Fungus Flora of ML Hood 135 



Leptonia subeuchroa, sp. nov. — Pileus 1.5-2 cm. broad, 

 subpliant, convex, subumbonate, "dark purple-drab" (R.), 

 densely hairy-scaly, even on margin which is at first incurved; 

 flesh thin, concolor towards cap surface, whitish towards gills. 

 Gills adnate, subventricose, rather broad, close (or subdistant 

 in age), pure white at first, becoming ''seashell pink" (R.), 

 edge concolor, entire. Stem 2-3 cm. long, 1.5-2.5 mm. thick, 

 straight or curved, equal, ''dark madder blue" (R.), glabrous 

 and even, naked at apex, stuffed to hollow, whitish within. 

 Odor not noted. Spores almost even, obscurely angled, elHp- 

 soid-almond-shaped, bright pink under microscope, 8-9(11) X 

 5.5-7 m; basidia 4-spored, about 45 X 7 fx; cystidia none; sterile 

 cells on edge of gills indistinct. 



On mossy log, in forest of cedar, hemlock and maple. Gre- 

 garious. Mt. Hood, Oregon. October 16. Collected by C. H. 

 Kauffman. 



This species stands apart from all its relatives by its ob- 

 scurely angular spores. As to individual species, it differs from 

 L. placida by the absence of black squammules at apex of stem; 

 from L. suhplacida and many others, in spore-size and color; 

 from L. euchroa in the white young gills; from L. chalybea by its 

 habitat and color; and from L. chloropolia and L. lazulina by 

 the non-striate margin of the pileus. 



Leptonia trivalis, sp. nov. — Pileus 2-4 cm. broad, subpliant, 

 flattened-convex, finally plane and margin elevated, obscurely 

 depressed-papillate, subviscid from a subgelatinous, subseparable 

 pellicle, glabrous, pellucid-striatulate when fresh, ''sayal brown" 

 (R.), slowly fading; flesh concolor, fading, subhygrophanous, 

 margin at first incurved. Gills adnate-seceding, rarely with 

 decurrent tooth, close, rather narrow, 2-4(5) mm., white at 

 first, "light pinkish cinnamon" at maturity, edge entire or 

 suberose. Stem 4-8 cm. long, 2-4 mm. thick, equal, elastic, 

 cortex cartilaginous, toughish, hollow, flexuous, even, very 

 glabrous, easily splitting lengthwise, hyaline- white. Odor and 

 taste none. Spores globose, obscurely angular, pale under 

 microscope, 7-8 // diameter; basidia 4-spored, 25 X 8-9 /x; 

 cystidia none; sterile cells on edge of gills indistinct.
