PORONIA. PILEIPORMIS (Pig; 1721).- Plant with a sclerotoid 
base and long stem was figured from the Philippines by Berkeley in 
1842. Our ligure is from the type at Kew. Currey gives the sporea 
as 7-8 mic. long and our figure tells the rest, Cooke includes it 
as an Australian species but I do not know on what basis. I have a 
suspicion that it is the same plant as the next. 
PORONIA MACRORKIZA (Pig.1722 ).— In 1907 I received a most 
curious plant Irom A. D. Machado, Perak. It proceeded from a sclero - 
tium, had a long, black, branching stem and a white, soft, floceose 
head. I sent it to Patouillard and he advised me that he thought 
it was an immature Poronia. Last summer in the New York Botanical 
Garden I found a. collection of a most curious Poronia which was 
mature and remarkable in the soft, white, cottony texture of the 
stroma in which the perithecia were imbedded. It came from Peru and 
was collected on "cow dung" by 0. P. Cook. While it has no sclero— 
tiun. (probably broken off) I am satisfied it is the same as that I 
received from Perak. The spores are 6 X 26. The remarkably soft, 
cottony tissue of the head and the figure we give will enable it to 
be identified when found again, 
Poronia pileiformis from the photograph appears to be the 
same, but I did not note that the type had the soft, cottony stroma, 
and Currey's spore record does not apply. I do not know Poronia. 
macrorhiza excepting from description which does not mention the 
soft stroma., but coming from the same locality, having the same 
sclerotium: and spores, there is but little doubt, and Spegazzini 
probably did not know the usual texture of Poronias. 
PORONIA HEMISPHAERICA (Fig-, 1723 ).- This is the only species 
we have not seen, and we present the figure that was made of it 
(natural size). It is very small, has a hemispherical head, a 
sclerotoid base and grows on cow manure in Brazil. It seems to be 
based on a single immature specimen and possibly it is an incipient 
specimen of Poronia macrorhiza. It is the same size and shape of 
Xylaria discoidea. and at one time we discussed the possibility of 
its being that plant, but no doubt we were mistaken. "New species" 
should not be based on such, scanty, immature material. 
PORONIA EHRENBERGII (Fig. 1724).- This is a large species 
with a long stem that is completely buried in the sand, only the 
head appearing on the surface. It was collected in Arabia, the s 
spores said to be 16-21 X 30-40, and our figure tells the remainder. 
PORONIA DOUMETII (Fig. 1725).- This is the same in appearance 
and habits as the preceding and came from Tunis. The heads are hemi¬ 
spherical and the spores 9 X 15 are the character on which it was 
separated from Poronia Ehrenbergii. Both have the spores enveloped 
in a thin, mucilaginous covering, indicating the relation to manure 
loving-species. 
PORONIA AGARICIFORMIS (Fig. 1726).- Heads hemispherical, 
white, punctate with the black ostioies. Stipes an inch or two long 
black, smooth. Spores 7 X 14 mic. 
A hemispherical Poronia was so unexpected that Cooke referred 
it to Xvlar?a , evidently on its shape. But one collection is known
