166 FUNGUS-FLORA. 



patches. Sometimes pale flingy yellow. The margin is 

 either sterile or covered with spines. Colour sometimes 

 pale yellowish or very pale Luif. 



CALDESIELLA. Sacc. (fig. 3, p. 149.) 



Spines minute, conical or ampulliform, springing from a 

 membranaceous, persistent villose subiculum ; spores globose, 

 mnriculate, copious. 



Galdesiella, Saccardo, Mich. i. p. 7 ; Sacc, Syll. vi. p. 477. 



Distinguished from Hydnum by the mui icate spores being- 

 very copious, and by the loose texture of the subiculum. 



Resembles the teeth of a Hydnum in the subiculum of 

 Ilypochnus or Coniophora. I have liatl no opportunity of 

 examining the species included in the present genus in a 

 fresh state, hence cannot say definitely whether the fungus 

 is a true Basidiomycete or not, that is, whether the spores 

 are borne on true basidia, or singly at the tips of unthickened 

 branches, as in the family Ilyphomycetes. The profusion of 

 spores points to the latter ; this, however, must be settled by 

 some one examining fresh material. 



Galdesiella ferruginosa. Sacc. (fig. 3, p. 149.) 



Subiculum efiused, often fur several inches, tawny-ferru- 

 ginous, tomentose ; spines crowded, conico-subulate, acute, 

 colotired like the subiculum, straight or oblique and com- 

 pressed ; spores globose, 8-9 /j. diameter, distinctly muriculate, 

 dingy olive. 



Cnldestclla ferruginosa, Sacc, Mich. ii. p. 303. 



Hydnum fcrrugtnosum. Fries, Syst. Myc i., ji. 41(3; Stev., 

 Fung., p. 242. 



On decaying wood, especially under the bark ; rarely on 

 the ground. Separable from the matrix. 



The whole plant consists of den scl}'- woven down, forming 

 an efi'usetl indeterminate mass, tlie hymenium comjjosed of 

 erect or oblicpie spines, which are villous and often abortive, 

 so as easily to be taken for some sjiecies of the sub-order 

 Hyphomyri'tcs. The colour varies from ferruginous to 

 brownish. (Berk.)
