79. C. chrysocreas Berk. & Curtis, Grevillea 1: 178. 1873; 

 Sacc. Syll. Fung. 6: 618. 1888. 



Corticium crocicreas Massee, Linn. Soc. Bot. Jour. 27: 151. 

 1890; v. Hohnel & Litschauer, K. Akad. Wiss. Wien Sitzungsber. 

 116: 776. 1907. Not C. crocicreas Berk. & Curtis. 



Type: type distribution in Ravenel, Fungi Car. 5 : 27, under the 

 name Corticium crocicreas. 



Fructifications broadly effused, rather thick, closely adnate, not 

 at all separable, apricot-yellow and olive-ocher to dark olive-buff, 

 even or becoming somewhat papillate, cracked in drying, the 

 margin thinning out, indeterminate; in section 120-300 \l thick, 

 olive-ocher throughout, composed of erect, densely interwoven 

 and conglutinate colored hyphae about 2 \l in diameter, of very 

 numerous vesicular organs 15-21 X 6-9 n; coloring matter of the 

 sections becomes vinaceous upon treatment with potassium 

 hydrate solution and the sections are finally bleached; spores 

 white in a spore collection, even, 43^-5 X 23^ ;x. 



Fructifications 3-8 cm. long, 1-3 cm. wide. 



On wood and bark of decaying logs of frondose species. South 

 Carolina to Louisiana and Missouri, in Mexico, in West Indies, 

 and in Japan. July to April. Occasional. 



C. chrysocreas has olive-ocher fructifications of the same color 

 throughout which make it one of the most conspicuous species of 

 the region bordering on the Gulf of Mexico. Several other Gulf 

 species have a northern station in Missouri or Illinois. The 

 vesicular structure in section is an important distinctive char- 

 acter for separation of this species from Odontia Wrightii, which 

 has the same color and geographical range but angular granules 

 in the hymenium.
