Fungi in the botanical garden


Agaricus augustus

The weather had been dry.

Just a few days ago, some rain had started, but not enough for more fungi than usually to show in the botanical garden.

Still, there were quite some interesting species today.

Under a tree, big specimens of The Prince, Agaricus augustus; called after the first Roman emperor.

Close to them, much smaller mushrooms: a Tubaria species.

The species in this genus are hard to tell from each other.

In the systemic part of the botanical garden, Conocybe digatilina.

And smoky bracket.

And Helvella crispa.

And Boletus chrysenteron.

And Scleroderma areolatum.

In the grass: Laccaria laccata.

On a tree trunk: soft slipper mushroom.

Hans Adema told about a rare mushroom, Amanita inopinata.

It grows not here, but only in Cronesteyn elsewhere in the city, Alphen, and New Zealand.

Fungi, growing from spores, can expand over long distances.

During the First World War, spores in clothes of New Zealand soldiers brought the octopus stinkhorn to Europe.

Growing between the ferns: conical brittlestem.

On a branch: jelly-ear.

Here, growing on common ash; not on elderberry, as it often does.

Growing on trees: Xylaria longipes and Xylaria polymorpha.

And Xylaria oxyacanthae.

On the ground: Lepiota aspera.

On a big tree where owls nest: southern bracket.

Before we left the garden, we noted two crocus species flowering, not in spring as other species do, but now: Crocus cancellatus; and saffron.

Autumn flowering American plants: here.

  1. Like most members of Scleroderma, S. areolatum resembles but is only distantly related to the giant puffball. It can be distinguished from the giant puffball by cutting it in half; the puffball will have a solid, denser middle, with no signs of a developing cap mushroom. They are usually 1–5 cm in diameter, and grow individually or in small groups. They are commonly found in deciduous forests, in neutral soil. They are poisonous, and ingestion can lead to vomiting, diarrhea, and in larger quantities, fainting.
