like an iridescent button on the gelatinous envelope through which it has 
emerged ; and in the last stage, when the walls have burst and the dark 
grey spores are exposed. 
Comatricha nigra (Pers.) Schroeter. Two specimens were found, 
one typical with long slender stalks ; the other with short stout stalks 
and weathered mouldy capillitium; possibly this should not be referred to 
C. nigra , but is an irregular growth of Enerthenema papillalum (Pers.) Rost. 
Trichia varia Pers. Fairly abundant in both mature and young stages. 
T. contorta (Ditm.) Rost var. inconspicua. Found at the junction of 
torn bark and wood on an old hornbeam log. 
T. Botrytis Pers. Several gatherings on dead wood. 
Arcyria denudata (L.) Sheldon. Young white immature sporangia 
and the remains of a few old red ones were found.

LIST OF MICROFUNGI COLLECTED ON 16th OCTOBER. 
1 
I have to thank members for handing over to me certain of the species, 
and Miss Lorrain Smith, who has collaborated in the description of the 
interesting new species Lasiobolus tiligotrichus . The following were 
gathered :— 
Pilobolus crystallinus Tode. 
Piptocephalis repens de Bary. 
Ascophanus microsporus Phill. 
Lasiobolus oligotrichus A. L. Smith et Ramsbottom, Sp. nova. As- 
cophores gregarious, sessile, conical, smooth, orange, at first closed, then 
opening irregularly, with irregular external cells, 100— 2icm wide and 
280—300^ high, provided with hairs on the exterior, which are sometimes 
very few in number, simple, non-septate, straight, acute, hyaline, about 
85—95 m X5ju ; asci few, subcylindrical, rounded above, almost sessile, 
90—14CMX18—3CM, not turning blue with iodine: paraphyses slender, 
numerous, reaching 15CMX2.5M, vacuolate, hyaline, very rarely septate 
or branched, not dilated at the apex : spores ellipsoid, about 20 X I2 M . 
On rabbit pellets, Fair Mead, Epping Forest. Somewhat similar to 
L. equinus, but differing in the shape and size of most of its parts, and 
especially in the colourless, generally unbranched, paraphyses. The 
asci vary in number from two in the smaller forms up to about ten. The 
hairs may be entirely absent or may vary in number from one to several.
