and capula (Jan.) ; Solenia ochracea (Feb). Amongst the Clavaria, I have found 

 fastigiata, and cristata in Dec, and flaccida in Jan. ; and amongst the Tremellini 

 I have found mesenterica in Mar., foliacea in Dec, and albida in Jan. and Apr., 

 Exidia glandulosa in Jan. and Mar., Ncematdia encephala in Mar., Dacrymyces 

 stillatus in Feb. 



Amongst the Gasteromycetes, the following I have found in the \vinter 

 months,— £atorr«a phalloides (Dec), Ocaster fimbriatus (Jan.), Bovista nigrescens 

 (Dec), Lycopevdon pyriforme (Feb.), Lycogala epidendrum (Apr.). 



To turn to the Ascomycetes, the morels seem only to be found in the spring. 

 Morchella esculenta (Mar., Apr., and May), semilibera (May), and Mitrula alba 

 (Apr.). In the winter, and early spring I have found Peziza venosa (Mar.), badia 

 (Feb.), vesiculosa (Apr.), micropus (Mar. ), humosa (Dec), coccinea (Dec ), mela- 

 stoma (Mar.), pygmaea (Mar.), stercorea (Feb. and May), virginea (Mar.), nivea 

 (Jan.), bicolor (Jan.), cinerea (Jan.), and Elaphomyces variegatus in Jan. 



I wish to mention, that I have excluded from my remarks any fungi which 

 I found only in November, so that those mentioned as seen in the vrinter months, 

 were growing when winter may fairly be considered as set in ; many others found 

 in the latter end of November might fairly have been included, but I thought it 

 best to draw a line at November. 



As an instance of the apparently capricious appearance of some fungi, in 

 seasons which seemingly were equally favourable, some morels grew in great 

 abundance one spring in Kingsweston Park (Gloucestershire,), on a spot where 

 generally a few may be seen. The following spring, which as regards the weather 

 was to all appearances equally, if not more favourable to their growth, being very 

 mild, not a specimen was to be seen. 



The common mushroom (Ag. campestris) is often very abundant one year, 

 and the next season, hardly any are to be found. How is this to be explained ? 

 Is it entirely owing to the season ? or is it caused by the temporary exhaustion of 

 the mycelium, owing to the abundant production of the previous year? The latter 

 cause is, I think, the most probable. 



From the season I will turn to the soil. Those most favourable, as far as 

 my experience has gone, are the light sandy loams, and shaley, and gravelly soils. 

 On these, fungi are usually more abundant, and better grown ; but on clay and 

 other heavy soils, I have never found them in such abundance, or such perfect 

 specimens. In a dry season, particularly, owing to the hardness of the ground, 

 they are often much distorted, from the resistance they meet with in breaking 

 through the surface ; and in a very wet season, these soils are chilled more rapidly, 

 and the fungi are unable to grow freely. The lighter soils being naturally freer of 

 drainage, are drier, and warmer, and thus more favourable to their growth. On a 

 heavy soil in Devonshire, Polyporoua perennis averaged 1 inch to IJ inches in 

 diameter ; but on a light soil in the same county, they grew larger, one I obtained 

 being 3J inches in diameter.
