Dublin Microscopical Club. 143 
Budding in Polyzoa.—Prof. Haddon showed budding state of 
Polyzoa, illustrating late union of the lophophore with the stomach, 
and the origin of part of a bud from the endocyst and part from the 
funiculus. 
Augite Crystal_—Prof. V. Ball exhibited a transverse section of 
an augite crystal from the Vesuvian lava of 1794. Under polarized 
light this is a very beautiful object, and exhibits striae which mark 
the position of a plane of twinning. A photograph of it, magnified 
about 25 diameters, taken by Prof. G. F. Fitzgerald, represents this 
character, some included cells, and the structure of the matrix with 
admirable definition. The photograph was taken by electric light. 
Foraminifera from the Vienna Basin.—Mr. Eleock showed a fine 
series of mounted (fossil) Foraminifera from the Vienna basin, re- 
marking that many were identical with those from oceanic collections 
made during the expedition of H.M.S. ‘ Challenger,’ in fact in no way 
distinguishable. 
Alliospora sapugaye, Pim, further phases—Mr. Pim drew atten- 
tion to the fungus shown by him last year, and provisionally named 
Alliospora sapugaye. The description in the Club Minutes, though 
correct in so far as it went, proved on further investigation imperfect, 
inasmuch as the spore-bearing hyphe do not originate, as was thought, 
directly from the globose columella, but from a layer of somewhat 
wedge-shaped closely packed cells forming an outer coat, whose 
thickness is twice or thrice the diameter of the columella, The 
sporiferous hyphe, moreover, are frequently branched articulately 
at the tip, where spores are formed, as in the genus Penicillium. 
May 24, 1883. 
Pileolaria tercbinthi exhibited-—Mr. Pim showed Pileolaria tere- 
binthi, a native of Genoa, from specimens in the herbarium at Trinity 
College, Dublin. This curious rust is technically a Uromyces, but 
the lenticular spores with extremely long slender pedicels are abun- 
dantly distinct from any ordinary form of that genus. 
Section of Stem of Lycopodium.—Prof. M‘Nab exhibited a trans- 
verse section of the stem of a species of Lycopodium, probably Lyco- 
podium ilictfolium, from a plant growing in the stove at Glasnevin, 
The central fibro-vascular cylinder presented a peculiar complicated 
appearance on account of its construction, the xylem and phloem 
being partly concentric, partly radial, according to the types of 
DeBary. The centre was concentric, whilst the periphery of the 
axile cylinder consisted of alternating radial bundles of xylem and 
phloem. 
A problematic Organism.—Dr. E. P. Wright showed a mounted 
specimen of a peculiar and problematic organism which he had 
found in some quantity, quite incrusting the root-like portions
