 cystidia is not available. 



Mucidula al'phitophylla (Berk. & Curt.) Pat. [Agaricus 

 (Mycena) alphitophylla B. & C. : Agaricus (Mycetm) leucoconis 

 B. & C] appears to be very near, if not identical witli, the 

 present species. PatouiUard (Bull. Myc. Soc. France, XXV., 

 p. 9) states that it is " Entierement blanc pur, parfois fauve 

 plus ou moins bistre ou legerement rose. Chapeau lisse, non 

 ecailleux, convexe, visqueux ; lames larges, epaisses, distantes, 

 inegales, pulverulentes par une couche plus ou moins epaisse 

 de spores ; basides volumineuses, 60 X 15 /* ; spores globu- 

 leuses, lisses, 18-21 n de diametre, avec une grosse goutelette 

 brillante ; cystides fusiformes, 120-250 x 40-50 /i. Stipe 

 central ou excentrique, droit ou courbe, sans anneau, parfois 

 strie au sommet, glabre sauf a la base qui est villeuse et un peu 

 renflee."

Thwaites made two gatherings of this species, Nos. 100 and 

 397. He illustrated them by two figures , both on the same sheet. 

 The fungus grows in two forms, which occur together indiscri- 

 minately; in one form it is orbicular, and the stalk is more or 

 less excentric ; in the other it is circular, and the stalk is central ; 

 the latter form often grows in clusters from a swollen base. 

 Thwaites' figures give the first form only. Berkeley and 

 Broome divided them into two species, naming the central- 

 stalked, clustered form, Marasmius subaurantiacus , and the 

 excentric-stalked, orbicular or reniform examples, M. igno- 

 bilis. This species grows on small branches, M. aurantiacus 

 usually on the upper surface, and M. ignobilis curving up from 

 the under surface : the stalks of the latter, being in contact 

 with the soil, soon decay, and leave tlie pile us lying on the 

 ground near the stick or adhering to other pilei. Thwaites
