262 MR. F. CURREY ON SPHÆRIZÆ. 
ascigeras, quas equidem legi stylosporas, alias equidem ascigeras, ille vidit stylosporas. 
Multiplex nuclei varietas est causa cur noluerim genera admittere nisi aliis differentiis 
et habitu proprio confirmata. Quam plurimas vidi Sphærias sporis primo simplieibus, 
dein uniseptatis, demum triseptatis; limites inter sporas septatas Curr. et pseudo- 
septatas et endochromate multipartito difficiles. Equidem sporarum colorem accuratius 
censeo indicare affinitatem. 
“ Ut Discosie, Chatomia, &c., sic etiam Phoma, genus eximie naturale, inter ascigeros 
citanda. Recentiores Phomatis nomen ad Zythias, a me jam pridem dictas, perperam 
retulerunt, licet character nullo modo in has quadret. Ejusmodi nominum transposi- 
tiones confusionem necesse pariunt, quare caute evitandæ et corrigendæ.” 
With reference to the above remarks upon the structure of spores, I may observe that 
I make no distinction between what I have called pseudoseptate spores and spores with 
multipartite endochrome. I apply the term * pseudoseptate” to those spores in which 
the separate portions of the endochrome are in such close contact as to give rise to the 
appearance of septa where none really exist. It is quite likely that in all such spores 
true septa are eventually formed. The question as to the value of the colour of the 
spores is too extensive to be discussed at the end of this paper. In some genera (e. g. 
Cordyceps, Xylaria, Hypozylon) the colour is very constant; in others, again (e. g. Dia- 
trype, Valsa), there is much variety. Even closely allied species (e. g. Valsa quaternata, 
V. turgida) sometimes differ considerably in the colour of their sporidia.
