Leucocoprinus birnbaumii - Plantpot Dapperling

Leucocoprinus birnbaumii - Plantpot Dapperling

I recently received an email from a volunteer at the Royal Botanic Garden Edinburgh who required some help with fungi identifications.  He also sent me a photograph of a fungus found in a Research Glasshouse that was growing in a plant pot next to an Amorphophallus paeoniifolius.  

Plantpot Dapperling or Flowerpot Parasol is a tropical fungus that can be found in heated glasshouses or greenhouses all year round.  It is uncommon and its characteristics are:

Cap up to 5 cm across, firstly ovate then bell-shaped and at maturity flat with an umbo.  Its colour can vary from bright yellow to greenish yellow/pale yellow and when dry more brown.  The texture is dry/mealy/minutely scaly.  In some mature examples the margin edge can be striate.

The gills are free, yellow and crowded.  The stem is slender but can have a slightly bulbous base.  A small ring may be seen high up on the stem and also there may be remnants of veil.  Although the ring can  disappear.  It should not be eaten.

With kind regards and thanks to Robert Jones and the Royal Botanic Garden Edinburgh for allowing me to use this photograph.

Coprinus niveus - Snowy Inkcap

Coprinus niveus - Snowy Inkcap

This fungus grows specifically in dung - usually horse or cow.  The example I found was solitary in horse dung in a grass verge.  As the name suggests this fungus is white, and the cap is covered in chalk-white meal.  In fact, it looks as though it has been coated in fine, dry, white snow.  A rather captivating mushroom actually.  Very visible when appearing out of dark coloured dung.  I was fortunate to capture this one in its prime.

Characteristics:

Cap up to 3 cm high.  Egg-shaped to conical firstly and then bell-shaped at maturity. White and covered with chalky white meal. Also with maturity the margin edge splits and can roll back.  The gills are firstly white, quickly turning grey, then black and deliquescing.  The stem is rather tall up to 9 cm with a cottony base and scurfy texture.
It tapers slightly from bottom to top. It has no strong odour.   Usually in small groups on horse or cow dung.  Summer to Autumn.  Quite frequent.  Not edible.

Melanoleuca verrucipes - Warty Cavalier

Melanoleuca verrucipes - Warty Cavalier

On a lovely May morning walk to a local large park namely Wollaton Hall, Nottinghamshire, I was wandering through very long grass and came across a small cluster (approx 10-15) whitish fungi.  I took a series of photographs and a sample.  The stem struck me as being very distinctive - blackish and spattered with dark scales, and the smell being a mix of almonds and faint aniseed - fruity indeed.


I could not find this fungus in any of my books.  I duly sent the sample off to Howard associated with Notts Fungi Group for a positive identification via spore print analysis.

I could not find this fungus in my books because it is in fact rather rare.  It is called
Melanoleuca verrucipes - Warty Cavalier and belongs to the Tricholomataceae group.  This fungus was first discovered in the UK in 2000 in Highgate Woods, North London, according to the FRDBI records held by the British Mycological Society (BMS). There are 47 records to-date, the last being in 2015.  My record will be recorded by Howard where appropriate.

Below is a series of photographs which show in detail this fungus, and also at the end of this post is a description of my observations.

Observations and characteristics:

Found in long grass with mixed trees including Lime and Beech, bark chippings present.  In a small cluster up to 10-15. Cap white, slightly striate margin, up to 8-10 cm diam.  Depressed centre with ochre spot.   Gills crowded and close and the same colour as the cap.  Stem up to 8 cm white with very distinctive dark brown to black scales.  Base slightly bulbous and wooly at base.

With grateful thanks to Howard Williams for confirming the identity of this mushroom via spore print analysis and for providing the photograph of such.

Morchella esculenta vulgaris

Morchella esculenta vulgaris

I always enjoy the visits to my allotment and a walk round the perimeter to see if I can find any new fungi.  I nearly missed it, but growing in soil, solitary next to a raised bed was a Morchella esculenta vulgaris.  At various times its also had the following names:
Morchella conica, M. deliciosa or M. esculenta var. vulgaris.

It is quite distinctive in that the ribs of the cap are more or less parallel and the pits have grey coloration. 

Characteristics: 5-12 cm high, the cap is ovoid. The ridges (ribs) being mainly parallel, the pits are irregular in shape and with grey coloration and having a honeycomb appearance.
The cap being grey-brown but becoming lighter with age. Stem is white and hollow and tapers slightly.  Slight grooves can sometimes be seen. No distinctive odour or taste.
To be found in gardens and wasteland - late spring.  Occasional.

Geopora sumneriana - Cedar Cup

Geopora sumneriana - Cedar Cup

As the common name suggests this fungus is most likely to be found under or near Cedar trees, although it can appear sometimes near Yew trees, suggesting that formerly Cedar trees might have been nearby.  It is to be seen from late Winter to late Spring. It develops as an underground sphere and then slowly becomes visible as it pushes through the soil. 

Below is an image of a young sphere just becoming visible as it emerges in the soil.


Young sphere

This fungus can easily be overlooked as it tends to blend in with the soil.  It is also a challenge to photograph.

Cedar Cup is uncommon.  It has patchy distribution, tending to be found in the south of the UK, in fact south of the Severn to the Humber.

Below is a sequence of images showing the Cedar Cup is varying stages of development and showing its characteristics.

Showing interior and hairy texture


Characteristics: Cup up to 7-8 cm across.  Firstly a sphere lying just below the soil.
It breaks through in small groups, sometimes very close together and even over-lapping.  At maturity it splits into several rays.  The exterior is light to medium brown and is covered in dark hairs.  The interior is smooth and pale buff or cream.  Not edible and is uncommon with patchy distribution mostly in the south of the UK. To be found with Cedars.

With grateful thanks to JP for allowing me to photograph this fungus in her garden and also to Howard Williams for undertaking the spore print analysis, adding the details to the CATE National Database, and sending me the three images below showing details of the spores.

A very good result as this is, I believe,  a first recording for South west of Nottingham.

Clavulina Rugosa - Wrinkled Coral Fungus

Clavulina Rugosa - Wrinkled Coral Fungus

Strolling around the University Park, Nottingham University I was pleased to come across Wrinkled Coral Fungus again.  Although this fungus is common this is only my second sighting.  This time I was able to photograph it just emerging through the soil, and also found a young example.  For those out there looking for it - I must say that when in the 'just emerging stage' it is very easy to overlook.  It lies flat to the ground and looks like cauliflower florets.

Showing the wrinkled texture




Mature fungus


On close inspection it is easy to see how it acquired its common name as the wrinkles are so apparent.

Characteristics:

White or cream the fruit body is 5-10 cm tall and wrinkled in appearance.  It is branched towards the tip, then blunt.  The texture is soft and flexible and its fragility can cause bits to break off.  There is no obvious stem.  To be found in small groups on soil and mossy grass in or near leaf litter next to trees.  Summer to Autumn.  Common.
