Stipe slender, tapering at each end, hollow; pileus conic- 
campanulate, with its surface granulate or minutely wrinkled 
after disappearance of the gleba; veil membranaceous, usually 
less than one-half of the length of the pileus, loosely attached to 
the stipe in the angle between the stipe and pileus; stipe closed 
at the apex by a thin membrane or finally perforate; volya 
pinkish. 
Plant 4 to 7™ long (10 to 17™); stipe 3/™ thick (15 to 20"); 
pileus 1%™ high (2.5 to 3.5°™). Growing in woods and fields 
about rotting wood. New England, various collectors ; New York, 
Peck; South Carolina, Ravenel; Ohio, Morgan, 
This species has been placed in the genus Dictyophora on 
account of its having a persistent membrane hanging about the 
stipe from the angle between the pileus and the stipe. This 
membrane is composed of the same tissue, the intermediate 
tissue A of my figures, which gives rise to the veil in D. dupl- 
cata. Differentiation of this tissue does not advance in D. _ 
Ravenelii to the final stage of making this membrane pseudo: 
parenchyma, or is this final stage reached in the case of hyphe 
composing the pileus in /. zmpudicus and in D. duplicata, yet ets 
one would hesitate on that ground to use the term pileus 0 
connection with those species. It seems best to apply the term 
veil to this membrane in D. Ravenelii, which looks like a veth 
has the position of a veil, is composed of the tissue forming th 
veil in other species, and is likely to be regarded as a veil with 
out question by every botanist meeting this fungus for the fist 
time and attempting its determination. aS 
I have as yet had no opportunity of studying this struct” 
except in an advanced egg-stage, very kindly placed at my dis 
posal by Professor Thaxter, but that a differentiation tow" 
the stage of pseudoparenchymatous hyphz exists in the se 
seemed to be indicated by some laterally inflated hyph® we 
were observed in the section, as well as by the persistence 
the structure ina membrane which becomes torn away from : 
under surface of the pileus on the one side and from the wall 
the stipe on the other, during elongation.
