PAPULOSPOKA— GLIOULA.DIUM. 293 



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

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

 oblong spores. (Grove.) 



PAPULOSPOEA. 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. 



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



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

 some authors to be a single many-celled conidium. 



Papulospora sepedonioides. 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, 10-15 /a long. 



Papulospora sepedonioides, Preuss, Fl. Hoj'ersw., n. 40 ; 

 Sacc, SyU., 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. 



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

 Bot., vol. xxiii. p. 10. 



Differs from Penicillium in the spores being produced 

 singlj', not in chains, but remaining united in the mucous 

 substance simultaneously excreted. (Grove.) 



Gliodadium penicillioides. Corda. 

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

 thickened above, white ; branches opposite, branchlets
