Monthly Mushroom: Wrinkled Peach (Rhodotus palmatus)

Monthly Mushroom: Wrinkled Peach (Rhodotus palmatus)

by Jasper ~ 17 September, 2018 ~ one comment

One can understand why amateur mycology might seem like an unrewarding and slightly odd pastime to the outside observer. There are many who might consider squatting amongst the leaf litter with guidebook in hand, trying to pinpoint whether the flush of slimy brown-yellow toadstools sprouting from a rotting log or tree stump could be Hypholoma fasciculare, Hypholoma capnoides or maybe even Kuehneromyces mutabilis, an ultimately pointless endeavour. Few would deem being able to distinguish Dead Moll’s Fingers from Dead Man’s Fingers or a Leopard Earthball from a Common Earthball  among the most vital of life skills.  Read more...

A different perspective on the honey bee – Apis mellifera.

by Chris ~ 14 September, 2018 ~ 2 comments

This month a paper appeared in the Science Mag authored by people at the Cambridge Conservation Group; it argues that the present focus on the (western) honey bee (Apis mellifera) is misguided.

The honey bee is indeed the most important single species for crop pollination, and there has been a rapid growth in the number of managed colonies over the last 50 years.  This is especially true in areas where this honey bee species has been introduced.  It was introduced to the Americas in the 1600’s.   Read more...

Owls and Boxes - Part 2

Owls and Boxes – Part 2

by Chris Saunders ~ 5 September, 2018 ~ comments welcome

It was disappointing not to have a resident owl in the newly installed nest box, but at least we had enjoyed the trail camera shots of an owl exploring a potential site.   In mid-March we blocked the hole, having expelled a squirrel family on several occasions. By this time of the year tawny owls will have chosen their nest site, and be well into their courtship cycle. Perhaps something will persuade them to use the nest box next year. Read more...

Bumblebees ‘hooked’ on neonicotinoids?

by Chris ~ 1 September, 2018 ~ comments welcome

Researchers at Imperial College, London (Dr Andres Arce, Dr. Richard Gill et al) have been conducting field trials on the foraging behaviour of bumblebees and the effect of neonicotinoids.  As wild bees have a choice on where they feed, the researchers wanted to know if the bees could detect insecticides and learn to avoid them.

Threatened spiders

Threatened spiders

by Chris ~ 31 August, 2018 ~ comments welcome

According to the British Arachnological Society, there are some 654 different species of spider in the U.K.   However, a recent survey (link opens a PDF) they undertook (in conjunction with Natural Resources Wales) suggests that 16% of our spider species are threatened.   Eighteen of these species are critically endangered and eighty four species are classified as vulnerable or endangered. The terms used are based on those of IUCN Red List categories, so critically endangered means Extremely high risk of extinction in the wild. Read more...

Bumblebee update - brief notes

Bumblebee update – brief notes

by Chris ~ 28 August, 2018 ~ comments welcome

The yellow banded bumblebee (Bombus terricola) is a North American species of bumblebee.  It has been in decline across its range.  This bumblebee is now down to about 10% of its former numbers.   Recently, its genome has been sequenced at York University, Canada.  This genetic analysis shows that the bumblebees are inbreeding.  As bees become more inbred, the face difficulties in maintaining their population numbers.  As population become smaller, there is a greater risk of inbreeding.  Inbred bees have problems in terms of fertility.  Males can become infertile so that if they mate with a queen, there are no offspring or the queen may produce sterile males instead of worker bees.

Unusual or exotic trees - the horseradish tree

Unusual or exotic trees – the horseradish tree

by Chris ~ 22 August, 2018 ~ comments welcome

The horseradish tree has other names - moringa, the drumstick tree or the benzoil tree.  It scientific name is Moringa oleifera.  The word moringa is derived from a Tamil word, murungai - which means twisted pod, referring to the shape of the tree’s young fruit. 

It is native to the foothills of the Himalayas.  It is known to have been cultivated for some 3000 years (source : Mabberley’s Plant Book) and it is a very ‘versatile’ plant as nearly every part of the tree can be used.   It can thrive in semi-arid conditions. Moringa is grown in India, Thailand, the Philippines, parts of the Caribbean and Indonesia. Read more...

Monthly Mushroom: The Parasol Mushroom (Macrolepiota procera)

Monthly Mushroom: The Parasol Mushroom (Macrolepiota procera)

by Jasper ~ 17 August, 2018 ~ comments welcome

Parasols should be popping up all across the UK at the moment. Paul Stamets in Mycelium Running calls them “one of the most majestic of all edible mushrooms.” The second part of the Latin name Macrolepiota procera literally means lofty, upraised or extended to a great height, and they are certainly hard to miss on late-Summer and Autumn forays. 

The Parasol mushroom starts out looking something like a drumstick, before the initially egg-shaped cap opens up to a maximum size of around a foot across (typically between 10-30cm) when fully grown. Read more...
