384 NATURAL SCIENCES OF PHILADELPHIA. [1894. 



SpJurropsis. Hyphse tufted, yellowish- brown (under the microscope), 

 septate, erect, nearly straight or subundulate, 80-100 x 4-5//. 

 Conidia obovate or obpiriforra, 3-5-septate and muriform, brown, 

 24—38 X 15-20//, terminal, sessile. Conidia also occur subcubical or 

 subglobose, 15-20// diara. with 2-septa crossing each other at right 

 angles. 



Sporodesmium fructigenum E. & E. 



On decaying apples. Las Cruces, New Mexico, Oct. 1893 (E. W. 

 Wooton). 



Appears like a thin, dark colored, velvety coating, appearing first 

 around the stem end but finally spreading over the greater part of 

 the apple Conidia subglobose or elliptical, stipitate, yellowish and 

 uniseptate at first, finally nearly opake and muriform, 12-26/'. in 

 the longer diameter. 



The conidia have a berry- like structure like that of S. Rauii E. 

 & H. or S. moriforme Pk. The pedicels, which are 12-15 x S/Jt are 

 deciduous. 



Sporodesmium subcupulatum E. & E. 



On dead Sambucus melanocarpa, Cameron Pass, Colorado, July, 

 1894 (C. F. Baker, No. 236, partly). 



At first tuberculiform, minute, i—k mm. diam. , erumpent and 

 surrounded by the ruptured epidermis, becoming concave and often 

 oblong 1-2 mm. long, o-| mm. wide, slaty black; conidia olivaceous, 

 muriform, subglobose, 10-15// diam., or subelliptical or clavate- ob- 

 long, 20-30 X 10-12//, sessile or with a short, thick pedicel. In the 

 concave stage the acervuli and conidia are paler. 



Sporodesmium tuberouliforme E. & E., n. sp. 



On dead stems of Sambucus racemosa, near Rabbit Ear Pass, N. 

 W. Colo., alt. 10,000 ft., July, 1894 (Prof C. S. Crandall, No. 



15). 



Sporodochia tuberculiform, black, inside and out, about 1 mm. 

 diam., flattened above. Conidia irregular in shape and variable in 

 size, subcubical, subglobose, subelliptical, consisting of 2-20 sub- 

 globose cells variously conglomerated so as to form the conidia 8-20// 

 diam. 



The tubercular mass consists almost entirely of the compacted 

 conidia which are more perfectly developed in the superficial layer.
