Fabulous Fungi at Holy Trinity Prestwood
This churchyard may not look much different from any other at first glance, but taking a closer look, especially in autumn, can reveal many colourful miniature wonders.
The grounds at Holy Trinity represent the original acid grass heath that was once established throughout the Chilterns' commons, and almost entirely
destroyed during the 19th century. The churchyard combination of no fertilisers, regular mowing and removal of cuttings has created the ideal conditions for what is known as a "waxcap grassland" where rare fungi can flourish. This type of habitat is a national priority for conservation and it takes a very long time to develop.
Fungi play key role in the environment. They decompose dead vegetation and their subterranean links provide plants access to essential nutrients. Fungi also have a magic in their unpredictable and mysterious ways, and in the variety of colours and forms they exhibit.

Wonderful Waxcaps
Waxcaps are fungi often characterised by their colourful and waxy or slippery-looking caps. They are only found in ancient unfertilised mossy grassland, amongst other weird and interesting fungi.
This churchyard has 23 different waxcaps, qualifying it as a site of international importance. Some species have survived here that are no longer known anywhere else in the region.

Middle Column (Illustrations)
a) Parrot Waxcap (Hygrocybe psittacina)
The colour varies from yellow to vivid green, with unique deep green
stems. You can see waxcaps from September to December.
b) Meadow Waxcap (Cuphophyllus pratensis)
One of the largest waxcap fungi, it appears from late August until
December.
c) Scarlet Waxcap (Hygrocybe coccinea)
Appearing from late October to November, the bright red colour of the
cap fades with age.
d) Butter Waxcap (Hygrocybe ceracea)
The name comes from the bright colour and greasy feeling of the cap. It
can be seen in late summer and autumn.
e) Indigo Pinkgill (Entolama chalybeum)
The gills are white at first becoming dirty salmon pink as it ages. It can
be seen in summer and autumn.
f) Pink Waxcap (Hygrocybe calyptriformis)
Also known as the Ballerina Waxcap, its flared radially-split caps give
the appearance of a ballet dancer's tutu.
g) Slim Coral (Ramariopsis subtilis)
An uncommon pale branched coral fungus, occasionally found in lawns and
unimproved grassland.
