Pound and Clements: north American hyphomycetes. 667 



21. SPICARIA Harz. Hyphom. 50. 1871. 

 Sporophores erect, hyaline, branches perfectly verticillate; 



conidia hyaline, ovoid or oblong. 



1 species is reported from this country. 



22. HAPLOGRAPHIUM B. & Br. Ann. Mag. Nat. Hist. no. 



818. 1859. 



Sporophores erect, fuscous, the apex inflated, denticulate; 

 conidia fuscous, simple, globose to oblong, catenulate, the 

 catenulae arising from the terminal denticulations of the spor- 

 ophore. 



The species in which the sporophores are branched at the 

 apex are referred to SchizocepJialum. We retain here only 

 those in which the branches are reduced to mere denticula- 

 tions. But one species is reported from the United States, 

 which may be included in the genus as here limited, — H, apicu- 

 latum Pk. 



Tribe Stacliybotryteae. 



Vegetative hyphae present, creeping; sporophores erect, 

 branched or simple, bearing verticillate sterigmata (basidia) at 

 the apex, fuscous or hyaline; conidia single, solitary, acrogen- 

 ous or acropleurogenous. 



23. STACHYBOTRYS Corda. Ic. Fung. 1:21. 1837. 

 Sporophores erect, elongate, branched, rarely simple, crown- 

 ed at the apex with heterogeneous, verticillate sterigmata 

 which are connate at the base, fuscous; conidia acrogenous, 

 globose or ovoid, fuscous, simple, rarely 1- septate. 



5 species are reported from this country. Several of the 

 species are stages of Ohaetomium. 



24. STERIGMATOBOTRYS Oudem. Contr. Myc. Pays Bas. 



11:48. 



Sporophores erect, typically simple, crowned at the apex 

 with free, heterogeneous sterigmata, fuscous; conidia acropleu- 

 rogenous, globose or ovoid, fuscous, simple. 



1 species is reported from the United States: 



Stekicmatohotrys elonoata (Pk.) 



Staehybotryt tlongata Pk. Rep. N. Y. Mus. 43:— (29). PL 3. f. 10-13. 1890. 



25. CYLINDROCLADIUM Morg. Bot Gaz. 17:191. 1892. 

 Sporophores erect, di- or trichotomously branched, the tips 



crowned with 2 — 3 verticillate sterigmata, hyaline; conidia 

 acrogenous elongate-cylindrical, 1-septate, hyaline.
