TYLOSTOMA BERKELEYII (Plate 84). Peridium colored. 

 reddish brown. Cortex nature of a sand-case, separating usually imper- 

 fectly and much more strongly adnate than the previous species. Mouth 

 surrounded by a few granular fibrils (the same as the previous plant). 

 Stem slender, dark reddish, often slightly scaly, usually strongly sul- 

 cate, striate. Capillitium light colored with slightly swollen often oblique 

 septa. Spores 5-6 mic., granulose. 



This plant occurs in the southern United States, and is the species 

 referred to in American literature as Tylostoma fimbriatum, surely a 

 misnomer, for no similar plant grows in Europe. It was Berkeley, I 

 think, who first thus determined the American plant, and hence we 

 name it in his honor. f This species corresponds to the European only 

 in its mouth and spore characters. It differs in being a colored plant 

 and having a large head and slender stem. A splendid illustration of 

 the plant was given by Petri (Ann. Mycologici, 1904, Plate 6) under 

 the name of Tylostoma fimbriatum, and drawn, we think, from American 

 specimens.

TYLOSTOMA CYCLOPHORUM (Plate 85). Periclium light 

 brownish color, with a raised, shield-shaped, fibrillose mouth. Cortex 

 thin, separating perfectly, leaving the peridium smooth. In old plants 

 very little of the cortex remains attached at the base of the peridium. 

 Stem slender, dark, with a strong, fibrillose, dark cortex, which becomes 

 lacerate and strongly persists at the base of the peridium, forming a 

 lacerate collar. Capillitium colored, thick (3-4 times diameter of spores), 

 with thick walls and numerous slightly swollen, colored nodes. Spores 

 4-5 mic., granulose. 



These specimens were received from Miss B. Stoneman, South 

 Africa. The plant is very similar to Tylostoma Rickii of South America 

 in general apearance and particularly in the strong, fibrillose cortex of 

 the stem remaining as a conspicuous collar at base of the peridium. 

 It differs in all its other characters.

t The custom of naming plants after authors who misname them is a kind of 

 back-handed compliment frequently handed out in mycology.
