club, rarely two from a stem. Generally obtuse, rarely acute. It 
is frequent in the States, rare in Lurope. In the tropics it is 
generally smaller than in the temperate regions and more flattened 
and irregular* Then it is called Xylaria rhopaloides but is really 
the same species. 
Isaria flabelliformis is supposed to be the conidial form of 
Xylaria corniformis * V/e have long contended that it was an error 
but of late years specimens that seem to confirm it have reached me 
from three correspondents. 
Xylaria corniformis has a general resemblance to Xylaria 
polymorpha and Pries admits that he confused them at first. It may 
be recognized by its pannose base, smaller spores and by its habits. 
It usually grows singly (sometimes gregariously but very rarely 
caespitose) on logs and even small branches. 
In American mycology Peck recorded Xylaria corniformis as 
Xylaria castorea. My statement that he somewhere so called Xylaria 
fusca was an error due to relying on a faulty memory instead of look¬ 
ing up my notes. Schweinitz recorded the species as Xylaria bulbosa, 
a rare species in Purope that I do not know excepting from books, but 
which differs in habits growing in the ground in fallen pine needles. 
It has never been found with us. Rehm determined Xylaria corniformis 
for Dearness as "Xylaria leprosioides", I suppose a "new species" 
although he determined Xylaria biceps for Rick under the same name. 
For Atkinson, Rehm determined the same species or rather the slender 
form of it (X. rhopaloides) as "Xylaria aphrodisiaca vel approxima". 
Rehm's ideas of Xylaria species was very vague. 
Vfe present in Fig. 1582 the extreme forms that Xylaria corni¬ 
formis takes, but it is misleading for as a rule Xylaria corniformis 
is a rather uniform species. Rarely it takes misshapen forms as 
shown, Fig. 1583 from Rev. Rick. 
XYLARIA VIOLACBO-PANNOSA (Fig.1584).- Yhile it has a dis¬ 
tinct violaceus color, surely it should be referred as Theiszen 
refers it to Xylaria corniformis. Spores 4X8. 
XYLARIA RHOPALOIDDS (Fig. 1585).- In the tropics Xylaria 
corniformis takes slender forms and usually is irregular in shape 
and more flattened and the pannose base is not so strongly developed. 
These are called Xylaria rhopaloides. It was so distributed (as 
Sphaeria) in the old Kunze exsiccata, and the name was used by 
Montagne but it was not described. It is the common form in the 
tropics and rarely specimens are collected in the States which are 
better referred to it than to the usual form. 
ADDITIONAL DALDINIAS 
Since our article on this genus was published we have noted 
two species in the New York Botanical Garden that we had not seen 
before. 
DALDINIA CLAVATA. YThen our article was printed we had no 
specimen suitable for illustration, but v/e found one at New York 
among the unnamed Xylarias. Tre present a photograph (Fig.1586) and 
a section. It is the only cylindrical Daldinia known.
