up ^ he s P ecimen if it exists and elucidate this wonder¬ 
ful but apparently illusive discovery. 
PHYLLOCARBOF YASTJDAI FROM A. YASUDA, JAPAN (Fig. 2008).- 
./lien the plants of the tropics and foreign countries are well collect¬ 
ed, many unexpectedly unfamiliar ones will be found. We supposed we 
had reached the limit when we received Pyrenopolyporus from Africa, 
a dimidiate, pileate Pyrenomycete; and Porodiscus from Brazil, a 
poroid Pyrenomycete; and here we have a foliaceous Pyrenomycete. 
The loose, carbonous tissue is very much the same as that of the 
common Ustulina„ vulgaris but the plant while not pliable is foliace- 
oug in form and attached by a small attachment. No doubt it grew 
on top of a log. Color is black and on the lower side it bears 
globose, hyaline, conidial spores about 3 mic. in diameter. There 
is no evidence of perithecia but no doubt they will be found at a 
later stage as most Pyrenorrycetes have an earlier, conidial state. 
sent as a Basidiomycete, but it is a 
safe 
proposition 
The plant was 
that no fungi of carbonous tissue are Basidiomycetes. I hope Prof. 
Yasuda will continue to observe the plant and finds its asciferous 
state. Based on Yasuda, collection 633, Mt. Kirishima, Japan. 
ALEURODISCUS TSUGAE FROM A. YASUDA, JAPAN (Fig. 3009).- As 
named by Prof. Yasuda. Thin, resupinate, effused, with the distinct 
margin. Color white with slightly cinereous cast. • Basidia large, 
with four long sterigmata and typical of the genus. Spores globose 
or subglobose, 16-20 mic., hyaline, smooth. Paraphyses filiform, 
hyaline, but seen with difficulty in a section. This grew on the 
bark of Thuja, It belongs in Section 4 of our recent resume and is 
close to Aleurodiscus macrosporus but differs in its globose spores. 
A section shows a thin layer with hardly any subiculum. The large 
basidia and erect crowded hyphae have numerous interposed, irregular 
crystals. The paraphyses are difficult to make out and are not sure 
as described. 
ALEURODISCUS STEREOIDES FROM A. YASUDA, JAPAN (Fig. 2010).- 
As named by Professor Yasuda. Pileate from a reduced base. About 
1 cm. in diameter, thick, rigid, conchoid. Surface smooth, fuligin¬ 
ous grey with raised zones. Hymenium greyish. Basidia cylindrical, 
10 mic. thick, hyaline, with slender sterigmata. Paraphyses 
(Fig. 2011) long, cylindrical, 10 mic. thick, smooth, rarely with a 
few granular incrustations, mostly abruptly contracted near the 
slender, acute apices. Hyphae ligneous, 10-12 mic. thick, pale 
colored. Spores compressed, globose, 16 X 20, smooth, with very pale 
colored granular contents and a minute apiculus. 
In old times this would have been a Stereum. It does not enter 
into either of the sections we proposed and we have to make a new 
one, ”2 l/2 Pileate from a reduced base, not effused," Prof. Yasuda 
has given it a good name for it is a good Stereum. He records the 
spores as finely punctate, but they appear to me smooth, the effect 
due to thin, granular contents.
