PAPULOSPORA GLIOCIADIUM. 293 



observed. My specimens belong rather to Penzig's form, 

 but scarcely differ from Corda' s figure, except in. the more 

 oblong spores. (Grove.) 



PAPULOSPORA. Preuss. (figs. 1, 2, p. 358.) 



Sterile hyphae creeping, effused, septate ; fertile branches 

 or conidiophores ascending, septate, bearing at the tip a 

 head of conidia that does not readily separate into its 

 component conidia. Conidia globose or elliptical, colourless 

 or coloured. 



Papulospora, Preuss, Fl. Hoyers., n. 40; Sacc., Syll., iv. 

 p. 58. 



The head of conidia, as described above, is considered by 

 some authors to be a single many-celled conidium. 



Papulospora sepedonioid.es. Preuss. (figs. 1, 2, 

 p. 358.) 



Sterile hyphae effused, branched, septate, interwoven, 

 brownish-rust colour; conidiophores colourless, septate, 

 bearing at the tip a cluster of agglutinated conidia forming 

 a red head ; conidia oblong, 1015 p. long. 



Papulospora sepedonioides, Preuss, Fl. Hoyersw., n. 40; 

 Sacc., Syll., n. 282. 



On decaying cabbage stalks, rotten apples, &c. 



GLIOCLADIUM. Corda. 



Stem erect, septate, penicillate above, branches and 

 branchlets septate, crowned by a common gelatinous head. 

 Conidia acrogenous, irregularly heaped together, simple, 

 with a gelatinous coat. 



Gliocladium, Corda, Icon. Fung., iv. p. 31 ; Grove, Journ. 

 Bot., vol. xxiii. p. 10. 



Differs from Penicillium in the spores being produced 

 singly, not in chains, but remaining united in the mucous 

 substance simultaneously excreted. (Grove.) 



Gliocladium penicillioides. Corda. 

 Tufts minute, punctiform, white; stems erect, flexuous, 

 thickened above, white ; branches opposite, branchlets
