Simocybe sumptuosa 100 Acre Wood nr Worksop Notts
An uncommon fungus, dark brown ageing to tawny, widespread but mainly southern. These were growing on a large fallen beech log, a favourite substrate, none exceeding 3.5cms in diameter. Characterized by the substrate, felty dry caps, red brown gills, curving stems often with bulb at base and, microscopically, by slightly reniform spores and many capitate wavy cystidia.
1st Notts record.
Phanerochaete sanguinea Carlton Wood, Carlton-in-Lindrick 3-8-2019
A rare white crust fungus which bruises a rosy red before becoming dull pinkish-orange when older. Its cystidia are thin and incrusted often with smooth pointed tips. About 45 records nationwide. It appears to grow mainly on hardwoods but also on conifer wood. This specimen was on the underside of rotten fallen oak. I also found it in 2017 on the underside of a fallen oak branch at Daneshill Lakes. Before then it had not been recorded in Notts since the 1800s in Sherwood Forest.
Venturia populina Carlton-in-Lindrick Notts 16-7-2019
This blackened upper surface of a leaf of White Poplar growing by the village pond here is a sign of attack by Venturia populina which can affect various trees in the Poplar family. Ascospores can be formed but this is the conidial state. Conidia when immature have no septa, but as they mature they may become 1- or 2-septate. CATE2 has only 7 records, but the species is likely to be under-recorded rather than rare.
Interestingly the white underside of the same leaf has another fungus, this time an orange-yellow rust, growing on it: Melampsora populnea. Unlike the Venturia this is certainly very common on poplar leaf undersides. There is already a photo of this rust from this location on our website. For those interested it can be found in the Photo Gallery G - N section.
