Doubtful and Excluded Species 



Dermatea crypta Cooke, Grevillea 16: 70. 1888. Ellis states: "This ap- 

 pears to be the same thing I have published in Torr. Bull, as Dermatea olivacea 

 on Ilex glabra Newfield, N. J. 1875". 



Dermatea cucurbitaria Cooke; Ellis, N. Am. Fungi 6S; Tryblidium cucurbi- 

 taria Rehm, Ber. Naturh. Ver. Augsburg 26: 78. 1881. This is regarded as a 

 Tryblidium. 



Dermatea Cydoniae Schw. Trans. Am. Phil. Soc. II. 4: 237. 1832. On 

 Cydonia. According to Groves, this is not a discomycete. 



Dermatea Eucalypti Cooke & Hark.; Cooke, Grevillea 9: 130. 1881. 

 This according to Groves is apparently not a Dermea but it is impossible to 

 place it. 



Dermatea ferruginea (Cooke & Ellis) Rehm, Ann. Myc. 2: 353. 1904; 

 Patellaria ferruginea Cooke & Ellis, Grevillea 5:91. 1 877. Groves states that 

 this is probably a Pezicula but its identity is uncertain. Ellis, N. Am. Fungi 

 148 under this name is on stems of Desmodiiim. 



Dermatea olivacea Ellis, Bull. Torrey Club 6: 133. 1876. According to 

 Groves this is probably a Pezicula. The species, however, needs more study 

 from fresh material. It was originally reported on Ilex glabra. See N, Am. 

 Fungi 851. The name as pointed out by Groves is invalid having been previ- 

 ously used. 



Dermatea puberula Durand, Jour. Myc. 10: 101. 1904. This according 

 to Groves is not a Dermea and its position is uncertain. 



Dermatea Xanthoxyli Peck, Ann. Rep. N. Y. State Mus. 31: 47. 1877. 

 This is Thyronectria pyrrhochlora (Auersw.) Sacc.
