Summer early lock-down local walks still finding rare or uncommon fungi - Part 1

Continuing on from my last report I was able to venture out under the legal requirements of coping with Covid-19 and even better, as being on my own and in wilder places allowed even more interesting fungi to be found. I won't elaborate to much as I normally drone on perhaps too much how I came across species, so I'll just get on with the reporting. 

Breney Common - on Bamboo. On a single dead cane presented interesting species on the same substrate which turned out to be very unusual rare species for the UK as well as Cornwall. With the help of AscoFrance colleagues these were Apiospora montagnei in arthrinium state plus Arthrinium arundinus
Bodmin Nursery - on very old central Salix babylonica var. pekinensis (uncommon-not for sale!) - or Corkscrew Willow - Drepanopeziza sphaerioides - 6th UK/1st Cornwall.
Ladock NR: On Rosebay Willowherb - Pezizella punctoidea - 1st SW England. "Er Dad what's that man doing in those weeds - Move on son!"
Treraven Woods: Favourite local patch came across under Ash as a squashed toffee-like ascomycete of which I had no idea what this could be. After a great deal of checking and with the help of my colleagues in France, they led me to a new Hypoxlon for SW England in H. cercidicola. After thinking this was a first for the UK I found out that the European specify the species is ending with ...dicolum. Pulse returned to normal when finding out from Paul Cannon (Kew) the real identity and taxonomy spelling. 
During my first visit to the delightful Tredinnick Pits at the NE end of Redmoor NR, I located quite a few ascos the best being Pseudovalsa lanciformis
A quick trip to the zoo also produced some interesting species (Exmoor Zoo) with an common Inocybe appearing just before the Beast of Bodmin cage. This came out as Inocybe hirtella var. hirtella. Moving onto another new location but still close to me was the trail at Little Petherick village NW trail. I only need the first 200 metres to find among the many Wild Angelica the rare rust fungi Puccinia angelicae - probably 1st for Cornwall. Getting towards the end of the month and really abiding by the lock-down I took my wife to Tesco's, as you do. While waiting in the car (I did the shopping for two mths before this!!) I strode out across the car park and after careful checking found an Eutypa species, again with expert help, the nearest I could get to was probably E. leprosa. Great find and 3rd in Cornwall. 
Lastly, on this Part 1 report of the summer mths. I visited Pentewan Beach for the first time and some interesting ascos were located. Not rare but, very often neglected as so small, minute hairs on stems of old herbaceous plants Periconia byssoides was discovered. They are very common but almost invisible! Part 2 follows.
