Re: Fungi on dung

Hi Chris, thanks for your ever-useful comments. Yes, I was aware of the move (back) to Lasiobolus but, as you say, FRDBI is behind the curve here . . . This is not an insignificant problem with many recent fungi name-changes, as the recording software and NBN are not up to speed, hence making record...

Re: Fungi on dung

With Chris Y's prompting, you should all have samples of herbivore dung starting to produce fungi. ;) One of the first Ascobolus species to appear is Ascobolus equinus . I have two on different substrates: one on the more usual deer dung and the other on an eagle pellet (either golden or white-taile...

Re: Chaenotheca trichialis?

I can not be any more definite with those pictures, happy to have a look at the specimen. As for algae, I suspect the LGBI2 was using a need to know basis; Stichococcus looks like nothing else associated with Chaenotheca species, so I have no idea if there are other algae that look similar, I hope ...

Hypoxylon fuscoides @ H. fuscum

In January I found the recently described Hypoxylon fuscoides ; this week I found the more frequent Hypoxylon fuscum . Indistinguishable in the field, the main differences are the spore-sizes and a KOH reaction in the former. I thought it might be useful to show a spore comparison for future referen...

Re: Growing on fallen twig of Picea sitchensis

An update: Brian Douglas suggests it could be Ionomidotis fulvotingens . This was the closest I got but was discouraged by the texts suggesting a broadleaf species. He goes on to say: "... I'd recommend vouchering it and keeping it safe, and keeping an eye out for more, in case anyone is doing a DNA...

Growing on fallen twig of Picea sitchensis

Apothecia dry and incurled when found; hydrated as images – possibly erumpent. Inamyloid in Melzer’s.
Spores 5.6-8.6 x 2.1-2.6 µm, smooth with two guttules.
Asci 35-41 x 5-5 µm
Paraphyses filiform with some branching.
I’ve failed to key this out and would welcome any suggestions.

Re: Hyphomycete

Thanks for looking, Paul. I wasn't too optomistic as I know how difficult they can be. As we were in the teeth of another gale I grabbed something from the greenhouse. :)
Cheers, Chris

Sistotrema sp.

Growing internally on rotting Sitka spruce (Picea sitchensis).
Spores inamyloid: 5.6-7.0 x 3.7-4.6 µm.
Basidia predominantly 6-spored: 20-23 x 7.3-7.7 µm.
Hyphae with clamps: 3.3-4.3 diameter.

It's the spore size and shape that I can't fit to species.
Any help welcome.

Regards, Chris

Hyphomycete

Growing on the dead stems and leaves of Triteleia laxa.
Conidia smooth, 0-3–septate, 8.8-14.7 x 4.6-5.9 µm.
Possibly one of the numerous Cladospora species, but I am unable to key it out so any help welcome.

You might want to check out Pycnoporus coccineus, Southern cinnabar polypore.

Re: Fungi on dung

I have only found this once, on pony dung, but it's probably not scarce. I endorse Chris's comments especially regarding willing helpers.
