Sero autumno ad Morum albam (Val di Sole) et Popu- 
lum pyramidalem (Tridenti) caespitose, et quotannis obvius. 
Plurimis notis ad Myc. laevigatam Lasch. accedit; at minus 
rigidus, et potius Mycenae lacteae Pers. et luteo-albae Bolt 
affınis, juxta quas in systemate locandus. 
101. Mycena caesio-livida Bres. n. sp. 
Pileus submembranaceus, e convexo campanulatove ex- 
pansus vel revolutus, subirregularis, glaber, hygrophanus, 
pellueide striatus, e livido-caeruleo caesiove incarnato-lividus, 
8—12 mm latus; lamellae ventricosae, subdistantes, postice 
rotundato-subliberae, ex albo roseae, demum livido-incarnatae, 
venoso - conjunctae; stipes brevis, fistulosus, e pruinato 
glabrescens, teres vel compressus, e caesio caeruleove lividus, 
basi radicato-strigosus, 1—1'Ja cm longus, 3—4 mm crassus, 
Caro concolor, inodora et insapora. Sporae ellipticae, 8-10 
x 5'a—6 mmm; basidia clavata 30-35 >= 6—8 mmm. 
Autumno, ad cortices muscosas laricis gregatim obvius, 
Val di Sole. Mycenae zephirae Fr., quacum pluries comparari 
contigit, affinis, at optime distinctus.

Pileus submembranaceus, e convexo -subeampanulato 
expansus, papillatus, striatus, fusco-badius, siceus subeinnamo- 
ıneus, 2—3 cm latus; lamellae subconfertae, ex albido-livido 
carneo-fuscae, postice sinuato-adnatae; stipes fistulosus,

10—11 x 6—7 mmm; basidia clavata 30—35 >= 10—12. 
Aestate, locis graminosis aprieis, vel in nemoribus fron- 
dosis frequenter obvia. A Nolanea mammosa Linn. nostro 
sensu intellecta fungus hiece specifice distinguitur statura 
constanter minore, carne compactiore, lamellis strietioribus 
magisque confertis, stipite nitidiore, glaberrimo, apice ob- 
solete furfuraceo, ita ut minime dubitemus, eam ceu speciem 
propriam proponere. Nolaneae clandestinae Fr. magis quam 
N. mammosae affinitate conjuncta.
