CLASSIFICATION 451 



Apyrenium 



Subglobose, gelatinous, hollow, the liymenium covering the 

 entire outer surface. 



Distinguished amongst the Tremellinaccce by the entire structure 

 being inflated and persistently hollow. This is considered to be a 

 spurious genus, the species being suspected of being conidial con- 

 ditions of ascigerous fungi belonging to the genus Hypocrea. This 

 opinion awaits corroboration, or otherwise. 



A. lignatile. — Sessile, rounded but variously deformed, smooth, 

 externally and internally pale yellowish, collapsing when dry, and 

 becoming wrinkled. Up to \ in. across. 



Sometimes showing a reddish tinge when dry. Supposed to be 

 a stage of Hypocrea rufa. 



On pine wood, decaying fungi, etc. 



A. armeniacum. — Subgelatinous, lobed, peach-colour, 1-2 lines 

 across. 



Smaller than .1. lignatilis, more irregularly lobed, and brighter 

 in colour. Said to be a conidial form of Hypocrea gelatinosa. 



On oak chips, decaying fungi, etc. 



Gyrocephalus 



Erect, narrowing downwards into a short stem, more or less 

 spoon-shaped, irregular, between cartilaginous and gelatinous, 

 Hymenium on one surface only of the flattened portion. 



G. riifiis. — Erect, flattened and more or less concave, spoon bowl- 

 shaped or very obhquely funnel-shaped, somewhat gelatinous, but 

 very variable in shape, tapering downwards into a short stem, 2-3 

 in. high and nearly as wide, orange to red or scarlet above ; stem 

 orange. 



On rotten trunks and on fragments of wood, and on the ground 

 under conifers. Very rare. 



GUEPINIA 



Substance between cartilaginous and gelatinous, unequally or 

 obliquely saucer-shaped, substipitate. 



G. peziza. — Cup-shaped or saucer-shaped, attached obliquely to 

 the tapering stem ; hymenium yellow or orange, about J in. 

 across. 



Cup oblique, often irregular, hoary, and often tinged with pink 

 when dry. 



On dead branches, trunks, etc. 



G. obliqua. — Cap slightly concave, attached obhquely to the 

 stem, which is very short and tapering downwards ; liymenium 

 bright orange, tinged with pink when dry, 1-3 lines across. 



On wood. Gregarious.
