Hi everyone,
I found this lirellate fungus on the roots of a Juniperus shrub. Some of its micro features are:
Asci: cylindrical with up to 110 µm in lenght and ~12 µm in width;
Spores:
- hyaline at first, soon pale brown and later brown;
- 3 to 6 transversal septa and 1 longitudinal septa in one or several middle cells;
- dimensions:
(14) 20 - 23.7 (27.5) × (6.1) 6.3 - 7.4 (7.6) µm
Q = (1.9) 2.9 - 3.5 (3.7) ; N = 31
Me = 22 × 6.8 µm ; Qe = 3.2
Initially I thought that it could be Hysterium, but the spores are more tranversely septate and, moreover, also have a longitudinal septum.
Looking to the information avalable at
http://www.eboehm.com/hysteriaceae.html
I realise that most probably it is a Hysterobrevium sp.. There are only three species mentioned in this genus: H. constrictum, H. mori and H. smilacis, the first and the third with hyaline spores at maturity, leaving Hysterobrevium mori as the possible candidate for the classification. Is it so or are there other choices?
(at the "Key to the species of Hysterographium, Hysterobrevium and Gloniopsis" two other genera are considered but with different features, as far as I can understand. Recently I found a species of Hysterographium but never found one of Gloniopsis.)
I would like to have comments or remarks about this uncommon (for me) find. I attach a set of photos.
Thanks in advance,
