458 Rev. M. J. Berkeley and Mr. C. E. Broome on British Fungi. 
represented by Corda and confirmed by ourselves. Endotrichum 
of Corda again has a close external resemblance, but a glance at 
the figure and description shows clearly that they cannot belong 
to the same genus. Labrella punctum, Corda, may also be com- 
pared with it. The extremely close external resemblance of ob- 
jects belonging to as many very different genera would make a 
nice subject for amplification to those who adopt the notions pre- 
valent with some of the transformation of species.

449. Coryneum compactum, nu. s. Minutum primitus tectum 
sero denudatum ; sporis late fusiformibus obtusiusculis, nucleis 
concatenatis. On dead twigs of elm, Wraxall, Som., March 1845. 
It occurs also in Upper Carolina on Betula rubra. . 
Forming minute scattered pustules at first quite covered by 
the cuticle, at length exposed. Stroma convex; spores pedun- 
culate, widely fusiform, slightly obtuse, 4—5-septate, nuclei large, 
connected with one another. 
This species bears nearly the same relation to Stz/bospora py- 
riformis that the next does to S. angustata. The nuclei are con- 
nected with one another after the fashion of the endochromes of 
Sirosiphon ocellatus, Kiitz., Saccothecium Corni, Mont., Helmin- 
thosporium Hoffmanni, Berk. and Curt., and some others. The 
shape of the spores is very much that of the same organs in 
Hymenogaster griseus, Tul. 
450. C. disciforme, Kze. Myc. Heft 1. p. 76. On dead twigs 
of birch, woods near King’s Cliffe. 
b. ellipticum, Berk. & Br. Magnum transversum ; stromate 
elliptico crasso pulvinato, sporis pedunculatis multiseptatis fusi- 
formibus ; endochromatibus ut plurimum biguttatis. On trunks 
of birch-trees, King’s Cliffe. . 
Bursting transversely through the bark, large, elliptic, pulvi- 
nate ; stroma thick, white, black towards the edges, consisting 
of closely-packed elongated cells ; spores fusiform, multiseptate ; 
articulations slightly constricted ; endochromes granular, con- 
taining generally two transversely arranged globules. 
We were at first inclined to consider this a new species, but 
specimens exactly agreeing with Corda’s figure have since oe- 
curred on smaller twigs, which exhibit occasionally two globules 
in the endochromes, and we now regard it merely as a very highly 
developed form. 
451. C. microstictum, n.s. Tectum ; stromate obsoleto ; sporis 
minutis breviter lanceolatis 2- 3-septatis. Sporocadus rosacola, 
Rab. no. 1166. On dead twigs of rose, vine, Kerria japonica, 
&e. Sent by Mr. Stephens, Mrs. Hussey, &c.
