Saccobolus eleutherosporus

Bonjour tous


This rarely-reported Saccobolus has turned up in England - first found by Nick Aplin in October 2017 in East Sussex. I have recently collected it in West Yorkshire, 300 kilometres to the NW.

As can be seen from the composite image the spores have scattered ornamentation, pale for Saccobolus. In the first collection the spores barely became "free" - an important character in S. eleutherosporus. So a week ago I collected more from the same site (last four images). In what is clearly the same fungus the spores had paler pigmentation than the previous collection and showed all stages from spores "in formation" to totally dissociated ones (the latter very obvious when discharged from the ascus). Indeed it seemed as though the heavier and darker the pigmentation the stronger the attachment of the spore-cluster. In all apothecia I examined there was yellow pigmentation in the paraphyses and often in the ectal excipulum - see image.


I do not think that either Nicolas' or Enrique's collections are S. eleutherosporus. I am puzzled by the apparent rarity of this fungus - there seem to be fewer than 10 authentic collections. Perhaps other AF members know of more than the ones already mentioned (something like 2 each from France, Belgium, Austria & UK).

Cordialement

Chris

Re : Saccobolus eleutherosporus
Good evening Chris.

The presence of what appears to be yellow pigment effectively raises a question; but perhaps it is a question of parasites external to the fungus. On the other hand, I have already found certain species of Saccobolus, such as Saccobolus depauperatus, with the presence of pigment in places. The age of apothecia at may also be of importance. Is this pigment present on all copies?

I think it is still despite everything Saccobolus eleutherosporus, which is not a very common fungus and often difficult to identify with certainty.

Amitiés.

Michel.

Hello,

here is a link to a discussion in a forum, but unfortunately only in German.

Peter.

Re : Saccobolus eleutherosporus
Thank for the link Peter

I have no doubt that the collection is the same species as mine and Nick's. I may have missed it, where was the collection made? Presumably Germany, or perhaps Austria? In answer to Michel's question, there was almost always some yellow present, giving the apothecia that "sparkling wine" colour mentioned in the Pilzforum post.

I shall now think of myself as a Dungpilzfreund ;-) . . .
