H. polyporoidea, B. & C. Grev. IV, p. 15. 



"Fawn-colored. Peritheciafree, tomentose, with a naked ostiolm 

 seated on a pale crust, here and there elevated and thinner towan 

 the margin. A very curious species." Cooke, in Grev. 1. c, givi 

 the hyaline, subglobose cells of the sporidia as 5 /i in diam/ 



H. snlphnrea (Schw.) . 



Sphisria sulphurea, Schw. Syn. N. Am. 1221. 



"Rather thin, subcarnose, at length horn-like in texture (whe 

 dried), the thin, partially free margin variously lobed', sulphur-colo 

 white within. Perithecia crowded, globose-depressed, immersed, dirt; 

 yellow. Ostiola concolorous, papillate, situated in little pit-like d 

 pressions of the otherwise smooth surface. On bark; rare; separab! 

 when fresh, subrotund, 1^ inches across." In Grev. 1. c, the globos 

 cells of the hyaline sporidia are said to be 5 /j in diam.

Perithecia pale horn-color, subglobose (250 /i), immersed in 

 rather scanty, loose, white tomentose mycelium (stroma), which ove 

 spreads the surface of the pores and covers the sides of the perithec 

 themselves, leaving their apices and papilliform ostiola bare. As 

 cylindrical, 65-75 x4r-4| /i, containing eight oblong-elliptical, 2-cene( 

 hyaline sporidia, the cells subcubical or nearly globose, 3 /i diam. an 

 readily separating. The upper part of the perithecium collapses whe 

 dry, and, in old or weather-beaten specimens, the tomentose stroff 

 disappears, leaving the perithecia sessile on the pores. We have see 

 no specimens of H. 'polyporoidea, B. & C., but our .species will \ 

 distinct from that, in the absence of any crust-like stroma and in i 

 smaller sporidia. It was first found in October, 1880, and again i 

 October, 1886. 



Parasitic on decaying Polyporus ccssivs, Newfield, N. J. 



;^pccimens found by Dr. Macoun in Prince Edward's Island, c 

 Pol. ckio/ieus, Fr., agree perfectly with the Xewfield speciniens, on] 

 there is an orange-colored mycelium which stains the Polyporus with: 

 of a fine, light yellow.
