The Fungi of Texas. By M. C. Cooke, A.L.S. 



[Eead April 4, 1878.] 

 „ (Abstract.) 



The communication of which the following is an abstract con- 

 tained an enumeration of a small collection of Fungi made by Mr. 

 H. W. Ravenal in a trip to Texas some few years since. In ad- 

 dition to this, all previously recorded species for that State were 

 collated, and the result was the determination of a total of 149 

 species as all which, up to the present, have been recorded. This 

 number is exceedingly small, and only serves to prove how very 

 little is known of the mycologic flora of a state which probably is 

 as rich in fungi as South Carolina. 



The following twenty-five species are all that are absolutely new. 



Corticium carnefm, Berk. Sf Cooke. — Effusum, membrana- 

 ceum vel subceraceum, ochraceo-carneum, ambitu albo-fibrillo- 

 sum ; hymenio tenui, subglabro, laevi, siccitate rimoso. 



On logs. Houston, Texas {Rav. 78). 



The hymenium gives rise to fusiform rough cysts, such as are 

 found in Corticium cinereum, which project above the surface, but 

 do not occasion any velvety appearance, either to the naked eye 

 or under a lens. 



Cyphella convoluta, Cooke. — Sparsa ; pileo cupuliformi (1-2 

 m. m.) demurn applanato, margine membranaceo, involuto, extus 

 albo, intus carneo-rubro ; sporis oblongis ('007 m. m.). 



On trunks. Houston (Rav. 295). 



Phoma hystekiieobme, Cooke. — G-regaria ; peritheciis atris, 

 elongatis, hysteriiformibus, ad basin applanatis ; sporis ellipticis, 

 binucleatis, hyalinis (01-012 m. m.). 



On herbaceous stems. Galveston (Rav. 224). 



Phlyct^na smilacis, Cooke. — Tecta, minuta, brunnea, dense 

 gregaria, pauce elevata ; sporis filiformibus, elongatis, ad apicem 

 curvulis (-02-025 m. m.). 



On Smilax. Houston (Rav. 208, 209).
