FUNGI. 29 



On yellowed dead twigs of Cornus, at Durango, 20 March. 

 Conspicuous from the yellowed cuticle containing the 

 thickly scattered perithecia which come away with it. 



MELANCONIACE^;. 



CORYNEUM UMBONATUM, Nees. Syst. 34. On dead oak 

 twigs, at Hermosa, 29 March ; n. 21. 



DEMATIACE^:. 



CAMPTOUM CUSPIDATUM, Cke. & Hark. Grev. xii. 33. On 

 dead stems of Scirpus, Durango, 22 March; n. 17. 



CLADOSPORIUM TYPHARUM, Desm. Sacc. Syll. iv. 366. On 

 dead leaves of Typha, at Hermosa, 4 April; n. 18. 



MACROSPORIUM PUCCINIOIDES, Ell. & And. Bot. Gaz. (1891), 

 47. On dead twigs of Chrysothamnus, at Durango, 21 

 March; n. 34. 



This striking fungus can hardly belong in the genus 

 Macrosporium. Its compact growth suggests the Tubercu- 

 lariacise rather than the Dematiacese. The only recognized 

 genus of the former family with muriform spores is Spegaz- 

 zinia, but our fungus differs widely from that genus in habit 

 and in that the corridia are not borne on sterigmata but on 

 the ends of the sporophores. 



TUBERCULARIACE.E. 



TRIMMATOSTROMA AMERICANA, Thiim. Myc. Univ. n. 793. 

 On dead willow twigs, Durango, 20 March; n. 72.

 scattered, erumpent, prominently convex, constricted below, 

 large, l-2mm., bright salmon red, texture fibrous rather 

 than waxy, in cross section the fertile portion, colored alike
