Salmon Pulvinula
Zuzana Sochorová (Egertová), 20-07-2014 13:43
Zuzana Sochorová (Egertová)Bonjour,
this Pulvinula is from Georgia - Batumi botanical garden, Transcaucasian section. It grew in a flowerbed on a wet ground with pieces of wood, together with Peziza michelii. Collected on 6th July 2014.
Apothecia 0,5-4,5 mm broad, sessile, pink-salmon, sometimes with yellow tinge, rounded or irregularly shaped, flat or slightly convex.
Spores globose, 10,5-13 micrometers, smooth, hyaline.
Asci cylindric, 195-220 x 9,5-13,5 micrometers, with 8 spores, no reaction in Lugol.
Paraphyses about 1,5 micrometer broad, curved, with orange granules.
Pulvinula laeterubra seems to be the most similar species, but asci of my Pulvinula are longer then given by Pfister - (140)-161-184-(200) micrometers.

Re : Salmon Pulvinula
Paraphyses divisées au sommet pour P. laeterubra... sinon, regarder du côté de  Pulvina globifera...

Re : Salmon Pulvinula
Merci Gilbert.
I have got one more Pulvinula from Georgia (from a different part of the country - Racha mountains) and it´s true it´s very similar to Pulvinula from Batumi microscopically, although totally different macroscopically.
These were white, up to 1 mm broad and grew together with Rhodoscypha ovilla. Unfortunatelly I didn´t find free spores, the biggest spores inside the asci measure 11-13 micrometers and have  got 1 big guttule. Asci are 188-212 x 10,5-13 micrometers, contain 8 spores. Paraphyses are 1,2-1,5 micrometers broad, curved, not branched at apex. 8 spores in asci exclude P. lacteoalba, apothecia are too small for P. albida, spore size is too small for P. alba, asci are too short for P. niveoalba (and its spores should contain many small guttules)... so I think Pulvinula from Racha mountains should be P. globifera. Then you are probably right with globifera from Batumi... thank you.

Re : Salmon Pulvinula
Chère Zuzana,

Pfister (1976) - Synopsis of the genus Pulvilula, in Occasional papers of the Farlow Herbarium 9, indique que P. lacteoalba J. Moravec et probablement une forme tetrasporique de P. globifera (Berk & Curt.) Le Gal.

Amicalement

Re : Salmon Pulvinula
Merci René. I read this comment in the Pfister´s article at Cyberliber, but there is P. lacteoalba in your key (which is much newer then Pfister´s work), so I didn´t know what is the recent view on this.
However, I´m unsure about the identity of my fungus again, because Marcel wrote me Pulvinula globifera was considered to be a tropical species. I didn´t know this fact because this species was included in Pilze der Schweiz.
On the other side, the locality of the salmon Pulvinula is a botanical garden and I think strange fungi can grow there...
