Crandmia glauca Oke. is not a Grandinia but belongs to the Thelephoraceous 
genus Kpithele (see No. 411). 
ODONTIA Fr. 
(Gr., odouft, a tootli.) 
‘ ‘ Receptacle resupinate, thin, membranaceous ; waxy, crustaceous or mealy. 
Spines conical, ciliate or penicillate at the apex. Spores hyaline. Cystidia 
j)reseiit. ’ ’ — E. M. Wakefield. 
398. Odontia arguta (Fr.) Quel. (L., argutus, sharp). — "Effused, thin, mem- 
branaceous, dry, margin indeterminate, tomentose, whitish. Hymenium cream to 
deep ochraceo'us, with granuliform or subulate spines usually more or less 
penicillate at the apex. Basidia clavate, 20-30 x 5 ft, with 4 sterigmata, accom- 
panied by small cystidia or cystidioles of varying form, sometimes rounded above 
and excreting a globule of ' resinous matter, sometimes subulate and strono-ly 
encrusted at the apex. Spores ovate, often one-guttulate, 5-5.5 (-0) x 4 g. 
Ilyphae hyaline, with clamp-connections, 2-.1 g in diameter. On baik and deatl 
wood.” — Wakefield. New South Wales^-Pilliga Scrub. Tasmania — Brown's

399. Odontia Archeri (Berk.) Wakef. (Syn., Corticmm Archeri Berk.; Kneiffla 
Wrightii B. et C. ; K. chromoplumhea B. et Br. ; Corticmm chrysooreas B. et C. ; 
Odontia Wrightii (B. et C.) Burt.) (After William Archer, 1820-1874, a noted 
Tasmanian botanical collector). — ‘‘Broadly effused, firm, fairly thick, but not 
waxy, closely adnate, at first thin, even or more or less ])apillate, later with 
distinct spines, becoming much thicker and when dry often cracke(l into small 
areolae. Hymenium variable in coloui’, yellow oclire when young and actively 
gj'owing, but becoming cinnamon-buff or olive-buff then avellaneous or wood brown 
with age. Margin indeterminate, at first buff-yellow or Empire yellow, later 
concolorous with the hymenium. Subiculum similarly bright yellow at first, 
but in old specimens the tissue exposed in the cracks often appears white, 
probablv on account of the abundant excretion of crystals from the tissues. 
The structure in section is very characteristic, but can onlv be observed well in 
young specimens. Numerous cystidia arc present, both embedded in the tissues 
and projecting slightly from tlie hvmenium. Tliese are small, sliortlv fusiform, 
thin-walied and liyaline at first, 18-20 x (i-8 g. Later the embedded cystidia 
become strongly encrusted with a deep yellow, aiiparently resinous excretion, 
whiiPh is soluble in a solution of potassium liydrate with the production of a 
vinaccous tint. It is insoluble in lactic acid and the structure is best observed 
in sections mounted in this medium. The encrusted cystidia eventually occupy' 
consi<lerable space in the subhymenial tissues, and appear to be vesicular bodies, 
as described by Burt for Coriicimm chrysocreas. Basidia 15-20 x 4.5 g, with 4 
sterigmata, 3 g long. Spores liyaline, elliptical, one side depressed, sometimes 
2-guttulate 4.5-5 (-0) x 2-2.5 g.' Basal tissue at first somewhat compact, later 
the hvphae appear to be loosely interwoven, hyaline, thin-walled, .3-4 (-5) g in 
diamrter. The tissue in older specimens contains much mineral matter in the 
form of crystals, often forming masses in the central tissue of the spines. On 
bark. ’’—Wakefield. South Australia— Mount Lofty. New South Wales— Mosman.
