 No. 3, p. 22. 



F'ruclification very soft, white, thick, resupinate, loosely 

 adherent, margin often separating, but scarcely reflexed, or 

 in the dry state sometimes incurved. Hymenium white or 

 at length somewhat cream to pallid. Pores usually angular, 

 variable in diameter. Hyphae septate, with clamp- 

 connections, 2-4/x wide. Basidia 4-spored, 20 x 5/z. Spores 

 ellipsoid, 4-6 x 2-3/^1. 



On rotten coniferous wood. 



The above is Romell's description, which agrees very 

 well with a plant found several times near Weybridge on 

 pine wood and bark, and apparently fairl}- common 

 there. It is rather thick and spongy, but so fragile and hard 

 to gather in good condition that although it must have been 

 seen repeatedly it has probably been put aside as unnameable. 



Romell adds, " Some specimens which seem to belong to 

 this species are partly or totally reduced into a floccose- 

 pulveraceous state of sulphurous or pallid colour, which 

 contains abundant subglobose or ellipsoidal, apparently 

 asperulate, i-guttulate chlamydospores of 5-7.5x4-5//, not 

 unlike those of Ptychogaster albus, though more hyaline." 



This conidial stage is also very evident in the Weybridge 

 specimens. Sometimes the conidia occur only at the margin, 

 at other times the whole fungus 



appears to be a pale yellow ^ c:;;^ rs(^
