Hola a todos. Subo unas fotos de un asco que hemo
I think it's a Hysterobrevium again (but not H. mori this time). The shape of the lirellae suggests Histeriales. On eboehm.com site I could see two possible species: H. smilacis and H. constrictum. The spores are more similar in shape to those of the latter, but the dimensions are closer to the former. On the other hand, the spores (of some) are surrounded by a gelatinous tissue, a characteristic that is also mentioned in the site for H. similacis. Can someone help?
The host is Cupressus lusitanica. The dimensions of the spores I got were:
(17.7) 18.9 - 23.3 (24.8) × (6.8) 7.2 - 9.1 (9.5) µm
Q = (2.3) 2.35 - 2.8 (3) ; N = 24
Me = 21 × 8.2 µm ; Qe = 2.6
Thanks in advance,
zaca
Hi Zaca,
Typical H. smilacis, I think. But you're right, it's not so far from H. constrictum. Eric Boehm wrote : "the illustrations depict a very thick wall and dictyospores highly symmetric in outline and septation". Septation is asymetrical in your collection.
Alain
Thanks for your opinion. Yes, the Septation is somewhat asymetrical.
I know that you collected it in several different hosts. DId it happen in Cupressus?
Best regards,
zaca
