REPORT OF THE STATE BOTANIST I917 IKJ 



Notes. This is an extremely unsatisfactory species from the 

 standpoint of the type collection, and no other material is avail- 

 able. In the box of type specimens are many small bits of rotten 

 wood some of which are covered by the fungus that for the most 

 part one would hardly refer to the pore fungi at all. There are 

 only a few small pieces that show the nature of the hymenium. 

 The fragments that are mature suggest an Irpex (Hydnaceae) 

 rather than a Daedalea, and in some specimens there project 

 isolated rounded teeth from the substratum. The writer is 

 inclined to believe that the fungus does not belong in this group, 

 but since it was so described by Peck it will be presented here. 



The largest fragments of fruiting bodies are scarcely more than 

 1 cm broad, but some fragments showing no hymenial configura- 

 tion are somewhat larger. These last mentioned have the appear- 

 ance of a species of Corticium (plate 23, figure 1). The color 

 of the fungus is now pinkish buff or cinnamon buff all over, 

 but was described by Peck as sulphur yellow in the fresh 

 plant. The surface of the fructification is very uneven, following 

 the inequalities of the wood. The thickness of the fungus, includ- 

 ing the length of the teethlike projections, is not more than a 

 millimeter, and where no teeth are present it is extremely thin. 

 The spore-producing layer covers the surface of what appear to 

 be platelike teeth or in some cases awl-shaped projections. These 

 teeth are for the most part connected at the base as in Irpex, or 

 as might happen if the dissepiments were much torn or split. 

 The presence of isolated teeth, however, seems to favor the idea 

 that the proper place for the species is among the Hydnaceae. 

 The fungus was growing in part on a vertical substratum which 

 would exaggerate the sinuous character of the hymenium. 



Some parts of the fungus are mature and spores are produced 

 in abundance. These are broadly ellipsoidal or globose, hyaline, 

 and measure 4 to 6 fi in globose forms. The ellipsoidal spores 

 are 5 to 6 //, long and 4 to 5 /n broad (plate 23, figure 4). 

 Often a slight apiculus is visible, and frequently the spore con- 

 tains a large hyaline oil globule that practically fills it. The 

 basidia are 5 to 6 fx in diameter. The trama and subiculum are 

 fairly compact and composed of colorless thin-walled hyphae that 

 are 2.5 to 6 /1 in diameter. They are much branched and cross 

 walls are rather conspicuous and fairly abundant. A large per- 

 centage of these walls have clamp connections, but not all of them 

 (plate 23, figure 3).
