11. Hypocrea pallida Ellis & Everh. Jour. Myc. 2: 65. 1886 



Stroma effused, overspreading and entirely covering the hy- 

 menium of the host, cottony but giving rise to an even stratum 

 equal in diameter to that of the host, at first pallid or pale yellow 

 or often with a slight tinge of rust-red, paler near the margin; 

 perithecia thickly scattered and partially immersed in the sub- 

 stratum with the ostiola projecting, amber, darker than the sub- 

 stratum; asci cylindrical, 50-75X4-5 niic. becoming i6-spored 

 by the separation of each original spore into 2 subglobose cells ; 

 spores 3-4 mic. in diameter, subglobose or slightly cubical. 



On the hymenium of species of Tyromyces. 



Type locality : N. Jersey. 



Distribution : N. Jersey to Canada. 



Specimens examined: Connecticut (no name); N. Jersey, 

 Ellis (various collections) ; Prince Edward's Island, Canada, 

 A^acoun. 



Hypocrea aurantiaca Peck agrees with this species in habitat 

 and general morphological characters but seems to differ in 

 possessing a decidedly orange color. The various specimens ex- 

 amined would seem to indicate that the difference in color is due 

 to a difference in age as some of the present species examined 

 show a trace of rust-red approaching that of H. aurantiaca, and 

 one specimen in the Ellis collection is labeled in the handwriting 

 of Mr. Ellis, H. pallida var. aurea. Field observation is necessary 

 in order to determine whether the two species are identical but 

 for the present they are allowed to stand. 



12. Hypocrea latizonata Peck; Ellis & Everh. N. Am. Py- 



renom. 79. 1892 



Stroma consisting of a white subiculum which forms a band 5 

 mm. in diameter, entirely surrounding the outside of the cups of 

 the host ; perithecia thickly gregarious, immersed, with the ostiola 

 protruding, darker colored, brownish-black; asci cylindrical, 60- 

 75 mic. long, becoming i6-spored by the separation of each 

 original spore into 2 subglobose cells ; individual spores 3-4 mic. 

 in diameter, the lower of each pair slightly longer {pi. 20, 

 f.9-10). 



On the outside of the cups of Cyathus striaHis. 

 Type locality: Ohio. 



Distribution : Known only from the type locality.
