feltlike. The thickness of the hymenium-producing portion is 2 to 

 4 mm, of which the subiculum sometimes represents as much as 

 half. This latter is soft and feltlike and brown in color. The 

 tubes are i to 2 mm long. Their mouths are angular, irregular or 

 slightly daedaloid and measure 1 to 2.5 to a millimeter. The dissepi- 

 ments are at maturity rather thin and entire or slightly denticulate. 

 There is no sheen or silkiness to the hymenium. 



The spores are broadly ovoid or broadly ellipsoidal to subglobose, 

 hyaline and measure 5 to 7 by 3 to 5 /x (plate 21, figure 5). There 

 are no cystidia (plate 21, figure 2). The hyphae are of two gen- 

 eral sizes. Those of the sterile subiculum are the larger and are 

 heavy-walled, brown in color and with evident cross walls and 

 little or no branchings (plate 21, figure 4). Their diameter is 5 to 

 7 /.i. Those of the trama are considerably smaller, 3 to 6 /u, in 

 diameter. Some of these are brown and a few are nearly or quite 

 colorless. Branching is more frequently found in these than in 

 \he hyphae of the subiculum. and cross walls are not uncommon 

 (plate 21, figure 3). These hyphae are more flexuous and some- 

 what thinner walled than those in the subiculum. 



The species apparently has no near relatives that are at all com- 

 mon in this country. A collection has been recently received from 

 E. T. Harper, collected on an arbor vitae log at Neebish, Michigan, 

 October 191 7. This specimen has persisted for three years, form- 

 ing a new layer of tubes each year. Lloyd reports (letter no. 63, 

 p. 16) a collection from Wisconsin by Dr C. J. Humphrey. 



Redescription. Annual or reviving for two or three years, easily 

 separating, effused for several centimeters, general color brown; 

 consisting at first of a soft brown subiculum on w T hich pores are 

 developed ; subiculose margin broad, sterile, feltlike, clay color to 

 ochraceous tawny ; subiculum conspicuous, brown, up to 2 mm thick, 

 soft and floccose ; tubes 1 to 2 mm long, their mouths near cinnamon 

 or ochraceous tawny, angular to irregular or slightly daedaloid, 

 averaging 1 to 2.5 to a millimeter, with rather thin and entire or 

 denticulate dissepiments ; spores broadly ovoid to broadly ellipsoidal 

 or subglobose, hyaline, 5 to 7 x 3 to 5 /x; cystidia none; hyphae of 

 margin thick-walled, brown, 5 to 7 n in diameter, simple, cross walls 

 rather numerous, no clamp connections ; hyphae of trama more 

 flexuous, brown or sometimes hyaline, 2.5 to 5 /x in diameter, other- 

 wise as above. 



Creeping over mosses, decayed wood, etc.

 Peck at Freeport, N. Y., and by E. T. Harper at Neebish, Mich.
