, with 
a greyish-iirown rather radiately rough c.onvex upper surface an<l a convex or 
concave pallid under-surface on which the irregular pores appear (these colours 
may be due to weathering). These small brackets may be alone present or the 
plant may be almost entirely resupinate, with here and there small brackets or 
narrow shelves with the above features. The resupinate jiortion may extend over 
several centimetres (e.g., (i x 2 cm.), is very thin (1 to 3 mm.), and is near- 
Brussels Brown (ill.) to Prout ’s Brown (xv.) or Ta-^vny Olive (xxix.) and 
darker, sometimes with a more gilvous subtomentose edge near Bucktliorn Brown 
(XV.). The pores are irregular, 3 to 4 in 1 mm., often oblique, the dissepiments 
thin and rather lacerated in the I'csupinate part, thicker and more rounded in the 
pileate, the mouths glancing, appearing pallid in certain lights, brown in others. 
The substance is tough, dark brown in the pileate portion, with no very evident 
subiculum, the pores being probably stratose and Fom-es-like. Spores ( hyaline, 
5 to 7 X 3.5 g; hyphae yellow-brown, thick-walled, 2 to 4 /r; setae dark brown, 
subulate to acuminate with a broad base, 2(i to 55 x 4 to 9 /ti at the base. South 
Australia — On fallen trunk, Onkaparinga River, near Clarendon; Myponga; 
Williamstown ; on fence post, fTare; Flinders Range, near Quorn. AA'estern Aus- 
tralia? .Tune, August. 
The species can be recognise<l by the size of the pore-mouths (3 to 4 in 1 mm.), 
the presence of brown setae, and the tendency to form nai'i'ow shelves or small 
ungulate brackets. The small size of the latter, when occurring without a 
resupinate extension, renders them difficult to detect, the upjier surface resembling 
the dead woo(l of the substiatum, but the pallid poi'e-bearing surface, seen in 
the brackets but not noticeable in the resupinate extension and probably partly 
due to fading, forms a contrast when the log is turned, which draws attention 
to the fungus. 
329. Polyporus Ludovicianus Patouillard (Ltidovicianus, adjectival of a 
proper name). — Dr. C. G. Lloyd considers tliis as a thin form of P. outicularis 
Bull, which is placed under his Fourth General Division with spores and context 
coloured, and in Section 100 with brown context and setae. In this section 
P. cutioularis is placed in subsection A with the surface tomentose or hispid,.
