CHROMOGENIC FUNGI WHICH DISCOLOR WOOD. 71 



or gray at the apex, but smooth throughout measuring 

 1 mm. to 1.7 mm. in length by 15ft to 25ft in diameter 

 and surmounted when mature by a terminal friuge of 

 bristles 15ft to 25ft in length and tapering from 4ft at the 

 base to 1ft at the apex, being hyaline throughout (pi. 3, f. 

 3). The asci are elavate(?), bearing biseriate spores 

 which are hyaline, curved or straight, elliptic to cylindri- 

 cal, and which are ejected in the open air in a globular mass 

 at the terminus of the beak. 



Since writing the above, co-type material of C. echinella 

 in the herbarium of the Missouri Botanical Garden has been 

 examined. The perithecia are probably as described by 

 Ellis and Everhart,* but they have persistent asci which 

 contain brown two-celled ascospores, placing the fungus in 

 the specimen under another genus. This indicates that at 

 least a mistake was made in a portion of the material sent 

 out as type specimens if not in the description. 



Ceratostomella capillifera n. sp. 



The wood of Liquidambar Styraciflua L. is an excellent 

 pallidum for a large number of fungi, and lumber made 

 from this tree, when in piles, soon becomes thoroughly 

 stained either blue or black by the growth of a number of 

 species of wood-discoloring fungi. Among these was 

 found quite commonly a species of Ceratostomella which 

 is closely related to C . pilifera, but differs in the length 

 of the beaked ostiolum, the length of the terminal bristles 

 and the shape and size of the conidia and ascospores. 

 The following characters obtain with pure cultures : — 



Mycelium. 



Cultures of either conidia or ascospores sown on pine- 

 decoction agar germinate quickly, forming a diffuse, white, 

 hyaline, septate mycelium, which in less than two days
