CLASSIFICATION 449 



the spines. Was at one time considered to be a species of Hydniim, 

 but differing in microscopical structure. 



T. gelatinosum. — More or less fan-shaped, fixed by a narrowed 

 portion, 1-3 in. long, upper surface polished, brownish with an 

 opalescent tinge ; hymenium spiny, pale gre}^ 



Our only gelatinous fungus with a spiny hymenium. 



On pine stumps, branches, etc. 



Dacryomyces 



Gelatinous, forming small, wart-like convolute masses of a 

 yellow or orange-colour on dead ^\'ood. 



D. deliquescens. — Roundish or irregular, convoluted more or 

 less, yellow, 1-4 lines across. 



Fruiting best during M'inter, forming yellow con\-ex masses on 

 pine wood, boards, rails, etc., often growing in lines out of cracks 

 in the wood. 



D. stillatus (PI. XXX, fig. 8). — Similar in size to D. deliquescens, 

 but firmer, and of a deep orange-colour. 



On pine and other decaying wood. 



D. chrysocomiis. — Circular in outline and depressed in the centre 

 or saucer-shaped, not wrinkled, golden yellow, about i line across. 



On rotten pine wood. 



D. macrosporus. — Gelatinous, forming rosy tubercles or warts, 

 forming patches up to \ in. long. 



On dry branches. 



D. succineus. — Subgelatinous, gregarious, smooth, amber-colour, 

 paler externally when moist, rather thick, collapsing when dry. 



This species is said to be the conidial condition of an ascomycetous 

 fungus, Peziza eleclrica. 



On dead pine leaves. 



D. sebaceus. — Gelatinous but firm, cup-shaped, whitish. Con- 

 spicuous in wet weather, 2-4 lines broad. 



On branches. 



D. torta.- — Gelatinous, rounded, depressed, tuberculate, and 

 with the surface wavy and lobed, yellow or orange. 



Differs from D. deliquescens by the smaller spores, which are 

 3-septate and measure 12 X 4-5 /^. 



On decorticated oak branches. 



Calocera 

 Gelatinous but firm, growing erect, simple or much branched. 

 The largest and most frequent species resembles a deep orange- 

 coloured Clavaria, differing in its distinctly gelatinous, tough 

 substance. The smaller species are dingy orange, and grow gre- 

 gariously on wood.
