separated by vesicular bodies which become greatly inflated an<l thin-walled 
and are finally up to 20 to 00 x 15 spores hyaline, even or slig'htly rough, 
subglobose, 4.5 to 7 /r or 0 x 4.5 to 5 On decaying wood of coniferous species 
usually. ’ ’ — Burt. 
Burt states that it may be recognised by its occurrence on coniferous wood, 
whitish or ivory- yellow colour, white fimbriate margin, subglobose spores about 
(i in diameter and the piesence in sections of very lai'ge vesicular bodies which 
may be so inflated ami have walls so tenuous that they appear as vesicular spaces 
between the crowded hyphae. 
South Australia — A specimen from Mount Lofty, June 21, 1924, was identified 
by Professor E. A. Burt. The fi'uctifications are patchy, .3 to (i x 1 cm. in extent, 
near Light Buff (xv. ) or almost rusty-stained, paling towards the periphery, thin, 
on rough bark encrusting some debris of leaves, etc., the margin whitish, broad, 
radiating and fibrillose. Europe. North America. Alaska. 
414. Corticium portentosum Berk, et Curtis. (Syn., C. diminuens Berk, et 
Curtis). (L., portentoKUS, p)ortentous, strange). — “Fructifications long and widely 
effused (4 to 12 cm. x 2 to 4 cm.), thiok, coriaceous-soft, small pieces separable 
when moistened, white, becoming light buff' to warm buff' in the herbarium, even, 
only rarely cracked, tlie margin often whitish, pubescent-villose; in section 150 
to 1,000 /r thick, coloured like the liymenium, becoming zonate or stratose when 
thick, composed of very densely inteiavoven, tough hyphae, about 1 to 2 /r in 
diameter, not incrusted, not nodose-septate, j)rotruding in the hymenial surface 
as curved paraphyses ; mo)'e or less numeious aggregations of mineral matter 
may be immersed in the substance; no gloeocystidia; basidia few; spores hyaline, 
even, spherical, 4.5 to 7 p in diameter, few present usually. In bark and wood 
of logs of f rondose species. ’ ’ — Burt. 
Burt says that it may be recognised by its large, whitish, coriaceous fructifi- 
cations on frondose logs, which become zonate within in thick specimens, and 
have globose spores (i m in diameter, and the slender branches of the interwoven 
hyphae exceeding the basidia and forming the hymenial surface. 
South Australia and New South Wales — Specimens have been identified by 
Professor E. A. Burt from Kangaroo Island, May, 1925, and from Wingham, 
N.S.’VV. Fructifications very extensive, up to 30 x 10 cm. or more, covering the 
irregularities of dead wood, tliick. Light Buff (xv.), only occasionally cracking; 
liyphae very fine, 1 to 1.5 fi, irregular, intricately interwoven; spores subspherical,

CORTICIUM. SUBGENUS GLOEOCYSTIDIUM Karst. 
(Gr., gloios, sticky; Icystis, a bladder.) 
“Differs from Cortioiiim in possessing gloeocystidia, generally immersed in 
the tissue, which lesemble cystidia, but their walls are never thickened or 
incrusted with crystalline deposits. ' ’ — Rea. 
No Australian species recorded. 
ASTEROSTROMA Masse. 
(Gr., aster, a star; stroma, anything spread out for lying or sitting upon.) 
“Receptacle effused or reflexed, at first thread-like. Hvmenium with star- 
shaped brown setae. Spores globose or elongated. ’ ’ — Killermann. 
415. Asterostroma sp. — Forming thin incrusting Honey-Yellow' (xxx.) patches, 
up to lin. X 'tin. (2.5 x 1.2 cm.), tending to run together, edge rather indefinite, 
surface subvillose. Substance with star-shaped and prong-like bodies, the prongs 
acicular and acute, 9 p long, base 2.p y, yellowish, in a felted mass with the 
hj^fliae. Spores not seen. South Australia — Near Bakers Gully, Clarendon. 
June. 
BONIA Pat. 
(After Bon, a collector in East Asia.) 
“Receptacle leathery or papery, reflexed or deeply concave. liymenium rough 
with short, close-set many-celled setae almost Hydnum-like. ’ ’ — Killermann. 
No Australian species recorded.
