Jan. 1908] First Report on Guatemalan Ascomycetae 3 



slightly rounded behind, adnexed, pinkish or pale flesh color 

 when mature; stem equal, glabrous, hollow, whitish; spores 

 broadly elliptic or subglobose, 6-7 /* long, 5-6 /* broad. ' 



Pileus 2-2.5 cm. broad; stem about 2.5 cm. long, 2 mm. 

 thick. Ellis, Massachusetts. November. G. E. Morris. 



This species is peculiar in its glabrous pileus and broad 

 shallow umbilicus. This is likened by Mr. Morris to the con- 

 cavity of a kid-glove fastener. 



Pistillaria batesii Peck n. sp. 



Densely gregarious, forming elongated almost compact 

 patches on the stem of the host plant; club soft, fleshy, ovate 

 or oblong, obtuse, sessile or narrowed below into a very short 

 stem, pallid when moist, grayish pink and pruinose when dry, 

 .5-1 mm. long; spores filiform, straight or curved, hyaline,' 

 10-20 II long, 1-2 ju, broad. 



Stems of purple poppy mallow, Callirhoe involucrata. Red 

 Cloud, Nebraska. July. Rev. J. M. Bates. 



This is one of the smallest species of the genus, and is 

 parasitic on the under side of the creeping stems, appearing first 

 near the base and advancing toward the growing point. I wish 

 it to commemorate the name of its discoverer. Albany, New 

 York. December 2, 1907. 



DR. REHM'S FIRST REPORT ON GUATEMALAN 

 ASCOMYCETAE.* 



W. A. KELLERMAN. 



Collections of Fungi in Guatemala the past three years 

 mclude a large number of Ascomycetae. A dozen of these were 

 placed in Dr. H. Rehm's hands recently and I am permitted to 

 publish below his determinations, comments and descriptions of 

 new species. 



The specimens represent widely distant and diverse regions 

 of that Republic, as well as great extremes in altitude; the De- 

 partamento, as well as exact locality in each case is. indicated. 



All of the remaining ascomycetous material secured will be 

 submitted to Dr. Rehm, and the 'results will be published in later 

 jSfumbers of this Journal.
