9. Hydnum udum (Fr. Ep. p. 517). 
Haz. On dead wood, Archer, 
Gen, XIX, IRPEX, Fr. 
Hymenium inferum, primitus dentatum; aculei varii, seriatim 1. reticulatim dispositi basique plicis 
lamellosis (in sessilibus) porosisve (in resupinatis) concatenati. 
Distinguished from Hydnum by the connected teeth. From Polypori they differ in not being essentially 
porous. (Name from irper, a harrow.) 
l. Irpex Archeri (Berk.); albus, resupinatus, margine tomentoso arachnoideo, dentibus reticulato- 
connexis brevibus palmatis. (Tas. CLXXXIII. Fig. 1.) 
Has. On dead wood, Archer, 
Effused, resupinate, white; margin thin, tomentose, arachnoid, barren, Teeth connected at the base, short, 
palmate.—This curious species is allied to Radulum palmatum, Berk., and with that and one or two more will pro- 
bably form a genus distinguished from Irpex by its palmate teeth. In R. palmatum (Ann. Nat. Hist. ix. p. 445) the 
teeth are one or two lines long ; in this, which has essentially the same structure, they do not exceed half a line. The 
genus, if it be thought worthy of being distinguished, may be called Cladodontia.—Piate CLXXXIII. Fig. 1; a, 
plant, nat. size; 6, hymenium, magnified, 
Gen. XX. GRANDINIA, Fr. 
Hymenium amphigenum, ceraceum, primitus granulosum, granulis subspheericis obtusis excavatisque. 
Distinguished from allied genera by the granular nature of the aculei. The species approach sometimes very 
close to Kneifia. (Name from grando, hail; in allusion to the granular hymenium.) 
1. Grandinia granulosa (Fr. Ep. p. 527). 
Has. On decorticated wood, Archer, 
2. Grandinia australis (Berk.); resupinata, effusa, immarginata, pallida, rimosa, intus nivea, hyme- 
nio granulato, granulis uni-bipapillatis. 
Has. On dead wood, Archer. 
Entirely effused and resupinate, without any evident margin, pale, white within, cracked. Hymenium rough 
with unequal granules, each of which has one or more distinct papille.—This appears to be quite distinct from any 
of the European species, and to approach near to Kueiffia, from which it differs only in the papilla not being pro- 
longed into bristles. 
Gen. XXI. ODONTIA, Fr. 
Hymenium inferum, fibroso-contextum, protrudens verrucas apice cristato-multifidas inter se discretas. 
A genus consisting of a few species only, separated from Hydnum by its wart-like, crested aculei. (Name from 
oôovs, a tooth.) 
1. Odontia secernibilis (Berk.) ; resupinata, membranacea, secernibilis, alba, aculeis brevissimis 
compressis subdivisis. 
Has. On dead wood, J. D. H., Archer. 
Resupinate, separating entirely from the matrix, white, membranaceous, rather irregular. Teeth very minute, 
short, tomentose, compressed, slightly divided or toothed.—This has the habit of H, ochraceum, but the teeth of 
Odontia.
