Calocera palmata Schiwn. 



Branched, tremellose-tough, orange-yellow, compressed, di- 

 lated upward, divided; the branchlets subterete, divaricate, 

 obtuse. 



On decayed fallen branches of Rhus globra, woods, Glen 

 Ellyn. August. On decaying wood of Quercus, River Forest. 

 June. Plants 12 to 16 mm. high, simple, slender and subulate, or 

 divaricately branched near the base, the branches occasionally 

 divided near the apex; spores somewhat hyaline, curved, 9 to 10 

 x 6ft. 

 Calocera cornea Batsch. 



Cespitose, rooting, even, viscid, yellow-orange; clubs short, 

 subulate, connate at the base. 



On decaying pine logs, Millers. Growing in lines out of the 

 cracks in the wood, the bases of the plants fused together at the 

 base, so that a strip several cm. in length can be stripped from 

 a crevice in the wood. The individual plants are 5 to 6 mm. high. 



GUEPINIA. 



Cartilaginous-gelatinous, versiform, the two surfaces diverse 

 in structure; substipitate ; hymenium unilateral; spores curved. 



Guepinia spathularia Schw. 



Nearly erect, stipitate, spathulate, the stipe and upper side 

 cinereous-pubescent. 



Hymenium plicate, orange-yellow; spores curved, apiculate, 

 three-septate, 10 to 12 /x. 



Growing in linear series in cracks of a decaying log of Tilia. 

 Woods, Lombard. September. 



EXIDIA. 



Blackish, cup-shaped, truncate or effused, smooth or slightly 

 plicate, papillate; basidiospores 2-4 celled on germination, bear- 

 ing curved sporidiola. 



Exidia glandulosa Bull. 



Effused, nearly plane, thick, undulate, becoming black, spicu- 

 lose with conic papillae, the underside cinereous and somewhat 

 tomentose. 



Spores oblong, curved, 12 to 14 x 5 /*. 



Crevices of bark of decaying logs of Quercus. Riverside. 

 Plants pellucid when growing on the underside of the logs where 

 not exposed to sunlight; spores elliptic-reniform, 10 to 12 x 6 /x. 



TREMELLA. 



Yellowish or whitish with brain-like convolutions, homoge- 

 neous ; basidiospores, sporidiola and conidia when present globose 

 or ovoid. 



Plant white . . . T. fuciformis 



Plant cinnamon-flesh-color T. foliacea
