Lasiosphaeris hirsuta ?

Eduard Osieck, 27-08-2019 18:18

This Lasiosphaeris collection has hyaline spores (53-66 um), when young with a short appendage (ca. 10 um). After release the cylindrical (upper) spore part becomes clearly inflated (7-9 um), but remains hyaline. The perithecia are strongly warted (tuberculate) and have scattered hairs. Ostiolar region with four or five ridges.

Is this collection within the normal range of variation of Lasiosphaeris hirsuta? The collection shows some features of Cercophora ambigua (as described bij Bell & Mahoney 2016) but the inflated spore parts do not colour brown.

Thanks for your help, Eduard

Re : Lasiosphaeris hirsuta ?

There is a wide variation in morphology of the ascomatal vestiture and ascospores of Lasiosphaeris hirsuta sensu lato. I'm always happy to sequence more collections from Europe if you want to send me your collection.

Cheers,
Andy

OK, thanks for your prompt reaction. I will send the collection in due time.
