R. 1-30 cm., purple, becoming blockish when dry, broadly effused; 

 margin concolorous. Hymenium concolorous, undulately plicate. Flesh 

 pale purplish, gelatinous, then horny, finally collapsing into a thin 

 film. Spores white, elliptical, depressed on one side, laterally apicu- 

 late at the base, 8-10 x 4-5-5-5/z; basidia clavate, 15-18 x 6-5-7 /x, 

 with 4-sterigmata ; sterigmata at first oblong, granular inside, 15 x 

 3-3'5/i, at length collapsed, up to 20/x long. Subhymenial hyphae, 

 6-8/x in diam., basal hyphae pale purplish, 4/x, in diam. Pine needles, 

 at the base of a stump. Nov. Rare. 



CALOCERALES. 



Basidia cylindrical, becoming forked with two long, pointed sterig- 

 mata. Hymenium fully exposed from the first. Spores always be- 

 coming septate on germination, and producing from each cell either 

 one sporidiolum, or a bunch of conidia.

Dacryomyces Nees. 

 (Sd/cpvov, a tear; fAvtcr/s, fungus.) 



Receptacle gelatinous, or subgelatinous, homogeneous; globose, 

 subglobose, tuberculate, often becoming cup-shaped, and sometimes 

 flattened, sessile, rarely stipitate or substipitate. Hymenium smooth, 

 wrinkled, or folded. Basidia with two long, pointed sterigmata. Spores 

 white, or yellowish, oblong, cylindrical, ovoid, subelliptical, or ovato- 

 triangular; simple, transversely septate, or muriform. Receptacles 

 producing conidia, globose, consisting of radiating, septate, monili- 

 form threads. Growing on wood.
