228 CURREY— MYCOLOGICAL NOTES. 
while to record these supplementary observations. The hy- 
menium of Patellaria clavispora is stated im the ‘ Annals’ to 
be of a brown colour. My specimens appear quite black to 
the naked eye, assuming, however, a brown tinge when the 
hymenium is wetted. A thin vertical section shows that 
this brown colour is entirely owing to the small brown stylo- 
spores or conidia which are attached to the tips of the para- 
physes, and which bear some resemblance to the spores ofa 
Cladosporium. ‘These bodies are represented in Pl. XJ, fig. 
8 a—e, all magnified 325 diameters, except 4, which is mag- 
nified 450 diameters. They are, as I have mentioned, of a 
brown colour, and consist of two, sometimes three, cells; the 
cells sometimes exhibiting a nucleus, as in J, d, e, sometimes 
not, as in a, c. The paraphyses not unfrequently produce 
two stylospores at the apex, as is seen in fig. 8 a, and are 
occasionally furcate at a distance from the apex. The other 
kind of fruit consists of asci containing sporidia. The 
asci are linear, and the sporidia, two of which are drawn in 
fig. 8 f, g, are somewhat clavate, exhibiting, when young, a 
row of nuclei, as shown at f; but when more advanced they 
become three- or four-septate, and have a granular endo- 
chrome. The length of these sporidia I found to be 0:0014 
to 0:0016 inch, a measurement exceeding that of Messrs. 
Berkeley and Broome, who state the length of the fruit in 
their plants to be 0°0010 inch. Mere difference of size in 
the sporidia is, however, not sufficient for the separation of 
species which agree in other particulars, and I therefore do 
not doubt that the Patellaria here figured must be considered 
the same species as that described in the ‘ Annals of Nat. 
History.’ 
Patellaria atrata, ¥r.—I find growing very commonly upon 
worked wood a species of Patellaria which I believe to be P. 
atrata, of Fries, and which, if I mistake not, exhibits two 
different sorts of fructification. The ordinary or perfect 
fruit of the species in question is drawn in fig. 9, and consists 
of asci containing eight rather’ long, fusiform, slightly- 
curved, multi-septate sporidia. The specimens in which I 
find the other sort of fruit do not differ materially from the 
ascigerous specimens, except in being of a very much smaller 
size. ‘The hymenium of these smaller plants produces no 
asci, but is formed of a mass of cylindrical or clavate, septate 
spores, such as are shown in fig. 10 a, b,c. If we imagine 
the asci above mentioned to bear only one sporidium each, 
the result would be the production of a number of bodies not 
very dissimilar from the septate spores. I do not mean to
