Soc. i: 159. 1857 



Stromata 1-3 cm. high ; stem 3-4 mm. thick, simple or divided 

 into 2-4 short branchlets, even, smooth, brown ; head 1-2 cm. 

 long, thicker than the stem, cylindic-ovoid, dull brownish-purple 

 or flesh-colored, minutely rough with the slightly protruding 

 necks of the perithecia; asci elongate, narrowly cylindric, capitate, 

 tapering below into a long, slender pedicel ; spores arranged in a 

 parallel fasicle, slightly curved, filiform, hyaline, becoming many 

 septate, 100-120 X i niic, the segments 1.5 mic. long {pi- 54, f. 5). 



On moist rotten logs, growing from the larvae of some coleop- 

 terous insect. 



Type locality : South Carolina. 



Distribution : Known only from the type locality. 



Illustration : Jour. Linn. Soc. i : pi. i. 



Berkeley in his original description of this species savs : " The 

 extremely minute articulations or sporidiola, wathout any other

i: 159. 1857 



Stromata usually solitary, 3-8 cm. high, consisting of a sterile 

 stem and fertile head ; stem 2-5 cm. long, grooved or furrowed, 

 brownish, becoming nearly black on drying, about 2-3 mm. in 

 diameter ; fertile head terminal or more rarely with a sterile apex 

 or with the perithecia in patches, with bare, sterile spaces be- 

 tween ; perithecia partially immersed, becoming almost entirely 

 superficial, giving the fertile portions a very rough appearance, 

 similar in color to the stem ; asci very long, cylindric ; spores fili- 

 form, nearly as long as the ascus, breaking into segments 4-5 mic. 

 long {pi. 54, f. 10). 



Springing from the larvae of coleopterous insects. 



Type locality : South Carolina. 



Distribution: South Carolina to Pennsylvania (and Iowa?). 



ExsiccATi : Rav. Fungi Car. 4: 28. Other specimens ex-
