BURT — HIGHER FUNGI OF THE HAWAIIAN ISLANDS 183 



Fomes hawaiensis Forbes in Lloyd, Myc. Writ. 4: Syn. Femes, 



260, 287. 1917. 



Type: Forbes, 2.L probably — a portion in Mo. Bot. Gard. Herb. 



" Color bay, pore mouths 150 mic, otherwise as Fomes senex. 

 Surely only a form, but of quite distinct form and pores one- 

 half larger. Based on a collection from C. N. Forbes, Hawaii.' ' 



Hawaii, C. N. Forbes (on Acacia) 1075.H, 1077.H, 1079.H, 

 1080 H, 1081.H; Kauai, C. N. Forbes, 21; Lanai, C. N. Forbes, 

 2.L; Molokai, C. N. Forbes, 762.M, 1624.M; Hawaiian Islands, 

 C. N. Forbes, 9-S, 11-S, 1076, 1629, 2116, and F. L. Stevens, 



109, 648, 876. 



The above specimens show this species more triangular in 

 section than F. Korthalsii and having a maximum thickness 

 at the base of up to 9 cm. in specimens 5-8 cm. broad, with 

 margin acute; pores about 4 to a mm., of the same color as the 

 context and both between Brussels brown and antique brown; 

 setae 30-35 X6^; spores becoming colored, subglobose, even, 

 43^-5 X 4 ix. The coloration of all parts and the setae and 

 spores are the same as in F. Korthalsii. 



Fomes fasciculatus Burt, n. sp. 



Type: in Mo. Bot. Gard. Herb. 



Fructification narrowly effuso-reflexed or resupinate, 8-15 mm. 

 thick, resupinate portion up to 10 cm. in diameter, the reflexed 

 margin 5-10 mm. broad, becoming dark quaker-drab of Ridgway, 

 glabrous, not shining, horny, the extreme margin light buff; 

 context and tubes drab; tubes stratified; mouths light buff to 

 pale drab-gray, circular, 6-8 to a mm. ; hyphal fascicles present 

 in the hymenium, no setae nor cystidia ; a few loose spores hya- 

 line, even, 4 X 3 y.. 



The external aspect and coloration are somewhat suggestive of 

 Fomes fraxinophilus . The hyphal fascicles, to which the specific 

 name refers, are similar to those in the hymenium of Poly- 

 stictus hirsutus and are a constant and distinctive specific char- 

 acter in many other Polypores, although not heretofore recorded 



for this family. 



On dead Koa tree, Kauai, A. A. Heller, 2677, type (in Mo. 

 Bot. Gard. Herb., 4588), distributed by Heller under the her- 

 barium name Poria albogrisea; Lanai, G. C. Munro, 1.
