from Australia, sent to Kew thirty years ago and two specimens are 
at New York. Rehm so determined, (as Xylaria ) for Rick, Xylaria 
discoidea of Brazil that has no suggestion, of it whatever, but Rehm 
was only guessing and made a bad guess. Prom the resemblance of the 
photographs? I have supposed Poronia Doumetii to be the same, but 
while they look alike, same size and shape, the habits are entirely 
different. Indeed there is no other Poronia known that "grows on 
a stump" as this is said to grow. A close examination of the co¬ 
type at New York discloses a thin, carbonous crust under the thick, 
white, external coat, hence perhaps it is technically a Xylaria. 
Still 1 think it is better classed as Poronia. 
PORONIA USTORUM (Pig; 1737"),- Exceptional in its habitat, the 
burnt stem of grasses, there can be no trouble in recognizing the 
species which is a trite Poronia with carbonous. perithecia imbedded 
in a white stroma. The spores are 6 X 12 and the photograph shows 
the remainder. It has been recorded in New Caledonia, in South 
America, but no specimens have reached me. Co-types, are found, at 
New York. Type is at Paris, from which our photograph is made. 
Synonyms or unknown to me 
Poronia cupularis, Europe, Fries. Said by Nitschke not to 
be a Pyrenomycete^ but he does not state what it is. 
Poronia scutellata, Europe, based on Micheli, T. 54, Pig. 3, 
is supposed to represent Poronia punctata, but if so it is very poor 
and Micheli stated it grew on the ground. 
Poronia pocula. is the name under which the unique little 
Polyporus Pocula was first proposed., 
Poronia fornicata,. Judging only from Moeller’s figure and 
publication, and a specimen I so referred from Rev. Torrend, Brazil, 
this is the same plant we consider now as Kxetzschmaria Kunziana. 
It is a question whether Kretzschmaria or Poronia.. The contiguous 
perithecia are aberrant in either genus and it has a thick crust not 
found on Poronias, and not carbonous- as in Kretzschmaria. 1 am in¬ 
clined to think it is better classed as Poronia in which case it 
would become Poronia Kurziana (Currey ) McGinty, 
Poronia leporina. The material I have seen, is scanty and 
I am not sure about it, but if Ellis' or Massee's enlarged drawings 
are correct it is a Poronia. I do not believe either is correct. 
It is a very minute species on rabbit dung. 1 opine it is not a 
Poronia at all and thet both drawings were made to fit the idea. It 
semmed to me to have a black, carbonous crust instead of a fleshy 
disc as shown, and I believe it to be Xylaria Tulasnei of Europe, 
which was illustrated by Tulasne as Xylaria peduncu'lata var. pusilla 
and which also grew on rabbit dung. I have seen Tulasne's plant in 
Europe, and as near as I could judge Ellis' plant is the same. 
"Poronia" leporina is known from one collection, Demetrio, Missouri, 
thirty years ago. Perhaps if our American collectors would more 
closely observe rabbit dung they would find it more often. 
The following species have not been noted by me: Poronia
