like), with an impressed ostiole round which the tissue is 
darker. Spores oblong-ellipsoid, usually obtuse at both ends, 
often biguttulate, involved in mucus, perfectly hyaline, 4-4-5

There can be no hesitation in deciding that Spegazzini’s 
species is the same as that of Berkeley: the supposed difference 
in the size of the spores disappears on examination, and the 
delicate byssoid subiculum mentioned by Berkeley is not, now 
at least, apparent in his specimens. 
But Cooke’s British species (placed under the same name) is 
quite different. On examining his specimens (Cooke, Fung. 
Brit. Exs. no. 413!) on millboard, London, 1875, one finds, in- 
addition to a number of loose spores, a mixture of two forms. 
One is no doubt a Hyphomycetous stage of the other and, 
although not now specifically determinable, is obviously an 
Aspergillus. The other is a Pyrenomycete, belonging to the 
Perisporieae, and seems to be absolutely identical with Cepha- 
lotheca Kriegeri, Rehm (Ascom. Exs. fascic. 44, no. 1850, on 
white paper: see Annal. Mycol. 1909, vii. 405, and Sacc. Syll. 
xxii. 30). The only possibility of doubt lay in the fact that 
no asci could now be found, but the tendency of the spores to 
cling together in clusters (such as is known to all mycologists in 
Eurotium herbariorum and other species of that group) at once 
suggested that they had originally been contained in asci. The 
latter are known to be very diffluent in many of the Perisporieae, 
and their absence has often led to mistakes in description, as in 
Cooke’s case here and also in Saccardo’s Mycogala parietinum 
which is in most cases nothing but Anizxia (ascis praetervisis). 
Though no specimens of Rehm’s were at hand for comparison, 
the agreement of the British fungus with the account given in 
Annales Mycologici (l.c.), in every detail except those concerning 
the asci, leaves no loophole for hesitation.
