Pestalotiopis funerea
William de Jong, 14-02-2022 14:00
Hi everyone,

Two weeks ago I found a Pestalotiopsis species on dead, still attached, leaves of Thuja (in the Netherlands).
Conidia with 5 cells; outer cells hyaline, three median cells brown. basal appendage 3,7-8,8µm  (n=4); 4 to 5 apical appendices (longest varying from 8,2 to 14,4 µm; n=8). Conidia without appendages: (24,6-)25,1-29,2(-29,9)x(7,9-)8,3-9,1(-9,6) µm; avg 27,2 x 8,7 µm; Q=3,12 (n=16). See also the attached pictures.
Host + details match the description of P. funerea in Steyaert (1949), Contribution à l'étude monographique de Pestalotia de Not. et Monochaetia Sacc. (Truncatella gen. nov. et Pestalotiopsis gen. nov.). 
Is this indeed P. funerea?

Best regards, William de Jong

Re : Pestalotiopis funerea
Dag Willem,

Ik denk dat je juist gedetermineerd hebt.
De apikale aanhangsels van deze soort kunnen evenwel tot 30 µm lang zijn. Indien deze apikale aanhangsels nooit langer dan 15 µm zijn komt P. hispanica ook in aanmerking.
Het genus Pestalotiopsis is niet erg substraat-specifiek, maar deze soort is het wel (op blad van coniferen).

Re : Pestalotiopis funerea
Dag Bernard,

Bedankt voor je reactie.
Ik heb even door de mic-foto's gebladerd en kom ook sporen tegen met apicale aanhangsels langer dan 20 µm (zie foto), dus dan valt P. hispanica af. Ik zal eens kijken of ik nog wat meer foto's kan maken daarvan.

Is er ook recentere literatuur van P. funerea? In Nag Raj 1993; Maharachchikumbura et al., Studies in Mycology 79: 121–186 (2014); en Liu et al., Studies in Mycology 92: 287–415 (2019) wordt deze soort namelijk niet genoemd.

Groeten, William

Re : Pestalotiopis funerea
Hi William
Did you consider also P. thujicola (described as Pestalotia by Maas 1971, Mycologia 63: 667)?

Re : Pestalotiopis funerea
Hi Eduard,

Thanks for your reply.
I couldn't find much about P. thujicola. And on the Verspreidingsatlas Bernard states in the feedback section that P. thujicola is a synonym of P. funerea: https://www.verspreidingsatlas.nl/1356010#
Maybe Bernard could go into this?

Thanks for the reference of Maas 1971, Mycologia 63. I'll have a look at it.

Groet! William

Re : Pestalotiopis funerea
Thanx, I wasn’t aware of that feedback. It would be useful to know the reference for that conclusion.

Re : Pestalotiopis funerea
Hi William and Eduard,

Indeed, I think that, based on Maas his description, Ps. thujicola is nothing more than a synonym of Ps. funerea.
Moroever, Ps. funerea is based on a French collection, while Ps. thujicola is based on a Japanese collection. So, even when we have to do with similar but different species, Ps. funerea would be the most probable one, a not so rare species collected in many Western European countries.
