Medücock, George G., Studies upon some Chromogenic 

 Fungi which discolor Wood. (Seventeenth Annual Report 

 Missouri Botanica! Garden. p. 59—114. Plates 3 — 12. Sep- 

 tember 27, 1906) 



The author has studied a number of chromogenic fungi which 

 discolor wood. He divides these into thrcegroups: the wood bluing 

 fungi, represented by the genus Ceraiosiomella : V/ood blackening 

 and wood browning fungi, represented by the genera Graphium, 

 Hormodendron, Hormiscium ; and wood-reddening fungi, represented 

 by the genera Penicillium and Fusarium. The author made careful 

 cultural studies of a large number of species, and gives in detail, 

 descriptions of the mycelia, conidial and perfect stages. The follo- 

 wing species are described as new : Ceratostoniella Schrenkiana, 

 Ceratostomella capillifera, Ceratostomella pluriannulata, Ceratosto- 

 niella niinor^ Ceratostomella exigua, Ceratostomella moniliformis, 

 Graphium ambrosiigerum, G. atrovirens, G. aureum, Hormodendron 

 griseum, Hormiscium gelatinosum. 



In addition to these new species he refers to the following: 

 Ceratostomella pilifera (Fr.) Winter, C. echinella E. and E., Graphium 

 enmorphum Sacc, G. smaragdinum (A. and S.) Sacc, G. rigidum 

 (Pers.) Sacc, G. album (Corda) Sacc, Hormodendron cladosporioides 

 (Fres.) Sacc, Penicillium aureum Corda, P. roseum Link, Fusarium 

 roseum Link. 



Hedgcock discusses the causes for discoloration of wood fiber 

 and finds that the cause of stain in Ceratostomella is due to the 

 color of the hyphae of the fungus. The same is true of the species 

 of Graphium, Hormodendron and Hormiscium. The species of Peni- 

 cillium discolor the wood by secreting a soluble red or yellow pig- 

 ment which is absorbed by the wood fiber, while the species of 

 Fusarium discolor the wood both because of the presence of co- 

 lored hyphae and by the secretion of a pigment. A key to the 

 species of wood-coloring fungi is added. The conidial and perfect 

 stages of the various fungi described are illustrated on ten plates 

 and three text figures. von Schrenk.
