NOTE ON CORTICIUM LEUCOTHRIX, B. & C. 
A. P. MORGAN. 
I have recently gathered specimens of this curious fungus. 
It was first described by Berkeley in the Notices of N. A. Fungi; 
it is No. 284. The hymenium is truly “beset with delicate white 
bristles” as stated by Berkeley. These the hymenium had parted 
with when Massee redescribed the same specimen in the Journal 
of the Linnean Society, Vol. XXV, 133. 
The species was referred to the “subgenus” Coniophora, by 
reason of “Hymenium pulverulent; spores large, profuse, col¬ 
ored,” Grevillea, VIII, 89. It stands here Corticium (Conio¬ 
phora) leucothrix B. & C. Massee writes it Coniophora leuco- 
thrix Cooke, in the Journal of the Linnean Society. 
The peculiarity of the plant is the association of the white 
cystidia with the brown spores; the former pertain to the genus 
Peniophora, the latter are characteristic of the genus Coniophora. 
The cystidia of Corticium leucothrix are similar to those gener¬ 
ally in the species of Peniophora; they are terete, tapering 
slightly to the apex, roughened with irregular warts, projecting 
50-90 mic. beyond the surface of the hymenium, 12-15 mic. in 
thickness. The spores are subelliptic, inequilateral, yellow-brown, 
pellucid, 11-14x6-7 mic. 
The cystidia in the genus Peniophora, after maturity, soon 
disappear, especially when the plants continue to be exposed to 
the weather; then the specimens are usually referred to Cor¬ 
ticium. It can easily be shown that this has been done in more 
than one instance. 
THE ACCENTUATION OF MYCOLOGICAL COMPOUND 
NAMES. 
IVY ICELLERMAN. 
It seems that the perplexing question of correct formation 
and derivation is not the only matter in nomenclature which dis¬ 
turbs the botanist. The accentuation of names gives trouble now 
and again, in spite of the apparently simple rule for all an¬ 
glicized Latin and Greek scientific words, that the Latin rule is 
to be followed, namely: accent the second syllable from the end 
if it be long; if it is short, accent the preceding one. But since 
these words are chiefly Greek compounds, some explanation of 
the laws underlying their accent before they suffer transliteration 
may replace apparent dogmatism with reasonableness in the mind
