1905] ATKINSON—HYPOCREA ALUTACEA 413 
acters of this genus and species are so remarkably like those of 
Hypocrea alutacea that it may be well here to give a translation both 
of the generic and specific diagnosis. 
PODOSTROMA n. gen.—Character of the Hypocreaceae. Stroma stipitate, 
davate, erect, entomogenous, fleshy, bright colored. Perithecia imme i 
he stroma. Asci cylindrical, 16-spored. Spores sphaeroidal, hyaline. Para- 
physes none. 
Pod. leucopus n. sp.—Stromata solitary. Clavula bearing the perithecia 
obovoid to oblong, alutaceous-pallid, about 6™™ long and 4™™ stout. Stipe 
equal, terete, flexuous, about 5°™ long and 2™™ stout, white. Perithecia in the 
periphery, spheroidal, immersed, opening by a pore. Asci cylindrical, sub- 
sssile, about 754. Spores 16, monostichous, spheroidal, hyaline, 2-3 # in 
diameter. On larva of certain putrid insects among mosses in coniferous woods, 
Syrjaas, October. 
The specimens of no. 246 Rabenh. Fungi Europ. Ex. in the her- 
barium of the Botanical Department here represent very well in form 
and size the Podostroma leucopus described by KARSTEN. The 
Plants are slender when dry, 3°™ high, the stem less than 1™™ in 
diameter and was likely not more than 2™™ when fresh. The 
cayula is obovoid, about 3.5" long a trifle over 2™™ in diameter, 
and was very likely stouter when fresh. The plants of no. 132 
Rabenh. Fungi Europ. are much stouter, the stem more than 2°" 
i diameter when dry, short, and the clavula elongate and tapering 
gradually into the stem. ‘The spores in no. 246 are mostly cuboidal 
in the specimen examined, and the asci show that they are young: 
Many of the asci give the appearance of having sixteen equal sub- 
cuboidal spores. But occasionally, where they are 4 little older, 
“ery alternate one is slightly elongated and narrowed, so that 1t Js

“entent divided into eight parts, and then occasionally one of these 
Young spores is divided into two cells. ‘This indicates clearly that 
here are eight spores. The second division is so prominent and the 
“onstriction so deep it gives soon the appearance of sixteen spores. 
t would appear that in the later growth of the spores the infenot 
“gment elongates slightly at the expense of its diameter. The 
‘Pecimens collected at Ithaca show the same character from sa 
a when asci are just maturing the spores. The pee
