During a general survey for the current Danish basidiomycote atlas a rather unpromising locality in Northern Jutland produced a series of rather interesting records including the subject of this blog.
Under a smallish apple tree (Malus domestica) lots of this years fruits showed signs of Molinia (fructigena) infections and a closer inspection of the soil in the shade of the crown produced many sclerotized apples covered in big, stipitate apothecia, some of which displayed a rather peculiar dark grey brown color.
Under the microscope the colour was shown to be caused by (over-) mature ascospores that made the preparation superficially resemble one of a Hypoxylon species! [sp. ca. 10. x 4.8 µm with some of the pigmented ones clearly bigger; one side flattened and one end slightly more pointy than the other - very close to a Hypoxylon spore without a visible germination apparatus].
The spores match otherwise M. fructigena but at present we cannot exclude M. laxa and M. fructicola. We have so far been unable to locate information on the darkening of the ascospores. The apothecia are ± hairy, even at the apothecial margin, up to 5 mm wide and 10 mm high including the stipe.
[UPDATE: as seen in the comments below, this may not be a Monilinia at all but rather a Lambertella (and if so, the first finding of this genus in Denmark)]

From Caroline Hobart we have this announcement of a translation of Stangls book on Inocybe:
It's a translation in English, bigger than the original and thicker with some up to date comments about status of different sp and their occurrence in UK. Index clear and helpful. I have just had my copy and its excellent ....I'm hopeless at German....
Please send a cheque made out to Archie McAdam for £20 + p&p

Many mycological colleagues and friends from the Netherlands and Belgium.
attended the farewell lecture and party, where he among other things was presented a full set of water soluble oil paints.
Machiel Noordeloos, Strophariaceae s.l. in Fungi Europei vol. 13. 648 pp, 43 plates with line-drawings, and 377 colored photographs. Edizioni Candusso, 2011. Price Euro 69.--
This monograph combines up to date knowledge of the species with a modern classification, based on morphology and recent molecular/phylogenetic studies.
The book contains keys, descriptions and line drawings of about 100 species, distributed over 12 genera: Stropharia, Leratiomyces, Hemistropharia, Hypholoma, Deconica, Psilocybe, Pholiota, Flammula, Hemipholiota, Kuehneromyces, Meottomyces, and Phaeonematoloma. In additions most species have been depicted in colour, often with several photographs, in order to show variability. Micrographs of spores and cystidia are also given.
The book can be obtained from the publisher: www.edizionicandusso.it, booksellers and the author.

During our workshop in Thimphu, Bhutan this month we have encountered what would appear to to match Campanophyllum proboscideum, a fungus known from Mexico south to Ecuador (and further down?). It it attached by a peculiar snout-like dorsal extension - hence the epithet. It was found on 4 big logs in a wet montane forest in upper Thimphu Valley (Dodena) and was photographed by Morten Christensen.

There is active fungal research in Iceland.
Mycologists might know that there was published a comprehensive book on Icelandic fungi by Helgi Hallgrímsson in 2010: Sveppabókin – Íslenskir sveppir og sveppafræði (website in Icelandic, but google translator is not so bad, just enter the address of the website.).
And somehow there must be more than desert-like vegetation and crazy volcanoes - a checklist (Helgi Hallgrímsson & Guðríður Gyða Eyjólfsdóttiris) is available on the internet comprising 1.531 species of "microfungi". Also nice photo galleries can be found on the web: cap fungi and others.
We even have a blog fellow in Iceland: gamlisveppur.bloggar.is.
So this is an interesting country for people interested in fungi. - And I would like to keep you up to date with Icelandic mycology and fungal experiences.

In the microscope it has aseptate spores which are a little to large, so, not C. viscosa sensu stricto (miss good Calocera literature).
By the way the orchids are small but numerous at 3000 m height (click the pictures to enlarge):

We have a class of six local students which are very interested in fungi (always a pleasure). Here Thomas Læssøe is giving an introduction to collecting with Mikako Sasa watching:
