Physarum species having a crowded/aggregate sporocarps

Post by MaxRum » Wed Jun 07, 2017 5:45 pm

I am working on another clear Phyrasum sp. with limey single peridium, capillitium with rounded-oblong (knobby) limenodes, shortly stipitate (or subsessile) and black spore mass. The sporocarps are distinctly crowded or staphylous, that is groqing like small bunches, rarely merging. Sporocarps 0.3-0.6mm wide. Spores verricose without further ornamentations, bands or reticulae measuring 7.5-9.5(10um).

I have considered several Physarum species with these characters.

P. spectabile should have spores with bands and which I did not see. It also has larger spores (11-13um).[excluded]
P. licheniforme (P. lividum) offers a good match but i'm not appy for its larger spores 12-14um. [doubtful]
P. ovisporum should also have larger spores with a white band (lack of spore warts) which I did not observe [excluded]
P. sessile. is represented by solitary myxocarps abd smaller spores in the range of 6-9um [excluded]
P. cinereum is a close match with slightly larger spores (9-11um) but do not look to have an aggregated habit [doubtful]
but my favourity and best match is
P. daamsii which also has 9-11um spores (slightly larger) have that tightly packed / crowded sporocarps measuring 0.2-0.5um and bulky-rounded capillitium lime nodes

A very nice find. Your ID looks good to me.

Hurray! Thanks. Is this sp. recorded in UK?

I wouldn't be certain of ID without a proper look, but I can't see anything reason why it shouldn't be what you suggest.

As far as I know, it is not recorded in the UK.
