FUNGI NEW TO BRITAIN. 
By Annie Lorrain Smith, 
A podachlya Pringsh. 
Hyphae with cellulin grains, constricted at intervals, branched, 
the branches rising immediately below the constriction ; 
sporangia terminal, pyriform or globose, few-spored ; zoospores 
on escaping become surrounded by a thin pellicle and remain for 
a time at the mouth of the sporangium, swarming later with two 
lateral cilia and leaving a hollow sphere of empty cells; sexual 
organs unknown ; conidia terminal, globose. 
A. pyrifera Zopf. 
Mycelium long; sporangia pyriform, sometimes ovate or 
fusiform with a small beak, a fertile branch often rising beneath 
the emptied sporangium, the repeated branching forming a 
sympodium; spores bean-shaped; conidia globose, with a 
smooth cuticularized outer wall. Found by Dr. Maurice Gepp 
on a hazel stick floating in running water near Shrewsbury.

Achlya racemosa Hildeb. 
Hyphe large up to 80 yp thick; sporangia cylindrical-clavate, 
large, varying in size from 100-640 mw in length by 604-21 mu 
in width ; oogonia terminal on short stout branches, produced in 
great numbers along the main hyphae, globose, 50-57 pe in 
diameter with a thick brownish or yellowish membrane with few 
oospheres ;_ antheridia always present one or two to each 
oogonium, obconical, on slender branches which rise from the 
stalk ofthe oogonium : oospores few 1-6, rarely up to 12, globose, 
thick walled, smooth, 20- 30 mw in diameter. 
Var. stedd 7gera Cornu, similar to the above but the oogonium 
beset with wart-like outgrowths.
