2. S. splendens Rest., Men., p. 195 (1875). Plasmodium 
creamy white, on fir stumps, etc., maturing at the place of 
emergence. Total height 6 to 12 mm. Sporangia cylindrical, 
obtuse, stipitate, purplish-brown, at first closely fasciculate. 
Stalk black, shining, slender, 1 to 4 mm. long, rising from a well- 
developed silvery or purplish hypothallus. Columella reaching 
to near the apex of the sporangium, rigid, sometimes weak and 
flexuose in the upper half. Oapillitium of purplish-brown 
threads, the principal branches varjdng in intricacy, but usually 
springing at distant intervals from the columella, at first almost 
simple, suddenly branching to form a sviperficial net with 
smooth, rounded, variously shaped meshes, 20 — 100 /a wide. Spores 
pale reddish-purple, nearly smooth, or minutely and closely 
warted, 7 to 9 ju, diam. — Stemonitis Mai'gani Peck, in Bot. Gaz.,

a. genuina : superficial net of capillitium complete, with 
rounded meshes, 20 to 70 ju. diam. 
(3. Webberi : sporangia stiff, erect ; superficial net complete, 
Avith meshes 80 to 100 /a wide. 
y. flaccida : sporangia weak, adhering ; capillitium lax, scarcely 
forming a superficial net ; membranous flakes of sporan- 
gium-wall always present. 
8. confluens : sporangia confluent, without superficial net. 
Plate XLIII., A.— a, h, e, sporangfia, a. genuina, x 2 ; d. capillitium of 
Rostafinski's type from Texas, x 180 ; e. capillitium with membranous 
expansion, from Rostafinski's type (Cuba), x 180; /. capillitium of type of

the same, with membranous expansion, x 180 (England) ; i. spore, x 600. 
Var. 8. corresponds with the confluent form of S. fusca ; the capilli- 
tium forms a dense intricate network, connected with indefinite 
branching columellce, with frequent membranous saucer-shaped ex- 
pansions, without stalks or superficial net. The specimen from N. 
CaroUna (Curtis, 419), named Lachnoholus cribrosua (B. M. 935) appears 
to be this variety, and the note by Fries following his description of
